After 15 or so years the nicad battery in our 30y.o. portable phone
has chucked it in (it\'s only ever had one replacement). The current
options are nicad or Ni-MH.

Which way should I go?

If Ni-MH how long is it likely to last?

I only get around 4 years between replacements with a Samsung mobile
which presumably has a smart charger, hence the question.



**If the \'phone was designed to use NiCad batteries, then that is what
you should use. NiCad and NiMh batteries have different charging
requirements.

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.


If it predates NiMH, then it\'s unlikely to be designed to charge them
properly.

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.

but there\'s also
a possibility they\'ll no longer be available further down the track.

Nope, thats what the previous batterys delivered.

Call pack. 2/3AA.

but there\'s also
a possibility they\'ll no longer be available further down the track.

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?

I have seen may items destroyed by leaking NiCds, including some of my own.


FYI I do electronics repair for a living.

He clearly knows that his previous ones didn\'t.

Irrelevant to whether better designed ones don\'t.

In fact you are a dole bludger.

Go like for like. It will probably outlast the phone.
