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.”

Every time I start the car lately (perhaps due to the cooler weather), I get the notice “increased battery depletion.” I drove my 2014 X6 to the dealership when the same thing happened during the winter, and I was told that the battery is OK and keeps its charge. Because the message remained gone for a few months until lately, I assume they must have charged it as well.
I believed I merely needed to charge the battery because I don’t drive large distances, just a few little journeys throughout the day, and the car was sitting in the garage for two months while I was abroad.
I looked in the handbook, found the terminal under the hood, connected the charger, and then a strange thing occurred.
Black & Deck brand charger initially indicated that the battery was only 25% charged; however, the battery went from 25% to 100% charged in less than 10 minutes. The device would stop charging after that.
Nevertheless, every time I started the car, I experienced “increased battery depletion.”
I reasoned that the shoddy 15 amp Black and Decker charger would not be able to charge the battery in just 10 minutes, so I purchased a NOCO Genius charger from Amazon, which is totally mechanized, automated, etc.
That one worked better; after charging for about 20 minutes (and with an initial charge of less than 25%), it indicated that the battery was full before quickly beginning to recharge again, displaying successive percentages of 25%, 50%, 75%, and 100%. After letting it run for two hours, the “increased battery depletion” was really helped.
However, if I understand correctly, the charger should simply keep the battery at 100% after it has been fully charged. I think something is wrong with the charger, the way I use it, or the battery. This is a new issue for me.
Your car likely has AGM batteries, just like mine does. They occasionally disagree with common battery chargers. I employ CTEK chargers, which are designed exclusively for AGM batteries.
you might even have two batteries. Unsure of their specific wiring and whether they are both directly charged when connected under the hood.
On my last 4-5 BMWs, I utilized the BMW-branded charger, and it performs admirably. I connect my car to the charger if I know I won’t be driving it and sometimes as a once-a-month prophylactic step. Our 2017 M6 displays the Increased Battery Discharge warning if it sits for days without use, however my 2017 X5 40e and now 35d never have:-O
This topic is interesting to me. I had no idea there were battery connectors for + and – under the hood. With my compressor, which connects directly to battery terminals and uses alligator clips in place of the cigarette lighter port, I can now fill up my tires, blow up inflatable things, bicycle tires, etc.
For several years, my E60 has displayed the same “increasing battery discharge” notification. BMW has consistently insisted that there is no problem. I mostly take short journeys. The notification disappears after a few longer journeys but immediately reappears. I’ve never used a charger before.
If the unit discharged and the trunk was blocked, how might access be gained?
We use the following expert’s response as the answer:
You will require a connection to the vehicle’s electrical system in order to open the trunk or recharge the battery. For this, the BMW X5 has unique terminals (pins) under the hood where you can attach the external power supply (for lighting up). The terminal + is placed closer to the back of the engine compartment and is covered by a red cap with the sign + on it. They are situated on the left side of the direction of motion.
The terminal denoted by the sign “–” is either one of the large-sized nuts on the left rack or it is marked separately on the left fender liner. More information is available in the manual. The car can be opened and the battery refilled or changed after the power is connected.
How long does it take a BMW X5 battery to charge?
On battery power alone, the larger battery in the 2021 X5 plug-in hybrid is predicted to travel around 30 miles. The X5—then known as the xDrive40e—was only capable of an all-electric range of 14 miles from 2016 to 2020.
The increase to 30 miles is significant since it enables many commuters to drive all day without using any gasoline. The “Electric” mode on the X5 makes sure that the gas engine is shut off and that the electric motor is driving the wheels instead.
According to BMW, a full charge using the 3.7-kilowatt charger for the X5 xDrive45e takes little under five hours. This assumes the use of a powerful Level 2 home charging station that operates at 240 volts, such as the JuiceBox 32. The xDrive45e will increase range by between six and ten miles per hour of charging, depending on a number of variables.
Long-distance road excursions can be completed by drivers in plug-in hybrid vehicles with only a few brief gas fill-ups. The X5 xDrive45e has a more than 500-mile range.
On the other hand, short daily commutes of up to 30 miles can be entirely electric. Additionally, using the JuiceBox 32 to plug in for a few hours would significantly increase the daily electric range for commuters who have access to daytime charging.
Can I use a Tesla charging station to refuel my BMW X5?
You do not need to be a Tesla owner to only charge your vehicle at the Tesla charging station, to give you the quick answer.
How quickly can a BMW X5 45e be charged?
The X5 is clearly no wimp, especially with its weight coming in at over 5,600 pounds, with 389 horsepower and 443 lb-ft of torque. The inline-6 is a great engine that feels lively enough in almost any driving situation, and the adaptive air suspension performs admirably. It absorbs bumpy roads with smooth, quiet prowess when in comfort mode. For a car of its size and weight, it corners nicely when switched to sport mode and starts to purr.
Because the exhaust noise is very subdued, I bring up the purr as opposed to a roar. Although I doubt many people would object, I had hoped for a little bit more growl from a vehicle sporting “M” badging, even if it was just the M Sport variant. But the M brakes are excellent, and the xDrive system instills confidence in every type of driving we tried. The ABS is also well-tuned, and the M brakes are excellent. I even put the suspension on its highest setting and took it on a rough trail that had some snow. Breakover angle was quite spectacular, and I may have never felt more at ease on a trail.
Although the steering feels a little disjointed and isn’t my favorite, the paddles are enjoyable to use and the ZF 8-speed automatic transmission responds quickly to them. Even when manually shifting, you can hold the redline, which is something many other cars won’t let you do with full control.
The issue of electrification, which has advanced significantly since the previous generation, is the big one. Although only roughly 17 kWh of the battery’s more than 24 kWh are currently in use, it now houses one. Although the car only has 111 horsepower when in full electric mode, the low-down, around-town torque is still outstanding. BMW advertises a 31-mile electric driving range, and we frequently met or even exceeded that claim. This might offer a mostly electric driving experience with a beautiful engine to provide backup, depending on your commute and lifestyle. When driving in electric mode, you can press the accelerator pedal all the way down, hitting a “false bottom” when the engine’s maximum power is reached. The kick down option allows you to kick through the floor, which will start the engine and, more or less, tether you to your seat as the beast awakens.
The charging process is where I observe the most performance flaws. The 45e can charge at a maximum rate of 3.6 kW, which takes about 7 hours to fully charge the battery from empty. It might work for you if level 2 charging is available at one or both ends of your commute. However, if they are in a rush, many people can find this frustrating. Although it can keep the battery charged while driving and use it later, combustion engine efficiency will undoubtedly suffer.
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 large is a BMW X5’s battery?
At least in terms of day-to-day driving, a larger battery might be a more meaningful change. The battery pack currently has a 24 kWh gross capacity, of which 17 kWh are usable. This makes the X5 xDrive45e exceptionally competitive with other plug-in hybrids of a same size and price with an EPA-estimated 31 miles (50 km) of range when simply using the battery and electric motor. Additionally, the X5 xDrive45e can now travel at 84 mph (135 km/h) as opposed to 75 mph (120 km/h) in electric-only mode.
In actuality, the EPA’s assessment of the electric range is a little bit ambitious, but as long as you operate the X5 xDrive45e in Electric mode carefully, 25 miles (40 km) sounds plausible. As long as you keep the car in electric or hybrid mode and the most of your excursions are brief, it’s conceivable to spend a few days between charges and hardly ever hear the internal combustion engine start. The SUV is able to move quickly alongside other traffic despite the electric motor’s output appearing to be modest in practice. This serves as yet another example of the advantages of electric motors and their near-instant torque delivery. Advertisement
Be ready to wait when you do need to plug in once more. While connected to a Level 2 (240 V, AC) charger, the X5 xDrive45e is only capable of 3.7 kW, even if the charger itself has a higher power output capacity. It will take a little more than five hours to fully recharge the battery pack. That’s not really a problem if you simply plug the car in at home each night, but if you intend to recharge at the grocery store, it does mean you’ll need to spend a lot of time shopping.
