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

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.
