Ingersol Rand 20V batteries

[Pabird]

How could both of my 20V lithium batteries go bad at the exact same time? Let me explain. I have a 1/2" drive IR 20V impact wrench that has worked perfectly for several years. It has seen only very light use, never abused. Now all of a sudden both batteries throw the same code, 6 flashes of the red light = over current, high current detected, battery may be defective. WTH! What does this mean exactly and how could both batteries go bad at exactly the same time?

Probably the charger.

I thought the same at first but the charger goes through a specific sequence for both batteries.

Wonder if the batteries have a built-in expiration date, similar to what smoke alarms have. 7 years, and done.

I have two w7150 impact kits. No issues with any of the batteries

I read of Makita batteries that have discharged too far can have issues with the charger refusing to charge them so it might be a similar problem.

Did you ever let the battery go empty? Li-Ion batteries should be stored at above 50% of charge level.

An update on my battery issue. I e-mailed the IR help center and they replied that it was probably a bad charger. (Good call Skin)So I'll order one up and report back.

Visionguru, no never completely discharged either battery. Not even close.

Just an update to close this issue. I ordered and received a new charger and it charged both batteries.
