No, you cannot 'restart' a dead battery in the sense of restoring it to full health if it's truly dead (as in unable to hold a charge). However, if the battery is not fully dead but just discharged, you may be able to recharge it using a battery charger or by jump-starting your car and letting the engine run to recharge the battery. If the battery is old or truly dead, the only solution is to replace it.
