It's best to ask a professional for help. John Banta, Consumer Reports’ lead battery tester, warns that you could fry a key electronic component by not following the proper procedures, and there are the time-old concerns about sparks and battery acid. “For example, attempting to jump-start a damaged or frozen battery could cause significant damage to the vehicle and worse, individuals around the vehicle.” However, if proper steps are not taken, there is no guarantee this method won’t cause damage to the vehicle,” says David Bennett, AAA’s manager for repair systems.
#JUMP STARTERS AT AUTOZONE PORTABLE#
They are portable and provide the required amperage to jump start an empty battery.“When a vehicle battery dies, the most common solution is to jump-start the battery using jumper cables and another vehicle. Jump boxes consist of a maintenance-free battery attached to cables in a pack. If you want a plug-in unit, you should consider features such as the float-charge option, multiple-amperage settings, and the various charging modes. Plug-in units are battery chargers that deliver enough amperage to help turn your engine on. Jump boxes are maintenance-free jump starters with jumper cables attached to them. There are two types of car jump starters: plug-in units and jump boxes. The outlets eliminate the concerns that come with incorrect connections and the creation of arcs near battery terminals. Can jump starters be powered from cigarette lighters?Ĭigarette lighter outlets can be used in place of jumper cables to interconnect the 12-volt power outlets of two vehicles. Vehicles with six- to eight-cylinder engines need 200 to 300 amps. A rough estimate of petrol/gas engines shows that a four-cylinder car engine requires a jump starter with 150 to 200 amps. What size jump starter do you need?Ĭars have various kinds of engines that require different cranking currents. Auto jump starters do not have a power on and off switch they transfer current as soon as the clamps are connected to the terminals. Turn on the power on the jump starter to transfer the current to the dead battery. The black clamp is for negative and the red clamp is for positive. Be sure to match the colored alligator clamps. You hook the jumper pack to the auto battery. High-discharge lithium-ion batteries are also available. Jump-starter batteries are made out of lithium, which make them small and compact. What type of battery is in a jump starter? Simply put, it should match the starting amps of your car battery. Be sure to look for a battery with 225 or more amps and 900 or more peak amps. Batteries with high peak amps generate more power for your car battery. The device should have sufficient cranking amps and peak amps to start a car during an emergency. What strength of battery should be in a jump starter? Here are some frequently asked questions about these devices. They operate as jumper cables but they dont need an extra vehicle to generate the power required to boost the low or dead battery. Jump starters are portable battery devices used to start a vehicle when the car battery is low.
