SWOLLEN BATTERIES

[360 Guy]

I noticed that two out of three batteries were getting hard to insert and withdraw from the drone.
The swelling occurred in the middle of both batteries.
Pictured battery on left with NO swelling as opposed to the bulging battery on the right.
I drew a yellow line straight up the side of the battery to show the swelling for reference.
Both pics are the same except for the vertical yellow line to show swelling.
The other swollen battery was not pictured as both swollen areas are the same.
I rotate my batteries so all batteries have equal flights numbers.

Batteries were approx. 4 years old with 67 flights,
Time for new batteries a must.

Yep. Time to replace with fresh batteries.

Yup. Time to stop using those swollen batteries. They are done, fini, over, cooked, dangerous, bad for your drone's health, etc.

Thanks for sharing your experience and the pictures.

Your post prompted me to research safe disposal of lithium drone batteries. It is important to discharge the battery completely before disposal.

Best Buy and Lowes accept old batteries.

It's most likely the age of the battery, rather than the number of cycles. Most retired their Mini 2 units a long time ago, although I still have mine, too!

same thing happened with my router battery.

was having prob, and tech told me to remove battery

when I did. It swelled like a balloon.

had to duct tape the cover on while I waited for new battery.

Reminds me of the Norwegian Blue skit from Monty Python:
