Opinions or Information about this UPS? Tripp Lite SMART2200RM2U

I have the opportunity to pick up this Tripp Lite SMART2200RM2U locally from a seller on Facebook Marketplace, and it will come with the mounting hardware (rails & ears), for $100. This will be used in the racked Homelab that I am building up. The problem is, this UPS seems relatively old, which I know I will likely have to replace the batteries at some point soon, but it still seems like a good deal for a pure sine wave, decently large capacity “enterprise”ish UPS for the price he is asking for it. What I am unsure of is how well this older UPS will match with the modern day equipment I plan on running through it, and since it is a few generations behind if I will run into any major inefficiency problems or compatibility issues managing it through a NUT server or something similar. I can’t find any information on this specific model UPS since when you look up the model number, all you can find is the current generation refresh information and manual.

Does anyone have any information or experience with this UPS, or have any advise on whether it is a good idea to purchase this model, or spend x2-x3 more on a new, modern day UPS from CyberPower/EATON/Tripp Lite? The alternative that I have been looking at is the CyberPower CP1500PFCRM2U ( https://a.co/d/c8PdQ51 ), but at $335 it is over 3x the price as this older used model. I’ve also found it used for ~$270, but I truly don’t know if it is worth the extra price just because it is new and modern.

I really don’t want to pull the trigger on something that is potentially so outdated that it will give me problems down the line, but I also don’t want to overspend for no reason on a new unit when I can easily get this one and replace the batteries, if it will work fine for me. Any information or advice at all will be greatly appreciated!
