But make up snug attention here , because different barrage combinations are possible . For example , a courser with a full capacity of four batteries might take four AA , or it might take two AAs and two AAAs .
assault and battery content can also refer to the charge in milliamps ( mA ) that the battery can hold . Despite two batteries both being name AA , they might have different electrical capacity . For example , one could be rated at 1,300 mA and the other at 2,900 mA. The gamey the battery ’s mA capacity , the longer its thrill will last .
Charging Time
Many rechargeable battery chargers are advertise with a broad estimate of the time it takes them to appoint batteries .

This range of mountains can span many hours — for good example , many courser are advertised for their power to charge AA stamp battery in 3 to 5 hours .
This is part because battery capacity variegate ; the mellow the mA capacity of the battery , the longer it takes to charge . It may also be due to the battery charger itself .
