How do I remove old battery

Please find a 5 year child. They are good at getting into most things and should be able to handle the job for you.

Are these reliable batteries for use in smoke alarms?

Sometimes you've got to trust something ! I bought a box, have 3 smoke alarms, test them monthly, and change them annually. No problems - but I've never had a battery fail over the cycle.

Can anyone please tell me the exact dimensions of this battery?

It's a standard PP3 battery, the dimensions are the exact same as for any PP3 battery

What is the mah rating for these cells? Nice to know what you're actually buying.
