Nice analysis. For Eneloop Pro batteries, with 2550 mAh capacity,
that would be 21% of capacity for the clock plus 15% for self-discharge.
Of course, whenever the KX3 is connected to “shore power”, that is
used instead of the battery.

I opened my KX3 and measured the current draw on my internal Eneloop

You’re supposed to replace the smoke detectors every 10 years because they lose
sensitivity. In my experience, 9v alkalines in the AC powered models last
nearly that long. I assume it’s just the shelf life of the battery.

One risk is that their discharge curve is higher and flatter than alkaline

The most likely answer is that your batteries are self discharging.

Good morning, I was wondering if Elecraft was thinking/ thought of implementing
( if possible) a trickle charge addition to the KXBC3 module for the KX3 rig?
I know this has been brought up in the past was not sure if it was address or
soon to be?

The recommended 13.8V minimum is for the external supply, and does take
into account the diode drop.

Hi,
I believe your PS reading is too low. The PS reading on the KX3 should be at
least 13.8 volts. There is a polarity diode so your ext power supply should
be 14+ volts.
At least this what my KX3 needs to cha
Good evening all. I believe I solved the problem I had put the rig on charge
(so I thought) last night for 16 hours. Once I turned the rig off the LCD
just went to it's normal black screen. After posting my question I wanted to
try a 4 hour charge and once the rig was shut off the display light up
You should have greater than 10.0 volts after a full charge I would check
the batteries individuallyyou may have one or more bad batteries

16h * 200mA = 3200 mAh. That's not enough to fully charge 2850 mAh

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

Good to hear such stories. Charging NiMH is not easy.
I bought 4.8Ah Li-Ion battery for $57. Weighs 10 oz. Six weeks ago charged
from 4A 4 oz computer charger in 1.5 h. Traveled to OH, ES and PA and made
many contacts from each country. Came back and made many more contacts. 12W
all the time. Bat
