TROUBLE SIGNS…
The battery temperature rises more than 25 °F (14 °C) during a normal charge.
The cell open circuit voltages vary by 0.15 volts or more and cell specific gravities vary by 0.020 or
more after equalizing.
The top of the battery is always wet or one cell requires excessive watering.
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 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 if you are not sure of your water quality.
The GOLD and PLATINUM options for Tubular-LMX™ Low Maintenance batteries are equipped with
an electrolyte level sensor and a single point watering system.
BATTERIES MUST BE VISUALLY INSPECTED PER THE ABOVE SCHEDULE
EVEN WITH THE USE OF A WATERING SYSTEM.
