Well it's done 10 years on the original batteries, so can't complain;
but I want to get some replacments as they are definitely stuffed.

First port of call was the manufacturer's website, where I find this
in the FAQ for my shaver (at http://tinyurl.com/pcflz8h):

"Q. Can I replace the built-in battery with any type of rechargeable
battery available on the market?

A. No, definitely not. You should on no account replace the built-in
rechargeable battery with any type of rechargeable battery you can
buy in the shops. The built-in battery is tailor-made for the
charging system in this shaver. Do not try to replace the battery
yourself."

Hmm.

So - Google then directs me to Allbatteries
(http://tinyurl.com/pyl794h) where I find exactly the battery I need,
along with the statement: "This battery has been manufactured with
high quality components. It conforms with the exact specification of
the original manufacturer and the battery is guaranteed against all
manufacturing defects." (It certainly looks like my battery; but the
original has no relevant markings to compare it with).

Do we think it's safe to assume that the manufacturer's FAQ is just
revenue-protecting, arse-covering ********, or is there any genuine
reason why I shouldn't just go ahead and order the new battery?

Thanks for the all the reassuring replies: I'll go ahead with the plan
then!

The battery pack is 2 AA NiCd batteries. I assume the charger is of
the trickle type so I can't think of any reason why it's not safe.

Yes, it's the manufacturer's original; a 9W wall-wart.

Personally I wouldn't bat an eyelid and get the replacement. Whether
you can get it cheaper elsewhere is perhaps another question. It
depends on how you value your time.

The link above was the only place I could actually find a bespoke battery
for my old shaver; however if everyone reckons this is nothing more than
a couple of standard tagged AA NiCds I can look further afield. Of
interest is that at, say, http://tinyurl.com/p3qlk5g I can buy
appropriate 1.2V cells of a range of mAh ratings - 600, 1300, 1800, 2200.
Now, I don't know for sure what the current ones are as there are no
markings, but the dual-cell replacements I found at
http://tinyurl.com/pyl794h were rated 2.4V/700mAh. Does that mean 350mAh
per 1.2V cell, or what? Is this an issue? Assuming these replacements are
correct, do I need to replace with identically-rated batteries, or can I
just go as high as I want to maximise time between charges?

Thanks
David



350 and 700 seems very small. I've used 1800 and higher...
