Options and Accessories
Battery Fill Indicator
The Baery Fill Indicator provides a quick visual indicaon of when one of the baery cells is low and needs water
added. It is installed in place of one of the baery ll caps. The wire lead goes to the baery negave terminal. When the
level is Okay, the green LED is lit.
Battery Watering Kit
The baery watering kit provides a convenient way to add water from a jug into all baery cells at once. Each baery has
a manifold that replaces the ll caps. The manifolds are connected with rubber hoses to one another and to a ll port.
A separate ller tool is connected to the ll port on one end and the other end goes into a container of dislled water.
Squeezing and releasing the bulb pumps the water into all of the baeries simultaneously. As each baery cell becomes
full, a shut o valve closes in its baery cap. Once all of the valves are closed, the pump bulb will feel hard since it can no
longer pump water.
