Battery Question

[fUbAr]

If i were to take a working battery off a car, how long can it be left doing nothing before it became useless?

a few months?

Depends really if its a decent battery I've left one for months before and put it on a car that didn't start and it got it going. You want to check what volts/amps its kicking out before you chuck it though.

Trickle charger from machine mart are only about a tenner or so

Put it in the fridge. It'll keep longer.

Do not put it in the freezer unless its fully charged.

(At this point you are asking yourself whether that was a joke, or a serious comment, right.)

If you are merely asking how long before it goes flat, that's a completely different question. The answer is a few months. And the solution is to put it on a trickle charger.

that does make sense actually the battery loosing its charge is a chemical reaction. Cool it down and it will slow down
