There are few types of battery in the market, those genuine ones, oem ori , (AA,AAA and so on) and of course the fake ones.

Most of the oem ori has the same capacity as the original, some may not. Even the other grades has the same capacity at times unless it was made with not the full capacity as to lower the manufacturing cost.( fake ones)


The price for getting the battery fix for ori can cost from 100++ - 300++ depending on where you fix it.

As for the others you can get is from as low as 50 - 100++.
