How much current should be used for the battery
batteries
For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.
