Default Battery Questions ???
I have a Ancel battery tester and was wondering what the internal battery resistance it is showing ? My tester says it's 3.4
My question is how do you know when it's time to replace and what is the resistance test ? Did a search and couldn't fins any infor on it.

Should be nearly 0, like .03ish, on a good battery, but why are you checking resistance instead of the other test functions of that unit?
