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.

Your car’s battery is there for a very good reason: it supplies the first power required to start the engine and move the vehicle.
