Keep getting BAT Err message

Bob G3PJT
When I try to charge the battery I get Bat err message and charging is
terminated. I have reloaded s/ware etc but no change.
Any ideas ?
Thanks
Bob G3PJT

Bob,

Read the BAT ERR description on page 4 of the KXBC3 manual.

You may have to remove the batteries and check the terminal voltage of
each one with your DMM to determine if you have a bad one, or if all are
possibly fully charged.

Reloading software will not make any difference, but likely will not
hurt anything either.

I'd swap out the batteries and then go through the procedure that Don
recommends.

Dumb question; they are all NiMH, right?  Hopefully Eneloop or a similar
marque?

Thanks very helpful. I just found the problem it was that the batteries were quite discharged and my charger PSU was a touch low in voltage. Seems OK now.

Re:  "...batteries were quite discharged..."

Bob,

Glad you got things working.

Keep in mind that if any cell was discharged below 1 volt, there is a likely chance that it has been damaged and cannot be recharged successfully.  That is why the KX3 shuts down at 8 volts, to protect the cells (1V per cell X 8 cells = 8V).  That is also why it is important to use Low Self Discharge (LSD) cells.  Non-LSD cells will continue to self-discharge below that 1V level, destroying themselves.

Just retested all the batteries individually to check they are still OK
after charging and they seem fine.

Thanks for all the help
