I recently came across 25 Enersys 12HX205 DataSafe batteries that are in good condition and were previously used in a UPS. I'm considering using them for my off-grid RV solar system. What are the pros and cons of doing this?

One thing to note is that these batteries aren't designed for frequent cycling, based on their warranty info. With the right battery management, you might get better lifespan and performance, but just be cautious about not discharging them too quickly or below 50%. Just keep in mind you’ll need to figure out what to do with around 1075 pounds of scrap lead in a few years!
The biggest downside is definitely the weight and eventual disposal. After 5 years, you'll be stuck with a hefty amount of lead to deal with, so factor that into your decision.
Just a heads up, lead-acid, gel, and AGM batteries usually have a lifespan of 5 to 7 years if you treat them well. They can drop below 5 years if not cared for properly. Also, don't discharge them below 50% of their capacity to avoid damage. Do you know how old these batteries actually are?
These Enersys batteries have features like individual flame-arresting cell vents, so they seem safe with proper handling. Just remember they're lead-acid, so avoid any enclosed settings where hydrogen might accumulate. Safety first!
Haha, love that term! Definitely keeping it in mind!
