Looking to replace the batteries in my cordless phones. Checked eBay and buddy has a "replacement" for my phone model. However, the ones he's selling are NiMH whereas the ones that came with the phone are NiCd. When I asked the seller about compatibility, he said to "check with your manufacturer" (thanks!). So can someone shed some light on this for me? Are NiMH batteries charged differently than NiCd batteries should I be able to use the NiMH ones instead of the NiCd ones?

No problem to replace NiCad batteries with NiMH. They are about the same voltage (1.2v), and the existing charger should work just fine with them.

Sorry to stray O/T a bit here, but when I was in Zellers yesterday, all of the phones were using nickel cadium batteries [that is, the ones in the $30 - $50 range.] Even a Uniden model had been returned [gee, I wonder why] as it had a nickel cadium. I didn't know one could replace the batteries with NiMh ones. Good to know. I hope more people write, to back this up. ;)

I had to open up the boxes and check the battery out, as it listed it no where! {I asked the sales clerk if that was o.k.}

I've replaced the NiCd batteries with NiMH for quite a few phones and they all work just fine. And they last substantially longer.

Of course, not all phones are 'mod'able ... The OEM AA NiCd batteries are actually a bit shorter than the retail NiMH AA batteries. You may need a bit creativity ;)

For those phones that use small NiCd battery pack, you may need to use AAA batteries as substitutes.

I bought a direct replacement NimH battery pack on eBay for my two Panasonic phones to replace the original NiCad batteries which were crap. Works great!!!

I also replaced the NiCad battery in my Philips shaver when it went and that made a huge difference in time between charges because I actually stuffed two AA NimH cells in to replace the single NiCad which had gone. This was a lot messier though since some soldering and dremel work was required.
