Some of the older Siemens 2.4-gig cordless phones take a pair of
standard AA NiCd or NiMH button-end cells. I don't know if that's
still true of their current models.

You might want to consider sending your existing battery packs to a
reputable battery rebuilder... they can often open the case without
destroying it, and replace the cells inside.

Hard to tell from the picture... are these just AA cells
in a "custom" holder? I have had panasonic "battery packs"
of similar design and was able to disassemble the "holder"
(if you look carefully, you can see where the top "keeper"
is a separate piece that snaps on -- though yours may be solvent
welded) and replace the cells.

Any particular model number Uniden phone system?

How many years? My various Panasonic cordless phones seem to last
about 8-10 years. I'm on the original batteries for all of them.

What didn't work well? Did the battery run down too quickly? Did you
have inadequate capacity (time running on battery)? Did it fail to
take a charge? Any measurements or numbers?

Yep. 99% of everything is junk.

That's quite possible. I've received some fairly disgusting cell
phone batteries that I would suspect are defective. The eBay vendor
exchanged them at his expense. However, you're right that such low
end stuff is usually not economical to return. If you want cheap,
then be prepared to take some risks. If you want a warranty, be
prepared to pay for it.

A quick Google search shows many vendors that sell this battery:
<http://www.google.com/products?hl=en&source=hp&q=uniden%20bt-0003>
at reasonable prices. I've also rebuilt these battery packs. Tear it
apart and weld some AAA NiMH rechargeable batteries in their place.
This is not brain surgery.

Yep. Quality deteriorates until buyers start to complain. It then
sits forever just above the complaint threshold.

Probably, but I don't know of any offhand. There seems to be a
tradition (or conspiracy) that every handset product, including cell
phones, must have a non-standard or weird shaped battery. Inside,
they're all basically the same batteries, but manufacturers go through
extreme efforts to prevent interchangeability. It wasn't always that
way as I still recall the old 46/49Mhz phones, that used common AA
NiCd batteries. Something changed, probably product liability
litigation, which forced the manufacturers to change.

Buy quality replacement cells from DigiKey and rebuild the batteries
yourself.

My experience has been that original batteries shipped with the devices are
good - often lasting 10 years or more - but that replacements don't hold up.

I've purchased replacement cordless phone batteries at Radio Shack which
only lasted about a year.

I have a Black & Decker cordless screwdriver. The original battery packaged
with the unit has much greater capacity than the free one I had a coupon for
and had to mail in.

I think they use the lower mAh "rejects" for the freebies.
