Tom,
If you can adjust your power supply to 14.0 volts, it should work a little
better. I bought my K2 battery with the K2 in 1999 (S/N 462), and it still
is as good as new. I also bought a Power Sonic 0.5 amp automatic charger,
and it floats the battery all the time. It charges the battery at a
constant current until 14.4 volts is reached, then maintains a constant
voltage until the battery is charged as sensed by the current decreasing to
a small value, then floats the battery at about 13.8 volts. My perception
is that if the battery is not topped off at 14.4 volts it never is fully
charged, but it may reach full charge if floated at 13.8 volts
constantly. It just takes longer to reach full charge.

Hi all,
I have a basic K2 (s/n 1103) without the 100 amp. I also have the
Elecraft internal battery (KBT2), which I use in the field. At home the
K2 is connected to a 13 volt power supply which, of course, charges the
battery while I'm operating.
Unfortunately life will be getting in the way of operating over the
next several months and I was wondering if I should be concerned about
causing any permanent damage to the K2 battery while it is not getting
charged. I'd appreciate any thoughts on this.
I will be around and can turn on the PS to charge the battery from time
to time (how long and how often?), necessary.
Thanks
