Buying a used second hand Oem battery
Thinking of buying a 2019 Bmw m4cs battery used
It’s dated on 2019 How can I check to see if the battery still good or how I can ask him to show me to see if the battery is good? What do I look for? Thank you f80 family |

At minimum it should show a voltage at the posts, ~13.2v.
That's the avoi the case where the internal BMS disconnected the battery to protect it from undervoltage, so it would show 0 volts. Besides that, I don't really know, since it's not a traditional lead acid battery. |
