Method 1: Examine the battery’s manufacturer’s label.
Typically, all batteries contain labels and other details provided by the manufacturer concerning the battery. So, if the battery’s label is still legible and in good shape, you can quickly identify the type of battery. AGM batteries typically have this information listed on the packaging. If AGM isn’t mentioned on the label at all, you can search online for information on the battery by model number or call the manufacturer and request it.

If you frequently travel short distances for work or another reason that requires you to leave the ignition on, such as to clean the car or wait for someone, I advise investing in AGM batteries.
Compared to standard, non-AGM batteries, AGM batteries are superior at recovering from deep drain. When discharged, AGMs are not likely to sulfate the inside plates.
Most non-M E9x models come standard with non-AGM batteries. AGMs are standard equipment on all E9x M versions.
The car MUST be programmed, and only after that registered, if the battery type is changed from non-AGM to AGM.
Gel, Lead-Acid, Lithium-Ion, or Absorbent Glass Mat?
Lead-acid batteries in the form of absorbent glass mat (AGM) and gel batteries operate similarly to older models. The material that houses the chemicals is different, though, thus the interior is different.
AGM batteries, which allow for quicker charging and more power, are used in the majority of BMW models. Additionally, the battery in more recent BMW models has a computer system that you must register in order for the computer to recognize that you have replaced the battery.
An older battery that has been in service for a year, three years, or even four to five years drains more slowly than a new battery.
Batteries made of absorbed glass mat (AGM)
Lead-acid dry-cell batteries are also known as absorbed glass matte (AGM) batteries. They are thought to be safer than liquid batteries because they are made of glass fibers that form a mesh inside the battery; if the casing is torn, the acid cannot flow out of the battery. They don’t require topping off or any other type of maintenance because they are completely sealed. The simplest approach to determine what type of battery you have is to check it up online by the model number because it might be difficult to distinguish between AGMs and GEL batteries.
What characteristics make an AGM battery?
If the label is damaged or otherwise not very helpful, you can determine the type of battery by examining its construction and design. Basically, the only protruding parts of an AGM battery are its negative and positive terminals, which are always flat on top. On the other hand, AGM batteries are properly sealed, unlike liquid acid batteries, which have a removable top.
Who makes AGM batteries for BMW?
I drove to the nearby BMW dealer today to pick up my automobile. Since I purchased my first car at the age of 16, a brand-new 1974 2002 Tii, I have been a BMW client. I’ve always bought and had my cars serviced at the same dealer, and they’ve always replaced any needed components with BMW original equipment parts, or just BMW brand OEM parts. My oil was changed, and as it should have been, only oil from the BMW brand was used. To my amazement, they inserted a battery from the “Exide” brand when I needed my battery to be replaced. That, in my opinion, is neither proper nor even BMW policy. It would be OK if it had occurred at an independent repair facility not covered by warranty, but what if a BMW-exclusive dealer replaced the battery under warranty with a different brand? I believe I will call the dealer tomorrow and demand they only install a battery made by BMW’s factory. Any opinions on the subject?
Although BMW does not make batteries, a German company does for BMW. These batteries are branded as BMW original equipment batteries and are made for BMW utilizing AGM technology. Exide is not what the automobile comes with, though it may be a permitted alternative. My automobile now has a standard Exide battery that was installed by them.
It’s not a glass mat battery; it’s the original white battery. The enhanced glass mat in black, which is identical to my old battery, is the battery. It is a genuine BMW component. It is a BMW part, if you look at the part number. It’s comparable to pulling out a spark plug and seeing both BMW and ngk written on it.
I’m unable to upload them, however the battery is identical to the black one that the OP posted except that the number begins with a S and ends in 962.
S: 61 21 7 586 962 is what it says. AW is available at 61 21 7 586 975.
It belongs to BMW. Even the factory-applied BMW part number is visible on it. Don’t stress over such a small matter. I understand that nowadays you have to be concerned about individuals betraying your trust and breaking their promises, but this isn’t like BMW. They risked suffering significant commercial losses.
Since you’ve been doing business with the same dealer since 1974, there’s a good probability that they’ll go out of their way to make you pleased.
Most dealers have wet dreams about you as a customer. Maybe the service manager neglected to look in their CRM system. See what they say when you call them.
At least they replaced my battery with a brand-new one instead of the original white one. Since the factory did not send them the 90AH AGM battery, they informed me that they do not have one.
BMW began use AGM batteries when?
BMW began putting AGM batteries in many of their vehicles beginning in late 2002. AGM batteries were later used in several automobiles built around this time that were initially equipped with lead acid batteries.
How durable are AGM batteries, BMW?
The typical battery life of a BMW is 3 to 5 years, although actual battery life might vary greatly based on factors including battery size, weather, battery type, and driving patterns. Even yet, it doesn’t necessarily mean that your battery is performing at its best just because it isn’t fully dead.
How can you differentiate an AGM battery from a GEL battery?
The main distinction between AGM and GEL batteries is that the former only permits partial discharge up to 50% while the latter permits full discharge up to 90%, resulting in a longer service life.
Lead-acid battery types AGM and GEL share many characteristics. However, there are also some distinctions between AGM and GEL batteries. These two battery types both employ valve-regulated lead-acid technology, and both have a propensity to remain free and non-spillable. They differ in terms of their service life and manner of discharge, nevertheless.
To register my BMW, what battery is required?
Battery registration is necessary since all of the more recent BMW models include Intelligent Battery Sensors, or IBS, as they are known by BMW. Are you unsure if your BMW has IBS? This useful guide to model years and particular models will help you determine whether your BMW has to have its new battery programmed each time it is replaced.
- Seven-Series E65/E66 chassis from 2002 and after
- 6-Series E63/E64 chassis from 2003 and after
- 5-Series E60/E61 chassis from 2004 and after
- X5 E53 chassis with N62 engine, 2005 and newer.
- 3-Series E90/E91/E92/E93 chassis from 2006 and after
- X5 E70 chassis from 2007 and after
- X6 E71 chassis for years 2008 and beyond
Which batteries does BMW use?
The BMW auto batteries you use should be compatible with your current model. BCI Group 94 49 H8 batteries are used in the majority of BMW automobiles, including those in the X3, X5, 3, 5, and 7 series. Given that they have nearly identical size, these batteries can also be used interchangeably.
The typical lifespan of an automotive battery for a BMW is three to five years. Your battery’s lifespan can be impacted by a variety of elements, including temperature, battery type, design, specifications, and driving practices.
Intelligent Battery Sensors are a feature of newer BMW cars, particularly those introduced after 2002. To prevent problems in the future, you must register your battery.
You can typically locate the battery and replace it on your own because it is a simple procedure. Just keep in mind that you will need to use a scanner equipment to register your BMW if it is a later model. Additionally, confirm that the new battery has virtually identical specifications to the old one.
Regrettably, you won’t be able to start your BWM if the battery dies. By utilizing jumper cables to link it to a healthy battery from another automobile, you can try jump-starting the battery. The vehicle can be jump-started from the front even if the battery is at the back.
BMW batteries are they lithium ion?
BMW Lithium-ion batteries have the following standout benefits:
- They require no upkeep;
- They are lighter (up to 50% lighter) than AGM or lead-acid batteries;
- They provide more current consumption, allowing for greater state of charge under load;
- With the right equipment, they provide improved cycle stability and higher current consumption, which accelerate charging;
- They can complete 14 times more cycles than a typical lead-acid battery, which qualifies them for use with the intelligent generator control (IGR) and the automated engine start/stop function (MSA);
- The battery life is roughly twice as long as a typical lead-acid battery;
- Lithium iron phosphate cells (LiFeP04) are risk-free because they typically provide less of a threat than other lithium-based batteries.
What is an AGM battery’s biggest drawback?
Comparing an AGM battery to a conventional flooded lead-acid battery, the upfront expense is its biggest drawback. There it is.
Are lithium-ion batteries used by BMW?
Let’s face it: Electrical systems in current vehicles are more important than ever. These days, it seems that one or more control devices must be in communication with one another in order to activate a heated seat, turn on a light, or open a window.
The ultimate limitations of the current 12V electrical system may soon be reached, which creates a significant hurdle for future cars. The likelihood that the battery and charging system won’t be able to keep up increases as we install more electrical devices in our cars and trucks.
In reality, a contemporary premium car like the BMW F30 3-Series may have more than 100 actuator motors and control units, all of which require power (Figure 1). Even with the ignition key off, there is still a sizable amount of power consumption, or “parasitic drain.”
The BMW engineers sought to create a more potent battery solution to address these rising energy demands. This new battery would need to be more powerful, more stable, and have a longer lifespan than comparable lead-acid or Absorbed Glass Mat (AGM) batteries. It had to weigh equally as much as other batteries, if not less, so order to preserve the brand’s reputation for sporty driving.
BMW therefore introduced lithium-ion batteries in its F80 M3 and F82 M4 in the beginning of 2014. Since then, these batteries have “flew under the radar” because they didn’t attract much notice. Both customers and technicians are unlikely to be aware of the type of battery they are using without understanding how to recognize it. Let’s examine this battery construction style and its advantages.
What occurs when an AGM battery is charged using a standard charger?
Lead acid batteries can be divided into two main groups: flooded cells and valve-regulated lead acid batteries (or VRLA batteries). While VRLA batteries have an electrolyte stabilized either either holding it in gel form (gel batteries) or absorbing it in a glass mat, flooded cells have a free-flowing liquid electrolyte (absorbed glass mat, or AGM battery). Because of this, sealed lead acid batteries are another name for VRLA batteries. Although flooded cell batteries are still often used today due to their low cost and capacity to produce a large initial charge, they also need more upkeep, ventilation, and a propensity to lose their charge more quickly.
In comparison to flooded cell batteries, AGM and gel batteries are both significantly more stable and have a much lower discharge rate. Additionally, they require different care than flooded cell batteries, and a charger designed for flooded cell batteries may destroy and kill VRLA cells.
