Batteries were in storage for a long time when I bought my used drone (Mavic 2 Pro), and now some of them seem to be dead (no LEDs at all), but some work fine. They are the same age, so I think the cells are OK but they were in hibernation mode for too long, but I can't bring them out of it.
DJI Fly App Updates with New Battery Icon Indicator for the Mavic Mini, Mini 2 and Mavic Air 2.Just another follow-up video for the changes from v1.1.5 to v14 days ago ยท Good Afternoon/Morning, Having issues getting one of my batteries to charge which was in long term storage and won't turn on or accept any charge. Removed the casing and manually charged the battery to 11.8 volts ( 2 cells had no charge and one had 2.6 volts) and holding, all 3 cells are 3.9 .
