Water Injector Systems™

The world's fastest battery watering system!

The Water Injector System™ is the world’s fastest and most reliable way to add water to industrial batteries. Filling a battery takes just 15 seconds, which means that you can fill 8 batteries in the time that it takes to fill 1 battery with other systems! There are two versions of the system available to meet your needs: the Water Injector Classic System™ and the Water Injector Spider System™. Both systems feature legendary reliability and speed of fill but differ in the way that the water is delivered to each Injector valve and the way they fit on top of the battery.  

The system saves money in two ways. First, it cuts labor costs, often paying for itself within its first year of operation. Second, it extends the life of each expensive battery onto which it is installed due to improved quality of watering.

The system also improves safety and environmental cleanliness. There is no need to peer into cells to inspect levels as with manual filling. And water Injectors automatically fill each cell to the correct level, so there is no overfilling and no electrolyte spillage during charging.  Did you know that each time a battery boils over it loses 3% of its capacity?   That equates to 15 minutes of run time for each and every boil over!  And the only way to recover the capacity is to perform an expensive acid equalization process, which typically costs more than the Water Injector System.

Because of its robustness and reliability the Water Injector System is the preferred system for all Opportunity and Fast/Rapid charge applications.
