An average car battery has a capacity of around 48 amp hours; when fully charged, it delivers 1 amp for 48 hours, two amps for 24 hours, and so on. Staying updated on the car''s battery amps is very important not just for replacement but also for powering other electric facilities, including lights, navigation, and devices.
The amount of current that goes to the battery will steadily naturally decrease as the battery charges. Immediately after starting the car it may charge at a high rate, like 50 amps, and then quickly go lower, like 5-10 amps, and eventually very low, like below 1 amp, as the battery is charged. The voltage should remain about the same at all times.

When a 12-volt battery is fully charged, it should read between 12.4 and 12.8 volts on a voltmeter.Any reading above 12.9 volts indicates that the battery is overcharged.
12.3 – 12.4 volts: Your battery is about 75% charged or less and needs to be recharged at this level. It is recommended to use a battery charger and not rely on your car''s alternator. 12.1 – 12.2 volts: The charge level is about 50%, and you should connect a battery charger immediately. 12 volts or below: At 12 volts or below, you could damage your battery and shorten its working life.
$begingroup$ The charge voltage depends on the battery chemistry. Some lithium ion batteries are charged to 4.2v, some to 3.6v, etc. And the battery voltage will vary with the current charge state - less charge means less cell voltage, but the relationship is not linear (quick drop from completely full, flatter plateau for a while, quick drop again when getting low).
