EXPLOSION - can result from the gases produced by a battery.
HANDLING - Injury may occur from the improper handling of batteries.
ELECTRIC SHOCK - cells connected in series have HIGH VOLTAGES that could produce a human shock hazard.
BURNS - Under normal operating conditions VRLA batteries virtually eliminate acid misting and acid leakage. However, one should be aware that burns can be caused by sulfuric acid contained within the batteries.
WARNING: DO NOT CONNECT ANY “TAPS” TO INTERMEDIATE POINTS ON THE BATTERY.
ANY DEVICE CONNECTED TO INTERMEDIATE POINTS WILL OVERWORK ONE SECTION OF THE BATTERY AND CAUSE OVER-CHARGING OF THE REMAINING SECTION.
