Instant Power™.
The LED lights will indicate the charge level as follows:
A red LED indicates a 50% or less charge, and you should immediately recharge the •
Instant Power™.
A yellow LED indicates a 50 to 75% charge. The Instant Power™ may be used, but
•
should be recharged as soon as possible.
A green LED indicates the internal battery is fully charged.

Charging the Internal Battery using the Built-In Charger
6.2
To charge, flip the AC connector on the back of the Instant Power™ up and plug an 1.
18 gauge (AWG) (0.82 mm 2 ) or larger extension cord onto it. (Extension cord not
included; must be purchased separately.)
Plug the other end of the extension cord into a 120V AC electrical wall outlet.
2.
The RED LED will light indicating charging. 3.
The GREEN LED will light when the battery has reached full charge. This could 4.
take up to 72 hours, due to 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.
Charge the Instant Power™ as soon as possible after each use.
5.
Do not use the Instant Power™ while charging the internal battery.
You may also charge the internal battery while driving, using a male-to-male charger
cable (p/n 94500109 – not included). Insert one end of the charger 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 RED LED and the GREEN LED do not indicate charging status
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 charge it for
more than four hours and do not leave the battery unattended or it could explode,
causing property damage or personal injury.
OPERATING INSTRUCTIONS
7.
Jump Starting a Vehicle Engine 7.1
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.
Turn the vehicle’s ignition OFF before making cable connections. 1.
Position the DC cables to reduce the risk of damage by the hood, door and moving 2.
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 metal part of the battery
clips or cut the insulation of the cables.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury.
3.
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post 4.
usually has a larger diameter than the NEGATIVE (NEG, N, -) post.
