I had to do an emergency replacement last weekend. The bad

12vdc, 4 amp hour gell cell

All I could find locally was:

12vdc, 5 amp hour gell cell


The batteries are identical except for the amp hour ratings.

I don't *think* moving up an amp hour should be a problem with this
type of battery. Am I right?

Not a problem as such, but you need to ensure that the replacement(s)
are suitable for UPS duty and not just GP types.
