[Elecraft] K3 on 14.2V supply?

My K2/10 had its own power supply in a matching enclosure. Since it has the
internal battery (which incidentally, at around 8 years old, still seems OK)
I set the voltage to 14.2V to keep it charged up, as recommended by
Elecraft.

Due to the higher current demands of the K3/10, I got a Diamond power
supply. This can cope with running the K2 at the same time, which is good
because I don't have space for two power supplies. The output is variable,
with a detent at 13.8V. I could crank this up to 14.2V as well, to keep the
K2 charged up.

Now 14.2V is within the maximum 15V supply voltage stated in the K3 spec,
but still I thought I should run it by the experts for a view on whether
this voltage would cause any harm to it.
