The bog standard rechargeable batteries (750 mAhr) in our DECT phones are
starting to lose their ability to hold their charge: they indicate full
charge but the phone cuts out with "low battery" within a few minutes of
being taken off the charging base station, especially if used on
speakerphone.

Is there a problem with replacing them with batteries that can hold more
charge ie 750 mAhr. I presume the phone will still charge them at its
standard rate (though it may take longer to charge them).

I will go for branded (eg Duracell) rechargeable batteries.

I presume that if the original batteries are NiMH, I should go for that same
technology.

I believe it's because they are always on their pedestals being
(over) charged that the NiMH rechargeable batts die young. I've
just replaced another set in a cordless handset & am not leaving
it on the charging stand, only when it needs a charge...

Ours (Siemens c47) are always in their cradles when not being used but
the original Chinese NiMH batteries are still OK after nearly 9 years.
Maybe some phones have better charging control than others.
Same here. I've only changed ours once and that was after a similar time
period. I have however replaced one handset as the charger proved to be
faulty. Got a replacement 2nd hand on ebay from Holland.
