Cordless Phone batteries are all junk?

Update, I did find it at Uniden for $25 apiece, plus shipping.

This fact really does not change my question.

We get our NMH AA cells from Batteryjunction.com. Have not heard of a bad one. I don't know if they have the battery you specify, or not. Then, again, you may have to but them by the case.

Not familiar with that particular battery configuration, but you can often make up your own battery pack with the right cells. Try:

recently made up a replacement pack for my Roomba, at a 3rd of the cost of the OEM pack, using sub-C NimH w/tab batteries. JR Dweller in the cellar

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.

Ive had EXCELLENT luck with these people

"I am for doing good to the poor, but I differ in opinion of the means. I think the best way of doing good to the poor, is not making them easy in poverty, but leading or driving them out of it. In my youth I travelled much, and I observed in different countries, that the more public provisions were made for the poor the less they provided for themselves, and of course became poorer. And, on the contrary, the less was done for them, the more they did for themselves, and became richer." -- Benjamin Franklin, /The Encouragement of Idleness/, 1766

Not meeting your expectations for longevity is not dishonest if they honor their stated warranty. Lowest price isn't always best value. You're just not as good at finding bargains in new consumer electronics as you are with gov't surplus machine tools and such.

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:

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.

Me too. I've had the Panasonic on my desk for 5 -6 years & it came from the dump, so who knows how many years before I got it. Bob

On the other hand, I replaced the batteries in 2 Motorola cordless phones with batteries I bought on Ebay from China for 2/$1.00 + $3 shipping. They hold a charge noticeably longer than the OEM which worked just fine. I guess I just got lucky.

I got a local Batteries Plus, and if you take your old battery pack in there, chances are pretty good that he can make you one just like it out of components, and the prices are darn good. I have a Uniden police scanner, and getting a battery pack made was half the price they wanted, even online.

He also ignores the fact that the phones may have problems that are damaging the batteries. K-mart sells replacements for that battery pack for about $7. the problem is, how long have any of the replacement packs been sitting on the shelf?

All I want, is a battery pack that would last me 4 years. You have a good point that perhaps the chargers are damaging batteries. My understanding of this is that the chargers are programmed to charge only one type of battery (such as Ni-MH), whereas replacements are of another type and that ruins them quicker than necessary.

Do you mean cordless phone or cellphone, they are two different animals in how they use power?

JR, I've got a dead Rhoomba, and would sure like some details on that.
