Hello

I own 4 generation 1 Segway’s. 2 of them for over 12 years. Over the last 5 months 7 of the 8 batteries have failed. They are all Lithium.

Nothing has changed. They are in a heated garage. None of my other electronic devises have failed. Only thing I can think of is the power went out before the first 4 batteries went bad. The others have failed over the last few months. I did not have them on a surge protector but after the first 4 went bad I added that but have had another 3 go bad since then.
Of the first 4 that have been repaired, 2 needed the BMS reset, 1 needed the BMS reset and reconditioned and the fourth had to be replaced.
I notice that a couple of the cords do not bite very well when inserted, could that be some of the trouble?
Has anyone had similar trouble or any ideas what the problem could be?

Thanks

Mike
