How is the Battery Discharge Rate Calculated? (Here is the Full Procedure)
For example, a battery with a maximum discharge current of 10 amps can provide twice as much power as a battery with a maximum discharge current of 5 amps. This number is important for two reasons. First, if you are using a device that requires more power than the battery can provide, then the battery will not be able to power the device and it will shut …
