i have APC ups cs650, it holds my server for 10-15min. Is it possible to hook up an extra battery to prolong runtime? I am thinking to hook up car battery, 12v 50-80Ah. would that work? any issues I may face?

Don’t use car battery in UPS. They are made to start car, high surge current. Under deep cycle in UPS, battery will be ruined in a dozen cycles. Get a 12v 50-100ah LFP (LiFePO4) battery. Wire it to UPS. Should do the job. I retrofitted multiple UPSes with quality LFP. Much better
