Since its generally heat that destroys SLA batteries in a UPS, then
putting a couple of cheap (even second hand) 7ah alarm batteries in
parallel outside the case is an option. Find an alarm/security
tech/contractor and see what they have changed out due to age rather than
state of charge. Probably pick up a boot full for scrap!

For fitting inside, the nearest I came up with was 9ah from tastech.co.nz
@ $39inc.

Depends on what uptime you're looking for and on how accurate the float
charge mechanism for the batteries is.
