Can A Car Battery Go Dead From Sitting. Answer 1 of 4. But the sitting period absolutely depends on your vehicles model and the battery condition.
The problem with just jump-starting a dead battery is modern alternators are sometimes overworked trying to charge the dead battery and power the car at the same timeA tiny trickle charger is not the answer here. For example a 50AH battery might last 34 weeks with a 100mA drain. A car should be able to sit parked for at least a month without the battery dying unless its a higher-end car with plenty of power-hungry gadgets and computers experts say.
Its likely the battery has been damaged from sitting dead.
For BMWs and some. Only my wifes Solstice GXP can go about a month before the battery is dead. Cut down on car battery drain. We have had the battery go dead four times.
