so in short, yes it is dead. next time start the car once every 2 weeks at least, and disconnect the ground from the battery if you are going to let it sit.
In this video, I investigate a Makita 18V LXT battery that appears to be completely flat—reading zero voltage and refusing to charge.
When I check the pack output voltage without the BMS it''s around 21 V (very low, undercharged). When I check the BMS output it''s around 17 V which becomes 0 V under load. I think
Seeing 0V on your lithium battery? Learn the real causes—like BMS shutdown or cell failure—and how UpFix safely revives your battery with expert repair.
After about a minute I turned off and rechecked the terminal voltage and it''s still at 0 across any of the wires. Not sure if the battery would need to be opened up and try to wake up each cell individually.
