    We installed a Pro-Fill on the coach batteries of our class C. Installation took only a few minutes. The system is easy and convenient to use - both plusses that will help you better maintain your batteries. Just a little quick pumping with the filler every month or so keeps the electrolyte at the proper level without overfilling. Make sure to get the filler device as well.

    I got this directly from Pro-Fill about 4 months ago - 2 sets for 4-6volt batteries. What a great product..!! Remember how messy and inconvenient filling batteries is with the hygrometer (or perhaps you don't use a hygrometer and do it by the old drip method from the water container). Remember overfililng and having the electrolyte boil-off during charging, creating a HUGE mess..??!!! NO MORE - with Pro-Fill, you just insert the pick-up tube into the Distilled Water container and pump until it doesn't pump any more. That's it.. DONE..

    I have had this system on my 5th wheel for over 2 years. I have 2 6 volt Interststes. They were hard to see and hard to fill to the proper level before I got this system. Now they are not over filled and can be filled with out even pullling the batteries out. It takes longer to set up the simple system than it does to fill the batteries. With 2-3 squirts on the bulb and it is done for another month. Total time to set up and fill is about 5 mins. or less. I sold my 5th last week, and that system helped me close the deal. So from now on I will not be without them on my next 5th and on my new golf cart which has 6 batteries.
