    check with the UPS manufacturer. You can't turn off the battery.

    You can rationalize it any way you like to make it work in the way you want it to work.

    Although UPS batteries stay energized, hard to imagine that if it was turned off in the right conditions and timeframe, that it would be more hazardous to turn off than if you worked on it hot.

    There are often other ways around working it hot, depending on what system or connections you are working on. Generally bypass' or temp connections get rid of the need to what was considered in the past was a reason to work hot.

    Are you talking about just battery replacement or beyond that?
