Depends on the type of sealed battery. My preference is for a sealled
gas recombination based one, with gas vent - they don't explode at
all, don't even leak fluid. Used to run them all day long in a big
plastic greenhouse, lit by some 40KW of lighting, inside an old WW2
building, with the outside temp in the 110's - not a single
roble,.Course, at $300-ish a shot for a reletively small 30Ah one,
they're not cheap, but worth it - especially since they'll do about
2000A peak output, and will take the same input as charge.
