A single 3/4" press in watering system battery cap with water level monitor.

  • The quick, simple, and safe way to maintain your deep cycle batteries.
  • Easy to see water level indicators. 
  • Allows for the watering of batteries without having to remove the caps.
  • Built in ceramic filter that acts as fume arrestor.
  • Anti-splash to protect against acid spills.
  • Fits batteries with a round 3/4" press in hole.
  • Most 12 volt deep cycle Marine & RV Group 24,27,29, & 31 batteries
  • WILL NOT FIT BATTERIES WITH TWIST LOCK CAPS! PLEASE CHECK Your Existing CAPS and MEASURE!
  • These caps require 2 1/4" of clearance above the battery mounting surface.
  • Works great with our squeeze bulb, squeeze bottle, or 1 gallon Ez battery filler.

 

Quick and easy installation:

1. Remove your old battery cap.

2. Fill your battery to the manufacturer recommended level with distilled water.

3. Install your Ez-Check battery cap.

4. Adjust the O-ring to just below the red float indicator.

5. Now when the red indicator dips below the O-ring you know it's time to water your battery.

6. Remove the rubber cap on the nipple of the battery cap and fill slowly until the red indicator rises back above the O-ring.

7. Install the rubber cap and continue to monitor at regular intervals.

    Single-Press cap can be used to check and add fluid in NAPA 8231 that has screw-on caps by sitting the single-press cap on the battery top above the cell.

    On our 2019 Winnebago Forza the 4 batteries have to be removed to check the fluid levels and add fluid as needed.
    The Press-On cap has a gauge shaft length long enough to measure the fluid level by placing the cap over the cell and add liquid as necessary so the battery cells can be checked with out removing the batteries.
