I’ve used the drone maybe 20 times since buying it in March '17. The point being that the batteries have been charged about that many times and maybe less. I was told on this forum that if you charge the battery and say a day or two later, press the status button, it will reset the auto discharge clock to keep the battery fully charged. That sounded good but left me the other day with a problem…
I charged both batteries and a few days later went to fly my drone. One batter was showing only 2 or 3 LEDS, while the other showed all 4. This happened again. Thats when I learned of the auto discharge feature. I was then baffled by the difference between two I think identical batteries, treated the same careful and proper way.
I charged them both. One day later pressed the button. Checked. One day later and pressed the botton. On day 3, one of the batteries had lost a chunk of charge and the other was fine. I repeated this with both batteries disconnected from the drone in case one was getting charge leaked away that way. Nope. So, my question is this. Is one of them duff? It fells likely to me. I’ve applied any firmware updates that came my way. Should this be covered by the shops guarantee or do I need to battle with the DJI staff too?
