The battery which came with the battery kit from Elecraft about 12 months or
so ago is refusing to take any charge- I think I left it too long sitting at
a nominal 13.8V and it never properly charged after having been discharged.
I shan't repeat the mistake and will modify the K2 to take a separate
I agree Stephen! I only bought the KBT2-X (that's the kit w/o the
battery) and used a 2.3 AH battery as that was the largest capacity I
could find in the UK that would fit (Yuasa from memory, although I am
now on my 2nd battery and can't recall the typle).

Hi Dave
There are some Yuasa batteries on eBay at the moment specified as deep
cycle, but I agree that most of these batteries are only designed for
standby use and in most applications will only ever sit on float charge
throughout their working life.
I was just hoping for one with greater capaci

Hello Guy
Yes, I had the same issue and that's what killed the battery for me. By the
time I had realised and had increased my psu output voltage to 14.5V,
unfortunately the damage had been done. Don W3FPR has some info on his
website and has provided a separate charging input socket for his K2
Well of course it's a question of convenience. It's neater and more
compact to have the battery inside the K2. Also a major advantage of
the battery for me is that it weights the K2 down on the desktop so it
doesn't slide away when I push a button. However the main use it has
had is when I forgot t
I think several suppliers do suitable batteries. It is important they don't
