    Having had a spicy car battery myself last weekend, due to inexistent voltage regulation, I would have expected that one to be able to vent the excess pressure. Sealed battery out not, it’s better not to build up pressure

      Do SLAs usually have vents?

      Car batteries, even maintenance-free ones, do…but I can’t recall seeing them on smaller SLAs like your find in a UPS or PowerWheels.
