I bought a whole bunch of batteries from someone that crashed their drone. All of them were fully depleted and wouldn't register any leds at all so I got them for a good deal. although I did bring along a micro usb charging cable to verify they would take a charge.
The good news is I managed to charge all of them up normally and they seem to work fine
Bad news is I noticed on one of them the release tabs were slow to move and not very 'springy' making it difficult to release from the quad. Well i decided to spray some lubricant on it. Big mistake, for some reason it had the opposite effect! It seemed to harden on the battery like superglue. Now the pull tabs barely move at all and require even more force. Not sure what can be done, needless to say do not try this!
