6 FAQs about [How much current is normal for a battery string]

What determines the amount of current a battery can supply?

The amount of current a battery can supply is determined by several factors. The first factor is the battery’s voltage. This is the potential difference between the positive and negative terminals of the battery, and it determines how much power the battery can supply. The higher the voltage, the more current the battery can supply.
