Hi Guys,
With lockdown & no drone use for about 9 months, I now have an opportunity to go & take some video footage at a lovely estate here in Devon.
I conditioned my 4 batteries twice by fully charging & then discharging to 60% as recommended by what I had read, however it has been now about 6 months since I did this, (Lockdown/work/etc. etc.) & I thought I would bring my gear up to full operating ready by charging/updating everything I have.
My DJI smart controller is fine, some updates completed & now OK. Standard controller charged & all good but my 4 drone batteries, all outer (charge indicator) lights glow of green but no charge. 4 hours later, removed from my multiple DJI charger (tried it on the single charger too) & wanted to update my Mavic 2 Zoom through software updates (I believe there maybe battery updates) so I seated each battery one after the other, pressed the button, 4 seconds of a lit green outer full charge ring but no indication flashing of charge level, then no lights at all, it’s as if the batteries are switching off completely!!
I seated the batteries back in the charger & there is no indication of charge (even though if you press the button, you get a 4 second full circle green 4 section charge ring but no charge flash indication)
I hear the batteries “hibernate” but I have trawled the net but I cannot find anything that matches my issue.
Do I now own 4 (hardly used - 4x max) Mavic 2 Zoom batteries that are completely useless or is there a method to bring them back to life as I believe there are battery/drone updates but without power, I am completely knackered.
Any help would be fantastically appreciated, even if I am told my batteries are destined for the bin. (they look absolutely mint with no swelling whatsoever just for your information)
Many Thanks
Rick
