Tech Tips: A Nifty Battery Water Filler

Get a charge out of this nifty battery water filler.

The placement of batteries in some motorhomes can make them difficult to service. I found an easy, fool-proof tool that works for any battery, regardless of location.

Purchase a one-gallon or smaller garden pump sprayer. Remove the wand attachment, leaving the hose and trigger assembly. Add distilled water to the sprayer’s tank, pump a few times to add air pressure and squirt the water into each battery cell with no mess or overfill.

    Possibly even better, saw off part of the wand for a bit of “reach.”

    Don’t pump too much, or the spray could splash back some acid from the battery on you!!
