1. Guidelines for Your Charging Regimen
(a) During quick charges always charge battery to a minimum of 80% of capacity.
(b) Never allow battery to become discharged below 20% of capacity.
(c) Charge to 100% of capacity whenever possible. Put the battery on an extended or
"equalize" charge weekly.
(d) Check electrolyte level and strength before and after the weekly equalizing charge.
WARNING: WHEN CHARGING YOUR VEHICLE, USE ONLY A
FACTORY-AUTHORIZED CHARGING SYSTEM DESIGNED FOR A
72/80 VDC BATTERY. NEVER ATTEMPT TO USE A STANDARD
AUTOMOTIVE TYPE 12 VOLT CHARGER.
WARNING: THE PROCESS OF CHARGING LEAD/ACID BATTERIES
CAUSES THE RELEASE OF FLAMMABLE HYDROGEN GAS!
CHARGE BATTERIES ONLY IN WELL-VENTILATED AREAS.
ISOLATE CHARGING FROM ALL SOURCES OF SPARKS OR
FLAME. DO NOT SMOKE NEAR CHARGING BATTERIES.
2. Equalize Charging Procedure
(a) "Equalize charging" if done regularly and properly, is the one procedure that more than
any other can ensure that the battery will last through the period of the manufacturer's
designed life. Equalize charging is a procedure by which the battery is given a full
charge, then trickle charged to ensure that all the cells balance out in their degree of
charge. Equalize charging should be performed on the battery at least once per week.
(b) Read all safety precautions before proceeding.
(1) Turn the main switch to the "off" position.
(2) Engage park brake.
WARNING: THE CHARGING PROCESS GENERATES HEAT,
CAUSING ELECTROLYTE LEVELS TO EXPAND. CELLS FILLED
BEYOND THE LOW LEVEL BEFORE CHARGING CAN SPILL OVER
DURING THE CHARGING PROCESS, CAUSING ACID DAMAGE TO
SURROUNDING AREAS AND/OR AN ENVIRONMENTAL HAZARD.
(3) Check electrolyte levels. Fill Only Very Low or Dry Cells with distilled
water, and Only to Low Level Mark.
