Railroad Battery Watering Gun

The Railroad Battery Watering Gun is specifically designed for watering diesel starter batteries and solving the problems of watering these batteries.  Manual watering of diesel starter batteries is ineffective, inconsistent and incomplete because cells at the back of the battery are hard to reach and therefore seldom watered.  Additionally, manual watering is slow; it takes at least 30 minutes per locomotive!

The Railroad Battery Watering Gun employs a unique, ergonomic design that allows the operator access to every cell on the battery.   It is also fast; the battery is completely watered in about 10 minutes!  And the Railroad Watering Gun features precise automatic shut-off; every cell is filled to the optimal level.  This battery watering gun allows diesel starter batteries to be watered safely, completely and cost-effectively.
