LEAD ACID BATTERY CHARGING
Table 2 – Charge parameters
Note: The most common type of charge method at present is the three stage plus equalization.
This outline is based on this type of charging method. Check with your charger manufacturer
for specific settings for their equipment. Please note, if “topping up” with water is required
more than once every two (2) months, the voltage settings are too high on your system.
ACTIVATING INSTRUCTIONS/MAINTENANCE FOR A WET BATTERY (LEAD ACID)
Caution: Always wear the proper personal protective equipment (goggles, gloves,
clothing) when handling batteries and electrolytes.
WARNiNg:
· WET BATTERIES MUST BE FULLY CHARGED BEFORE BEING DELIVERED TO THE END
USER. PLEASE REFER TO THE “INITIAL CHARGE OF WET BATTERIES” SECTION OF
THIS DOCUMENT.
· ONLY ADD DISTILLED WATER TO WET BATTERIES. UNLESS INSTRUCTED
BY ROLLS TECHNICAL SUPPORT, NEVER ADD MORE ACID TO THE BATTERIES
AT ANY TIME.
· FAILURE TO DO SO WILL RESULT IN MALFUNCTION AND VOID THE WARRANTY.
CLEANiNg
Batteries should be kept clean at all times, including storage or usage. If stored in a dirty
area, regular cleaning should be performed. Before doing so, ensure that all the vent
caps are tightly fastened. Using a solution of water and baking soda (100g per litre),
gently wipe the battery and terminals, then rinse with water.
iNiTiAL CHARgE of WET BATTERiES (LEAd ACid)
1. Inspect batteries for damage. Important: read warning label on batteries
before proceeding.
2. Wet batteries are fully charged and tested before shipping, but do self-discharge
during transportation and storage. The first charge brings the battery to an operational
state. Before this charging process, the cell electrolyte level should be checked, making
