Maintenance Cleaning, Water Additions

•WATER ADDITIONS… GNB-approved fast chargers have the capability for equalize charging at specific times and days of the week (eg. Sunday 08:00). Water additions can be made the following day prior to use, provided an equalization charge is confirmed to have been performed.

•EQUALIZE… Once a week.

•DEPTH OF DISCHARGE… Do not discharge the battery below 80% of the rated capacity. Over discharging shortens the battery life and voids the warranty.

•CLEANING… Keep the top of the battery clean and dry. See Item 8.

•PREVENTIVE MAINTENANCE SCHEDULE… WEEKLY

•Check electrolyte levels (see water additions).

•Equalize charge.

MONTHLY

•Record electrolyte specific gravities.

•Visual inspection and confirmation that the battery-mounted monitor is functioning properly.

•Inspect the cables and charging plugs.

•Clean the top of the cells.

SEMI-ANNUAL

•Inspect the charger. Confirm proper output voltage and current. Check for external damage, frayed cables, or worn connectors.

•Clean the exterior of the battery.

TROUBLE SIGNS

•Battery temperat ure averages more than 125˚F (52˚C).

•Open circuit cell voltages vary by 0.15 volts or more and specific gravity varies by 0.020 or more during equalizing.

•The top of the battery is always wet or one cell requires excessive water.

8.MAINTENANCE CLEANING

The top of the battery should be kept clean and dry. Keep the vent caps in place during use and charging. Remove them 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 servicing representative. The solution used to clean and neutralize the outside of the batteries should be disposed of in an environmentally safe manner.

9. WATER ADDITIONS

Maintain electrolyte levels above the bottom of the perforated, plastic element protector, but no higher than 1/8" from the bottom of the cell cover vent well. Check the electrolyte level weekly, or as necessary depending on battery use prior to charging. If the level is not visible (below the element protector) add just enough water to cover it 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 between 1.2-2.2” 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 representative if you are not sure of your water quality.

BATTERIES MUST BE VISUALLY INSPECTED

PER THE ABOVE SCHEDULE EVEN WITH THE

USE OF A WATERING SYSTEM.
