Flip Top Battery Watering Cap - Flow-Rite Controls


Flow-Rite is proud to announce the latest in battery watering: Water Wise, the first ever flip top battery watering cap. Water Wise allows for the peace of mind denied by standard battery watering gun and cell cap technology. The patent pending design limits an automatic watering gun’s nozzle depth without the aid of an O-ring or mechanical stop that requires tools to adjust.  This allows for reliable electrolyte levels every time and prohibits interference with the battery’s moss shield. Just push in the cap for an easy installation.
Water Wise is durable enough to withstand demanding industrial applications.  The low-profile caps sit well below the inter-cell connectors for less chance of being accidently dislodged. Time and training are saved by not estimating the O-ring/stop position for every watering cycle. Even if the O-ring/stop is properly adjusted, it can be moved out of place after watering many cells.
