A jump start, also called a boost, is a method of starting an internal combustion engine with an assistance of external power source when the battery ordinarily used for starting is unable to provide sufficient output. A temporary auxiliary power source such as another internal combustion equipped device with the same system voltage is connected to provide supplemental power. Once the assisted starting is completed, the engine will operate the alternator to supply the electrical power needed to run and replenish the battery, so the auxiliary source can be removed.
Engines that employ electric start uses an electric motor powered by battery to start. When the engine is running, attached alternator replenishes the battery and provide electrical power used by the equipment or vehicle.
Auxiliary power sources:
Jumper cables (jump leads)
For other uses, see Jumper cable (disambiguation).
Jumper cables also known as booster cables or jump leads are a pair of insulated wires of sufficient capacity with alligator clips at each end to interconnect the disabled equipment/vehicle with an auxiliary source such as another vehicle or equipment with the same system voltage or to another battery. The alligator clips may be covered in insulation to prevent inadvertent shorting. Clips maybe made of copper or steel. Alligator clips are generally marked by black (-) and red (+) to indicate the polarity.
Limitations
The interconnected systems must have the same voltage designation.
Auxiliary source can replenish the dead battery if it is still capable of accepting a charge. After several minutes enough energy is transferred to allow cranking of the engine along with the power from the auxiliary power source that is left connected as the engine is cranked.
If the dead battery is physically damaged, has a low electrolyte level, decayed, or is frozen, a jump start will not repair the battery. A jump start can get the engine started when its primary battery is discharged or is not able to provide sufficient current due to decay or environmental conditions. The power demand for starting the engine increase and battery's ability to provide power decrease with decrease in temperature.
Self-contained battery pack
A portable battery box equipped with attached cables and charger, can be used similarly to using jumper cables. It directly provides starting current to the starter.
Boost charger
Some battery chargers are designed to supplement the power to start the engine. The battery is left to charge for a short period of time and engine is cranked with the charger left connected. The starter receives power from charge that was added into the battery as well as the boost charger.
Hazards
National Highway Traffic Safety estimated that 2,280 people were injured from motor vehicle battery explosions between October 1993. It estimated that 444 or 19% of 2,280 was from jump starting.
