Depends on how you stored them and how long. You need to make sure that they were at least 50% discharged when you put them away. Don't trust them to self discharge, that's how I lost several batteries. They were supposed to discharge themselves to storage level after 10 days, but never did so they ended up puffing on me. As for how long, since getting an Inspire 2, we no longer use the Phantom. However since we don't want the batteries to go bad just in case we need it for something, I've set up calendar alerts on a 3 month interval reminding me to cycle the Phantom batteries every 3 months to keep them from discharging too much.
Thanks, that is new info to me. With lead batteries, you have to keep them full, so I put these away full expecting them to hold a charge through the winter and I would charge them next time I used them. I knew Lithium is supposed to hold a charge much longer so wasn't really worried about it, but I have also never had a battery pack on any other device do this. This leads me to wonder if there is a fault in the DJI charge / discharge controller circuitry logic. |
