I bought a iMac recently and I love it.
Interestingly though, the batteries that came with the portable mouse have already started to die and I keep getting warnings on my screen telling me to change or recharge them as soon as possible. Diligently, I took the pair of wasting AAs out of the mouse and located two fresh ones from the drawer.
They didn't work.
I took two more out. And they didn't work either. I tried further combinations of the ten or so AA batteries in my drawer, all of which I knew to be at full pelt, and the mouse wouldn't have them. So I put the original batteries back in and they worked, albeit the warnings about their diminishing power returned.
A quick scan at some Apple forums suggest that this is not uncommon.
So, does this mean that the mouse for Apple has been designed only to use not just a specific size of battery, but a specific brand too? That sounds like a tie-in, and not a great one if, as these seem to be, the brand happens to be one that you don't recognise from the battery displays you see behind every shop counter and beside every supermarket conveyor belt.
These work, and are in the mouse at the moment:-
These, despite being very similar (and far more familiar, to me at least), do not:-
The difference is in the word 'advanced'. And another brand of AAs called ActivEnergy don't work either. The forums claim even good old Duracells fail to work too.
I just thought battery size was all you needed to get right. I'm clearly wrong.
Anyway, a mate suggested I buy these for future use, and I have duly ordered some. They'll at least work in the various remote controls about the house if they're not good enough for an iMac mouse.
