Default Batteries - How many MAs and Voltage do yours take?

I have several batteries that I received used and was wondering when you decide to get new batteries. Something more specific than "when they lose their punch" would be helpful. Is there a milliamp or voltage minimum that you have?

Right now, my GP 3300s are charging between 3000 and 3400 milliamps with voltage in the high 8s from what I recall.

Wondering how much faster I could be with new batteries. I run stock, 4 minute heats, on-road, tight track, so 4 minutes is nothing to these batteries. They can do double that, easy.

Thanks for your thoughts.

As a follow-up, this elusive "punch" that people refer to. Is there a direct correlation with the number of mAhs that a battery will charge to?

Punch = Internal Resistance. The lower the IR of the packs the better the punch. Very good for stock. MAH is runtime.

Precisely, & that's why we usually say we replace them when they lose their punch. As you already mentioned, in stock racing, runtime is not an issue, so mah doesn't really matter much, though the voltage at peak can at least be a small indicator of the internal resistance of the pack(that peak voltage tends to rise when it gets older & resistance goes up), but really it's on track that you really see the difference, which is why we almost always just replace them when the punch goes away.....
