Warning: Jump-starting a car can cause serious injury if you are not careful. If you are unsure of what you are doing at any point, do not attempt to jump-start your car. Ask an experienced friend or technician to show you first. The JUMPER is not your ordinary portable battery, it has a high amperage output up to 300 Amps and you can cause serious injury to yourself or damage to the vehicle if you do not follow directions.
JUNOJUMPER JUMP-START GUIDE – JUNO POWER
Step 1: Please read your car’s owner manual. Some manufacturers do not allow jump-starts, and some require fuses that need to be removed before attempting a jump-start, or other precautionary steps that needs to be taken for a successful jump-start. Some manufacturers place the car battery in a location other than the engine compartment. In this case, your car will have designated jump-start terminals under the hood. If you are uncertain what to look for, please check your car’s owner manual first before attempting any jump-starts.
Step 2: Make sure you are in a dry location to attempt a jump-start. Do not attempt any jump-starts in foggy weather where visibility is an issue. DO NOT attempt to jump-start a car in the rain.
Step 3: Make sure your ignition key is in the “OFF” position or the key is not inserted in the ignition. For smart-key fobs where you utilize a push-start button to start the car, please make sure that it is in the completely off mode.
Step 4: Always wear gloves and eye-protection glasses if available. Put them on if you have them.
Step 5: Before you clamp the jumper cables to the battery pack, please make sure your battery terminals are free from dry battery acid and rust. If you see a dirty terminal, please wipe with a dry paper towel or cloth to free terminals from dirt. You must have a clean connection to jump-start a vehicle.
Step 6: Identify the positive and negative terminals on your car. Usually the positive terminal has “+” sign and negative terminal has a “–“ sign. In most cases, they are noted with Red (+) and Black (-) colors. If your battery is not in the engine compartment, look for the alternative jump-start locations with + and – indicators.
Step 7: Make sure your jumper cables are not connected to the JUMPR device. Clamp the RED positive (+) clamp to the terminal + in your engine compartment.
Step 8: Clamp the BLACK negative (-) jumper clamp to the NEGATIVE terminal (-) in our engine compartment. This is usually very close to the positive terminal.
Step 9: VERY IMPORTANT – make sure the positive and negative clamps are both tightly secured on the terminals. To check if they are “tightly secured”, when you try to wobble the clamp back and forth, you should be able to feel the clamp tightly connected. FAILURE TO DO SO MAY CAUSE DAMAGE TO JUMPER OR CAUSE SPARKS. Despite the size, the JUMPER is an automobile grade battery pack and does have a peak output of 300 AMPS.
Step 10: Make sure the JUMPER is completely off. (JUMPER is off if there are no LED lights on the indicator)ER by plugging in the end of the jumper cable into the battery pack. The port only goes in one way, so please double check before plugging in.
Step 11: Carefully connect the cables to JUMPR by plugging in the end of the jumper cable into the battery pack. The port only goes in one way, so please double check before plugging in.
Step 12: Once the end of the jumper cable is securely plugged into JUMPER and the positive and negative terminals are securely clamped onto the battery or jumper terminals. You may activate the battery by pressing the button on the side of the JUMPR unit.
Step 13: If JUMPER is fully charged, you should see 1-4 Blue LEDs light up JUMPER. This indicates that JUMPER is on and you’re ready to jump-start your car. We recommend jumping cars with at least 2 LEDs on JUMPER for optimal performance. Crank Amperage may be decreased if only one LED is lit.
Step 14: Go to your car and turn on the ignition.
Step 15: In most cases, the car will start. If it fails to start, leave JUMPER connected for a minute or two and try again. If it fails to start after a minute, wait another a minute to start the vehicle.
Step 16: DO NOT leave JUMPER connected to the battery for more than 5 minutes. If you cannot start your car after 5 minutes, there may be something wrong with your car, such as bad starter.
Step 17: If the car starts, DO NOT leave JUMPER connected to the car for more than 5 minutes. Carefully remove JUMPER by unclamping NEGATIVE (black) cable first, then the POSTIVE (red) cable. Extended clamp on the power may cause the damage to your JUMPER product.
Step 18: Unplug the jumper cables from JUMPER unit carefully making sure the red and black clamps do not touch each other.
Step 19: Congratulations, you’ve jump-started your car.
