JRC JHP500 handheld transceiver

I have been trying to find the operator's manual or other documentation
for this unit on the web, but have not succeeded. If anyone can direct
me to a spot on the web where I can download it, I would be grateful.
Thanks.

I have an owners manual. Contact me and I can arrange to get it to you.

I also have the same unit. Is there any reasonable way to replace the
original rechargable battery?

If it is a detachable battery pack, there are several suppliers that can
swap the old pack for a new. I replaced a NiCd pack for a NiMH on an
ICOM.

Where did you go? I'd love to try that.

I cannot remember which one. I checked prices at AirVenture and bought
the one with the best price. Look in any of the aviation mags, they
usually have ads. If you cannot find any there, I will look for my
business cards.

Lots of places re-cell battery packs.

The battery packs from my Cherokee handheld CB's fit my JHP-520. When
those are worn out, I have AA battery packs that I'll use with NiMH cells.
That seems to me like a much better idea than dedicated battery packs that
are difficult and/or expensive to fix -- individual cells are easily &
cheaply replaceable when they die, and they're interchangeable with GPS,
flashlights, etc.

Be careful when switching to alternate battery technologies. NiCads are
designed to be charged at rates up to 3C while most NiMH are
typically designed to be charged no faster than 1 to 1.2C. As a rule of
thumb, NiCads charge FAST while NiMH charge slow but have much
larger capacities. Another important distinction between the two battery
types, when peak charging, each battery type indicates "full" differently.
Long of the short, if you change battery technologies, make sure you
change chargers too! Otherwise, you may be in for a surprise including
very short battery life, batteries which never hold a full charge, and
maybe even fires.

All my NiMH chargers claim to be able to charge NiCD batteries too;
are they lying to me? Or are there big compromises? This is
completely intellectual curiosity, since haven't used any AA NiCD
batteries in years.
