Left my car battery on for a good 6 hours, battery dead

[therock911]

While at work today I left my battery on six hours, it was dead completely.... But I got a boost and drove it for 15 mins on the highway, what are the chances of the batter/car working tomorrow morning? Also I know my batter comes with a 7 year warranty Im guessing this will definitely not be covered?? Time for a new battery or do I still have some hope? (I purchased this batter for $150 in August of '05 - yes I know I got ripped off)

it should be ok, maybe you should of drove it a bit more to let it charge up.

or you can hook up battery terminals at home and charge your batteries there

I've left it for over 8 hours, got it jumpstarted, and seen it last me 3 more years, until I sold the car.

So yours should be fine.

Hopefully it's not that cold overnight, I heard it affects it?

If you need to buy a new one, go to Costco!

how do you leave your battery on?!

how do you leave your battery on?!

Head lights/dome light will drain it

I don't think the battery is dead completely. It just need to be recharged.

This is why I don't like car that cannot cut the power itself. The battery of my previous car, civic, drained the battery just because my daughter did not close the back door properly. The car was in garage and we stayed home for 2 days (did not get out and used the car).

Th OP left the lights on, not the battery.

The battery is fine, it just needed to be recharged, don't go buy a new one.
Batteries die all the time, it happens.

It is technically winter, so leaving your dome lights on will simply drain your battery faster than it would in the summer. 6 hrs is actually pretty good at this time of yr.

As long as your battery is fully charged and you don't leave any lights on, you shouldn't have any issues.

Best thing to do is to hook it up to an automatic battery charger and let it charge fully. A dead battery can put quite a load on the alternator...I don't think an alternator is really designed to charge a dead battery and keep your ignition system and all the accessories running at the same time.
