Know Your Laptop Battery
When given this question to any laptop or notebook computer user, they will get puzzled. This happens to me once when someone ask me about my laptop battery. As you can see, before you replace your dell latitude D610 laptop battery it is quite important to know a bit on the back ground first. There are several types of laptop batteries which I will share in this post.
Types of Laptop Batteries:
1. Alkaline – This is one of the common batteries around but only few laptops used it and the flaw about alkaline batteries is that is not rechargeable. You have to throw it once it goes flat.
2. Lead Acid – One of the most commons usage for this type is for laptop computers. It is long lasting, durable and rechargeable but unfortunately it is heavy and full of lead .
3. Lithium-Ion – The type of battery you would want to have for your laptop. The fast charging effect make it good for users on the go (need not wait for a long time for the battery to get charged completely). It is also environment friendly as well.
4. Nickel-Cadium – Ni-Cd batteries is one of the oldest and best performance types of rechargeable batteries but it has a major problem. After a long usage ( a few years), the acer aspire 4520 battery will suffer from the dreaded memory effect. This means that the lifespan usage of the battery will deteriorate as time goes by.
5. Nickel- Metal Hydride – Ni-MH batteries is considered to be the successor of the Ni-Cd batteries but unfortunately the dreaded memory effect is as bad as well. However as compared between Ni-Cd and NiMH batteries, the latter last longer as compared to its predecessor.
The odds that you will using the Lithium-Ion batteries are 99% ( that’s if you are using the new breeds of laptops ). Just check the abbreviation that says LION or Li-Ion on your laptop battery label. There are still a few laptops that are using Ni-MH batteries these days and you might want to check with the manufacturer whether you can do an upgrade from Ni-MH to Li-Ion. Using unapproved batteries could led to dire consequences …. so do be very careful on this. If you have a higher budget you might want to check out SMART batteries. It has a power management circuitry and it will indicate to the user what is the current condition of the toshiba pa3284-1bas battery.
Things You Should Know About Cheap Laptop Batteries
Laptop has become very important in our lives, so that the power source also very important for efficiency and survival of our laptops. If the laptop cannot be used for more than two hours the user will get stuck with a device created for speed and mobility but shut down very quickly because the electricity supply is inefficient.
There are many types of batteries such as nickel hydride, lithium ion batteries and nickel-cadmium batteries. Batteries price depends on the materials used to manufacture them. Among these three batteries, nickel cadmium batteries are the cheapest. The price of nickel cadmium batteries can range from $ 50 to $ 100.
Nickel hydride battery is a little expensive compared to the cadmium batteries. The price of nickel hydride batteries can range from $ 80 to $ 150. A lithium polymer battery is more expensive than the two types of batteries mentioned above.
Another discovery is revolutionizing the laptop battery is a new external battery that offers run-time of about seven hours in about half the price, but also depends on the programs used on a laptop. Many vendors on the internet offer cheap laptop batteries when purchased in large quantities.
Some companies offer a discount on the battery if the same company that produces laptops. Alkaline batteries are the cheapest among batteries, but bear the highest cost per cycle. Other cheap laptop batteries include lithium ion batteries and lithium ion polymer batteries. Cheap laptop batteries are also available in the Chinese market and can be sent to the United States with reservations over the Internet.
Life of a battery can be increased about fifty percent, so lowering the same price. Many preventive measures can be taken in order to increase the battery life like – fully discharging and charging the battery at least once a month back, the battery remains cold and dry, and make sure that the battery is not overcharged.
Things You Should Know About Laptop Battery Chargers
There are two types of laptop batteries consist of nickel metal hydride and nickel cadmium. We recommend that you fill in a new battery in cycles of fourteen to sixteen hours. Your battery should be allowed to cool down before charging as overcharging will shorten their lives.
The price laptop battery chargers range from $ 200 to $ 300 and have one year warranty period. Ready access to important chargers for nickel cadmium may suffer from a ‘flawed memories”.
The owner of the laptop may face this problem if the battery is not fully discharged before charging. A nickel-cadmium battery must be charged only once been completely exhausted. There are two ways to recharge laptop batteries.
First, every time the PC using the AC power, a small electric current to the battery ran called trickle charge. This fee will automatically recharge the laptop battery after it was decided. The second is with external laptop battery chargers. Battery charger plugged into, then the charger is plugged into a standard electrical outlet.
Some chargers are available in the market offering to charge the battery in seven hours, but this can permanently damage the battery. Nickel-cadmium batteries tend to break away, which means they can lose power when they are not being used.
Laptop battery chargers solve this problem by providing a small charge batteries that store the battery fully charged. Nickel-cadmium batteries work more efficiently when they are fully discharged and then recharged.
If the battery is used in a fashion that more little by little and then, sometimes fully discharging the battery before charging to the same increase productivity. Some laptop battery chargers do this automatically, but leave your laptop during the night and charging the battery in the morning also can refresh the battery efficiently.
A few things you should know about your Laptop Battery
We can see laptops every where, they’re becoming more and more popular as they are light, portable and personal to each of us. It is like they are nondetachable part of our daily life.
But behind every Laptop is lying the power source which runs everything from CPU to DVD Rom, laptop battery at the edge of technology which is getting thinner, more powerful and easier to handle everyday thanks to improvements and researches have been made. But do we know enough about them? How to charge-discharge them, how long they will run our laptop and when is the time to replace them…
Hope this following article will help you get a better understanding of a laptop battery and it’s functionality:
(1.) Does using the wireless network card drain a laptop battery?
Yes, wireless network cards do reduce the battery run time. It is difficult to quantify the adverse effect a wireless card has on battery run time because it varies depending on laptop model and wireless card. The operating system and the software installed with the card may have utilities for conserving battery life.
(2.) Does disconnecting USB devices from my laptop, help conserve battery life?
Yes, disconnecting USB devices helps conserve battery life. It has also been widely reported that a flaw in Windows XP affects certain Intel based laptops to drain the battery at a faster rate than normal when a USB device is connected.
(3.) How long should my new rechargeable battery last?
The life of a battery under normal use is around 500 to 900 charge-discharge cycles times. This is between one and a half to three years of battery life for the average user. As the rechargeable battery begins to fail the running time of the battery will begin to drain. When a battery can supply only around 30 minutes of charge, it is time for a new replacement.
(4.)What is the run time of a battery? How long will my laptop stay ‘powered’ with the battery?
Run time varies between each laptop. This makes it difficult to tell exactly how long a battery is will last. There are several other factors that affect a batteries run time:
(a.)The chemistry and capacity of the battery (Li-ion, Ni-Mh, Ni-Cd)
(b.)How old your laptop battery is.
(c.)The number of times a file is saved or retrieved from the hard drive or DVD Rom drive.
(d.)The type of software being run, i.e. some applications such as games, graphical software or wireless networking will dramatically reduce run time.
But for overall, a realistic predict of run-time for our laptops is between 1.5-2 hours (4400mah),3-4 hours(7200amh),5-6 hours(10400mah)…etc
What You Should Know about Lithium Ion Laptop Battery
The greatest advantage of owning a laptop is its unmatched portability. The battery power is a decisive factor to determine how long you could use your laptop in the place where electricity is unavailable. The most common-used laptop batteries today are Lithium Ion batteries.
Traditional rechargeable batteries might have “memory effect” that does not apply to Lithium Ion. The effect is also used to explain once there is any battery doesn’t work for us at its full capacity. In order to overcome this, people charge this laptop battery in certain ways to avoid or fix. Lithium Ion batteries’ poor performance is usually caused by mishandling or age.
Quite a few of us like to fully discharge a laptop battery before we recharge it. This is wrong. Lithium Ion laptop batteries have limited amount of charge cycles – a fully discharge will shorten its serving life span.
How to make your laptop battery pack have longer life span?
The charge cycles of Lithium Ion batteries are from 300 to 600, which could be used from 2 to 4 years. For taking advantage of your laptop battery optimally, the following things you should notice:
* If you don’t need the laptop to finish a task, don’t forget to enable the power saving feature while you use your laptop on battery power.
* Calibrate your battery with a full discharge every 30 charges for keeping its fuel gauge’s accuracy. Before recharging, set your setting to the automatic cut-off point.
* Disconnect the battery when you use AC power. If the two used at the same time, the internal temperature of the battery rises, thus the aging process of your battery accelerate.
* For battery not use for a long time, make sure that it has about 40% charge level and store in a cool dry place. Lower temperature slows down aging process of laptop battery.
* If you like to use battery to run your laptop, charge it as often as possible.
* If the outside temperature is high, don’t leave your laptop or battery in your car. Higher temperature shortens the life of your battery.

Things You May Not Know About Laptop Battery
As usual, most manufacturers will tell you that a laptop battery can run up to 2 hours, but actually not. After a certain time, the laptop battery will be running shorter and shorter so that we need more often to charge it. Laptop battery degradation will happen overtime. However, we can try to minimize the degradation by knowing some laptop battery information.
We all know that any new laptop battery usually comes empty with the laptop. Thus, it is suggested that you charge the battery at least 4 hours non-stop on the first charging. This can help to prolong the laptop battery’s lifespan. Also, it is not suggested that you use the laptop battery at all during the first charging.
Due to that laptop battery types are different, it is important to know how you should charge the battery. Nickel Cadmium laptop battery is an older type. For this kind of battery, it’s suggested that you use it until empty, and then charge it to full. Lithium based battery is another type of battery. For this kind of battery, it’s suggested that you use the battery until 10%-20% before you charge it to full.
After you have got to know how to charge the laptop battery, it is time to know about effective usage of laptop battery. On Windows base, it’s suggested that you use the Power Schemes for Laptop to control how the laptop behaves after a period of inactivity. This can greatly reduce the drainage on the laptop battery. Also lowering the brightness of laptop LCD monitor is a good way to reduce the laptop battery usage.
After knowing these laptop battery information, you should be able to know how to prolong the laptop battery lifespan and also maximize your runtime when running on battery.
Do You Know How to Take Care Your Laptop Battery
When you buy a new laptop, you probably don’t think too much about its power supply system, but the care and feeding of batteries is perhaps the biggest single factor in your laptop’s ease of use. If you’re keeping your present outfit, then you’ve already got whatever power supply came with it. This quick review of batteries can help you choose your next laptop, while reducing battery hassles with your current one (no pun intended). And multiple batteries are highly recommended for any outfit. We’ll look at types of batteries, methods of keeping them charged and strategies for using them.
In the dim and distant past (a couple years ago), laptop batteries came in five different species. Now, lead acid bricks and drugstore batteries cell are about gone and even lithium ion (Li-Ion) batteries are obsolescent (but see the nearby sidebar). Today, we’re down to mostly nickel metal lithium ion (Li-Ion) models.
Both types have a good weight to power ratio: that is, they can store and deliver more (longer) power than older types of the same size. They also keep a steady voltage level through more of their discharge cycle. Older battery types could drop below the voltage required by the camcorder even though there was plenty of juice left in them.
Both types are long lasting, though Li-Ion designs are the true long-distance champs. A word
Obviously, batteries discharge during use and you have to tank them up again. Some camcorders still charge batteries internally, but many models come with an external charger. If you’re shopping for that new camcorder, check its charging system carefully, since an external charger will allow you to keep shooting with one camcorder battery while the other is charging.
First, ensure that you can charge laptop batteries via 11.1-volt car cigarette plugs as well as 120-volt wall power. Holidays, picnics, weddings just about every kind of event involves driving someplace, sooner or later. Many campers and RVers live on 14-volt DC exclusively. Drive time is an ideal time to charge laptop batteries, especially if your system includes quick charge capability.
“Quick charge” typically means that the charger works very rapidly, often replenishing a laptop battery in one hour or less. But on some appliances, it’s just a selectable mode that provides a quick-and-dirty juice-up, rather than a fully programmed recharge.
You see, batteries are filled like gas tanks: quickly at first, more cautiously when the tank is nearly full, and in short trickles when you top off the fill (even though the sign on the pump says not to). A properly programmed charging system does the same thing and delivers power longer during the battery’s next use. It also prolongs its working life overall.
After 12-volt operation and programmed recharging, the next feature to look for is multiple battery capacity. A few chargers will juice up two bricks at once, which is a great time saver for power users (pun intended).
Whether buying a new system or using your old one, you need to know when to charge your batteries. Different people have different theories about this, but the following procedure is safe and effective:
Recharge a spent battery as soon as possible after use. While this isn’t critical, shallower charges of Li-Ion batteries put less stress on the battery than a deep full charge. Besides, you never know when you might meet Elvis. Do not leave the battery in the charger after the indicator says it’s fully replenished. (Don’t leave the battery in the laptop either.) Store the battery at room temperature. Stashing it in the fridge to slow battery drain is pointless if you… Top up the battery again, just before your next shooting session, to compensate for power slowly lost while the battery was on the shelf. Unless you’re using old NiCds (see sidebar) it’s not necessary to “condition” a battery by discharging it down to one volt before recharging it. A periodic full discharge is not required for lithium-based batteries and, in fact, a partial re-charge produces less wear than a full charge.
Finally, don’t expect even the most tenderly nurtured batteries to last forever. Each time a battery is recharged, it accepts a minutely smaller amount of power than the previous time, until eventually the poor baby is pooping out after ten minutes of shooting. If you’re a weekend warrior taping birthdays and vacations, expect your batteries to last for years. If you shoot weddings professionally, budget for frequent replacements. One manufacturer suggests that its batteries will last for 400-800 charges, although we find that range to be a little too broad to be useful.
Perhaps I’m paranoid, but manufacturers do change battery designs from one laptop to the next, and they do eventually stop supporting their oldest models. For that reason, I bought more batteries than I ever use at one time, so that each requires fewer recharges per year and therefore lasts longer.
Power as you Shoot
How many batteries do you really have to have? That depends on many factors. The older the bricks, the faster they quit. The more you shoot per hour, the more you need.
The trick is to compare your charger speed to your shooting demands. For instance, I typically blow through a battery twice as fast as my charger can resuscitate it. For this reason, I run three batteries, starting every session with all three charged. When the first is empty, I stick it in the charger and by the time the next two are shot, the first is ready again. That way, I have the equivalent of four batteries per session. In my case, that gives me an honest 2.5 hours of shooting time, which is more than enough.
Your needs will certainly be different, but you should have at least one spare battery for backup. Remember that battery capacity ratings are about as realistic as EPA gas mileage figures. If the manufacturer promises 60 minutes, plan on 40 to start, slowly tapering down to 15 minutes before you replace that battery.
If you do shoot a lot, consider an external battery pack: either a block that you clip on your belt or sling from your shoulder, or even a belt. You can find models for many camcorders (especially professional three-chip models) and many allow you to power an external light as well. Even if you use the built-in camera light, you’ll have ample power to blaze away without compromising your shooting time.
No matter how many units you run, you want to make each one last as long as possible; so here are some tips for conserving battery power. First, never use a built-in laptop light unless you absolutely have to. Lights love juice like mosquitoes love blood.
Next, don’t leave your laptop on standby for any length of time, especially if you’re using auto exposure and focus. Remember: your unit goes right on adjusting the aperture and focus whether you’re shooting or not and each adjustment is made by an electric motor powered by your battery. Even when actually recording, you’ll conserve juice if you can shift one or both controls to manual. This can apply to image stabilization as well, so plop that laptop on a tripod and turn off the stabilization.
Another big power drain is the zoom lens, which is always motor-driven. Try to avoid lots of zooms in shots (they look amateurish anyway) and when you re-frame by zooming, pre-visualize your new composition so that you can zoom right to it, rather than hunting around for it.
Also, remember that batteries give up quicker in cold weather. When shooting on the slopes, keep spare batteries as close to your warm self as your pockets permit. If you won’t be shooting for a few minutes, remove the battery already in the camcorder and get it toasty as well. When you replace it, you’ll get quite a few more minutes out of it.
So: look for lithium ion designs when shopping for new gear, keep your batteries topped up properly, carry enough to keep shooting and don’t expect them to last forever. And that’s about it.

Know The Basic Identifiable Parts Of A Laptop Battery
Just as the fuel determines the mileage of an automobile, it is the battery that predicts the life of a laptop thus, a laptop with a defunct battery is of no use. Assembling a laptop battery involves meticulous placement and segregation of its various components on the basis of their functions. In the last few years, the production of laptops has expanded at a rocket speed in order to meet the great consumers demand. But, the secret behind the success of laptops as an excellent mobile computing device is purely due to the efficient and increasingly user-friendly modified versions of laptop batteries.
In other words, ‘portability’ is the underlying USP for the widespread sale and popularity of laptops around the world. The components of a laptop determine its identity and each component holds an important role in the overall battery life. As a matter of fact, it is the ‘cells’ that give portability and high density of energy in mobile computing devices.
In every laptop battery there are few basic characteristics such as capacity, chemistry, voltage, cells, wHr, color, cell manufacturer and weight. Most importantly, the capacity of a laptop battery directly tells the power or energy output of the laptop, also a laptop battery undergoes immense changes in its attempts to complement with the lightness of the product. Irrespective of whether the replacement battery is purchased during a discount laptop battery sale or procured ‘freshly arrived’ stocks, 100% replacement compatibility with the original battery is a must. Over the years, technology has evolved to suit users in every aspect of mobile computing where ‘laptops’ have become the ‘buzz word’. Presently, Ni-MH and Li-Ion are the most widely used chemical components in the making of laptop batteries, and the lightness of laptop battery is largely credited to the advent of Li-ion based laptop battery. Why lithium? The reason is that lithium is one of the lightest metals used in the manufacture of mobile computing batteries.
In addition, battery cells play an important role in the overall value of a battery and the number of their use varies from one battery model to another. For example, the cell of a Li-ion based battery is usually 3.6V cylindrical and has practically no memory effect but contains longer storage life compared to NiMH battery cells. Nowadays, they are more compact and have high energy density allowing them to become one of the most prevalent types of cells. Hence proved, the reason why this type of battery is more popular both among manufacturers as well as users.
To illustrate with an example, a Compaq laptop battery of the model Presario 2103 2150 2170 Battery has 8 cells while another with model no. C300 V2000 M2000 Battery has only 6 cells. It is extremely important to note that every pros and cons is taken into account regarding the compatibility of the replacement battery with your device before procuring one. In some cases, some devices may allow the battery to be upgraded from Ni-MH to Li-ion, doing this is known to extend the life of the battery manifold. Low cost or cheap laptop battery is an economical option for most of the laptop buyers on the look-out for replacement battery, but one must be skeptical and picky during the shopping spree for cheap battery.
