Phone battery question.

Can you use a Ni-MH battery in it? Will the in-built charging system  
suffice for a Ni-MH battery? I generally replace like for like in those  
circumstances and use NiCad to replace NiCad. That said, I had a triple  
set of those phones and it was cheaper to buy a new set of *phones* than  
bother with a set of 3 batteries. Yes, they were all on the way out.

Dunno, that's why I'm asking. Both are the same voltage but presumbly
later phones have smart chargers... or so I've been told.

Ni-MH.



About the same time again.



But that is a Li ion battery so quite different.

It predates Ni-MH but both are cuurently available as replacements.
It's the differences in the charging systems that concern but I'm
unsure as to whether it really matters.

Stick with what's known to work.

I failed to mention that the nicad is twice the price but there's also
a possibility they'll no longer be available further down the track.
Nor do I want the hassle of replacing the phone as the cradle is
screwed to the wall.

Consequently I've decided to stick with nicad and hope it lasts
another 15 years..

Thanks to all who replied.

Thanks for the washup, too rare imo.

Any NiCds you buy today are likely to be old stock - up to 10 years old.

Does that matter? My experience with rechargables (though I'm not
sure about NiCds in particular) has been that old but never-used
batteries have good performance similar to new.

SLAs may be an exception, my leaving those on a shelf doing nothing
for a few months has often turned out to be a death sentence. Very
annoying given how pricy they are.

He did say connector and since its an ancient cordless phone,
it isnt likely to be any of those.








Nope, thats what the previous batterys delivered.

Call pack. 2/3AA.



Yep, holes to plug but painting is the worst part.  The colours never
match and I certainly don't wish to repaint a room.



The previous two did.  :)



Dunno about that, Wes still list Japanese nicad cells (Sanyo or
Panasonic) although that may cease at any time in the future.

Not sure that age matters much either as they seem to last forever
until the first charge.

Which raises yet another.  Current model Sennheiser cordless
headphones use nicads as do the cordless headphones from Wes.  I
certainly don't want to throw the Sennheisers away. :(

** Absurd crap.  

 NiCds do not usually have a long shelf life.
They corrode and leak if allowed to go flat.
Just like Alkaline cells do.

Why don't the 10 year old ones leak?

  Cadmium is toxic and persistent in the environment.

 Even CdS photo cells are banned in the EU etc.

Bullshit they are and they clearly aren't banned here and that's what  
matters.




Irrelevant to what John should use.
