Bad battery and can it be saved?

[cb4017]

I bought a spare battery for my Mavic in November. I haven't flown much due to weather but the last two flights I've been getting a battery error with this battery. It has been charged 4, now 5 times. Today I tried discharging the battery to about 8% then doing a full charge and the problem remains. Voltages at full charge are 4.20, 4.36, 4.33.
Is there any way I can recondition this battery or should I just figure on contacting customer support?
Thanks!

Have you tried via DJI Assistant.

Send in back for warranty (6 Months I beleive?), because, IF you get it "resurrected",
would you trust it????

I had that issue with several of my batteries. I hooked up to the DJI Assistant and there was a Mismatched Hardware warning. I updated the batteries and haven’t had a problem since.
