Quoted message said:Long ago I reported that my bottom-of-the-line handlebar-
mounted eTrex ran 10 hours on NiMH batteries (from
CCrane); that slowly wandered down to 6 hours as they
were recharged over and over, so I replaced them with
new 2200mAh PowerX AA's. These run 15-16 hours on the
first charge anyway (in my two eTrex's, the older one
ran 15:15 and the newer
16:00). It may get better before it gets worse, since
the first charge just sort of limbers up the
batteries.
The interesting thing is that that's longer most
alkalines do.
You need a better charger. I have two sets of 1800 mah
NiMH batteries that have been in service, nearly daily,
for two years. I use a Maha C204F charger; it has a
reconditioning cycle that I run on each battery pair every
2-3 weeks. No noticable decrease at all in battery life in
the Vista.

I used that and the later C401FS (an even better charger - I
charge also 8 AAA's every day so have a charger armada
available) but I think the CCrane batteries are much less
than 1800mAh, probably 1400 or so, and running at zero
degrees F in the winter has not done them any good.
The reconditioning is for NiCads. The NiMH don't have a
memory effect; and the reconditioning amounts only to
discharging them, and mine are discharged for practical
purposes (when the voltage drops, there's very little left).
I think now that reconditioning has been debunked even for
NiCads. Anyway the newer charger doesn't have it any longer,
yet is for NiCads too.
