how long do batterys work for a car?
Don't charge it frquently.
Materials will stay charged as long as the electrons have no way of entering or leaving the materials.
something is causing a drain on the battery when switch is turned off
A fully charged good battery is designed to last 21 days in the newer vehicles How old is your battery?Check parasytic load on vehicle should be .07 amps
ALTERNATOR OR THE BATTERY GROUND WIRE Have you tried checking your Alternator? I know this is why mine on my vehicle would not stay charged..
At least 3-5 hours. I charge mine three hours when it's low on battery.
Something is on draining the battery or it has a dead cell and needs replacing.
they should stay charger about 2 full hours if ou charged it until the little battery turns green. ive found out tho the more you use it the time goes down a bit, but still not to fast
Forever, if you don't get "charged" again :-)
Either the charging system has failed or the battery is bad.
Altenator is not charging battery!!
Dead cell in battery or something is on pulling power from the battery. Disconnect the negative battery cable overnight with the battery fully charged (12.6 volts). If the battery is dead the next morning it has a dead cell and needs replacing. If however the battery is still fully charged then a light is on somewhere or a relay is stuck closed.
