Some are 24V instead of 12V. Some cars have more than one. Etc. That said, the normal peak current is the Cold Cranking Amps. This is the amount of current the battery should provide for starting a cold engine at 0°F. 300 to 1000 Amps is not unusual. This white paper describes a dead short test:
This is the total Amp-hours available when the battery is discharged at a certain discharge current (specified as a C-rate) from 100 percent state-of-charge to the cut-off voltage. Capacity is calculated by multiplying the discharge current (in Amps) by the discharge time (in hours) and decreases with increasing C-rate.
(Recommended) Charge Current – The ideal current at which the battery is initially charged (to roughly 70 percent SOC) under constant charging scheme before transitioning into constant voltage charging. (Maximum) Internal Resistance – The resistance within the battery, generally different for charging and discharging.
OCV, impedance and conductance readings were measured and each battery was “dead short” tested using the test method described above. In theory, with a perfect conductor you are looking at over 2000 Amps. With their test, they saw 1700 Amps. And these are just 33 Amp Hour batteries, small compared to most cars. These are UPS batteries!
Charging Time of Battery = Battery Ah ÷ Charging Current T = Ah ÷ A and Required Charging Current for battery = Battery Ah x 10% A = Ah x 10% Where, T = Time in hrs. Example: Calculate the suitable charging current in Amps and the needed charging time in hrs for a 12V, 120Ah battery. Solution: Battery Charging Current:
Capacity is calculated by multiplying the discharge current (in Amps) by the discharge time (in hours) and decreases with increasing C-rate. SOC is defined as the remaining capacity of a battery and it is affected by its operating conditions such as load current and temperature. It is calculated as: SOC = Remaining Capacity Rated Capacity
