You love your BMW, don’t you? And you want to keep driving it as long as you can, right? There are few things your BMW will require of you to maintain its longevity then — changing your oil, replacing air filters and other general service tasks. But one thing that does the most to ensure your car will run smoothly is taking care of your BMW’s battery.
Many people wonder though, whether BMW battery replacement and registration is a simple DIY process or has to be done by an expert technician. We say: you can definitely handle the replacement on your own! However, when it comes to the registration — if you’re not a tech-savvy person, let us do the work for you.
Here, we’ll explain how to put a battery in a car, take an in-depth look into BMW battery registration and tell you more about the BMW battery reset procedure.
Conventional wisdom when it comes to choosing your new battery goes that the perfect replacement battery would be the one with very similar specifications to your old battery. Hence, it should be of a similar type and capacity.
Our registration process frees you from that necessity. BimmerTech specialists offer a coding process to adjust your vehicle to the new battery specifications. You’ll hear more about it later in the article.
Those who prepare for a battery replacement often ask: How do I know if my battery is AGM or GEL or Liquid Lead Acid?
It’s vital to know which type you are using, as each of them needs to be handled differently. Making a mistake may lead to shortening battery’s life or harming the driver.
So to get things straight, Liquid Lead Acid batteries have so called flooded or wet cells — the regular and most popular lead acid battery type. You can identify them by the caps on the top which you can open to fill the battery with distilled water.
GEL Lead-Acid batteries are on the other hand dry-cell batteries, as they contain an electrolyte in the form of a gel. Plus, they are fully sealed and have noticeable flat tops with no signs of caps or filling ports on them. How to see the difference between a wet-cell battery and a gel battery? You can either check the label or shake the battery. If it’s wet, it’ll continue to move around inside after you stop shaking. If it’s gel-filled it will stop.
Absorbed Glass Matt (AGM) batteries are also lead-acid dry-cell batteries. They consist of glass fibers creating a mesh inside the battery, which is why they are considered to be safer than liquid ones; if the casing gets damaged, the acid can’t leak out of the battery. They are fully sealed and don’t need to be topped off or maintained in any other way. It may be tricky to differentiate AGMs from GEL ones, so the best way to tell what kind of battery you have is to look it up online by the model number.
If you didn’t already replace the battery in your BMW and don’t know how to put a battery in a car here is a fast way to do it. The procedure of battery replacement can be divided into 9 steps:
NOTE: Before you even start replacing or registering your battery, purchase our service of Battery Registration and set a preferable date in which you could replace the battery and register it at the same time. Battery registration is a must after each battery change and has to be handled right after battery replacement, so make sure you’ll be able to do it all in one day.
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.
Apart from the registration procedure, you also have to code your BMW computer. It’ll be necessary each time you replace your battery, no matter its specifications - whether your battery is similar or extremely different from your old one.
The electrical system of BMW models manufactured after 2002 got very sophisticated, as it started to adjust charging to the age as well as the type of the battery. If you’re changing your BMW battery for a new one having different capacity or type, your DME has to be updated with this info. It happens for example when you’re switching between batteries with lower and higher cranking ampere ratings or swapping a Liquid Lead Acid battery for an AGM battery.
Registration is required so that your car knows about the changed specifications and can adjust to the new battery settings. Otherwise, if you don’t properly reprogram your battery, it could result in many electrical problems; you could overcharge or undercharge your battery, or in the worst case scenario, cause considerable damage to your vehicle’s alternator and electrical system — at this point your battery may fail prematurely.
All BMW models manufactured after 2002 require battery registration, as they are significantly more advanced in terms of electrical environment, which aims to improve the gas mileage. Models developed since 2002 are equipped with the system of Intelligent Battery Sensors (IBS) that contains micro processors monitoring and measuring charge, discharge, voltage, current and battery temperature.
