Description

This battery vent cap is designed differently and costs slightly more than our standard vent cap, but it provides peace of mind. Due to the fact that all lead-acid batteries produce a flammable gas, a flame arrestor is an important option. Hence if a nearby spark ignites the gas, the internal spark arrestor stops the flame from entering the battery where it could ignite the internal gas.
