A single 12 volt 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 arrestors.
  • Anti-splash to protect against acid spills.
  • Fits most 12 volt 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 caps.

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

3. Install the watering system caps and note the position of the red float indicators in reference to the green line.

4. When the red float indicators drop, remove the rubber cap, and add distilled water slowly to bring the fluid level up.

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

    Single-Press 12 Volt 3/4" Round Press in Watering System Battery Cap with Water Level Monitor

    Great system. Have 6 for the RV chassis battery and 18 of the twist lock for each of the cells on the house batteries. This save so much time and effort as the water level on some of the cells cannot be seen without using a flashlight and mirror. I've never been able to get the liquid in all the cells at a consistent level. What a great idea and product! Thank you.

    Not for NAPA 8231 batteries

    Posted by Leo Suarez on Aug 7th 2020

    I bought this water level monitor to check the water on my NAPA 8231 batteries on my diesel pusher which are very difficult to see water level without removing them. They do not fit the battery as a permanent install as advertised. There is no EZbattery level monitor that you can install on 8321’s. But the valve will fit through the battery hole such that you can insert it, hole by hole and see if there is enough water. Too bad it is a great system and idea but not as a permanent solution for NAPA 8231’s.

    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.
