I usually get the 12V22AH batteries instead of the 12v18AH APC spec.
The dimensions on those have always been the same, so I question if
there's actually a difference of if it's just fancy calculations. I
don't bother to do any adjustment of the UPS for the small AH change. I
only change the external battery number if I'm putting 100AH batteries
on it. The actual runtime will be governed by the LVD. If you hit the
LVD, then you're probably using the wrong batteries anyway.
I've just been going to Ebay recently for all my small batteries, Seems
to be 1/3 the cost of batteries plus.

I've regularly done 12v 9ah from batteries plus instead of the 12v
8ah. I get a few extra minutes and it's worth the dollar or two. I
think we pay $22 per 12v 9ah.

So for my small UPS's I've always just gotten equivalent Volt/AH
batteries and they fit in. I had a SmartUPS1000 that used 2
12V12AH
batteries. I bought a new set of 12V12AH batteries, and they
are about
1/8" taller than the old batteries and wouldn't fit in without
modifying
the case. I always just thought there was some 'standard'
where all
batteries of the same V/AH are the same physical dimensions.
Is that
not the case? I've never had a problem getting 12V18ah-22AH
batteries
to fit in other UPSs, as long as the studs on top are
positioned correctly.
