Do you want to know how many cells of your laptop batteries? Do you know how to calculate this?
At present the majority of laptop batteries are used in industry-standard batteries, generally fall into two types:cylindrical and square. The cylindrical batteries are bigger than the 5th batteries, square batteries are broadly equivalent to the size of a Zippo lighter size.
Current mainstream cells capacity:a cylindrical:3.6~3.7 V/2000 ~ 2200mAh, a square: 3.6 ~ 3.7 V/1800 ~ 2000mAh. According to the above figures,the number of cells in the batteries can be inferred.
Such as the IBM ThinkPad T42 standard battery is 10.8 V/4400mAh, then its cell number of batteries is 6, a series of two and three methods. Namely: Obtains 3 X 3.6V=10.8V three cells series, connects two groups after the series of cells parallel to obtain again 2 x 2200mAh=4400mAh.
But the IBM ThinkPad T42 increase for 10.8/6600 mAh battery, then several cells for 9, a
string of three and three methods, namely: Obtains 3 X 3.6V=10.8V three cells series, the
two groups After the series of batteries to be parallel 6600mAh = 3 x 2200mAh.
Generally speaking the difference of the extended battery and the standard battery lies in
increases the number of cells in parallel to increase capacity.
Then you can calculate the cells before ordering laptop batteries, do you understand?
Laptopbatterymart.com provides so many laptop batteries, you can take some laptop batteries in this website to have a try….
What about you? Do you know? Maybe your power is running low…Want to order a new battery? You can calculate before order, then you do not need to ask some else…
