I guess just how to read the battery ..it just has rows of numbers and letters..how to know what amp it is..
Can you tell us what type of batteries you have, or what type you're looking at? I don't fully understand what you are asking.
Again, what type device are you using them in?
What ohm coil are wanting to use?
I'd be happy to help, you haven't given enough information.
If you have the batteries, post the brand, and all the information printed on the battery, and we can help you determine what Amp they are.
