ups + extra battery? (alien.top)

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?

As others have said, buy a bigger ups. You can then take your old one and move some of you other gear to it, which make the new one run your server for longer. Ideally something with auto shutdown software.

This is what I ended up doing. I am on my third ups now, and my oldest one is now protecting my desktop.
