The flip top plug (part# MB000) has a large opening for easy inspection and filling of batteries.
This plug does not automatically water the battery. Each cell must still be individually watered.
However, the plug locks in place on the vent well using a quarter turn of the plug.
Once the plug is locked in place, it is much easier to fill the battery compared to standard vent openings on batteries.
When using the flip top plug, batteries can be easily watered using the BFS manual watering gun.
The flip top plug gives easy access to test the electrolyte level with the hydrometer.
The flip top plug fits on all quarter turn vent openings in batteries.
