Actually, "sealed" batteries are not as sealed as you think.

They still have vents, and still create explosive gases when charging. If they weren't vented, they would explode. They can also still leak acid from these vents if tipped over. They usually have some sort of valving in the lid of the battery that makes them lose less than a regular battery though.

The dumb thing is that they're more expensive than non "sealed" batteries, but you can't top them up with water when they get low. I'm pretty convinved at this point that they're a scam.

Also, deeply discharging a car battery will damage it and shorten it's life span.

What you really want for this application is a deep-cycle / leisure battery. Car batteries are designed to deliver huge amounts of current for short durations. Leisure and deep cycle batteries are designed for more constant (but lower current) power draw and can better handle being deeply discharged.

With that said; if this is what you've got, use it! :)

I hope you and your loved ones stay safe, and that Ukraine is victorious against the invaders sooner rather than later.

Slava Ukraini!
