Exide Technologies GB4146 - Manual (Page 5)

TROUBLE SIGNS
Battery temperature averages more than 125°F.
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 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.
9. WATER ADDITIONS
Maintain electrolyte levels above the top of the separators, but no higher than 1/8" from
the bottom of the 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 top of the
separators), 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 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 Industrial Power representative if you are not sure of your water
quality.
