Q: Car wont stay running with a new battery

嗨，听起来您可能会有一个故障的电压调节器，可能会为电池充电。您可能会有故障的电压调节器，可以允许交流发电机向电池提供过多或太少的安培，从而导致电池永远不会像设计时保持一致的充电。电压调节器是一个调节的单位charging of the batteryby the alternator. When the voltage regulator is not working properly, this may result in the alternator allowing too much power to be delivered to the battery resulting in damaging wires and prematurely sometimes destroying the battery. A common sign of this is usually the acid inside the battery boiling causing the battery to swell. You may also smell a bit of smoke due to things potentially getting too hot. In other cases it may result in the alternator not supplying enough power to the battery, resulting in undercharging the battery or not charging it at all. I would recommend having an expert from YourMechanic come to your location todiagnose your vehicle’s charging system.
