About Battery Vent Caps
Battery vent caps from PowRparts let industrial and lead-acid batteries release gas safely while keeping electrolyte in. Shop standard and flame-arrested quarter-turn caps, flip-top caps, push-in caps, and Water Miser caps.
What Are Battery Vent Caps?
A battery vent cap covers each cell opening. It allows hydrogen and oxygen produced during charging to escape while preventing debris from getting in and electrolyte from spilling out.
Benefits of Battery Vent Caps
Missing or damaged caps let contaminants into cells and allow acid spray. Flame-arrested designs add protection against external sparks igniting battery gas.
