Dead battery question?

I just bought a new battery and went into the hospital for a while and it went dead. How long must I run my jeep (YJ) to get a good charge back. Thanks

With the price of gas being what it is it might be cheaper to buy a
battery charger.

1. If the battery was completely 100% dead (discharged,) it should be
replaced. One or more cells are likely sulphated or otherwise damaged.
2. The alternator is not normally capable of doing a full recharge. To
use the alternator to fully charge a completely discharged battery would
take between 10 and 20 hours of running typically.

If you must try to recover the battery, I'd recommend a quality charger
that can de-sulphate cells in addition to charging. Most of the smart
chargers can do this. This may recover the battery sufficiently that you
will get some life from it (but its life will be seriously limited by
this...)
