APC UPS battery replacement - alternatives

[supersunbird]

UPS setting almost all will switch off at about 2 hours no matter the battery size or remaining amp hours.
I have come across 1 or 2 models that don't

Luckily my Eatons don't do that. Maybe because they have active cooling fans?

Correct. After 2 hours, and the UPS powers off, i just manually switch it on and off and the UPS gives me another 2 hours. The Blue Nova batteries are amazing.
