Can you "recondition" lead-acid batteries?

[QUOTE="audiolife, post: 7170455, member: 541383"] You shouldn't jump start a vehicle with batteries resting that low it is very hard on the alternator. An alternator is not a battery charger as much as it is a bulk battery maintainer.You can try to charge it(correct type of 2 amp charger) up past 6 volts which you should keep your eye on. Sulfated batteries do not act normal at all. If they get above 6 volts I would use a charger like a ctek 7002 on it to see if it can bring it back. That would be the easiest and safest way, you shouldn't ever let your batteries get that low, if you are not driving the car for an extended period of time you are better off unhooking the batteries from the car after they have been fully charged. No 12v battery made is made to be ran down that far and when they get ran down you should recharge them asap. [/QUOTE]
