When To Replace BMW Battery?

We advise getting your BMW model’s battery tested at least twice a year and changed approximately every three years to avoid this aggravating situation. However, keep in mind that every battery and vehicle is unique, and that your driving style and the severe winters in New England may have an impact on your battery’s lifespan.

How to repair a BMW battery

If you haven’t already changed the battery in your BMW and don’t know how to do it, here is a quick method. There are nine steps that make up the battery replacement process:

  • Remove your key from the ignition after turning it off. Next, find your battery. In a BMW, where is the battery? The majority of the time, you can discover it within your trunk, either on the floor or on the right side. Located it? The battery liner should be removed.
  • With a 10mm wrench, unplug the negative battery terminal right away, then store the cable.
  • The cable must then be disconnected from the positive battery terminal. To complete the task correctly, lift up the red plastic cover and look for a 10mm nut; you must loosen it.
  • The time has come to remove the brackets. Two brackets, one on top and one on the side, support the battery. First, you should unbolt the latter using two 13mm bolts.
  • Take out the battery from the trunk, but be careful because it could be heavy.
  • Take images of the battery’s model number and technical specifications before you install the new battery. When registering your battery, the BimmerTech expert will need this information very much.
  • Now that the old battery has been removed, gently set the new one in its place. Just make sure the settings are correct.
  • crucial step Secure the battery properly. You must reinstall the brackets in order to accomplish this, being careful not to overtighten them. If not, you could break the battery housing. Connecting a Liquid Lead-Acid battery to the vent house can stop the vent house’s gasses from accumulating within your trunk if you’re installing one.
  • Finally, connect the battery terminals by connecting the positive battery terminal first, then the negative terminal, after cleaning the battery posts with a battery terminal brush.

NOTE: Purchase our Battery Registration service before you ever begin replacing or registering your battery, and choose a preferred date when you could replace and register the battery simultaneously. Make sure you can do everything in one day because battery registration is required following every battery change and needs to be done immediately after battery replacement.

Replacement BMW Batteries: Why Register a New BMW Battery?

Modern, late-model BMW batteries must be “registered” or matched to the onboard ECU for optimum operation and battery longevity, which is a frequently overlooked and underappreciated requirement. You might be asking why this is essential, and some online armchair experts could even argue that it isn’t really necessary and is just a way for the service provider to make more money by replacing the batteries. Some people turn to buying a new battery from an auto parts store, installing it themselves, and quickly learning that their battery needs to be replaced, again, in order to avoid the additional cost of registering their BMW battery.

How long does a BMW battery change take?

A battery replacement can be finished by our BMW service specialists in around 15 minutes. Expect the appointment to take longer, possibly up to an hour, if you have additional services like a brake check or tire rotation booked.

It’s crucial to keep an eye out for these warning indications that your BMW’s battery is starting to fail because it’s so simple to unintentionally drain your car’s battery.

  • Slow engine cranking is one of the first indications that a battery is starting to fail in a BMW, even if the engine starts. Don’t wait until the car’s engine entirely shuts off before stopping. Bring your car into your go-to repair shop right away to get the battery checked to prevent further damage and possible accidents.
  • An examination of the battery is required if an engine won’t start. It’s likely that you need a new battery if your car won’t start at all and you have to ask your neighbor to jump start it.
  • Even though it would seem normal for cars to have trouble starting in the cold, this is actually a sign of a weak battery. Don’t ignore this one. The last thing you want is to be trying to start your car while trying to get home from work in the parking lot!
  • The lights won’t turn on: If the headlights on your BMW aren’t turning on, you most likely don’t have a lightbulb problem. Most likely, the battery is failing. Take your BMW to the local technician to have the battery checked out.
  • requiring a boost: Even if you unintentionally left your lights on and require a jump start this morning, doing so could harm the battery in your car. This can imply that the battery in your BMW lives less than it was intended to. Keep a close eye on your BMW’s battery to make sure it’s in excellent shape and still receiving power from your alternator if you’ve ever had to jump start it.

Does BMW battery programming need to be done?

Let’s first focus on what BMW battery registration genuinely is before delving into the procedure. Battery registration, to put it simply, is the process of notifying your car that a brand-new battery has been installed. Importantly, it must be done every time you replace the battery in your BMW, model year 2002 or later.

The car adapts the amount of energy required to recharge to operate at peak levels as your battery ages and gradually loses its ability to charge. The battery needs more charging the older it is. By registering your battery, you can inform your engine control module (also referred to as DME — Digital Motor Electronics) that a new one has been installed. As a result, the vehicle will reset the old battery statistics and won’t attempt to overcharge the new battery under the assumption that the old one is still in place.

In addition to registering, you must also code your BMW computer. No matter how different or similar your new battery is from your previous one in terms of specifications, it will still be necessary each time you change it.

When should you update the % of your automobile battery?

Then, check the voltmeter reading after having a friend switch on your headlights. 12.5 volts or more at 80 degrees Fahrenheit indicates that your battery is fully charged. A battery is around 75% charged at 12.3 volts. Your battery is less than 25% charged if it reads out at 11.8 volts or less.

BMW has two batteries, right?

Each of them has two batteries. Given that you don’t seem to own an E31, it’s kind of ironic that you titled your piece “You Own,” emphasizing the word.

How can you tell if a battery needs to be changed?

You can start to see your battery reacting negatively to these changes as the North Carolina heat increases. This happens when the heat starts to evaporate the water in the internal fluids of your battery. Corrosion within the battery can also result from this evaporation.

In the winter, your battery’s chemical reaction slows down, depleting its life, and your car needs more energy to start because the engine oil is moving more slowly. A battery nearing the end of its useful life will start to suffer in adverse weather conditions, but newer batteries can handle harsh weather conditions with ease. In order to get your car rolling in the chilly weather and get to a mechanic in time for a replacement, follow these advice.

Can BMW withstand the test of time?

With the right care, almost any BMW has the ability to last up to 200,000 or even 250,000 miles, and there will always be outliers that go even longer. It’s simple to get off to a good start because every new BMW comes with free factory-recommended maintenance through BMW Ultimate Care.

How long does a battery last?

The number of charge and discharge cycles a battery may go through before losing its effectiveness is known as cycle life. The depth of discharge has a considerable impact on the cycle life of Li-ion batteries. The percentage of a battery’s storage capacity that is used depends on the depth of discharge. For instance, a battery with only 20% of its entire energy capacity emptied has a far longer cycle life than a battery with 80% of its capacity discharged, leaving only 20% of the battery’s full energy charge. A typical Li-ion cell’s cycle life is seen in Fig. 6.

How can you determine if the battery in your car is failing?

Connect the positive and negative battery terminals of the multimeter. You can have a faulty battery if your voltage is below 12.6 volts. Start the vehicle now, and check for a revised voltage greater than 10. When the engine is running, if your voltage falls below 5, it is defective and needs to be changed right away.
