![]() ![]() Car battery replacement free#Connections must be clean, free of corrosion and properly tightened. The quality of the electrical connections to the battery posts is important.A faulty battery may also needlessly overload the alternator and could adversely affect the operation of the vehicle’s electrical system, including the vehicle security system and the shift interlock. Yes, but if you have a weak battery you might be left stranded somewhere if the battery dies completely and you cannot start your car. Is it safe to drive with a battery problem? Generally, charging output will be in the range of 13.8 to 14.8 volts but the exact specifications vary by make and model. ![]() The car is started and charging system output is measured and compared against the factory OEM specification to ensure that the new battery will properly recharge.This step, performed using a specialized scan tool, is necessary to maximize battery life and prevent electrical system malfunctions. Some vehicles, for example some models of BMW, VW, and Audi, may require PCM programming to input battery parameters.The positive terminal is reconnected followed by the negative terminal. Anti-corrosion compound is applied to the battery terminals. The new battery is installed and the tie down system is reinstalled.In some cases, corrosion can be extreme and the cable may need to be replaced or wiring repaired. Cable ends and wiring are carefully inspected to ensure cleanliness and no corrosion.The battery tie down system is loosened and the old battery removed. The vehicle’s negative cable is removed from the battery, followed by the positive cable.When the battery is already completely dead, this step is unnecessary. A temporary power source might be installed to avoid the possibility of losing radio presets or stored data in the PCM while the battery is out.If you are experiencing electrical malfunctions, it’s a smart idea to have the battery tested. Once a battery has started to fail, and the voltage produced by the battery drops, then vehicle electrical components can malfunction, such as the security system. Should a battery or charging system warning light illuminate, a mechanic should perform a few basic tests to determine if a battery replacement is needed. Battery or charging system warning light is illuminated.As the battery ages, the actual amps that a battery can supply becomes lower than its original rating Once the cranking amps fall below a critical threshold, it will be difficult or impossible to start your car. This capacity is referred to as the cranking amps rating of the battery. A new battery has a specified capacity to provide power. Traction batteries also convert chemical energy to supply electrical energy but operate at higher voltages and often are monitored by the PCM (Powertrain Control Module). Most electric vehicles have a traction battery which is in addition to the standard 12-volt battery that is used to start the car engine. Once your car engine is running, the alternator supplies the electricity needed for all vehicle systems and charges the battery to replace the electric energy used when starting a car. The stored electrical energy is used to initially operate the starter motor, ignition system, and fuel system on your vehicle. What are car batteries and how do they work?Ī car battery is an energy storage device that relies on a chemical reaction within the battery to produce electricity. ![]()
