How long does it take the alternator to recharge a dead battery...

Dead battery being totally dead! And after that, what stops the current from the alternator from going to the battery once it is fully charged?



Thanks

Don't!
If you try to charge a dead battery with the alternator, it will fry the alternator quickly. It forces it to run at full load and burns out the diodes.

I guess I could be considered somewhat of an expert on this. When I leave work ing the morning it is still dark out but it's daylight by the time I get home so I am constantly leaving the lights on (at least twice a month) and finding a dead battery later that day. I usually jump the car, drive 10 min to the quick stop to grab a pack of smokes and back, and by that time the battery has enough charge to restart the vehicle, every is OK until I leave the lights on again. Hope that answers your question.

The alternator isn't really equipped well to charge a dead battery. It's meant to maintain the battery.

Investing in a good battery charger is almost a must for any automotive enthusiast, and that is the best way (a 2-amp trickle charge) to bring back a dead battery without excessive buildup of sulphates on the plates. Just my $0.02.

Well, I took your advice and took the battery to Discount Auto parts where they put it on a slow charge for 3 hours. It was charged up to 560 cca, the battery can hold a max. of 650 cca. I asked the guy about the remaining amount, and he said that the alternator would top that off. I'm not sure if that is all together true...

As far as i know the battery should have a full charge on it,as full as you can give it and then the alternator will maintain the voltage from there.I went out and bought a battery charger with jump start on it anyways so my battery could have a full charge.My battery was so dead and it wouldnt take a jump start.I let the charger fully charge it and then it was perfectly fine.The battery is like a normal battery for a change,cause before i gave it a full charge it would die on me even though it had enough jiuce to start the car after id jump it.

So I guess I should take it back to get fully charged. The only thing that I hate about that place (Discount Auto Parts) is that they leave the battery charging until you come in to pick it up. So it could be charging for hours/days until you picked it up. Ultimately damaging the battery. How exactly does a dead or low charged battery damage the alternator?

well basically,the alternator cant handle trying to bring the volts of the battery up from lower than X amount of volts.The alternators job is to maintain the voltage of a healthy battery.But thats all i know,anyone else?

Bishop,

Dont take the battery back for more charging. 560 CCA is plenty to get your car started, and contrary to some of the above posts your alternator will not have a problem bringing the batt. up from that amount.

I could understand not wanting to charge the batt. with your alt. when it is completely discharged, but there is not a huge difference between 650 and 560 CCA. Just take the car out on the highway during the daytime without your A/C on and cruise for half an hour. If your charging system is up to par your batt. will be fully charged.

Thanks for the advice. I'll keep the battery at 560 and let the car take care of the rest. Saves me a trip, and assures me that I'm not neglecting the car.

Thanks for all of the posts.
