using laptop battery’s Tips and Tricks
Laptops are by definition, portable computers. In order to secure this portability, the laptop battery is crucial. Unfortunately, most laptop batteries die young, sometimes even in the first year of life.
The “Memory Effect” of a laptop battery
“Memory Effect” is a condition of reduced battery performance, or failure, due to a battery only using those cells that are fully discharged and charged on a regular basis. If on a regular basis a NiCd or NiMH battery is only partially discharged before being recharged, it “forgets” that it has usable capacity to further discharge all the way down. The result is loss of performance and shorter battery life because the battery is using less than its true full capacity.
NiMH batteries, while considerably better than their NiCd counterparts, are prone to developing “memory effect.” However, proper care and conditioning over the life of a NiMH battery will significantly reduce the potential negative impacts.
Li-ion batteries do not develop the “memory effect”. Nevertheless, there are a few laptop battery tips that you should follow, in order to maintain it fully operational as long as possible.
What to do with the battery when using the laptop as a desktop?
If this is your case, it’s better not to keep the battery in place for a long time, as the laptop will then discharge the battery over time. Don’t store the laptop battery for long periods either. Use it at least once in 3-4 weeks.
Tips for extending you laptop battery’s life
Everyone wants longer battery life, within reason there are some tricks to help get the most out of your laptop’s battery. For instance, make sure that you disable wireless networking when not using it, as it consumes power on continuously searching for wireless networks available (it does increase the usage time with only a few minutes, but at the end of the day, all these small things add up). It might die too soon anyway, but at least you will know that you did your best to keep it as long as possible. You can use additional devices for extending a laptop battery life. For instance, Electrovaya PowerPad is a device that can extend your battery duration up to 16 hours of use without recharging.
All tips and tricks on using less power while operating on battery are good to be known and applied if they fit your needs.
One more thing: when you buy a laptop, always ask for info on its battery type, characteristics and warranty period. Some shops give only 6 months warranty for the laptop battery, but this is written so small in the contract that you see only that the laptop has one year warranty (this happened to my laptop battery, which died in the 7th month of its life, too late to be replaced on warranty
www.mc207lla.net Inheriting technology and design features from the MacBook Pro line, the new MC207LL/A has been updated with a durable polycarbonate unibody design featuring a brilliant LED-backlit display, a glass Multi-Touch trackpad and Apple’s innovative built-in battery for up to seven hours of battery life. Measuring just 1.08 inches thin and weighing 4.7 pounds, the sleek new MC207LL/A cuts a slim profile on any desk (or in any backpack or briefcase). And it comes with everything you need for email, calendar, contacts, browsing the Internet, and more–all a part of the pre-installed Mac OS X Snow Leopard operating system.
Bad Habits of Using Laptop Batteries
Maintaining batteries has been a hot topic for laptop users. In fact there are many wbad habits of using laptop batteries, and these mainly come from 2 aspects. One is that the thinking hasn’t kept up with the change of Ni-MH batteries to Li-ion batteries. The other is funnier, as the mobile phone using the device repeatedly rechargeable batteries is the first contact to most users of laptop. So the using habit of phone has been taken for granted to extend to the using of laptop.
Here are some common bad habits of using laptop batteries:
1. New laptop battery need repeated three times of charging and discharging to activate it.
You needn’t to do this unless you have bought a laptop which has been stocked for longer than one year. Because the battery cores have been activated in the factory, and when the battery cores are packaged to laptop batteries, there is an activating test. So when you got a new Dell INSPIRON 6000 Battery, it has been active. If you do three times of charging-discharging is to increase the batteries life only.
2. The first charging must be enough for 12 hours
This is fit to the earlier laptops using of Ni-HM batteries with no control circuit for battery. Now, it’s a fun to the laptops with intelligent control circuit of charging and discharging. When the battery is full charged, the charging current is automatically cut off. Even if you continue to charge 120 hours, there would not be any change. In general, even the charging slowest laptops; 6 hours charging is enough, remaining charging is just waste of your time. Instead, you need to charge the battery first when you get a new Dell Latitude D620 Battery.
3. Battery requires periodic calibration, fully charging and discharging once a month.
For Ni-HM batteries, this is necessary, but it’s too frequent to Li-ion batteries. 1 times of 2 months or 3 months.
Though the memory effect of Li-ion battery doesn’t eliminate completely, but it has been greatly reduced. If you use the battery frequently, you should discharge its power to low about 10%~15% before recharge. If you discharge the battery to the laptop won’t boot, there is great damage to the Li-ion batteries.
4. Calibration can enhance the battery capacity.
The so-called correction is that when the battery’s actual capacity and the control circuit is not the same as the record of capacity, do an operation of fully charging and discharging battery. So the control circuit record, bringing them closer to the actual situation of the battery. This is a manifestation of the true capacity of the battery operation rather than enhance the capacity.
The key factor is the actual capacity of the battery. If the battery’s actual capacity than the control circuit is higher volume record, calibration can make the battery appear to increase the capacity, but if the battery’s actual capacity than the control circuit record the capacity of the lower, then the correction seems to reduce the capacity of the battery. That’s why many people debating the causes of calibration results. Remember that the calibration is to make the battery true capacity appears, to eliminate the deviation of between battery and control circuit. As demonstrated by the increase or decrease capacity, which is the state of the battery itself, rather than determined by your calibration. There may be great hurt to battery when the battery depth of discharge, and capacity would decrease.
5. Compatible battery charger can also be used.
If you need to use a compatible battery charger, you should note that the voltage and current of the charger must be consistent with the nominal value of your laptop. The different products of one factory may have the same interfaces, but the voltage and current may be different.
6. Storing batteries with full charging or full discharging.
It’s both wrong to store batteries with neither full charging nor full discharging. To store battery with full discharging lose the activity of the battery, and it’s danger to store batteries with full charging. It’s best to store batteries with 40% power, and store them in a cool and dry place.
