Suddenly silent battery...

[jangai]

Hello, After a sleep of 2 months at 50% of my 3 batteries of MV2 Pro, two flights yesterday and today : one of the 3 batteries behaves normally for reloading, but no longer communicates with the drone: 0 indication on the battery tab into DJI GO ! My batteries have between 23 and 33 charges.
I vainly looked for the procedure of reset of the soft of the battery, of times that ... Does it exists ?
Apparently, no problem with connectivity. Purchased from a UK supplier on eBay : it fears for the guarantee, if it is still ...
Thank you for your possible advice.

Try some plastic friendly contact cleaner on the battery terminals.

Thanks for your help, but it does'nt solve the problem... I think to an internal and definitive internal failure.
