Procedure
A BMW battery should only be charged using the jump start connectors found beneath the hood.
- Use the emergency key that can be located within the key fob to unlock the driver’s door.
- Open the hood by twice pulling the hood release.
- Under the engine bay, find the positive terminal.
- Connect your charger’s red clamp to this post.
- Look under the hood for the negative terminal. A marked copper post belongs to BMW. Connect the black clamp to one of the strut tower bolts if you are unable to locate the negative (ground) post.
- the kind of battery to use. On the battery’s top, the type of battery is printed. The battery will either be an AGM battery or a regular/lead acid/flooded battery. It is most likely an AGM battery if the battery has a black case. It is a standard or flooded battery if the battery has a white casing.
- Connect your charger to an extension wire or wall outlet.
- Allow the battery to charge or keep charging. While the battery is charged, do not leave the key in the ignition. It may take up to twenty-four hours to charge your BMW battery if it is completely drained.
The average time it takes for all BMW systems to “sleep” is between 15 and 30 minutes. The battery still loses 0.1–0.5A even when the car is in “sleep mode.”
How to Properly Store a Car Battery
Driving your BMW is the most fun method to keep its battery charged, but what about those times when it has to sit without the alternator’s assistance? If you don’t take the necessary steps, you might not only return to a car that won’t start but also, if it’s locked, there’s a strong possibility you won’t be able to enter it. You should think about how to keep a car battery when it’s not in use to prevent that.
There are numerous factors that could lead to your car resting for long periods of time as the battery drains. If you own a vintage automobile or race car, you may need to keep it during the winter or even just for a few weeks while you’re not participating in car exhibits or races. The same is true for those whose BMWs are only used on the weekends. In addition, an increasing number of individuals work from home, which makes it simple to keep your automobile parked for longer than is good for the battery. There are a few possibilities if you’re wondering how to store a car battery so it is charged when you need it.
How is a BMW charger used?
Connect the black clip to the main charging unit first, then the orange clip, and finally the red clip. Either the BMW battery can be immediately accessed through the trunk or the engine compartment using the red power terminal and the ground to attach the battery charger.
How is a trickle charger used?
Find the black and red alligator clips that are fastened to the charger. Holding the red clip, connect it to the battery’s positive terminal. Make sure the clip is firmly attached to the terminal. It shouldn’t appear flimsy or feel loose.
Connect the black clip to the battery’s negative terminal. Also consider how tightly it is connected. At this time, refrain from touching any portion of the wire or battery. According to Autotrader, the power that will soon pass through the components will give the battery a long life without any shorts.
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.
How long does a BMW battery take to trickle charge?
A BMW’s battery charges after around 30 minutes of driving. The BMW model and year will determine this, although the majority of vehicles will charge the battery in this amount of time. It can take longer to charge the battery if your BMW is older than 2016.
With a trickle charger, is it possible to overcharge a car battery?
A battery charger that delivers a very low voltage is known as a trickle charger. This implies that the battery will charge gradually over time.
Did you realize? It is advisable to charge the battery completely before storing it and to periodically charge it while it is in storage when getting ready to put a battery away for a while. As a result, you will be prepared to use it for your application when the time comes.
As it provides a steady low charge to the battery without significantly increasing the risk of overcharging, a trickle charger eliminates the need for periodic replenishment. It’s crucial to understand the difference between a trickle charger and a maintenance charger.
A trickle charger should be disconnected once a full charge has been obtained in order to prevent overcharging. It will supply a charge at a pace equivalent to the battery’s rate of self-discharge. An ongoing maintenance charger is made to remain plugged into the battery. The charger will automatically turn on and off to maintain the desired charge range after a charge level has been established.
Does BMW refuel its electric vehicles?

How long should a trickle charger remain connected to a car battery?
Some trickle chargers offer a simple long-term battery care approach because your battery can be left connected without risk for several months. Others might be left connected for no more than a few days. Check your trickle charger’s manual for further information.
What distinguishes a trickle charger from a battery charger?
Over 11 years have passed since this article was published. Some information might not be up to date anymore.
We recently purchased a winter residence in Arizona, where we intend to stay for five months. On my subsequent visit, I will purchase a new car—probably a mid-sized sedan—and leave it parked in the garage when we return to Canada. Throughout the seven months we are away, it will remain idle and not be started or run.
Is using a trickle charger still the greatest defense against the batteries dying and subsequent issues with the alarm system, computer, etc.? Gerry, from Cobourg, Ontario
The “best approach” has never been a trickle charger, but happily a new generation of “battery chargers” is available and does the job well.
A trickle charger never stops applying a charge, whether the battery is fully charged or not. This is how it differs from a battery charger. On the other hand, a battery charger has circuitry that continuously checks the battery and only charges when the voltage falls below a predetermined level, preventing overcharging and damage.
A battery charger will start charging again when it detects a reduction in voltage. This enables a battery charger to remain connected continuously. A trickle charger, on the other hand, should occasionally be disconnected and reconnected because it maintains applying a charge; it should likely be used for charging once or twice a month for a day.
There are other precautions you should take before allowing a vehicle to sit for so long, and I would be remiss if I didn’t mention them to you.
Have the dealer or service center change the oil and filter before placing it in storage regardless of mileage as there are no plans to give it some exercise—a 20-mile drive, perhaps once a month.
Before placing it in storage, add gasoline stabilizer, fill the tank with fuel, and drive for 10 to 20 miles.
In an ideal situation, you would raise it on jack stands to prevent the tires from flattening and to allow for air circulation in the garage given Arizona’s hot summers.
How frequently should I trickle charge my device?
If at all possible, after each trip, we advise attaching the trickle charger to the battery. Even while the daily rider might not need to use this strategy, if the battery is being cared for by a smart charger, it won’t harm it. Ultimately, developing this habit will help you avoid spending money and hearing the dreaded “click-click-click” if you failed to charge the battery a few months ago. Browse our variety of motorbike trickle chargers at your leisure, or get in touch with our support team for help making a decision. AGM and Lithium batteries are the two most common battery types used nowadays in motorcycle applications. Before attaching your charger, be certain of the type you have!
How can you tell when a trickle charger needs to be replaced?
Finally, make sure the device is charging properly by checking the display. An amp meter is a common feature of battery chargers; it will read lower to 0 on a fully charged battery and higher on a dead one. Till the charge is finished, keep the battery attached. Here is a helpful video that demonstrates how to read the trickle charger gauge:
There is no requirement to unplug the battery when using a conditioning trickle charger. If you are using a full-power charger, you should unplug the battery.
If the battery is not charging properly, it is crucial to examine the meter. If the meter reads low, your battery may not need to be charged or your ground connection may not be properly secured. When this occurs, you must turn off the charger, unplug it, and then plug it back in.
Your battery is beyond repair if the charger still does not start charging even after a few minutes. You can also try using your trickle charger on a different battery to make sure it’s functioning properly. The charger is operating if there is any movement of the ammeter’s needle from zero. Consequently, your battery is the problem. You can always discover how to tell if your battery is dead in this situation.
