Does anybody know

Well, I don't know if they are the best,
but they sure seem better, and less
expensive, in the long run, than any non-
rechargable batteries, I have ever used.
In other words, I have been very pleased
with the NiMH rechargable batteres. They
seem to last longer on one charge than a
non-rechargable Alkaline Battery.
Several years ago, I was displeased with
NiCD rechargeable batteries, but it seems
they now have it right, with at least NiMH
2000mAh rechargeable batteries.
Some NiMH batteries can recharge in 15
minutes. I started out using them for
Digital cameras, now I use them for almost
everything. They last until I lose them so
far.
I hope this helps, and if someone else
knows better battery solutions they will
repsond.
Good question.

For real cold. Though expensive Lithiums
will go colder than others.

regular batteries typically work mine have
lasted 2 years. I would check distance
between base and sensor, could be too far or
thre is interference.

I found that NiMH batteries tend to sit at
about 1.3V whereas a nice, new alkaline sits
at 1.6V. The strength of the transmitted
signal seems proportional to the available
voltage. My transceiver cannot hear a 2.6V
(two cells) powered motion sensor, but can
hear it when it has 3.2V.

I got a 36 pack AA energizers at home dept
for $12....

Yepper! No need to get fancy with the NiMH
or NiCd. The simple throwaway alkalines have
a higher standing voltage, lower cost, and
better yet a longer shelf life. I find that
the rechargeable cells tend to self-
discharge much faster than the low current
draw of the sensor I installed them in. The
rechargeable cell is completely dead within
a few weeks even sitting on a shelf (but
rechargeable) whereas the throwaway alkaline
is good for 6 months so far. "Tony" can get
2 years out of them.

Hey, has anyone thought about solor battery
chargers? Boy, this would be great for a
power source. Please respond if you have
heard of them being used with this
application.
