Replace battery or charge it?
« on: February 19, 2006, 06:34:10 PM »
The idiot woman I am unfortunately married to decides to leave her car door open and totally drains her battery (it reads 1 whole volt). Would it best to just get a charger to charge it or buy a new battery

Divorcing her would be cheaper in the long run by far since I dont got no kids

If the dome light drained it overnight, the battery may be shot anyway.  How long was it on/open?  How old is the battery?  If its more than 4 years it may be time to replace it anyway as well.

Put a trickle charge on it. If it holds a charge, don't bother getting another battery. Is this a difficult problem to figure out for men? :lol

I like that idea the best, even though she'll get a lot of my stuff that she wont have no use for.

battery might be 2 years old, door was open from sat morning to sunday afternoon, about 26 hours.

if the battery isn't that old, charge it and it will be fine.

Give it a charge and see.  If it holds the charge, you're probably good for another couple of years.  If you don't have a charger, you need to let the car run for at least half an hour to start building up a full charge again.  If your commute to work is long enough, start the car early, let it idle a while before going to work, and then drive it to work.  Toss some jumper cables in the back just to be safe :)  If it keeps starting in the morning, you're probably fine.

If you think you'll need the battery to be good for more than just going to and from work, then you really should trickle charge it with a charger.  Sooner or later it's gonna go though...

When my last car battery died, it went all of a sudden.  The engine started freaking out, idling at 3000+ rpm as the car tried to maintain voltage and charge a toasted battery back up.  I had been on my way to lunch, but I diverted straight to a parts store and got there before the engine quit or the alternator burned up.  They don't usually go like that though...

A dead battery is not the same as a depleted battery.  If you run a battery down it loses its charge but that by no means results in it becoming defective.  Just charge the sucker back up and go on with your day.

My boss just got a new truck from another contractor, 2005 van and the battery was already shot after just 75k miles. The day I picked it up the battery was dead, we charged it up, I loaded up, and the battery was dead again. So I had to leave the van running all day as I dropped my packages off. 2 days later I just finished with my 7th stop and the battery was dead again. I replaced it next day.


She probably left the headlights on too. Just charge it up, as long as it holds the charge it should be fine.

If  a battery gets TOTALLY drained it can die in the process. The plates inside the battery get a resistive coating or something if I recall right.

With a decent charger ($40 at your nearest quick-e market) :) it should start taking the maximum load immediately (usually 4-6 amperes) if it won't, replace it straight away.

Yes. The lead plates begin to decay, and that reddish substance you've probably seen is Lead Sulphate. Battery is porked if you've got to that stage. In Meat's case, given how short a time the battery was discharged, a charge up should be fine. I had a similar thing happen when I got rear ended by a truck - the damage partially opened the hatchback, leaving the light on inside. Had to take the bulb out until repaired!

A few years ago I was working in the USA for a couple of months,  and left my own car at home in the driveway. I thought I'd turned the alarm system off with the special key, but when a friend came to run the car in my absence, off went the alarm! He couldn't start the car - the battery was very low, and it was another month before I could attend to it. It had one of those window things that looks like the RAF emblem when fully charged - blue circle, red dot. Mine was totally dark. Very much to my surprise, a 12 hour charge with a fairly up-market charger completely restored the battery, and I had no further trouble...

...one of the brakes had seized on though. :mad:
