Hello,
I purchase an additional DJI Battery for my Mavic zoom about 1.5 years ago. The battery has approx 10 charge cycles I have maintained the battery, but upon attempting to charege battery yesterday, the battery was compeletly dead? I looked at the labeling on the battery and it is slightly different than my other 2 batteries which are fine....This battery lists a website www.bis.gov.in....the other batteries do not show this....I purchased this battery through the DJI Website...Has anyone seen this before? Thanks

It could be in "hibernation" mode

Thank you Flycaster,

I just discovered one of my "new" P4 batteries has also suffered the same fate....This seems to be happening to newer batteries rather than the older versions....not sure why?
