the ideal current or amps to charge a car battery are 20% of its full capacity e.g 10 amps for a 50Ah battery the ideal charging current for a 12v 7ah battery is 1.4 amps maximum charging current for 100Ah battery should not be above its 20% of full capacity (20 amps)
Factors like battery type, capacity, and state of charge influence how much current is needed to charge a 12V battery. Generally, the charging current for a 12V battery is around 10% of the battery’s capacity.
For deep-cycle batteries, a general rule of thumb is to charge at 10-13% of the battery’s 20-hour capacity rating. For instance, a 100Ah deep-cycle battery would require a charging current of 10-13A. Imagine you're charging a battery, and it's kind of like filling up a water balloon.
For example: In a 12V 45Ah Sealed Lead Acid Battery, the capacity is 45 Ah. So, the charging current should be no more than 11.25 Amps (to prevent thermal runaway and battery expiration). Importantly, if you have other equipment connected to the battery during chargning, it also needs to be powered, so you need to add that to your calculations.
The current required to charge a lithium-ion battery can vary significantly. While the traditional guideline is to charge at a rate of 0.5C to 1C (where C is the battery’s capacity), many lithium-ion batteries can safely be charged at much higher rates. Why the Preference for Higher Charging Current in Lithium-ion Batteries?
If the rating is too low for the equipment, it will attempt to draw more electricity from the supply than the supply can provide, and it will get hot and perhaps explode. When it comes to amperage when charging a battery the amount of amperage you are supplying does make a lot of difference and it surely does matter.
