Battery Charger Specific Warnings
Read all of the warnings below before operation. A failure to read and follow each of the
warnings may result in electric shock, causing serious injury or death.
Warning!! While charging, lead-acid batteries produce hydrogen gas which is extremely
flammable. They generate this gas during normal operation and, at a high level, during charging.
If any spark causes the gas to ignite, the battery could explode, sending out shrapnel-like
pieces of battery casing and extremely caustic battery acids in every direction, with extreme
force and speed. Even the slightest spark will suffice to ignite hydrogen gas. Pay strict
attention to, and follow all of the warnings, each time you use the battery charger.
1. Only use this charger indoors on dry, flat, stable surfaces. Any contact with water will
create an electric shock hazard resulting in serious injury or death. Never expose the
battery or charger to wet conditions. Do not stand in water or have wet hands when
contacting the battery or the charger. For water avoidance, locate all non-wheeled
chargers at least 18” off of the floor.
2. If charging a marine battery, do not charge on a boat or near the water. Do not charge
on a pier or a dock. The boat must be indoors, on a trailer, or you should remove the
battery from the boat and take it indoors. For marine charging, do not connect the
charger cables to the battery in the bilge or engine compartment of the boat. Follow the
boat manufacturer’s battery charging guidelines.
3. If the charger has defective or damaged wires, power cord, plug, or clamps, do not plug
it in and operate it. Have any damaged or defective parts repaired by a qualified
technician.
4. Do not alter power cord, plug, or clamps.
5. If the charger has been dropped or suffered a sharp blow, do not use it until it has been
checked out by a qualified service technician.
6. Never attempt to disassemble the battery charger. When service is needed, go to a
qualified service technician.
7. When wiping down or cleaning the charger, make sure the unit is unplugged from the
power outlet and not connected to a battery.
8. When unplugging the unit, grasp the power plug, not the power cord.
9. Always operate the charger in a well ventilated area.
10. Never operate the charger in close proximity to fuel tanks or gas cylinders.
11. Do not smoke anywhere near the charger. Do not operate the charger near any open
flame or a heat source of any kind.
12. Do not permanently mount the battery charger to any vehicle or boat.
13. Never charge a frozen battery.
14. Never connect both charger clamps to the same post.
15. Do not allow the two output battery clamps to come in contact with each other.
16. Unless the manufacturer’s directions state otherwise, always charge the battery with
the cell caps on.
17. Always unplug the battery charger before connecting or disconnecting battery clamps
from a battery.
