Works great and takes the hassle right out of topping off batteries.
Works perfect every time, fills my golf cart battery at the right levels without guessing
After inserting the filler into the battery water hole, press down to start the distilled water flow into the battery.
Fill them once every 60-90 days or the battery will stop working and when it rains you'll be up excrement creek without a paddle.
