[Elecraft] [K2] KBT2 Battery

[thom2 at att.net]

  Don knows from the K2 battery, he has a very informative article on his web site about the care and feeding of SLA's.

  I also believe that if you are charging the K2 through the power jack in the back of the rig you are running through a voltage reversal diode before you get to the battery, which is dropping the voltage about .4 volts or so and that's probably accounting for the difference.
