Water Miser Battery Vent Cap FAQs
What are the advantages of using them?
Their primary function is to prevent water evaporation from batteries, maintain electrolyte levels, and reduce maintenance frequency.
Do they fit on car batteries?
No. Car battery vent caps are usually the push-in or screw-in type. Water Miser Vent Caps are the ¼-turn bayonet mounting type, and therefore will not fit on automotive batteries unless an adapter is used.
How do they work?
They use an internal mechanism to collect and condense water vapor, allowing it to return to the battery, thereby reducing water loss.
What batteries are they used on?
They are commonly used in industrial, renewable energy, and heavy-duty applications where battery reliability is critical. Some examples are electric golf carts, and other deep cycle batteries.
How do I install them?
Simply remove the existing vent caps on your battery and replace them with Water Miser Caps. Tighten them by hand only until snug.
How do I know if the caps are working properly?
Reduced water loss and less acid fume buildup around the battery are indicators that the caps are functioning correctly.
How much water loss do they prevent?
They can significantly reduce water loss by up to 30%, depending on usage and environmental conditions.
Do they reduce battery acid fumes?
Yes. They help trap and condense acid fumes, improving safety in the surrounding environment.
Can using these caps extend battery life?
Yes. By maintaining proper electrolyte levels, they can help extend the overall life of the battery.
Should they be removed or loosened during charging?
No. They must remain tightened, otherwise that would bypass the function of the flame arrestor, resulting in a possible battery explosion.
Water Miser Benefits
Saves Money
- WATER MISER battery caps reduce water loss by up to 30%. In this regard, the moist vapor enters a chamber where the liquid is trapped and then returned to the battery cell. In addition, the vapors pass through a special porous disk which further slows moisture loss.
- Less battery maintenance time. No need to remove the vent caps from the battery. Just flip open the top to see the fluid level or add more water.
- Add water less often because of reduced water loss. Also, this miserly cap quickly pays for itself by saving time and labor costs.
- The top of the battery stays drier, reducing voltage loss due to the current being conducted across a wet surface.
“Green” for the Environment
- Water Misers reduce fumes and airborne debris, resulting in cleaner air to breathe. Also, battery makers use them in their charging areas to reduce fumes. Therefore, most sulfuric acid fumes that could flow into the air are trapped inside the battery.
Water Miser Safety
- Water Miser battery caps have a spark arrestor that lets the gas escape but stops any sparks or flames from entering the battery cells.
- Reduces repetitive motion fatigue. The twisting motion that is needed to remove the cap from the battery is done away with. The flip-top cap also provides easy access.
- Less exposure to fumes and sulfuric acid. No more handling of acid-soaked vent caps.
User-Friendly
- The Water Misers’ flip-top cap can be rotated to any desired angle. This lets it fit where space is tight due to battery cables, terminals, or terminal covers.
- The internal splash guard stops splashed drops when filling the battery. As a result, this keeps the top of the battery drier and the liquid in the cell where it belongs.
- Our model #2000 Water Miser battery cap fits all battery watering guns with a nozzle diameter of up to 3/4″ (#2000C & #2000CE up to 7/8″).
- The standard bayonet mount fits most forklifts, golf carts, and floor scrubber batteries.
Do water miser battery caps really work? You can find out what others who have used them say by reading their comments in this private forum. They are happy with them since they are now watering their batteries less often.
