3S battery not reading on S155 charger

[Schism]

I have used this charger to charge this battery countless times, however probably hasn’t been charged since October. When I go to plug it in, the charger just shows a battery with a question mark. Is the battery so dead it isn’t being detected? Do I just need to leave it plugged in a bit and it’ll end up reading it?

A 3S battery reading at 2.3V is toast. And it is also a potential fire hazard.

Batteries Plus stores and some hardware stores will properly dispose of lipo batteries.

Well that is a shame. I should have charged it up after the last run and not let it sit, which is my bad.

Thanks!
