I wanted to charge 3 pieces TB 48 and one pieceTB 47 on the loading hub. The batteries had already 7 to 18 charging cycles. The charging LEDs on the hub showed one by one permanent green. Unfortunately I could not fly the next day and therefor I left the batteries on the charger.
After about 10 days I have removed the batteries and had to realize that they were completely dead. No function was existing even though the charger showed constant 4 green LEDs.
Hoping to recover the batteries I had the lid of the batteries dismantled and as in Forum recommended the plug under the lid for a while pulled. This could only achieve that the battery LED 1 once, then LED 4 blink twice per second continuously. No additional function was possible. The batteries could not be used anymore.
DJI replaced the batteries instantly but without any comment- my question why the error or defect occurred remained unanswered.
Has anyone had a similar experience or an explanation for this? Must the batteries be removed immediately after charging - or when latest?
meanwhile I keep a close eye while charging on the batteries and try to remove them as soon they are charged.
Thanks
