I have a 12V 8Amp Lead Acid Battery. Here is the question:

Imagine that battery was old, but still working, and the label was torn off. How do I figure out that that battery is 8Amps?

I just want some kind of meter to read 8Amps, or some mathematical equation that will equate to 8Amps.

I know how to measure the output voltage with a voltage meter. That's not the problem.

I figured there would be a little ohms law in the equation, but never understood where to begin.

If anybody could simplify this down for me, it would be much appreciated.

Thanks so much,

Benjamin
