Contact size is part of an SLA battery's specs. Small contacts are terminal type
"F1". I've never encountered a UPS that uses them. All I've encountered use
terminal type "F2", which is 1/4" or about 6.35mm wide spade.

It's a big planet. Where is your "here"?

OEM batteries must hold up through warranties, so are probably more locally
sourced for high quality rather than low cost from China. Less expensive UPS
models might be designed for a shorter expected lifetime, overcharging more as
they get older and heat takes its toll. It's not something very many consumers are
equipped to test.
