This is a video of how to open your battery case, we do kinds of battery repair work for our customers overseas,and tell them how to do this,and the first step is to open the battery case, some of our customer think that open a case is hard work,and sometimes if they do not open successfully, the battery case will be destroyed, or they use uncorrect ways to open case,their hands will be hurt, so here i take the video,and let all my customer who do battery repair work to learn how i open the case.recell work, test battery,discharge and charge battery need kinds of equipment, my website web: www.1bu8.com we sell kinds of software and hardware , you could go to website web: www.1bu8.com to find what you need, we also provide technical support to our customers who are battery repair beginners, contact us by SKYPE:xitonghan or MSN: firstname.lastname@example.org Welcome to visit our website, hope that we could have chance in coooperatiion!
How to Change cells for your laptop battery
At present, articles about how to purchase and use notebook can be found everywhere, but on how to solve the notebook computer failures are rare. For this reason, Hunt360 International decided to exposal knowledge about how to change cells for your notebook computers battery.
Hunt360 is a dedicated laptop battery online shop companies,specializing in laptop battery replacement, Camera battery replacement, Solar battery and charger. Recently, Hunt360 and Mr. Luo made contact and asked him to tell us about the massive numbers of visitors to the laptop battery for batteries are all kinds of knowledge.
For notebook computers, the importance of the battery is self-evident. Laptop battery internally by batteries and protect the plates, batteries for electrical storage, protection of board is responsible for safety at work. Batteries are consumable items, each with one will cause the attenuation of volume, it will have a direct decision of laptop battery is good or bad.
Laptop battery life become shorter, notebook batteries can not be used, laptop battery suddenly power down (for example: battery suddenly from 40% to 10%), dissatisfaction with rechargeable laptop battery power (for example: battery charge to 30% -40%, not moved), laptop computer battery There are a lot of unused capacity in the sudden shutdown, all the above conditions are likely to be dropped or the batteries capacity damage caused by batteries. Of course, there may be due to the protection board hardware is damaged, but this possibility is very small.
Laptop battery cells
If you find that your laptop failure to occur, it is necessary to deal specifically with laptop battery repair operations of the companies to check. Next, we will give us a presentation to the laptop batteries for the whole process.
First, we use professional equipment to detect cause of troubles. there are many kinds of battery fault detection instrument , such as: Texas Instruments product, MAX products, Ateml products, and even some personal home-made products. Our company is the most commonly used Texas Instruments (Texas) EV2300.
Once battery failure is detected, there should be prepared to change battery cells for laptop battery
Circulating a statement online – laptop battery fails, you can charge and discharge into the refrigerator or deep, or pulsed current activation ways to repair it. This argument is wrong.
If it is Ni-MH batteries or nickel-cadmium batteries, does the depth of charge and discharge through the means to conduct part of the repair (not fully repaired). However, we now use laptop computers are equipped with lithium batteries. Lithium battery failure, the basic batteries are negative because of the collapse of material occurs. This situation is not reversible, so can not be repaired by the above method. Can only be decrypted by replacing battery cells and unlock to repair it.
In general, the laptop battery can be divided into three parts: the shell, cells group and the protection of electrical panels.
Protection plate back equipped Serial EEPROM memory chips
To decrypt and unlock the protection panels are two different things. We have to decryption to enter the battery management system, and only on the battery management system that we can change the battery all the parameters and use of information. If only change batteriy cells, not unlock, then not achieve satisfactory results.
We use professional equipment and related software to decrypt the protection board to unlock. Of course, the battery management chip design according to different manufacturers, choose the appropriate equipment.

How Many Cells Are In A Apple A1080 Laptop Battery
Question from a reader: “How many cells are in the APPLE A1080 Laptop Battery? The battery is for a APPLE A1080 and its technical ratings are Li-ion, 4400.00mAh, 14.40V.”
The question from the reader is a great question for it gets to the heart of battery manufacturing and begins to unravel the power of a battery. The answer is simply: 8 cells. But what does the answer mean and how does the number of cells relate to the overall value of a battery? Let’s find out…
18650 is a 3.6V cylindrical Li-Ion cell. 18650 has no memory effect (distinguish between digital memory effect) and longer storage life than NiMH battery cells. 18650 is light weight and has a high energy density. It is in effect perfect for building batteries for laptop and other portable power devices.
The additional technical specifications for the 18650 battery cell include:
Nominal Voltage Average 3.7 V – the concept of nominal voltage is that voltage range exists depending on the number of cells in the battery.
Nominal Capacity – 2200 mAh (above 2200 the stability of lithium based cells is called into question)
Max. Charging Current – 2.4 Amps Max.
Max. Discharging Current – 4.6 Amps max.
Dimensions (DxH) 18.3 mm (Max 18.4) x 64.9 mm (Max 65.1)
Weight 46.5 g (1.64 oz)
Internal Impedance: less or equal to 90 ohms
Cycle Performance is 80% of initial capacity at 300 cycles
Now as stated above the reader asked how many cells were in the APPLE A1080 Laptop Battery? The battery is rated at 14.4 volts and a capacity of 4400 mAh.
As I mentioned above the nominal voltage average is 3.7V. Some manufacturers may use 3.6V and some may use 3.7V. In the case of a laptop battery with 14.4V the nominal voltage rating used is 3.6V. Thus if we divide 14.4V by 3.6V we get 4. Thus 4 cells in a series. We also know that the batteries capacity is 4400 mAh. We know the nominal capacity is 2200 mAh. Therefore if we divide 4400 mAh by 2200 mAh then we get 2 in parallel.
Therefore we have 4 cells in series X 2 cells in parallel equals 8 cells in total.
