Car Battery Replacement Service
Could you please explain what car batteries are and how they operate?
A car battery is a device that stores energy and converts that energy into electricity through a chemical reaction inside the battery. A vehicle’s starter motor, ignition system, and fuel system are powered by stored electrical energy at the outset. As soon as the engine of a vehicle is started, the alternator supplies the power needed for all mechanical and electrical systems within the vehicle and charges the battery to replace the energy used during starting.

As well as the standard 12 volt battery used to start the engine of an electric car, most electric vehicles have traction batteries as well. A traction battery converts chemical energy into electrical energy as well, however it operates at a higher voltage and is usually monitored by a PCM (Powertrain Control Module).

When Should I Replace My Car Battery?
It won’t start. New batteries are designed to deliver a certain level of power. The number of cranking amps is referred to as the capacity of the battery. During the aging process, a battery’s actual amp output decreases. Once the cranking amps fall below a critical threshold, it becomes difficult or impossible to start the car.
There is a problem with the battery or the charging system if the warning light illuminates. A mechanic should perform several simple tests to determine whether the battery is in need of replacement when the battery warning light illuminates.
There is a problem with the electrical system. A failing battery will result in a drop in the voltage produced by the battery, which may cause certain electrical components, such as the security system, to malfunction. If you are experiencing electrical troubles, you should have your battery tested.
How do mechanics replace the battery?
In order to avoid losing radio presets or stored data in the PCM while the battery is out, a temporary power source could be installed. However, this step is not necessary when the battery is already completely dead.
After removing the negative cable from the battery, the positive cable should be removed as well. Loosen the battery tie-downs and remove the old battery.
Make sure the cable ends and wiring are clean and free of corrosion. The corrosion can sometimes be severe and the cable may need to be replaced or the wiring may require repair.
In addition, the new battery was installed and the tie down system was reinstalled. Battery terminals were treated with an anticorrosion compound. Positive and negative connections were made.
Depending on the model of the vehicle, some PCM programming may be necessary to input battery parameter settings, such as some BMW, VW, and Audi models. In order to maximize the battery’s lifespan and prevent issues with the electrical system, this activity is performed using a specialized scan tool.
In order to verify that a new battery will properly recharge, the car is started and the charging system output is measured and compared with the factory OEM specifications. In general, charging output will range from 13.8 to 14.8 volts, but the specific specifications will vary depending on the product.
Would you advise me not to drive if I have a battery malfunction?
However, if you have a weak battery you may be left stranded if it fails completely and you will not be able to start your vehicle. A defective battery could also cause the alternator to overwork and negatively affect the operation of the vehicle’s electrical system, including the vehicle security system and the shift interlock.

When replacing the battery, it is important to remember the following:
it is important that the electrical connections to the battery posts are of high quality. Connections must be clean, free of corrosion and properly tightened.
In addition to storing a lot of energy, batteries can create intense discharges which can damage your eyesight if short-circuited. It is recommended that cables be attached to battery terminals using insulated tools. Other options include shorting either the positive cable of the battery to ground or directly shorting the positive and negative posts. It is recommended that batteries be installed from a positive terminal to positive wiring and from a negative terminal to body ground. It is probable that the vehicle’s electrical system will be damaged if the polarity is reversed.
The service life of a car battery is usually between four and seven years. Whenever a battery’s capacity to provide power declines significantly after undergoing a load test, it is advisable to replace the battery rather than waiting for the old battery to completely fail.
Disconnecting the batteries should be done only when the engine is off and the alternator is not operating. While the alternator is operating, disconnecting the car battery can lead to a voltage spike that may damage the vehicle’s sensitive electronic components, such as the PCM.

Difficulty starting the car or the engine cranking more frequently than usual.
Diminished power for both internal and external vehicle electronics.

Our mobile technician begins by meticulously loading the required equipment into their pristine van. They will then give you a courtesy call 15 minutes prior to your appointment, informing you of their imminent arrival and agreeing on a secure spot for you to leave your car keys.

Before the technician arrives, ensure your car is parked in a safe and accessible location, and place your keys as per the agreed arrangement.
