My pleasure. Sometimes what i see with battery watering systems is people stop filling once the green light comes on. That only means about 1 cell is full. The battery watering system will stop itself once all the cells are full and will never overfill if installed properly. It gives the impression that the battery is fully watered when the green blinky comes on when in reality it isn't, it stil, has about 16 more cells to fill. Best of luck!
