A flooded battery under the bed? Shoot! Might as well make more room and jam the stove in there too.
Flooded batteries without being sealed SEALED in an airtight box and properly vented through a 1-1/2" tube to the exterior do not belong under a bed. Period.
Terminals, wire and hold down parts do not corrode to nothingness because they are being kissed with love. Hydrogen, Hydrogen Sulfide, and various sulfur and acids accumulate while charging. If she has spent a lot of time in that rig I "vigorously" recommended she get her blood tested for Pb, LEAD.
This is a perfect example of when where how and why a sealed AGM battery MUST be used. Choose a group 29-30-31 for added capacity, then verify that no charging source exceeds 14.4 volts, and preferably defaults to 13.2. This means solar panel charging too.
Stupid stupid STUPID manufacturer. If children were to sleep on that bed, I would bet 100 to 1 they would be suffering from lead poisoning.
All of the above changes for the better IF the battery is already enclosed meaning SEALED in a properly vented box.
