Battery? V70-XC70

Something else to think about when selecting battery (besides price) is hydrogen gas venting. As a safety feature to prevent H2 gas explosion in the spare tire compartment, Volvo has a hydrogen gas vent tube that carries H2 gas outside the vehicle.

Interstate and others sell a "sealed" battery with no vent port. However, these batteries have an internal pressure relief valve, and if conditions build up pressure in battery to 2-3 psi, this valve will dump hydrogen gas into the spare tire compartment. Any spark will ignite an explosion.

My mother lost hearing in one ear from a car battery hydrogen explosion. There is no warning.
