You can use 12V 9AH VRLA battery - they are the exact physical dimension. A better option: extend the power supply cables so you can connect to an external 100AH ~ 200AH VRLA battery so you can have 24 hours power backup availability during a power blackout.
You need to know what the power draw is in total. 260 watts power draw will give you just over 5 minutes to safely shut down. Here’s a link to the product page where you can enter your power draw and it will tell you how long you should get: www.apc.com/uk/en/product/SC420I/apc-smartups-sc-420va-230v/
