[Elecraft] K2 Internal Battery Voltage

[RICHARD SCHNEIDER]

Insight needed. I noticed my K2's internal battery voltage dropped to below
operating range even though the rig was in charging mode while plugged into
mains. I assumed the battery had gone bad. Pulled the rig apart and measured
voltage while the rig was off. 12.1 VDC. Turned the rig on and measured
across the battery. 8.9 VDC. Any ideas where the problem lies?
