Several replies suggested I check the voltage of the NiMH batteries as a first step. Did so this morning, with an interesting result. Of the eight (all are 2700 mAh Powerex NiMH 1.2 v nominal), the mean voltage was less than a half volt (0.45 VDC); the median and mode were each less than one

Ted, The battery voltage was too low to start charging without possible damage. Yes, NiMH batteries will self-discharge to the point of not being able to recover them. Keep them charged, or you can loose them. The KX3 internal charger requires a certain minimum voltage before it can start

Re:  "Could the batteries have died from having been ignored for so long?" Although I have never experienced this with quality Low Self Discharge (LSD) NiMH cells, it may have happened.  I have experienced this with non-LSD NiMH cells, and they just aren't worth the time and effort to use. I

My KX3 has been sitting idle for many months. Turned it on today and tried to charge the battery, which I am guessing is depleted to zero, but I keep getting "Bat Err." Yes, there is a rechargeable battery installed - it has worked just fine for years. And yes, I did RTFM, about accessing
