[Elecraft] KX3 Grounding & NiMH Batteries

[Mark, KE6BB]

Re: "...is there one type of NiMH batteries to consider that might be considered the best?"

The term "the best" is always a difficult one for engineers, but I still have a three year old set of Panasonic 2000mah low self discharge  (LSD) cells in my KX3, and they are still working great.  The chemistry in these is identical to the Sanyo Eneloop cells, which are available in at least 2500mah LSD cells now.  Panasonic  ended up buying Sanyo, but maintained and continued to improve the Eneloop line.

One caution with any rechargeable cells is don't discharge them below their minimum discharge voltage, which is about 1 volt per cell for NIMH cells.  The KX3 battery warning and shutoff will protect them nicely.

Don't even consider cells that are not LSD cells.  Those will self discharge to a voltage below their minimum discharge voltage, destroying themselves in the process.
