What amount of current should I use to charge a 12V car battery?
If your battery capacity is 90Ah then 30A is C/3. The battery should handle this OK but the voltage will rise faster. Above ~13.8-14.4V (2.3-2.4V per cell) the battery will ''gas'' as the water breaks down into hydrogen and oxygen.

Your 30 amp battery charger is rated at approximately 3600 watts (30 amps at 120V).
How many Watts does a 40 amp battery charger use?
A 40 amp battery charger uses 480 watts. This is because the charger is rated at 40 amps and the voltage is set at 12 volts. The formula for watts is amps multiplied by volts, so 40 amps multiplied by 12 volts equals 480 watts.
What is battery capacity?
Battery capacity is measured in Ah, or Amp-hours. As the name suggests this means how many amps the battery can deliver in an hour. For example, a 12V lithium battery with a capacity of 100Ah can deliver 100A to a 12-volt device for one hour. The same 100Ah battery could supply power for 4 hours (100/25=4) to a 25 ampere device.
How many 12V 50Ah batteries are there?
In the picture above we see two 12V50Ah batteries. As you can see the two batteries are connected in series: the minus and plus terminals are connected together. You have created a 24V50 battery : 24V (due to series connection) with 50Ah capacity (number of Amps remains the same).
How many amps does a car battery have?
Hundreds of amperes. For example, my truck has a battery rated at 625 amps. Each battery should have a rating. Many auto parts stores have the ability to test the battery for you to make sure it is putting out the correct current. A dead short will be significantly higher than the CCA rating.
