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.
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
something is causing a drain on the battery when switch is turned off
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.
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
Something is on draining the battery or it has a dead cell and needs replacing.
Forever, if you don't get "charged" again :-)
Either the charging system has failed or the battery is bad.
An iPod will not stay charged for a week, no matter how long you charge it. Everytime you use it, battery power is being wasted. Also skipping songs, and it just being on is wasting power as well.
Altenator is not charging battery!!
