installing extra power supply for 8132i

["Scott_DC" <scott.dc@xxxxxxxxx>]

I'm installing a 8132i keypad for my vista 128FBP system, and have a
question about the supplemental power supply for it. I orderd the
8132ipk so it cames with the AD12612 power supply/charger. The
documentation for the power supply says to use a 4AH Gel Cell battery.
Would I be asking for trouble if I used a 7.2AH battery? I'd rather use
the 7.2 because it's the same battery model i'm using for backup power
on the main panel, and I would prefer have a longer backup time.

Also, I need to get an enclosure to put the charger & battery into. Is
that something that I can pick up at my local electrical supply house?
If not does anyone have a suggestion of where I should order one
online?

Thanks in advance,

Scott
