9. MAINTENANCE CLEANING
The top of the battery should be kept clean and dry. Keep the vent caps in place during use and
charging. Remove the vent cap only to observe electrolyte levels, make water additions, take
temperatures, or take specific gravity readings with a hydrometer. If the battery requires cleaning,
contact your local GNB Industrial Power servicing representative. The solution used to clean and
neutralize the outside of the batteries should be disposed of in an environmentally safe manner.
10. WATER ADDITIONS
Maintain electrolyte levels above the plate separators, but no higher than 1/8" from the bottom of the
vent well. Check the electrolyte level quarterly, or as necessary depending on battery use prior to
charging. If the level is not visible (below the plate separators), add just enough water to cover them
and then proceed with charging the battery. Otherwise, defer watering the battery until the end of the
charging period when the battery is fully charged and the charger has tapered to its finish rate. At that
time, add enough water to bring the electrolyte level to 1.2” of the top of the cover. Always use distilled
water or water that is known to be free of abnormally high amounts of impurities. Contact your local
GNB Industrial Power representative if you are not sure of your water quality.
Before watering
• Make sure that the battery is disconnected from all charging equipment.
• Make sure that the battery is properly cleaned.
• Make sure that you are working with safety glasses.
BATTERIES MUST BE VISUALLY INSPECTED PER
THE ABOVE SCHEDULE EVEN WITH THE USE OF A
WATERING SYSTEM.
WATER ONLY AFTER CHARGING.
