This tool is used to register the new battery in the on-board computer if the system is open. Even automobiles equipped with BEM can configure the recently purchased replacement battery in a closed system. Additionally, error codes that are common or manufacturer-specific are typically read from the system or removed. This is true even if there was a voltage drop during battery replacement or if the car’s on-board computer was unplugged.
The Banner Battery Service Tool (BBST) can generate the Battery Energy Management code (BEM code) even for Audi models, which, in contrast to other brands, always request a code when changing batteries. This ensures that the battery change is properly recorded and that various functions are not restricted. The Banner Battery Service Tool (BBST) also has a system check that examines the entire charging system, including the battery and alternator, and it has a built-in product search to help you select the right replacement battery.
Only the configuration or actual values of the old battery stored in the control unit are reset by entering the BEM code, and the current mileage is saved.
It’s crucial that you utilize the Memory Saver together with the Banner Battery Service Tool (BBST):
The power source of the electrical system must be externally powered, for example using a Memory Saver, to prevent the deletion of vehicle settings and codes when batteries are changed. Car data loss can be safely avoided by maintaining voltage via the OBD (On Board Diagnostic) socket in the vehicle. Vehicle information, such as the navigation settings, phone book, radio station, electronic seat position, etc. are remembered when the battery is changed. Another benefit is that, when using the Memory Saver to replace a battery, re-registering is typically not required.
It is not problematic to use a Memory Saver for voltage management and a Banner Battery Service Tool (BBST) simultaneously because the included adapter makes it simple to connect both devices.
The car system logs the failed battery for an older battery. Without a BEM code, the vehicle won’t recognize that a new battery has been installed if one is installed. To inform the energy management system of the new battery’s status, a BEM code must be entered, or the new battery must be initialized using a multi-brand diagnostic tool, such as the Banner Battery Service Tool (BBST). The system must initially configure the new battery condition if neither is available. The system picks this up more quickly the more “trigger events” (impulses, signals, such as starts, cold starts, and cycles) there are in the battery. The amount of time it will take depends on the manufacturer’s specs. It can last anything from two operating hours to six days. Within a few hours, the vehicle computer often gradually unleashes the previously restrained systems, such as the air conditioning system’s full power. The error memory may take longer to reset visible error messages. It often takes a few days (up to 6 days depending on the manufacturer) for the system to detect the new battery status and reset the error signals if this is not done actively through a Banner Battery Service Tool (BBST).
More and more automakers advise or demand that the system configure the new battery. Then, you must go to a mechanic so that a diagnostic tool may alert the energy management system that a new battery is in place and that the stored data are reset. These days, this so-called initialisation may be completed for many different auto models using multi-brand diagnostic instruments, such as our Banner Battery Service Tool (BBST). The control unit often keeps track of the mileage at the time the battery is replaced in addition to resetting the configuration or actual values for the old battery.
Conclusion: The only immediate benefit of purchasing and BEM coding an original replacement battery over a battery from an independent aftermarket that does not have BEM coding is that all systems are immediately functional. Please take note that the battery often achieves this functionality without a BEM code after a period of time and a number of trigger events (impulses, signals, e.g. starts, cold starts, cycles).
Even without entering a BEM code, installing a high-quality replacement battery eliminates any safety risks, overcharging concerns with the new battery, increased battery wear, and potential damage to the vehicle’s electronics or other components. These days, this so-called initialization process can be completed for multiple auto models using multi-brand diagnostic instruments, such as the Banner Battery Service Tool (BBST).
Please be aware:
In a car with a start-stop function that comes standard with an EFB or AGM battery, never install a normal wet-cell battery. If more power is required, an EFB or AGM battery must be utilized. in the same housing unit and in the same performance category.
PS: Minor variations in capacity or performance during a cold start have no impact on the electrical system’s safe start and optimal power delivery.
It is crucial that the new battery is set up in the system for start-stop vehicles with a battery energy management system when switching from EFB to AGM batteries (BEM). This is the perfect use for the Banner Battery Service Tool (BBST).
Banner advice for luxury and upper-class vehicles:
Particularly with two-battery car electrical systems, the disconnection sequence must be strictly followed while removing the old battery (or batteries), as failure to do so could trigger the safety battery contacts. According to the operating instructions, for example on a VW Phaeton V10 TDI, you must first detach the left-hand AGM battery and then the right-hand conventional wet-cell battery in this situation (our test car was built in 2006).
The proper equipment for replacing start-stop batteries is:
- Automatic creation of the battery energy management code particular to the manufacturer (BEM)
- reading and erasing error codes particular to a manufacturer
- Battery, starting power, and charging system evaluation
- Textual explanation with illustrations showing where to place the OBD diagnosis plug
- Y adapter for Banner Memory Saver wiring system voltage retention (optional)
- Battery allocation: Includes 30,000 utility vehicles and more than 41,000 autos.

Can I change the battery in my Audi myself?
You can still install the battery yourself, but you’ll need to either take it to the dealer or reprogram the computer using diagnostic software like VCDS.
Do I need to code my battery?
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.
The selection criteria will be confirmed on the next screen. Press “Continue,” then “Close Program,” “Remove Battery Support Unit,” and so forth.
Does the automobile need to be programmed following a battery change?
The engine-management computer will reprogramme itself following a battery change. After roughly five minutes of driving at a moderate speed, it happens naturally and is referred to as a “relearning process.” Tom: The radio presets are the only item that won’t change itself.
What is the price of a new Audi battery?
How much would a new battery cost for my Audi? Prices for a replacement automobile battery varies from roughly $45 to $250 depending on power, size, and quality.
How long do batteries for Audi last?
The battery life of an Audi vehicle will differ. Any automotive battery should typically last between three and five years. Although a battery’s lifespan can be extended with proper maintenance, it is typical to need to replace a battery every three years.
Do Audi Q7 batteries require coding?
It is entirely present. It is necessary because the energy management system can modify the alternator’s charging profile according to the battery’s age and condition. You’ll have a hard time if you don’t listen to Ross Tech. My Audi dealer told me today that there was no reason why codding was required for a 07 model.
What should I do after changing my car’s battery?
wonderful question In order for the alternator to properly charge the battery after a car battery replacement, you should drive the vehicle for roughly 30 minutes.
A battery replacement typically necessitates a radio and computer reset on the car. Your radio presets may need to be reset as a result of this.
After changing the battery, the computer occasionally does not restart itself. The dashboard may still display an error code. Use an OBD-II diagnostic scanner to identify the issue’s root cause in this circumstance. You can reset the computer by looking up the code.
You can *clean the battery terminals with a wire brush and battery cleanser every six months** to extend the life of your new battery. When you can, park in a garage to shield your battery from chilly temperatures.
As a heads up, batteries often last for five years. Although experts advise buying a new battery every three to four years, many last far longer.
After I stop replacing my battery, how do I reset it?
response given by Just adhere to these simple instructions to reset your car: Take two to three minutes to unplug the battery cable. Start the vehicle after reconnecting the battery. To allow the engine control systems to detect any potential issues, drive the automobile for at least 10 kilometers.
Does changing a car battery require a memory saver?
After giving a seminar recently, a student who works in a store in Mississippi sent me an email to ask about one of the issues I covered in the session. In essence, I had reminded the audience that before technicians perform any welding on vehicles, the automakers advise (and I-CAR teaches) that they should first disconnect the vehicle’s battery and remove (or pull back) any wiring harness or electronic components that are within 12″ of the weld area.
If the technician is using a “memory saver,” a cheap device that typically uses a 9V battery plugged into the car’s auxiliary power outlet (or cigarette lighter to keep power directed toward the car’s radio or other components to keep power directed toward them to maintain their memory settings, the man from Mississippi inquired about some of the electrical issues. The Mississippi technician questioned whether using a memory saver was a better option than unplugging the battery and maybe losing some electronic memory data.
Although I was fairly certain I understood the answer, I chose to consult a few of the technical authorities in this field that I know and respect. They all came to the same conclusion: Memory saver usage is not advised.
Will Latuff, manager of the fourth-generation Latuff Brothers collision repair shop in St. Paul, Minnesota, remarked, “We don’t utilize memory savers. They are ineffective and not worth the danger. I-CAR advises against using them as well.
A memory saver could put systems at risk, according to Peevy, because it can close circuits that battery removal opens to protect the system.
Axalta Coating Systems’ George Hogan, a business development manager, concurred that welding can subject car electronics to excessive voltages and amperages.
If the modules are “alive,” powered on by either a connected battery or an inserted memory saver, there is also probably an increased danger of fault codes being saved if the circuitry is exposed to unexpected signals, Hogan added.
Hogan claimed to have recently spoken with an engineer from an automaker who brought up the fact that some vehicle electronic systems continue to run even when the key is off.
Consider keyless entry systems, which are always searching for a signal from the electronic key, according to Hogan. If welding is done to the car without the necessary precautions being taken initially, this could place these systems at even greater risk.
Chuck Olsen, director of advanced diagnostics and technical support for Collision Diagnostic Services, the business that can remotely read and reset diagnostic codes on a car anywhere in the nation using a tool a shop links to the car and the Internet, stated, “I concur with the others.
The aim of removing the battery is defeated by a memory saver that was inserted while making repairs since it creates an electrical conduit through the system. They might be acceptable to use for a straightforward battery replacement, but not for additional repairs.
Larry Montanez, a collision damage analyst with P&L Consultants, LLC, and Lange Technical Services, Ltd., as well as a former I-CAR instructor and area training coordinator in the Northeastern United States, added his perspective to the discussion.
I-CAR and I don’t advocate memory savers, Montanez remarked.
Memory savers can cause some delicate electrical components to break or let airbags deploy. Electronic modules can sustain damage from electromagnetic induction (EMI). Whether the battery is attached or not, EMI can infrequently happen during MIG welding but is quite prevalent during squeeze-type resistance spot welding.
In order to prevent a short to ground in the system, several OEMs mandate that the supplemental restraint system (SRS) modules be unplugged during welding, according to Montanez.
The responses I received to the query didn’t surprise me, but it was still beneficial to have it verified by numerous trustworthy sources. By employing a low-tech memory saver, you run the risk of destroying costly vehicle components. You should also stay away from work that has been billed but not completed. When you just place something back down or disconnect the battery at the terminal, avoid charging anything or the battery to R&I. Charge for it if you do it, and if you do it for money, charge for it.
