My original bmw battery lasted 8 years. Amazing. Started getting fault codes on various things because of low amps. Dealership wanted to run diagnostics for 2 days to figure out what's going on. I put my foot down and said change the battery first. Clear all codes and then we will see. I was right.

When you are tightening up the terminal clamps..especially the negative, it is a good idea to put downward pressure on the engine side of the terminal to counter your tightening torque and minimize strain on the post. You can see in the video at 5:40 the stress on the post.

[@mydimeisup5103]

Good info, I'd say though if you are careful you can get really good deals on batteries. A little over a year ago the AGM battery in my 2013 Audi allroad was starting to die over a couple of days (It was dated 08/2012. AGM batteries are really impressive). A matching H8 battery from VW/Audi was > $250. I was on the Audizine forums and found out an H8 Champion battery at my PepBoys was $189 (including core charge). Installed it last January, changed the serial number by 1 letter with VCDS, and returned old battery and payed 171 for a brand new AGM battery. I've had no problems. I'd say do your research and find a good matching spec battery with a discount and you'll win big time. I haven't had any problems with my battery besides the few times I've left my OBDeleven plugged in overnight.

[@justinbuice]

In my research, I found that most car batteries (BMW included) are manufactured by only a handful of suppliers, so I have no doubt they are all among equal quality/ longevity. I just had a hard time finding something locally.

[@SamFigueroaLeon]

good tuitorial, only thing I'd say is disconnect the negative first then start pulling out stuff and covering the positive. Only way you'd get the old welding arc is going across the terminals... not speaking from experience or anything

[@e90_austin]

94RAGM will also fit these cars. Should be a little smaller but there’s *usually* an adjustment for the bracket that holds the battery in place. All you have to do is register the battery as a lower Amp Hour rating. Won’t affect anything as long as it’s registered to the vehicle. Great video yet again man! I’ll never know why they make these batteries so damn heavy! 🤣

[@Hyytekk]

THANK YOU Justin! Your style of presentation is so clean and concise and your calm friendly manner help remove any intimidation doing a DIY sometimes presents. The 7 year old original battery in my 228i sounded tired. I was going to have a garage pick out and install a new battery for me, but what a hassle just having anyone squeeze me into their schedules. I've always done whatever work I can myself anyway. On your advise I did pick up a BMW battery at a dealer. Also sent for a Carly which I had considered doing for a year anyway for the coding options. I'm heading outside right now so hopefully armed with your insights it will go seamlessly. Appreciate your great instructions!

[@nycshelbygt500]

Justin did his homework. BMW batteries get replaced regularly by new PNs with different specs. These Battery PNs are good for E9X and F3X BMWs. If you are in Los Angeles BMW Parts Pros has a much better price on BMW Batteries. Keep in mind that you can't ship Lead Acid and AGM batteries. Get AGM Batteries in a black case (Lead Acid use a white case). To check the BMW Battery PN Fitment use a Canadian BMW Parts site to show 812 is superseded by E29. HaHa EP AGM Battery 92AH/850 CCA 61212353812 (Old Battery PN - might still be available) EP AGM Battery 92AH/850 CCA 61215A40E29 (Newest PN) The key is that the BMW DME SW only has a few AHr options to select that might not match the BMW or Aftermarket Battery you are installing. So selecting 90AHr is close enough to 92AHr. The DME just stores the mileage when you installed your new battery to change the charging profile for a new battery. Older DME SW doesn't have all future BMW Battery AHr size options.

[@spdrasr3]

FCP Euro dude. I replaced mine in August but found many online. I was lucky needed one very soon and found one at local part store same price you paid. Registered with MHD was easy. Don't forget to return core charge.

[@fstlnj29]

I have never understood the fascination with amp hours. I could be completely wrong but your car either starts or does not. Once it starts the alternator should provide all the power needed to run whatever in the car or they are some crazy voltage paths being taken to charge and discharge a battery at the same time. Amp hours simply refer to how long a battery will supply a certain amperage for how long without a charge. I start my track car with a battery that weighs less than 4 pounds. Of course on a cooler day I need to use a jump box since the oil is thicker but once the car is running and up to temp zero issues for the rest of the day. I saw another video claiming that different things in the car were affected by the battery and its efficiencies. Would love to get an explanation of what and how as once the car is running...again the alternator is doing the work.

[@bl8ze73]

Exactly my concern, I’m looking to swap out the battery on my f22 and I could care less if the car can run alternator-free for 5 hours, I just want a lightweight battery that starts the car (maybe not an extremely small one since I’m daily driving it) but not a massive one.

Hey there is no way to do it through the car’s native menus. Aside from the dealership, any shop that works on European cars will have the capability to do the battery registration, even if you decide to install it yourself.

Hi again, just a note I have talked to a couple mechanics, and they have indicated that its not necessary to register. How can we get the truth on this subject? the thing is that the IBS should track the voltage of any installed battery if it truly is intelligent and no need to tell the IBS or ECU that a new battery has been installed. and how would telling the IBS make it charge differently? some batteries last 4 years and some last over 10 years.

[@wingedhussar5528]

One thing I suggest to do is to check battery voltage while the motor is on, so you can see at what voltage the alternator is charging the battery. There are two easy ways to do this. One is obviously a multimeter, the other is via the hidden menu. To access the hidden menu turn on the car, you can start the motor as well. Press and Hold the trip reset button on your dash till you see a menu come up. If nothing happens just let go of the button and press and HOLD again. Once you are in the menu keep pressing the reset button till you get to a menu item called Unlock. Now press and hold again. You will then see some 0s come up. Now add the last 5 digits of your vin and press the button until you see that number. In my 228 the total was 16 and in my 440 it was 18. Once you have the correct number selected press and hold the reset button again and you will be taken back to th3 menu screen but now with way more options. Push the button till you see Voltage and hold it. Now the exact voltage will be displayed. For the 2 series drivers you can also get drill down to the Temperature menu and see what your oil temps are as well as coolant. This is useful since the 2 series dash does not show oil temp. Next with the motor running and the voltage menu up, turn on the rear window defroster, and put the ac on max. Look at the voltage and if the battery is starting to go bad it will likely be at 15V. This is important to know because once you register your new battery the voltage with the motor on (alternator running) should not be hitting 15v. Once you install the new battery and register it run this test again. In my case i had to register it twice with the Carly app before it took.
