Rechargeable Battery Advice

paulofessex

Good evening, looking for some advice regarding the difference between rechargeable batteries, in particular AAA's

I need batteries for a landline cordless phone. On looking at AAA's what is confusng me is the MAH so far l have found 800 MAH 750 MAH and 2450 MAH the list goes on.

Do l take it that the higher the MAH the longer the batteries will last, bearing in mind their for a phone.

Also is it better to buy the better known makes i.e. Duracell

Many thanks

I use this make and have done for years with no problems (Price inc P&P). I would be very interested though in 2450 MAH AAA batteries,
what make are they?

2450MAH? I'd have some of those - you'd be able to heat the house with them!

Can you ?

- AA's not AAA's @ 2450mAh

- triple A's rechargeable, that do that number I'm interested in, so include me with espresso

We have also been using 7 day shop rechargeable batteries for years.

2450 mAh is well over twice the claimed capacity I've seen in AAA, even expensive single use lithiums are rated to about half that.

But yes the higher the rating the better in general. Some applications benefit from low self discharge batteries. Probably not a phone that is on a cradle all of the time, but things that are lower drain or infrequently used, e.g a remote control, you would be better using the low self discharge type. Basically Ni-Mh batteries start losing power as soon as they are removed from the charger. Charge them up and put them in a draw for a few months and they will lose most of their charge, even though you haven't used them.

For a few extra ££s try to get the new tech type, they charge on conventional nimh system so if old bats were nimh tnen this new type will charge fine:

reason - they last longer, perform better and seem to resist being very warm all the time like when permanently charging in a phone holder.

I got some cheap batteries at play.com last week some AAA batteries. I also have the Sanyo eneloop ones as mentioned above
