Hi Shay

well that's a good idea (didn't occur to me). This will save the house 
being filled with beeping noises, when I'm trying to sleep, until the new 
batteries arrive (as well as save me from swollen and leaking batteries).

I used to do this with disks, but they last so much longer now that I just 
leave them till they fail (and they aren't failing).

I've just put a note in the calendar on my phone.

I've never got more than 2.5 years from a set of batteries. They're at 
13.2V (I seem to remember) so they're not being charged hard. How to you 
get 5, 4 or even 3 years out of them? Is it the battery? (One of the 
Duracells leaked badly at 2.5yrs.)

Don't upgrade a working machine - it won't work any 
better - it could work worse; it may not work at all.
