Q: Laptop Battery Capacity 4400mah, 5200mah or etc: What is mah and 6 cell or 9 cell ? and if it is different than the original battery capacity i.e 4800mah, 5800mah, 8800mah etc?
Will it still fit and work in my computer?
"Milliamps Hour (mah)" and "number of cells" is the strength or capacity of Lithium Ion Rechargeable battery. The higher the mAh, the longer the battery will last, means more discharge time. Batteries with different mAh ratings are interchangeable.
Battery capacity, Volts or no of cells can be different ie 4400mah, 4800mah, 5200mab, 6600mah or similar like this.
It will still fit and work in your computer without any problem. Higher or Extended capacity works for longer time(run time/discharge time)
Only Some of the longer capacity batteries like 9 cell 7200mah or more are bigger in size but they will still
work in your computer. Some of these batteries like 9 cell or more sticks out and protrude out the (bottom/side) of the laptop and may cause your laptop to sit at an angle. But It is better for Laptop as it create good air circulation and does not cause CPU to become. But our item for 21st Century Scientific Battery works fine.
