[Elecraft] K2 with internal battery?

I have a K2 with the internal battery option. There are a few of points to consider:

1. The basic "original" K2 draws about half the current of a K2 with the DSP and SSB modules fitted (mine is drawing 360 mA at the moment). While you can configure the K2 to draw less current, you are losing some of the nicer features and performance.

2. A K2 with the internal battery is heavy. The power to weight ratio of a lead acid gel cell isn't very good, a handful of NiMh AA cells have a higher mA hour rating.

3. A lead acid battery will suffer loss of capacity if deeply discharged, so don't expect to fully utilise the charge in the internal battery very often!

I'm on my second battery in 6 years, but not sure I will fit another. I've not had any leakage but tend not to use the K2 on it's internal batteries.
