SERVICING LEAD ACID BATTERIES WITH HYDROLINK®
WATERING SYSTEM
WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals
known to the State of California to cause cancer and reproductive harm, and during charging,
strong inorganic acid mists containing sulfuric acid are involved, a chemical known to the State
of California to cause cancer. Wash hands after handling. For more information go to www.
P65Warnings.ca.gov.
1. Position the container of distilled water below the level of the top of the batteries
to prevent siphoning.
2. Place the end of the watering system hose in the distilled water and squeeze the
bulb to ll the system.
3. Remove the dust cover from the Hydrolink® snake connected to the batteries.
4. Connect the coupler on the Hydrolink® snake to the coupler on the watering
system using the quick disconnect ttings.
5. While squeezing the hand pump, observe the ow indicator (spinning red balls).
As the batteries begin to ll, the spinning of the ow indicator balls will slow.
Batteries are full when the ow indicators completely stop spinning.
NOTE: Battery systems may take more than 1/2 gallon of water once the
BatteryShield® light has illuminated. Failure to actuate the hand pump until
the ow indicator stops spinning will result in batteries being under or
unevenly serviced which will reduce battery life.
6. When the ow indicator stops, and not before, immediately disconnect the
couplers by depressing the push button on the watering system coupler.
NOTE: Leaving the watering system connected could result in the batteries being
over lled. Disconnecting the watering system before the ow indicator stops
spinning will result in batteries being under serviced and battery life will be
reduced.
7. Replace the dust cover on the Hydrolink® snake.
