Connecting larger batteries with APC 1500va pro

[armada]

I got this apc 1500 (exact model BR1500GI) removed its internal dead 24v battery cartridge 9ah (its small) i am thinking to extend its wires and attached bigger batteries for longer back up... anyone expert here can guide will it support big batteries and what amps should i go for (this ups takes 2 12v as 24v battery)

Also if i attach for example two deep cycle 50ah batteries it will become 100ah so how much back up i would get out of fully charged batteries?

I think these UPS are not configured to support/charge larger batteries, so in order to make them compatible with larger batteries, it needs to bw tweaked.
You can take it to some reliable shop who deals in Apc ups, they can make ur ups to support larger batteries.

dear this ups is step sine wave and used solely with single or two work stations .. u cannot convert its charger is any possible way .. go for smart series if u want longer back ups .. this ups is like 3k in open market here in lahore ..
