This battery is from my trusty old Phantom 4. It's been sitting for a little more than a year ( I have two other batteries in the same state). When I first checked it, it flashed 4 bars, then dropped to one bar. I plugged it in, and it won't take a charge...it's been in this state all afternoon...that is LED 1 rapid flashing for 18 flashes, then a pause, then more flashes. It's charging inside on the standard DJI charger. Battery isn't warm. Not swollen.
I don't have high hopes that these three are recoverable batteries, but before pitching them I thought I'd post to see if anyone has any insight.
