[Elecraft] KXBC3 charging

[Mike Weir]

Good afternoon all, I installed the KXBC3 in my KX3 last night and it had no error messages or problems.....up until now.
Here is what I did and what is happening.
1. Batteries that are installed are Ansmann 2850 MaH  NiMH brand new min charge on them if any. 
2. Put time on KX3 for 16 hours of charge time and left the Astron power supply for full 16 hours.
3. In the morning after charge time tried to turn KX3 on with just battery power. It would not and found out needed to lower min voltage from 10v to 8.5v. 
4. After doing this the rig came on and was fine on battery power. 
5. Took rig to the park this morning and it failed to start again. Double checked at home to make sure the new min volt setting saved and it did. I then moved the min 
setting to the lowest value which was 8.2 volts.
6. On the display I am getting the following now PS. 13.6 volts (not sure way that as voltage on my Fluke meter at the Jack before it goes into the KX3 reads 13.8v)
    BT is reading 8.8v but is is fluctuating from 8.1v to 8.8v at times.
Now even with an internal battery reading of 8.8 or a little less the rig should still turn on?? The only other thing I can think if is the 2850 MaH batteries need more than 16 hours of charge time?
