WATER-MISER-CAP Solar Series Water Saving Vents for 6V & 2V Batteries

These devices reduce battery watering intervals and maintenance by about 50% as they help contain the acid and gassing while self hydrating the batteries. The “flip-top” opening simplifies watering. Use one Water Miser to replace each individual cap found on most North American made flooded batteries with a quarter-turn bayonet cap design.
