What battery do I need for my BMW?

FREQUENTLY ASKED QUESTIONS – What battery does a BMW vehicle use? Your BMW car batteries should match the specifications of your current model. Most BMW vehicles, including those in the X3, X5, 3, 5, and 7 series, use BCI Group 94 49 H8 batteries. These batteries are also interchangeable, as they have roughly the same dimensions.

How long does a BMW car battery last? Automotive batteries for BMWs usually last between three and five years.
A lot of factors can affect the life of your battery, including temperature, battery type, design, specifications, and driving habits.
Do BMW cars need a specific battery? Newer BMW models, especially those that were launched after 2002, are equipped with Intelligent Battery Sensors.

This means that you need to register your battery to avoid issues later on. Can I replace a BMW battery all by myself? Locating and replacing the battery is usually a straightforward process, so you can do it on your own. Just remember that if your BMW is a newer model, you will need to register it using a scanner tool.

Also, make sure that the new battery has nearly the same specs as the previous one.
What happens if your BMW battery dies? If your BWM’s battery dies, you unfortunately won’t be able to start your car.
You can try jump-starting the battery by connecting it to a healthy battery from another car using jumper cables.

Even if the battery is located in the rear of the vehicle, you can jump-start it from the front.

Does E46 battery need to be programmed?

Thread: 2006 E46 – Replace battery. reprogram computer. Really?

Most people say they have no issues.
I replaced with a Duralast H7-DLG (basically drop in replacement).
I even came across some video detailing the order to remove the cables which I did.
Put everything back together.bang car turns over like a champ.
No check engine light, no issues with radio.
Only had to set the clock.

According to one site the only models that need this “reprogramming” treatment are: 2002 and newer 7-Series E65/E66 chassis 2003 and newer 6-Series E63/E64 chassis 2004 and newer 5-Series E60/E61 chassis 2005 and newer X5 E53 chassis with N62 engine 2006 and newer 3-Series E90/E91/E92/E93 chassis 2007 and newer X5 E70 chassis 2008 and newer X6 E71 chassis AKA: not my vehicle.

To make things more confusing.the main indicator that programming is needing is a circuit board attached to the NEG terminal (not on mine either).
Also, I have been checking battery voltage and alternator voltage through the instrument cluster.
So far the battery is holding strong at 12.5V, and the alternator is 14.1-14.3 depending on accessory usage.

Should I really be concerned with damage to my vehicle? Agreed with later posters, no reprogramming necessary. One trick, however, to preclude any memory issues in the car like seat memories, radios/radio clock and instrument panel clock, perhaps fuel trim, etc., is to use a battery jumper on the terminal clamps in the engine compartment before you remove the battery.

Just put a plastic ziplock bag over the positive terminal clamp on the trunk battery when you remove it to preclude it touching anything, wrap it up with electrical tape out of the way. Then remove the negative terminal clamp and the battery vent hose (watch for the right angle nipple that is stuck in the battery.new one won’t come with it!) and remove/replace the battery, etc.

04-11-2019, 09:42 AM Always remove the negative/ground/earth cable from the battery FIRST. The only thing you’ll loose when swapping the battery is the time in the clock. Now, if you leave the car without power fir a day or so you will likely loose the radio presets.

04-11-2019, 08:36 PM ^ very important and excellent advice.
06-19-2019, 09:44 AM I have the same vehicle, 2006 325ci with 43K mi.
Which I store every winter.
I usually start the car every week while it’s stored but this year missed a couple of weeks at the end of winter and the battery went completely dead so I left it alone.

This spring I replaced the battery, the car started fine but the “check engine soon” light on the dash went on and doesn’t go off. All maintenance was up to date before I put it away for the winter. It’s difficult to believe that there’s anything wrong mechanically with the engine but I’m definitely not a mechanic.

Any ideas on how to get the light to go off without incurring the cost of a mechanic? 06-20-2019, 08:25 AM You can buy yourself a pocket scanner, or something like this: Okay, now some unasked for advice.1) Pull the battery out of the car when you store it. Buy a battery charger, and charge the battery once a month.2) You are doing more harm than good starting the car and not driving it around during the winter.3) Add fuel stabilizer to the gas, and fill it all the way to the top.

06-23-2019, 10:56 AM Really? How old are you, I haven’t had a conversation like this since High School.
Anyway, for those searching on thread to actually find an answer: The E-46’s do not need to have the battery registered, for it still has stock voltage regulator.

If you own a newer E-9x series of vehicle, the DME controls the voltage output based on the age of the battery as it was registered. If you do not register a new battery, you run the risk of over-charging the battery, thus a shorter lifespan.

Do you have to reprogram BMW after battery replacement?

What is BMW battery registration and coding? – Before we dig into the process of battery registration, let’s focus on what BMW battery registration actually is. To put it simply, battery registration is a process of updating your vehicle with information that a brand new battery has been installed in your car.

What’s important, it should be performed each time you change the battery in your 2002 or newer BMW.
As your battery gets on in years and gradually loses its charging capacity, the vehicle adjusts the amount of energy needed to recharge to operate at optimal levels.
The older the battery the more charging it requires.

Registering your battery lets your engine control module (known as DME — Digital Motor Electronics) know that a new one is installed and as a result, the vehicle will reset the old battery statistics and won’t try to overcharge the new battery thinking the previous one is still inserted.

How do I know what size battery my car needs?

Download Article Download Article You go to start your car only to discover that the engine won’t start and the headlights won’t turn on. That’s a sign that it’s time to check the battery. Not sure how? Don’t worry—this article will walk you through how to check your car battery step by step with either a voltmeter or a power probe.

1 Turn your ignition off.
2 Remove the battery’s positive terminal cover. Check and clean the battery terminals. Advertisement
3 Connect your voltmeter’s positive lead to the positive terminal on your battery. The positive lead on a voltmeter is usually red.
4 Attach the negative voltmeter lead to the negative battery terminal.
5 Check the voltmeter. If your battery is in good condition, the voltage should be between 12.4 and 12.7 volts. A reading lower than 12.4 volts means that your battery needs to be charged.
- If the reading is lower than 12.2 volts, “trickle charge” the battery, which is a slow charge. And then re-check.
- If the reading is over 12.9 volts, you have excessive voltage. Turn on the high beams to remove excessive voltage surface charge. Over voltage may be an indication the alternator is over charging the battery.
- While you have the voltmeter handy, you may also want to do load testing,

1 Remove the battery’s positive terminal cover.
2 Connect your Power Probe’s positive lead to the positive terminal on your battery. The positive lead on a voltmeter is usually red.
3 Attach the Power Probe’s negative lead to the negative battery terminal.
4 Connect the tip of the probe to the positive battery terminal. Check the probe for voltage reading.
5 Check the Power Probe reading. If your battery is in good condition, the voltage should be between 12.4 and 12.7 volts.

1 “Crank” the engine by turning the ignition until the starter engages and hold for 2 seconds Have an assistant crank the engine while you check battery voltage drop.
2 At the time of the crank, check the reading of the Power Probe. It should not go below 9.6 volts.
- A battery with a volt reading less than 9.6 volts means the battery is sulfated and not holding/accepting the charge.
- Alternatively, you can get the battery tested at an auto parts store or a repair shop.
- They usually test your battery at no charge.
- Home diagnosis is rather difficult and not very accurate.

Do I need to reset the ECU after replacing the battery?

How do I reset the car computer after replacing the battery? I just got a new battery installed but now I’m getting some errors on the dash. How do I reset the car computer after replacing the battery? Great question. To reset the ECU, you can either remove and re-attach the positive terminal from the battery or use an OBD-II scanner,

The first method requires a small wrench to loosen the bolt on the battery terminal. Simply remove the cable and let the car sit for at least five minutes. Then, reconnect the cable and tighten the clamp. Start your vehicle and check to see if the dashboard lights are gone. The second method requires an OBD-II scanner.

Connect it to your vehicle’s OBD-II port, typically located under the steering wheel, You will see error codes displayed. You will then have the option to erase the errors from the system. Then, start your car to find out if the error lights are gone. Note that if you’re seeing persistent error signs after a battery replacement, it could be a sign that your ECU itself has a problem—or that there is an entirely different issue.

Most ECUs are self-learning and should reset themselves after learning that a new battery has been installed.
If you’re stuck, go to a mechanic for diagnostic assistance.

What happens if you don’t code a car battery?

How to fit modern car batteries Today’s batteries need to be installed correctly or the customer may soon need to return to the garage. Without battery coding, the car’s battery management system won’t work correctly and some vehicle functions will cease. The worst case scenario is that the vehicle may not even start.

In this guide, we’ll use Bosch’s ESI 2.0 software to demonstrate the fitting of the battery.
ESI 2.0 is capable of installing several brands of batteries, but the list of battery brands changes by application.
You should fit a battery support unit before starting any work.
This retains the car’s electronic memory.

Without a support unit, the car’s system may reset to the factory default.

It’s important to follow the entire installation process from start to finish, as the coding section of this process can’t be omitted.
Select the correct battery for the car
Connect a battery support unit, such as the BAT490, to retain codes and instrument display information. This should remain connected throughout the battery fitting process

Remove the old battery, ensuring you take off the negative terminal first, followed by the positive one Install the correct new battery, ensuring the positive terminal is connected first and the negative second. If there is a vent tube, ensure it is fitted to the new battery Ensure the battery is correctly located in the tray and clamped into position Plug the Bosch KTS unit to the car’s 16 pin DLC (Data Link Connector) Turn on the KTS unit and select vehicle details manually or via VINlook up Click on the ‘Diagnosis’ tab and select ‘Energy Management’ from the drop down list Select ‘Electric Energy Management System’ in the drop list and press enter

Check the error memory for fault codes. If no codes present, continue to the next stage, but make a note of any fault codes before clearing them and starting the battery coding process
From the list, select ‘Service adaption’
Then select ‘Battery replacement’
You will then see a note on the screen. Please read this carefully
Select the correct vehicle details
Enter the brand of the new battery
Select the new battery ampere hours

When prompted, enter the battery serial number. On a Bosch battery, the serial number can be found on the barcode. This is a 13 digit number, but you’ll only need to enter the first 10 digits

The next screen will display a confirmation of selection criteria. Press continue, then close the programme and remove the battery support unit

Does disconnecting battery clear all codes?

Download Article Download Article Your check engine light typically comes on when there is a problem with your emission control system or another computer-controlled system in your vehicle. The light generates a code that can help you narrow down the problem so you can get it fixed.

1 Buy or borrow an OBD-II code scanner. ” OBD ” stands for “On-Board Diagnostics” and OBD-II scanners are suitable for all vehicles made after 1996. Purchasing a code scanner can be costly, so it’s better to borrow one unless you plan on using it frequently. Some auto parts stores loan out scanners to patrons, or you could borrow one from a friend or family member.
- Note that vehicles made before the 1990s may not have an OBD port under the dash. If they do, it may be an OBD-I port rather than an OBD-II port, so you may need a different scanner.
2 Plug the scanner into the port under the steering column. Modern vehicles have ports specifically designed for OBD scanners. Look underneath the steering column to find the port, then connect the cord attached to the scanner to the port. Refer to your vehicle’s manual if you cannot find the port. Advertisement
3 Turn the key to the “on” position and press the “read” button on the scanner. Put your key in the ignition and switch the vehicle to “on.” Do not start the vehicle. Once the lights on the dash come on, turn off all the vehicle’s accessories, like the radio. Then, press the “read” button on the scanner to access the check engine light code.
- The code will be a series of letters and numbers. Record all of the codes so you can figure out what they represent and make the necessary repairs to your vehicle.
- Some scanners will define or explain the codes while others will not. If you don’t get a definition, look up the code in the owner’s manual or online.
4 Press the “erase/clear” button on your scanner, then turn off the key and disconnect it. Clearing any codes present will turn off your check engine light temporarily. After pressing “erase/clear” and waiting until you see a “no codes” message, you can turn off your vehicle and disconnect the scanner. However, erasing the codes does not fix the problem. If your check engine light comes on, it’s best to take your vehicle to a mechanic to get it professionally diagnosed and repaired. Warning: Once the OBD system resets (which occurs after a few drive cycles or a certain number of miles, depending on the vehicle), the light will come back on if the problem has not been fixed.

1 Remove the negative cable from the vehicle’s battery. Pop the hood and locate the battery. Use a wrench to remove the negative cable, which is usually covered with a black cap and marked with a minus sign, from the terminal. Warning: Erasing codes by disconnecting your vehicle’s battery can also clear out the memory for your radio and other onboard components.
2 Drain any remaining electricity from the capacitor. Press and hold the horn for 30 seconds or try to switch on the vehicle’s lights. Neither the horn nor the lights will work since there’s no power running to them, but attempting to do so will use up any electricity in the capacitor.
3 Wait 15 minutes and reconnect your battery, Leaving the battery disconnected for about 15 minutes will ensure the vehicle systems will completely reset when you reconnect the battery. Secure the negative cable back to the terminal and cover it with the cap (if applicable). Disconnecting the battery will clear the error codes and reset the check engine light.

Why does a BMW battery need to be registered?

BMW Battery Registration App Tool Why Is It Important To Your Vehicle’s Performance? Why is a BMW battery registration necessary? After completing a new car battery installation, it’s vitally important that you register/reprogram/reset the change in the vehicle’s computer system to let it know it’s a new battery and erase its old charging pattern memory clean.

The reason behind this is that the more modern models of BMW now have an incredibly sophisticated electrical system fitted with IBS (Intelligent Battery Sensors), which tailors the charging process to the battery’s type and age.
So, what is involved in the registration process? Whether updating from a conventional lead-acid battery to an Absorbent Glass Mat (AGM) battery or using an OEM battery, it’s vital to register the new battery in the vehicle’s BMS () using an electronic scanner.

This process is known as a new battery registration, which recalibrates electrical components and sensors and erases error codes. The BMW battery registration scanning process resets your vehicle’s charging system and sets the battery capacity to 80%.

It also deletes any stored battery and temperature statistics related to the previous battery.
It’s important to note that your odometer reading won’t be changed or reset throughout the process.
Important Tip: Never replace an AGM factory-fitted OEM battery with a conventional lead-acid battery in a vehicle designed for AGM applications only.

However, you can substitute a wet-flooded battery with an AGM as the new replacement, but don’t forget the registration. For example, if you have a 90AH battery and the scanner only has an 85AH or 100AH setting, always choose the higher AH option instead of, the lower one.

Does my BMW have AGM battery?

Here at Ultimate Bimmer Service we get lots of inquiries about battery replacement, and registration in. Here is some helpful info and guidelines to follow. The important aspects of battery selection when replacing the battery are the physical size, capacity rating, and type of battery. First off it is very important to replace your BMW battery with a battery that is very near the exact same physical dimensions.

This is important due to the fact that the original BMW battery hold-down equipment is designed to work with specific size batteries. The purpose is to prevent unwanted movement/jarring and vibrations that can cause the battery to become internally damaged (shorted cell), vastly reducing the life of your battery.

From a safety stand point in an accident situation a loose 30lb. battery flying around the rear of your BMW can be very dangerous. So please remember it is paramount that the battery is properly secured for safety and longevity in your BMW. Next the electrical capacity rating of your battery is important as modern BMW’s have lots of electrical functions and monitoring systems that are very sensitive to low voltage.

BMW battery capacities are rated in several ways with the most common methods being CCA (cold cranking amps) and Ah (Amp Hour) rating.
Installation of a battery with equal CCA or Ah rating is always recommended.
However if a battery of greater or lesser capacity is installed, vehicle coding is available to correct, but adds unnecessary time and cost to battery replacement.

If a battery of much lesser capacity is used then some electrical functions may be heavily limited, and battery longevity would most certainly suffer. There are some instances where a slightly change in battery capacity will not require coding, please contact us to find out if your BMW and battery choice will be an issue. On to the type of battery which is very simple to determine with factory original BMW batteries, a white battery is a standard lead acid battery, and a black battery indicates an AGM (Boron-Silicate absorbed glass mat). When replacing the battery in your BMW it is best to stick with the factory battery type, but if upgrading to an AGM battery, special coding is available at Ultimate Bimmer Service to correctly retrofit your BMW with an AGM battery.

Long story short on AGM batteries, they hold a charge for longer periods, are almost completely immune to freeze damage, generate almost zero heat during charging and discharging, are very resilient to shock/vibration, will not leak battery acid if punctured, and have very little out-gassing. But are typically 1 to 2 times the cost depending on application.

Contact Ultimate Bimmer Service today to see if an AGM upgrade would be right for you. Now for some information about BMW’s battery registration process. It wasn’t until 2002 when the BMW 745i was released in the US markets that battery registration came about for BMW’s.

Even though it sounds like just some additional paper work, it is not, it is an electrical process handled by BMW specific equipment (GT1 or ISID) connected directly to your car. The purpose is to notify the power management system and intelligent battery sensor that a battery replacement has occurred.

Also the battery charge status, current, voltage, history, and temperature are deleted. Without proper battery registration the power management system does not run properly and can lead to function limitations. Limitations like reductions or deactivations of individual consumer circuits for instance the air conditioning blower, seat heaters, and entertainment functions.

So please have your battery registered it is replaced in your BMW, it is the proper and complete BMW battery replacement procedure to ensure your hard earned money spent on the battery doesn’t go to waste.
On to BMW’s new battery parts warranty policy that was introduced near the beginning of 2011.
BMW no longer offers their excellent 2 year parts warranty on a BMW battery that was installed outside of the dealer.

The main reason for this is that lots of batteries were returned to BMW for an “over the counter” parts warranty by customers/shops that either had other problems causing the battery to fail, incorrect installation (battery hold-down or connections loose), or failure to register replacement.

So unfortunately no parts warranty can be offered by BMW for a BMW battery installed outside the dealer. Keep in mind the dealer typically charges about $215 in labor alone for replacement and registration (1.5HR at $143.5/HR), whereas we charge half if not less depending on model. Thankfully high quality affordable batteries from superior suppliers like BOSCH, and World Source ONE with excellent 24 month warranties, correct fitment/size, and proper capacity are available.

These batteries are proven to perform as good if not better than BMW batteries. Plus with our authorized BMW equipment, and Master Technician’s servicing your BMW at Ultimate Bimmer Service will save you money and get the job done right. On a final note, you can expect your original or quality replacement BMW battery to last 4-8 years in a properly operating BMW, and 5-10 years with an AGM battery.
