Is it all right to replace a 12v 4.5ah battery with a 12v 4ah battery in UPS?

I'll answer my own question since no one answered it. I replaced the 2 pcs. 12v 4.5ah battery w/ 2pcs. 12v 4ah battery. It seems alright since it is now working fine for at least 2 months w/ 1 PC connected to the UPS. What I'm concerned though is that the UPS will overcharge the batteries since the replacements have a lower ah rating.

The charging will be fine - it is how long the UPS will run for (if you mains cuts out) that has been affected by your replacement.
