[Elecraft] [KX3] [KXBC3] Fresh Charge Depleted

[Ron D'Eau Claire]

You didn't charge them long enough Gary. 

Battery voltage is not a good indicator of the state of charge. 

You indicated that they were discharged and that they are 2400 mAH
batteries. As the manual says, Charging Time = 1.2X(MAH rating)/200. So your
batteries needed 14.4 hours to charge up. Set your charger for 16 hours.
(see "Determining the Charging Time" in your manual)

I just installed the KXBC3 in my KX3 SN 460. The batteries are Sanyo Eneloop
XX 2400 mAH rechargeable NiMH batteries. I had charged them one time before
installing on a NiMH specific charger. There was maybe a few hours of use on
them. They were run down to the point where the rig shut down. As soon as I
installed them in the KXBC3, I did a 4 hour charge to top them off. They
indicated a full charge when I was done. I turned on the
KX3 and the battery indicator showed a full charge but began an immediate
slow discharge. Within a few minutes they hit the 8.5 V limit and the rig
shut down. I've read and re-read the manual but do not see anything that
I've done wrong. I've been running the KX3 on SLA batteries with no issues.

Suggestions, Please!
