BATTERY CARE AND MAINTENANCE
Lead acid batteries can produce explosive mixtures of hydrogen and oxygen. Take
the following precautions:
● Never leave batteries in an airtight or sealed enclosure.
● Charge batteries in accordance with the instructions given in this manual.
● Keep all sparks, flames and cigarettes away from batteries.
● Make sure cables are tightly connected to terminals to avoid sparks.
● Wear proper eye and face protection when installing and servicing batteries.
Lead acid batteries contain sulphuric acid electrolyte which can cause severe burns
to body tissue. Take the following precautions:
● Avoid contact of the electrolyte with skin, eyes or clothing.
● Never remove or damage vent valves.
● In the event of an accident, flush with water and call a physician
immediately.
DANGER OF BURNS IF TERMINALS ARE SHORTED
Lead acid batteries are capable of delivering high currents if the external terminals
are short circuited. The resulting heat can cause severe burns and is a potential fire
hazard. Take the following precautions:
● Do not place metal objects across battery terminals.
● Remove all metallic items such as belt buckles, watches, bracelets and rings
when installing or servicing batteries.
● Wear insulating gloves when installing or servicing batteries.
● Use insulated tools when installing or servicing batteries.
Thermal runaway is a condition in which the battery temperature increases rapidly
resulting in extreme overheating of the battery. Under rare conditions, the battery
can melt, catch on fire, or even explode. Thermal runaway can only occur if the
