Hello Robin,
10,5 Volts is very low for a 12 V.lead-acid battery. Try to load it with
a lamp or resistor and measure the voltage at the battery again under
load condition. I doubt that all cells in the battery are good. The gel
in these batteries can dry out, which is killing them.
There is also a series diode in the supply-line to prevent damage due to
reverse connection of a power supply that at least has a voltage drop of
0,2 volts. I don't recall on what voltage the K2 will cease to work.

Hi,
I hope someone can help me here. I have K2 with the internal battery kit.
I have used this radio with the battery for many years, but now I have a
problem.
When I power up the radio with only the battery it is dead, no display nothing.
When I apply a PSU it works fine.
I have checked all the connections P3 (Aux) and the Int. Battery switch on the
back panel is ON.
Anyway, nothing has changed since it last worked.
When I check the voltage on the battery terminals it says 10.5V. I get the same
reading on the P3 connector, so power is reaching the radio, but the radio is
not powering up.
Any suggestions?
Thanks
Robin
