We have a very fancy Uniden CLX-485 phone system. While it worked
great for 2+ years, the batteries lost their ability to charge.

My attempt to buy "generic oem batteries" ended up with garbage
batteries that will not hold charge.

My first question is WTF. Is it really so difficult to make a good
rechargeable battery?

My second question is, is anyone aware of an honest seller of
batteries?

Were the batteries the same size and technology as the origionals? Were they
wired with the same polarity as the origional? When/how did they "not hold a
chargs"? Did you ever consider buying the proper replacemant battery?

Same size, likely inferior technology and materials. Dishonest CHinese
manufacturers and importers.

Replacement batteries from Uniden cost $2 apiece. For six phones, the
cost is $32, pretty much the same as a new phone system. If I cannot
find sensible batteries, I would like to buy a phone system that takes
AA or AAA batteries. These made great strides lately.

Presumably a supplier with a US retail presence like Batteries Plus will
have a bit better quality control since they have a reputation to
maintain.

And yes, it is that difficult to make a good rechargeable battery, that
is why pretty much no rechargeable battery powered device has a long
enough run time per charge, be it a cordless phone, laptop or EV. If it
was easy we'd be driving electric 1 ton pickups with 750 peak HP and 500
mile ranges.

Possibly. Apparently Exide makes the Werker brand.

A new battery for my cell phone would cost more in Radio Shack than
another phone, so I checked it in Batteries Plus. It was almost as
expensive there. The 2 year old phone battery is fine, actually.

I recently treated myself to a laptop for my birthday, a $0 Compaq
from 1999 with almost an hour of capacity still left on probably the
original Li-ion battery. 500 MHz and Win2000 is enough for most
applications.

I reformatted it FAT32 and rigged it to dual-boot Win2000 or the DOS
from Win98SE, which gives QBasic full unhindered access to the
parallel port for hardware tinkering. I've already logged the on and
off times for my electric water heater with it.

Before you Unix 'shippers chime in, the datalogging voltmeter has only
DOS and Win display software, although I wrote a faster driver in QB.
