Pardon my innocence, I'm new here, but is there such thing as a battery meter?
Suppose your flashlight runs out of juice, you find a dusty drawer full of batteries of all kinds and need two AA or 123 or D (whatever) of them re-power your light. Given it's not a good thing to mix new batteries with old ones, ideally you'd need to find two batteries that have more or less the same juice content left inside. Is there such a tool that'd help you measure battery power?
Speaking of, why is it not good to mix random batteries together?
