Spicy Dell Tablet Battery
(lemm.ee)
Dell tablet we recently removed from service at work due to going spicy...4 years on the charger. The tablet was mounted to the wall and used as a punch clock. More pictures: https://imgur.com/a/w8PKSKP
Probably ought to toss it back on the charger. Just to top it off.
Dell replaced a ~3yr old battery in my 9575 because it was over 60% worn with moderate use and mostly plugged in. The new battery was almost half as thin. Can't wait until this one is ready to explode.
