Never open battery caps with your face directly over the battery. Use baking soda or an approved cleaning agent to neutralize any spilled acid.
Never smoke in battery charging areas.
Keep tools and other metallic objects away from uncovered batteries.
Do not strike the sides of the battery with any tool that could produce a spark.
Have a dry-chemical fire extinguisher in charging areas or readily available.
Neutralize static buildup before touching a battery by contacting the nearest grounded surface.
Always handle batteries in a well ventilated area.
Never touch both battery terminals with your bare hands at the same time.
Remove rings, watches and dangling jewelry when working with or near batteries.
Only use insulated/non-conducting tools to remove cell caps. Never lay tools or other metal parts on top of a battery.
Exposed terminals, even on disconnected batteries, are an electrical shock hazard.
Ensure charger is turned off before connecting or disconnecting a battery to prevent arcing.
Jumpstarting your battery
Charging your vehicle's battery without the proper equipment or precautions jeopardizes your safety and the safety of those around you. Please take care in having the correct protection and tools.
What You Need to Know
Always wear proper eye protection and never lean over battery
Inspect both batteries. Do not jump start a damaged battery
Be sure vent caps are tight and level
Make certain that the vehicles are not touching and both ignition switches are turned to the OFF position
Never allow the jump-start cable clamps (red and black) to touch each other or another common metal conductor. This could cause damage to the unit and/or create a sparking/explosion hazard. Always switch off the jump-starter ON/OFF switch and store the jump-start clamps on the appropriate case clamp posts on the back of the unit after use.
Jump-start cable clamp connections at the vehicle's battery terminals must be positive to positive (red clamp to batter "+" and negative (black clamp) to the grounding point such as the metal frame of the vehicle. A reverse polarity connection (positive to negative) may cause damage to the unit and/or create a sparking/explosion hazard.
Turn off ignition and all vehicle accessories.
Make sure the Portable Power System is fully charged and jump-starter ON/OFF switch is in the OFF position. Turn any additional functions of your Portable Power System off.
Securely connect the red positive (+) booster clamp to the positive (+) terminal of the vehicle's battery.
Securely connect the black negative (-) booster clamp to the grounding point such as the metal frame of the vehicle
Turn the Portable Power System's jump-starter ON/OFF switch to the ON position.
Crank engine in 5-6 second bursts.
Do not crank the engine for more than 6 seconds. The jump-start feature is designed for short-term operation only. Operating the jump-start feature for more than 6 seconds may cause damage to the unit. Allow the Portable Power System to cool down for at least 3 minutes after each jump-start.
Once engine has started, TURN THE JUMP-STARTER ON/OFF SWITCH TO THE OFF POSITION AND DISCONNECT THE BLACK NEGATIVE CLAMP FIRST and then the red positive clamp.
Recharge the Portable Power System as soon as possible after each use.
If possible, bring the two cars together nose to nose, about 18" apart. Be sure you're parked well away from traffic. Make sure both cars have their parking brakes on.
Make sure both cars are turned off. Put automatic transmission cars in Park. Put manual transmission cars in Neutral. Set the parking brake firmly so the vehicle cannot move.
Determine which terminals are positive and negative on both batteries. Look for "+" sign or red indicator for positive, "-" sign or black indicator for negative. The positive terminal is usually wider than the negative. Caution: Once you begin the next steps, do not touch the metal portion of the jumper cable clamps to each other or any part of the car except the proper battery terminal.
The jumper cables are marked with colors or stripes to help you keep track of the two separate wires. Attach one end of the positive cable clamp to the positive terminal of the dead battery (the positive cable may have a stripe, or if the cables are marked with red and black, the red cable is positive).
Attach the other end of the positive cable to the positive terminal of the good battery.
Attach one end of the negative cable to the negative terminal of the good battery. YOUR CABLES ARE NOW LIVE! DO NOT TOUCH THE REMAINING CABLE CLAMP METAL PORTION TO YOURSELF OR ANY PART OF THE CAR EXCEPT THE NEGATIVE TERMINAL OF THE DEAD BATTERY.
Attach the other end of the negative cable to a metal section (bracket, block, etc.) of the engine away from any moving parts (CAUTION: belts and pulleys can be dangerous). Connecting this cable last, and away from the battery, will avoid sparks and potential hazards at the battery.
Make certain everyone is clear of the engine compartments - don't allow hands or clothing to be caught by moving engine parts.
Start the engine of the good car. Allow it to run for 1-2 minutes. Rev the engine slightly by pressing on the gas pedal lightly.
Start the engine of the dead car. It may take more than one try, but do not try to restart it more than three or four times. Caution: Some car's electrical and computer systems may be damaged by running the engine with a dead battery. Check your owners manual or service provider for guidance.
If the car still won't crank (start):
If the dead car gets no "click" when you turn the key, the booster cables may not have a good connection at the terminals. Turn off the engine and try rocking the cable clamps back and forth to get the clamps to dig into the terminals. Or, try another ground point to attach the negative cables. Retry from step 7. If the engine still won't start, allow the good car to run for 5-10minutes while hooked up to the dead car. Rev the engine slightly. This may build a charge in the dead battery and allow you to restart. If these steps do not work after three or four more tries, stop trying to jump-start. The battery may be shorted internally, or the dead car may have other electrical problems besides the battery. Continuing to try the jump-start can cause damage to the electrical system. Have the car towed to Pep Boys for service.
