How many amperes of battery can be charged with a current of 3 5 amperes
A car battery provides 12 volts at around 13 amps. That means it can deliver enough current to start a car or run a light bulb. If you want to know how many amps a battery delivers, multiply its capacity (in amp-hours) by 0.13. For example, a 24V battery rated at 15 amp hours would give you 2.4 amps per hour.
