Consult Auto Meter if you need more information.
2. Use the Battery Extender only on LEAD ACID AND GELLED
ELECTROLYTE (GEL-CELL) BATTERIES that match the voltage
printed on the front label of the Battery Extender. DO NOT attempt
use on other types of batteries (Dry Cell, Nickel Cadmium, Nickel
Metal Hydride, etc.) commonly found in small home appliances. This
may cause the batteries to burst, resulting in damage or injury to
people and property.
3. DO NOT use your Battery Extender on batteries that are in use. Use
it only on batteries or vehicles that are in storage.

A. Use a three prong grounded extension cord.
B. The cord ends are wired correctly and in good condition.
C. The cord itself is in good condition.
D. Insure that all pins on the extension cord are identical in size,
shape and number as the plug on the Battery Extender.

12. ALWAYS disconnect the Battery Extender from a stored vehicle or
battery before operation.
13. NEVER attempt to charge a frozen battery. Allow the battery to
return to room temperature before connection.
14. ALWAYS use the Battery Extender in an open and well ventilated area.

WARNING:
Explosive Hydrogen gas may be present around batteries.
15. DO NOT use the Battery Extender in direct sun light or adverse
weather conditions such as rain or snow.
16. Never place your Battery Extender above or below the battery.
Locate it as far to the side of the battery as the leads permit. This
prevents acid drips and spills from landing on the Battery Extender
during battery filling or specific gravity testing. This also prevents
battery fumes from reaching the Battery Extender.
17. DO NOT place a battery on the Battery Extender.

on dry land. DO NOT use the Battery Extender where it will be
exposed to moisture or inclement weather, or around combustibles
like trash, flammable liquids and vapors.
Lead Acid Batteries are Dangerous! During use and charging they may generate EXPLOSIVE Hydrogen Gas. This means
YOU MUST carefully read and follow these instructions before each use of your Battery Extender.
GENERAL SAFETY RULES FOR SAFE OPERATION
PERSONAL SAFETY PRECAUTIONS
1. Wear protective goggles or a full face shield.
2. Wear protective clothing. Leave no exposed skin.
3. Have plenty of fresh water and hand soap available for use if acid
should contact your eyes, skin or clothing.
4. Have someone close by in the event you need emergency
assistance when working with a battery.
5. Remove all metal objects (pens, tools, jewelry etc.) from your body.
These items can create a direct short between the battery terminals
and can cause serious burns.
6. DO NOT carry tools or metal objects in the vicinity of a battery.
These items can fall on the battery terminals creating a high current
short. This could result in a fire, burns, explosion, etc.
7. DO NOT touch your face, eyes or other body parts without first washing
your hands. Battery acid can burn and irritate eye and skin tissue.
8. DO NOT allow any source of ignition in the area of a battery. Keep
all flame and spark producing devices out of the area and NEVER
SMOKE near a battery.
9. Use the one hand rule! Keep one hand in your pocket whenever you
make an electrical connection. This reduces the risk of electric
shock to the user.
10. DO NOT attempt to open or modify the unit. DO NOT insert any
object into ventilation holes. DO NOT cover ventilation holes on unit.
