Bought the above and it came with two rechargeable AAA batteries for the handset. These NiMH batteries are rated at 550mAH and so does anyone know whether any other capacity batteries can be used i.e. 750 or 1000mAH? Is the charging circuit only matched to the supplied battery capacity?

Hi HHGTTG and welcome
Yes you can use 750 or 1000mAH batteries
mAH = milli amp hour
So in your case, a fully charged 500mAH battery would last for 1 hour if the device being used was using 500 milli amps.
If the same device was powered by 1000mAH batteries, it would last twice as long between charges.
The higher the rating (mAH), the longer it will last.
(hope that makes sense)
