When multiple rechargeable battery cells are wired in series, to achieve a higher voltage battery pack, cell balancing may be needed. A set of cells connected in series will all see the same current, whether providing it as they are discharged or accepting as they are charged. In a perfect world, if all of the […]

The typical voltage range for an alkaline battery is 1.55V to 0.8V as it discharges.

General What does #CA discharge mean? If the capacity of a battery is 7Ah (amps x hours), 6CA discharge means 6 x 7 x A = 42A discharge. If the battery is 12Ah and the max discharge current is 5CA, the max discharge current will be 5 x 12 x A = 60A. What are […]
