6. CHARGING
When recharging a fully discharged battery, the starting charge rate may be 3 to 5 times
higher than the finish charge rate. The charge rate should taper down to the finish rate
by the time the battery is 85% charged and may be even lower when fully charged. High
“on charge” temperatures or frequent need for water additions are indications of
overcharging. Short running times and/or low end-of-charge specific gravities may
indicate inadequate recharge. Consult your local GNB Industrial Power representative
on specific charging problems.
The ampere-hour rating of the charger applied to the battery should be within 10% of the
ampere-hour rating of the battery.
7. CONNECTIONS
The battery cells are connected in series using welded lead connectors.
8. MAINTENANCE
KEEP RECORDS… Showing specific gravities, equalizing, charging, temperature, and
voltages on a monthly basis. These records are required to maintain your warranty.
TEMPERATURE… Under normal operating conditions, the electrolyte
temperature shall be between 60-100˚ F (15-37˚ C). Operating temperature
above 100˚ F will reduce the battery’s service life. Operating temperature below
60˚ F results in less capacity and special charging is required.
WATER ADDITIONS… Add water at the end of the charging period when the battery is
fully charged and the charger has tapered to its finish rate. See Item 9.
EQUALIZE… Once a week for heavy application (e.g., 80% daily discharge) to once a
month for light duty application (e.g., less than 50% daily discharge). If the Tubular-HP
battery is charged with a GNB
® EHF-series charger set for the Tubular-HP charge profile,
equalization should be performed every 12 weeks.
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 9.
