How many amps can a car battery supply?
The capacity of an AA battery is typically measured in ampere-hours (mAh), which indicates how much current a battery can deliver over a period of time. For example, a 2000mAh AA battery can provide 2000mA of current for 1 hour, 1000mA for 2 hours, or 500mA for 4 hours before it needs to be recharged.
Three takeaways about the current state of batteries
The alternator or the battery is probably in poor condition. The alternator will charge the battery at a constant voltage (usually 13.8, or 14.2), and electively never a constant current. The amount of current that goes to the battery will steadily naturally decrease as the battery charges.
