How Many Amps Does A 12v Battery Have. The internal chemistry of the battery will also affect the amp rating. In the article I have explained what the amp is why it is important and how to test it.
A typical car battery with 12 volts rating has a capacity of 48 Ah. Many auto parts stores have the ability to test the battery for you to make sure it is putting out the correct current. While both are typically 12 volt batteries a motorcycle battery has less Amperage and requires less amp charge rate.
It means that when fully charged the battery can deliver one amp for 48 hours two amps for 24 hours and so on.
While both are typically 12 volt batteries a motorcycle battery has less Amperage and requires less amp charge rate. A rule of thumb is that for a 1 hour discharge rate ie. A typical car battery with 12 volts rating has a capacity of 48 Ah. And thats the same for similar ratios.
