菜车电压接近14，5系不详。网络说12.5 may b alrgt

12.5 volts - Your battery is at a healthy state of charge, but we'd recommend re-checking it within a few days to ensure the voltage hasn't dropped any further. 12.1 - 12.4 volts - Your battery is partially discharged and should be recharged as soon as possible, using a suitable battery charger.

• 欧洲车很多这些莫名其妙的故障码都是由于电池问题引起的，如果电池很旧了可以考虑换掉 -bushihandyman- ♂ (167 bytes) () 08/09/2023 postreply 12:27:39

• 14v 应该是在发动机运转工况下的发电机输出，而楼主很可能静态测量电池输出，而且只量电压不能说明电池状态 -mountrobson- ♂ (0 bytes) () 08/09/2023 postreply 15:42:15

• 对。 我是在断开 (disconnecting) 电池后测的。 -数字连线- ♂ (0 bytes) () 08/09/2023 postreply 21:29:56

• 不需要断开，关键是点火时的Vmin；但是12.5V多半没事 -chinomango- ♂ (0 bytes) () 08/10/2023 postreply 13:55:01
