Do I need to reprogramme my car after a battery change?
I’m here. Battery programming has nothing to do with changing the battery. When jumped, a car that had completely lost electricity from its battery due to the dome light being on will function normally. The key fob can require programming when the battery is changed. As the vehicle computer is reset, the key fob’s programming to the computer will be lost.

Should an automobile battery be coded?
The customer may soon need to go back to the garage if the batteries are not put properly. The battery management system of the automobile won’t function properly without battery coding, and several vehicle operations may stop. The worst-case situation is that it might even be impossible to start the car.
Before beginning any work, a battery support unit should be installed. This keeps the electronic memory of the car. The system of the car could reset to the factory default if there isn’t a support unit.
Since the coding portion of this process cannot be skipped, it is crucial to follow the installation process from beginning to end.
To keep codes and information about the instrument display, connect a battery support unit, such as the BAT490. Throughout the process of installing the battery, this should be connected.
Make sure to unplug the negative terminal of the old battery before the positive one…
Install the appropriate new battery, being sure to connect the positive terminal first and the negative terminal after. Make sure the replacement battery’s vent tube is installed if one exists.
Make sure the battery is positioned appropriately in the tray and is fastened in place.
Choose “Energy Management” from the drop-down menu under the “Diagnosis” heading.
Verify the fault codes in the error memory. If there are no codes, move on to the next step, but before you clear any fault codes and begin the battery coding procedure, make a note of any…
Enter the battery serial number when requested. The barcode on a Bosch battery contains the serial number. You only need to input the first 10 digits of this 13-digit number.

Can I replace a start/stop battery on my own?
BERLIN: When you operate a vehicle with a stop-start system, replacing a car battery is not as simple.
German industry leader in technical inspection Vincenzo Luca, an expert, shares his opinion.
A standard flooded battery won’t survive very long in a stop-start vehicle, which demands a stronger power pack to handle 17,500 starts annually as opposed to 750 for a regular vehicle.
Batteries for stop-start applications also have greater fast-charge capacity and superior vibration resistance. Furthermore, they perform better when their charge is low.
When the accelerator or brake pedal is depressed, the engine automatically restarts. This is known as a stop-start.
If a standard battery is used in a stop-start vehicle, the entire electrical system may develop problems and even get damaged.
People who change the battery on their own often experience strange failures thereafter, such as electrically powered windows not working.
Installing a stop-start battery is best left to a shop or dealer. They will be equipped with the diagnostic tools required to re-set the active energy management system of the vehicle.
Reprogramming equipment can be bought, however it’s only advised for skilled hobby mechanics to perform it themselves.
Short-circuiting the plus and minus terminals by improperly attaching the power wires is one of the key risks associated with battery replacement. Burns and other injuries may result from this.

Which batteries does Volkswagen use?
In a news release, Volkswagen stated that three new, independent business partnerships are now a part of its EV battery development plan.
The first is a partnership with Belgian cathode materials supplier Umicore. Umicore will support VW in its supply chain with regard to the manufacturing of EV battery cells in Europe. This will start in 2025 at Volkswagen’s gigafactory in Salzgitter, Germany, with a 20 GWh initial production capacity.
By 2030, the joint venture hopes to reach a production capacity of 160 GWh annually. That battery capacity equates to nearly 2.2 million BEVs, according to Volkswagen.
Volkswagen has invested in 24M Technologies, a US-based battery firm founded by MIT alumni who has rebuilt the conventional battery cell using “SemiSolid lithium-ion technology,” in addition to the joint venture. These novel cells have the potential to reduce production space by 40%, improve product recycling, and reduce CO2 emissions during battery manufacturing.
Last but not least, Volkswagen has a long-term contract with Vulcan Energy Resources Ltd., a producer of lithium in Europe that wants to be the first to do so with net-zero emissions of greenhouse gases. The legally binding agreement calls for Vulcan to give VW lithium hydroxide over a five-year period starting in 2026. According to Volkswagen, this innovation will assist meet future European domestic EV battery cell demand.
In the press announcement, Thomas Schmall, CEO of Volkswagen Group Components and a member of the board of management of Volkswagen Group for Technology, addressed all three agreements:
Volkswagen is moving quickly and consistently with its battery strategy. Performance, cost, and sustainability must be at the forefront of Volkswagen’s unified cell from the beginning. With our new partners, we have taken a step toward achieving this objective. We will together concentrate on crucial facets of the battery value chain and create cutting-edge technology.
