Rechargable Batteries

[maverick]

Can anyone recommend a decent continuously rechargeable AAA battery please?

It's for a set of home phones (master and 2 slaves).

I've tried a few different brands so far and most don't seem to hold the charge for very long once the phone is off the charger.


Many thanks

I used to use rechargeable in my home phones, never lasted that long. Gave up and just use non rechargeable , far more successful . Worth a try I suggest .

Panasonic Eneloops (Formerly known as Sanyo Eneloop), the white ones, 750mah is fine for phone handets.
Been around for years, nothing better out there.
Watch were you buy maverick, Fakes/Clones are all over the place, and how much you pay.
Sometimes the pricing is wierd, 2 is dearer than 4 in some outlets.

Here is a link

Just to supply another reputable vendor for you,

7 day shop in the channel islands..but they must be awaiting stock

"Eneloopies" have 70% of their capacity remaining after 10 years, beat that energizer, duracell and the rest, they hit the recycle bin after 2-3 yrs.



I said formerly known as Sanyo Eneloop, Yes arch enemies Sanyo and Panasonic have amalgamated and put aside their differences and re-branded themselves as Sanyo-Panasonic..I never thought that would happen..ever.
Those in the leckytronics game will know...Historically, even up to a few years ago they werent exactly the best of friends to put it very very mildly, but thats another story !

Hi Maverick

Please ignore the rubbish I stated above, brain storm or whatever I did use non rechargeable in something but having checked my phones it was not them!!!!!!!!!

In our phones therefore they are rechargeable AAA believe it or not from Morrisons (own brand) they have lasted very well as I cannot recollect when I started using them!!.

Hope this now makes more sense

Noted thanks..

Mr Amazon is delivering some enveloops as per radiostationx's recommendation Saturday; but thanks.

Fit and forget for 6-7 years at least maverick, probably 10 +
Your envelope of eneloops wont let you down in the middle of a PPI/"have you had an accident ?"/bank account long distance call direct from Mumbai or Manilla or Lagos for that matter...They will keep you connected.
That may be a good or bad thing depending on your point of view.
The larger Double A Eneloops were, and still are, unwritten the industry standard worldwide for press photographers Canon and Nikon flashguns, which are high current drain devices.
If batteries failed on a togger from AP or similar, try explaining to the picture editor you used the drumming rabbit cos he looks cute, that would be a bad day at the office and some.
Worry not Mr Maverick..Your phone handsets will have no issues with treble A 750ah loop the loops.

Having received some excellent advice previously, may I ask another question re rechargeable batteries please..

I've just 'found' a drawer full of rechargeable batteries AA and AAA taken out of various toys and things years ago.
Should I charge these up and expect them to work as previously. Or, because of their period of inactivity (I'm guessing up to 10 years) are these knackered now?


Many thanks

3-5yrs/1000 cycles is the limit for ni-cads maverick.
They may charge up sort of okay but wont last very long,if at all when put in a device/appliance and some demand put on them.

Years ago there used to be a 2R10 battery known as a ever ready number 8, zinc chloride "technology" back then..used in radios and other household things. They used to go on for years and years 10-15 typically..not rechargeable though.

Run of the mill Ni-Cads lose a lot of capacity over time, especially if not charged for long periods.

You can get away with phones as they are trickle charged permanently and in this situation its not strange to see 5+ year old nicads still working..but they have probably leaked all over the place inside the compartment or the phone lasts 2 mins off the stand.

Strangely,Eneloop nicads from sanyo/panasonic can be perfectly fine after a quick few hrs charging even if they havent been used for a few years.
They have the industry secret to making these things last. Totally different in every way to any other nicad cell on the planet.

Info much appreciated - thanks

Found this article on the following website called vintage-radio.net subject titled Summer fades, leaking dry cells, their forum members experience of leaking dry cell batteries by well known manufacturers, some of their findings are quite an eye opener !
As a matter of interest do lithum ion and Ni MH batteries leak for any reason ?
