[Elecraft] Keeping the battery charged

[George, W5YR]

Bingo, Fran! It works for me, too.

I readjusted a small 4-amp, 13.8 volt supply to provide 14.4 volts at the
input connector of my K2. The PS runs 24/7 and even though the battery is
relatively old  - K2 Serial No. 489 - it remains in good condition and
appears to have full capacity.
