erroct Posted September 1, 2019 Report Share Posted September 1, 2019 I keep getting a check battery error: my battery is an Aspire 21700 4000 mah but on the wrap, it says its an inr 21700 Li-ion battery. I think I let the cell get too hot/discharged and is acting weird? I can't figure it out. It's not a very old cell. Sometimes the vape will hit as shown.
