Hi,
Since I barely drive the car every other week and even then, the trips are only a few miles long, I’m looking for advice on how to recharge my 118i convertible battery.
I’ve read that you can charge it from the engine bay posts, but I was curious whether I could lock the car while the charger is still in place and charging.
It is acceptable to lock the car while it is being charged slowly. Since the majority of cars feature Comfort Access (CA) and the car needs to “go to sleep” in order to have the least amount of draw on your car’s battery, it’s actually best way to charge in.
Under the hood, there are connection points. However, most reliable chargers also allow you to hardwire the connectors at the battery or underneath the hood.
I’d heartily advise getting a CTEK device. My purchase cost me roughly 60 euros on eBay. A trickle charger is necessary, but a device like the CTEK won’t overcharge the battery and damage it. The battery will be “cycled” and “conditioned” by the CTEKs. Really, it’s worth it.
Despite the fact that I own two Deltrans, I told my son to get a CTEK, but after roughly ten years of moderate use, the Mode switch failed. We were able to solder in a replacement after finding one. I can’t recall right now, but the new switch has a minor problem.
For approximately 15 (lead acid) and 10 years, the Deltrans have been in use throughout the winter. Additionally, I could suggest Schumacher.

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.”

Are you genuinely claiming that a phone charger can be used to recharge the booster? More likely, the booster can be used to charge the laptop or phone. Most phone chargers and other portable devices have 0.5a USB outlets, while most have 2.1a USB outlets.
Yes, you can use a phone charger to charge it. It can be charged either as “quickly” as the 2.1a USB interface allows or more slowly. It takes 3 hours to charge at 2 a, but 12 hours at 0.5 a. Additionally, you can use it to charge other gadgets via USB.
I still believe that most solutions are one-hit wonders; you use them once to get you out of trouble, then you forget about them, and the next time you need them, they’re useless. It would be better to mount a charger to the vehicle’s battery and use one of those charged devices to start the vehicle and charge the vehicle’s battery. Particularly in a BMW, as the car is likely to shut down accessories like the cigarette lighter, which typically “keeps” this kind of booster topped up, if there is any problem with the battery or charging circuit.
Jump leads never “grow old” (at least not in the sense that they cease retaining a charge and eventually stop operating), cost nothing, and as long as you’re north of Watford, someone will always come to your aid. To each his or her own.
How come my BMW asks to charge the battery?
When your battery is below the recommended state of charge, your BMW may issue one of three degrees of warning. Level 1: The car appears to be functioning normally, but there is a caution message that reads, “Charge Battery.” NO servicing is required at this time; this is merely a notification.
How long does it take a BMW automobile battery to charge?
typical charging times for a BMW i4 Level 1 Charging (120V/1.2kW) takes about 100 hours to charge from 0% to 100%. Level 2 Charging (240V/11kW): 8.25 hours to reach 100% charge. DC/Level-3 Charging Fast Charging (195 kW): Charges from 0 to 80% in around 31 minutes.
How do I charge the battery in my car?
Observe the directions for the charger you have. The most common chargers’ basic instructions are as follows:
Connect the charger’s positive cable to the battery’s positive terminal.
Connect the charger’s negative cable to the battery’s negative terminal.
First switch off the charger before removing the positive and negative cables.
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.
Can I change the battery in my BMW myself?
Do you not adore your BMW? And you intend to continue using it for as long as possible, right? Change your oil, replace your air filters, and do other routine maintenance on your BMW as needed to ensure its longevity. Maintaining the battery in your BMW, however, is the one item that contributes the most to flawless operation of your vehicle.
However, a lot of individuals ponder whether BMW battery replacement and registration are straightforward do-it-yourself tasks or require the services of a qualified specialist. We affirm that you can manage the replacement on your own. However, if you lack computer literacy, let us handle the registration process on your behalf.
Here, we’ll go over how to install a battery in a car, examine BMW battery registration in further detail, and provide additional information on the BMW battery reset process.
How long does a battery from a BMW 1 Series last?
You might be curious about how frequently to change your car battery to guarantee the finest performance around Corona, whether you own a brand-new BMW or an older model. A BMW battery will typically last three to five years.
What occurs when the battery in a BMW is low?
After you turn off your BMW, your battery continues to run for a while. After you leave, it will continue to run your radio, lights, clock, and even the security alarm for the car. Electrical issues with your BMW could cause some components to turn off while others, like your lights, remain on, draining your battery. When you leave your BMW, make sure all electric components are turned off.
My BMW battery is it AGM?
With factory genuine BMW batteries, it is quite easy to identify the battery type: a white battery denotes a conventional lead acid battery, whereas a black battery denotes an AGM.
Why is the battery in the trunk, BMW?
Instead of the more conventional engine-bay-mounted battery, the majority of BMW vehicles use a trunk-mounted battery. Because of the constrained engine bay space (a powerful engine must fit into a tiny space) and the need to maintain a weight distribution that is as close to 50/50 as possible.
How long does it take a 12 volt charger to charge a car battery?
A 12 volt charger will take roughly 12 hours to fully charge a car battery because they typically store 48 amps. An electric car needs about 30 minutes to charge to 80%.
Does the battery need to be driven in order to be charged?
As was previously said, whenever the engine turns the belt connected to the alternator, the battery in a car will charge. Yes, a car battery will charge while it is idle if the alternator, engine, belt, and battery are all in good condition.
There is only one restriction: It doesn’t actually “charge” that quickly. This is due purely to the engine’s lack of a load while your car is just sitting still.
Additionally, the RPMs when the engine is idling are lower than the RPMs when the vehicle is moving. As the shaft rotates more slowly due to the belt’s slower rotation, less electricity will be generated to recharge your battery.
Still, the battery needs to recharge more quickly than it is using electricity. When your car is idle, consider all the electrical systems that are in operation:
- a radio
- AC unit
- fuel pumps
- boards with computers
Your battery will continue to lose charge if the power required by these components exceeds the supply provided by your alternator. Although it’s technically still charging, too much electricity is being used.
For this reason, if you’re trying to recharge the battery in your automobile, I typically advise against just idling. Other methods of charging it exist.
