I don't know if it was to this group, or not, but I recently posted a remark
averring that all third-party lithium-ion batteries -- even from well-known
companies -- were junk, and a waste of money. (They are.)

I can't speak for nicad or NiMH battery packs, as I've never bought
third-party replacements. (OEM replacements have always been first-rate.)
But the prices companies want for replacements are often insane.

I've never seen a cordless phone with unwired ("loose") cells that could be
easily interchanged. Part of the reason might be legitimate safety concerns,
* but most of it is simple greed. It appears that manufacturers insist on
selling a battery pack they can profit from down the line.

You might consider tack-soldering the old leads to new cells. This can be
tricky, as you don't want to overheat the cells.

* I have a thin Sony Discman that takes two AA cells. There's nothing to
prevent you from recharging any AA cells you put in the unit, and I've
successfully recharged other brands.

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.

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