Description
This battery vent cap provides peace of mind since it has a flame arrestor. Due to the fact that all lead-acid batteries produce flammable gas, a flame arrestor is an important option. Hence if a nearby spark ignites the gas, the spark arrestor stops the flame from entering the battery where it could ignite the internal gas. You can learn more about this battery vent cap by reading this article on battery flame arrestors.
