you are misunderstanding the old school ways of setting charge modes and profiles for lead acid batteries. the charge mode and float mode are legacy methods associated with iron core transformers and liner voltage regulators when you needed to physically switch between current levels and voltage levels.
modern chargers current charge up to a taper voltage level then switch to constance voltage mode which is typically 13.5-13.8v. anyway I am sure your understanding is lost in semantic nuances. it's not your fault but I want to help people in the thread understand how it works enough to have the right perceptions.
I won't get into the chemistry but when you put an SLA cell above about 14 ish volts you start to dissociate hydrogen in the electrolyte. That is gas. You may have noticed flooded batts are vented and SLA batteries have pressure release valves built in for this reason to prevent bad things

Don't tell me to stop. I'm just correcting you erroneous statements I'm not trying to pick on you. I think you are just extrapolating wrong statements from some simple misunderstandings of the electronics and battery systems
Trust an EE PhD as hard as that might be.
have a great day. and happy to direct you to good articles if interested.
The charger in a UPS is designed for SLA will cut off charging when the battery reaches 12.46v and shut off the UPS when the battery drops close to 11.59v. That means the LiFePO will never be full charged or discharged. So in that sense it's safe to use in a UPS.
However because it will keep the battery to SLA specs, you'll only be using approximately 23% of the battery's capacity. So that 10ah LiFePO will behave more like a 2.25ah SLA battery in the UPS.

More to my point, can it run my trolling motor that has a max. draw of 52A ?
I have a new 12v 18ah that I bought for a fish finder, and then I hurt my back.
What else could I use it for?

to clarify, do you think connecting an UPS leads (removing existing SLA batery) to a LiFePo4 battery like this would basically work? Let's say 100AH rated capacity. Effectively this would function as an UPS with say 80% of the rated capacity ?
The 100Ah one should be $159 again on 8/3 so would like to buy it for UPS use.
