The discharge load in amperes that a new fully charged battery can deliver at 0 degrees F for 30 seconds while maintaining a. No current limit as long as battery temperature remains below 125F 517C.
For example we have a 100 ah and 12 volt battery so we will need 25 amp for the battery as 25 is the 25 of the ah. 138 to 150 volts. Note the DC volts reading and compare with the table below which indicates charge under no-load status.
The average car battery has about 48 amps and the amperage of a charger tells you how many amps it will restore in one hour.
