7.5 Charging the Internal Battery using the Built-In Charger:
1. To charge, plug an 18 gauge (AWG) [0.82 mm
2
] or larger extension cord into the
charger plug on the right side of the Instant Power™. (Extension cord not included;
must be purchased separately.)
2. Plug the extension cord into a 120V AC electrical wall outlet.
3. The CHARGING (red) LED will glow indicating charging.
4. The CHARGED (green) LED will light when the battery has reached full charge.
This could take up to 72 hours, depending on the age and condition of the battery.
The charger will automatically go into maintain mode and maintain the battery at full
charge without damaging it.
5. Charge the Instant Power™ as soon as possible after use.
NOTE: To reduce the risk of damage to the electric plug or cord, pull by the plug rather
than the cord when disconnecting the Instant Power™.
You may also charge the internal battery while driving, using the male-to-male charger
cable (p/n 94500109 – not included). Insert one end of the accessory cable into the 12V
DC power outlet and the other end into the vehicle’s accessory outlet (lighter socket).
Completely disconnect the charger cable when the engine is not running.
The CHARGING (red) LED and the CHARGED (green) LED do
not operate during this method of charging. Using this method to charge the battery
overrides the maintain mode and the battery can be overcharged. Monitor the progress of
the battery and when it reaches a full (100%) charge, disconnect the charger. Do not leave
the battery unattended or it could explode causing property damage or personal injury.
8. OPERATING INSTRUCTIONS
8.1 Jump Starting a Vehicle Engine
A SPARK NEAR THE BATTERY MAY CAUSE A
BATTERY EXPLOSION. TO REDUCE THE RISK
OF A SPARK NEAR THE BATTERY:
Do not use the Instant Power™ while charging the internal battery.
1. Turn the vehicle’s ignition OFF before making cable connections.
2. Position the DC cables to reduce the risk of damage by the hood, door and moving or
hot engine parts. NOTE: If it is necessary to close the hood during the jump starting
process, ensure that the hood does not touch the battery clips or cut the insulation of
the cables.
3. Stay clear of fan blades, belts, pulleys and other parts that can cause injury.
4. Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post usually
has a larger diameter than the NEGATIVE (NEG, N, -) post.
5. Determine which post of the battery is grounded (connected) to the chassis. If the
negative post is grounded to the chassis (as in most vehicles), see step 6. If the
positive post is grounded to the chassis, see step 7.
6. For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the Instant
Power™ to the POSITIVE (POS, P, +) ungrounded post of the battery. Connect the
NEGATIVE (BLACK) clip to the vehicle chassis or engine block away from the battery.
Do not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect
to a heavy gauge metal part of the frame or engine block.
7. For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from the Instant
Power™ to the NEGATIVE (NEG, N, -) ungrounded post of the battery. Connect the
POSITIVE (RED) clip to the vehicle chassis or engine block away from the battery. Do
not connect the clip to the carburetor, fuel lines or sheet-metal body parts. Connect to
a heavy gauge metal part of the frame or engine block.
If you have connected the clips backwards, an audio alarm will sound.
Reverse the connections and the audio alarm will stop.
8. Crank the engine. If the engine does not start within 5-8 seconds, stop cranking and
wait at least 1 minute before attempting to start the vehicle again. (This permits the
Instant Power™ battery to cool down.)
