I have the SH HX230 and I think the packs are the same or similar. Yeah, the replacement pack from SH is expensive. Problem is, it is a well made pack and they've been keeping parts
for it on a shelf for over ten years--you're paying rent.
If you look on the web there are places that will rebuild
battery packs. I would have used one of those places but needed it turned around inside a week, so I did it myself. gotta warn you--that's not a job for the faint of heart, the construction is EXTREMELY tight in there and if you short out the new battery pack, it can and will start a fire. (Don't ask me why I know this to be true.)
The good news is, if someplace rebuilds it for you they can use Panasonic AA cells with a capacity 3x-4x higher than the factory packs. Still gonna cost you well north of $50. I say Panasonic because mine will hold a charge all winter long and still work well in the sprng, but the Chinese NiMh cells (originals were NiCd, you can use either to replace them) will lose their charge in 2-4 weeks, they're a waste of money
In theory NiMh and NiCd require different charging
and treatment. In practice, if you use the original charger
(which was an overnight charger) it will take over 24 hours to charge up new high capacity cells. 3x longer to charge, yes, but 3x longer run time, this is not a bad thing! And because the charging
time is so long, the charge is so gentle, you can ignore the NiMh/NiCd differences.
When I called SH the man actually apologized about the price
and the capacity (600mA was good 20 years ago, it's poor now) and he sent me the DC lighter cord for it for free. Hey, that was something he didn't have to do, I was impressed.
Still a great radio...but $100 for a battery pack...well...great radios aren't gonna cost that little today but some of the new radios do have a lot more features in a smaller package. And I suspect the new ones can't be used as sledgehammers--like these old ones.<G> SH made "commercial" grade equipment
back then, not consumer grade. The difference tells.
