I assume you mean how long to charge the battery. You should never let the alternator charge a dead battery if possible. The alternator is designed to keep the battery charged but not to charge a dead battery. You put a strain on the alternator and it can cause a diode to burn out. Drive home and then put a battery charger on the battery to fully charge it. Read More

By fully charging and fully discharging some batteries the expected charge time can be increased. Some rechargable batteries will last longer per charge if they are fully discharged before you recharge them again. Recharging batteries before they are fully discharged may cause a battery memory effect that will allow the battery to run for a shorter period between recharges. Read More
