Connect one of the red clamps to the positive (red) terminal on your own BMW vehicle. Connect the other red clamp to the helping vehicle’s positive (red) terminal. Connect the negative (black) terminal of the assistance vehicle to the black clamp. The other black clip should be fastened to any unpainted metal surface on your car.

Hi. Since the battery is in the back of my 2008 328xi, I assume there are + & – connectors close to the engine. Can someone quickly walk me through the process of using my bmw to jump start a different car that isn’t a BMW? Any assistance would be greatly appreciated.
starting up Two jumper cables can be attached to the battery of another vehicle to start your BMW’s engine if the car’s own battery is dead. The similar approach can be used to assist with starting a different car. Use only jumper cables with clamp grips that are completely insulated. When the engine is running, do not touch any electrically live parts as this could result in a deadly accident. Follow the steps below carefully to avoid damaging either vehicle or raising any safety concerns.

I’ve successfully jumped another car with the BMW jumper studs.
Very effective. Be warned that the jumper cables you buy will likely be of insufficient gauge unless you spend at least $40. Jumper cables often come in 10 gauge. If you’re very patient, 10 gauge will function. After you hook them up, you have to wait around five minutes before using the second automobile. Attempt that again after waiting ten minutes.
Good jumper cables, on the other hand, are 20′ length and 4 gauge. You can jump a car from behind with 20′, which is important if the dead car is parked and you can’t park head-on. Since there is no actual lag in waiting for the dead car to build up a charge, you can link them up and try the dead car right away with 4 gauge.

How to Restart a BMW’s Dead Car Battery
You can use jumper cables and the power from another running vehicle to jump-start a BMW in order to recharge a dead battery. Although the battery is stored in the back of BMW vehicles, you may jump-start them from the front. The red positive (+) connector is located next to the engine and under the hood. You must wait for the battery to fully recharge after starting it before turning it off again.
Can you use the trunk to jump start a BMW?
The fact that jumpstarting procedures for a BMW are remarkably similar to those for any other brand surprises a lot of Greenwich drivers. Although many BMW batteries are located in the trunk, restart connectors are located underneath the hood.
BMW can be jump started, right?
Following the positioning of both vehicles, here is how to jumpstart a BMW: Determine the positive and negative terminals on each battery by removing the covers. Connect the first red clamp to the red (positive/+) connector on your BMW car. Connect the second red clamp to the functional battery’s positive terminal.
Without a key, how do you open a BMW trunk?
Your automobile should include a button with a picture of a car with the trunk open when you’re in the driver’s seat. The trunk of your BMW can be opened and closed using this button. All you have to do is press down on this button to open the trunk.
Can you use the trunk to charge a BMW battery?
My installation is in the trunk. It’s usually preferable to have the charger as close to the battery as feasible when it comes to charging. The negative lead should be linked to the chassis, not the battery, and the positive lead should be attached to the battery terminal.
When jumping an automobile, why don’t you connect the negative?
Shortcuts for Jumpstarting a Battery Never attach the black line to the dead battery’s negative (-) terminal. This could cause an explosion, making it extremely dangerous.
How does a battery charger for a BMW operate?
The supplied manual should always be followed, but I’m utilizing the CTEK on my BMW in this manner. The battery charger features four different charging modes and alligator-style clips. Simply attach the charger’s red and black alligator clips to your BMW, then choose from the Motor Cycle, Automobile, Cold Battery, or Recondition Battery modes by pressing the mode button.
Connect the black clip to the ground and the red clip to the red power terminal. Either the BMW battery can be directly accessed through the trunk, or the engine compartment’s red power terminal and the ground can be used to connect the battery charger.
You can even run the charging cables up through the bottom of the windshield and close the engine bay cover if you don’t prefer to have your hood open.
In a BMW, where is the battery?
The majority of brand-new BMW vehicles are constructed with their batteries in the trunk, unlike practically all other vehicles. Now that we’ve cleared things out, learning how to remove a car battery won’t take much time: Under the upholstery that covers your trunk, the battery is often found on the right side of your car.
Does BMW require a unique battery?
Finding a great BMW battery is one of the most crucial factors to take into account if you want the best for your luxury vehicle. For the best performance on the road, you must purchase a BMW car battery that satisfies the strict criteria of the vehicle.
The 5, 6, and 7 Series BMW vehicles typically have very high features. These automobiles need a lot more energy than your typical car does, thus we strongly advise obtaining them strong batteries.
You must be aware of your vehicle’s needs before purchasing a BMW battery. An Absorbent Glass Matt (AGM) battery is strongly advised for modern BMW vehicles with start-stop technology since it can handle the increased energy demand. However, you can also utilize an Enhanced Flooded Battery (EFB) if you want to buy something for less money.
Just keep in mind that you should only replace the original AGM battery in your BMW vehicle with another AGM. Because these vehicles weren’t intended to be utilized with EFBs, downgrading will cause battery and engine problems with your BMW. On the other hand, if your BMW came with an EFB at the factory, switching to an AGM battery won’t cause any issues.
EFBs outlive ordinary batteries in terms of longevity. They were created specifically for entry-level start-stop vehicles, so they can easily handle the rigorous needs of the majority of modern automobiles.
However, you should always choose an AGM battery if you want to spend more money on a more potent BMW battery. Although these batteries are made for start-stop vehicles, they are also compatible with other energy-consuming vehicles.
In comparison to conventional batteries, they offer a three times longer cycle life and may be utilized in all kinds of weather. Additionally, an AGM battery is necessary if you frequently use the car’s accessories.
BMWs with typical power requirements can be powered by standard automobile batteries. Therefore, if your car doesn’t have high-end gadgets or a start-stop system, you don’t require a special BMW car battery.
Where is the BMW 328i battery?
In the front of a BMW, underneath the hood, is where the battery is located. It is typically found in the car’s engine compartment, close to the front.
Additionally, the battery is typically hidden beneath the upholstery that covers your trunk on the right side of your car. Use your 10 mm socket wrench to detach the negative battery connector from the battery. Next, carefully position the cable so that it won’t come into contact with any metal objects or the other cable.
What serves as an auxiliary battery in a BMW?
I’m aware that this has at least been briefly discussed here previously, but I can’t seem to find any evidence that anyone has ever provided a conclusive response. What precisely serves the second battery that some X3s have installed under the hood? I am aware that some have theorized that it has anything to do with the cutting-edge safety features, etc. My 2018 X3 had NO options, yet it has a second battery beneath the hood. It includes comfort access, blind-spot monitoring, lane departure assist, radar cruise control, etc., but my 2021, which I just bought up Monday evening, does NOT have a second battery underneath the hood. The fact is, it doesn’t really matter in the end. I’m just perplexed as to what that second battery would have been utilized for.
The engine compartment contains an auxiliary battery that helps power the car’s electrical system. The auxiliary battery supplies energy to the vehicle electrical system when the combustion engine is not operating, such as during MSA start-stop.
You might be able to have a smaller rear battery with an auxiliary battery. In the opposite situation, the rear battery could be bigger and store more energy if there was no auxiliary battery.
