In this video, I replace the battery in my BMW F30 340i. It was surprisingly difficult to find the correct battery for my car. The original part number had been discontinued, there was little to nothing in stores or online with matching specs, and information on the forums was contradictory or incorrect.
Luckily my local dealership had the battery in stock and it wasn't much more expensive than the batteries at the auto part stores. I wish I had just gone to the dealership first and saved myself the time and frustration. Keep in mind there is still a HUGE savings if you install and code it yourself rather than having the dealership install it. You will pay almost double if they install it for you.
If you're physically able to replace your battery at home (I'm not kidding, this sucker is HEAVY), you'll need to register the battery to let the car know that it has been replaced. I used Carly, but BimmerLink will work too. If you use BimmerLink and need to change the amp hours, you will need BimmerCode as well. With Carly you can do both in one app.

ONE LAST THING: there is a small white plastic plug on the opposite side from the vent tube. You’ll need to transfer that from your old battery to you new one

[@markshaulis]

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.

[@M3BEATS]

Nice video Justin! Glad you were able to get it sorted out. It took me a while to figure out my battery was the issue but once I replaced it the starts and everything back strong. Good job!!!

[@DxApollo]

Just wanted to say this video helped me so much. I went to my dealer and got a new OEM battery for 250$ and registered it myself. Thank you!

[@parthdinubhai]

The attention to detail in this video shall not go unnoticed! Great job Justin!

[@justinbuice]

I appreciate that!! A lot went into this 😅

[@nofilter2091]

Great video and explanation of WHY you need to register your battery- many people have roasted their batteries because they didn't know they were supposed to do that. Also, that specific CTEK Battery Charger is a very good one, I have it too. It even comes as an OEM stock part with many higher-end cars, it's a very good investment.

[@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!

[@justinbuice]

Glad I could help and good luck!!

[@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! 🤣

[@MrEye4get]

Another great video! Handles on a battery in that location are essential! If the replacement battery doesn't have handles, consider using tie straps or two old belts!

[@Fungustus1]

Super good job on this video! It's chill, informative, and super good production quality. Also helped me out a ton, so thanks!

[@justsomecanadian]

That's interesting, the stock battery in my 340i is 900CCA and manufactured by Banner of Austria (OEM supplier), I'm guessing the slightly higher CCA on mine is because it's a Canadian spec vehicle- although where you are it gets pretty cold too! ❄️

[@Paula-xo5bb]

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.

[@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.

Hi Justin, That was a great video. I am told that the batteries on most BMW’s sold in India have a 15 volt battery and car’s software is lost w hen you remove the battery. This would mean that the software needs to be re-installed. Would you have a video on the latter?

I own a CTEK 7002 US, 7-amp, charger that I have owned for about 10 years. I use it on just about all of my vehicles. Sooo, the question becomes that someone said you should use a minimum 10-amp charger. Your thoughts? OBTW, I really appreciate your instructive videos!

[@rebelreviews2464]

I love the Flex!!!!! just wave the foot and the trunk opens lol

[@justinbuice]

😆

[@MiccaPhone]

about the ctek charger: don't I have to disconnect the battery from the car each time before charging it? this makes it quite impractical, as I have to remove the coverings in the trunk each time and have to re-adjust the time and maybe other settings after reconnecting the battery to the car - quite tedious and time consuming... Or are there chargers that don't require disconnecting the car?

[@brendatrimble3433]

I was reading info on battery replacement in my 2016 3X F25 BMW and it said that the power can't be interrupted and to use a tool made to be plug in until the battery is installed so that none of the settings or data will be lost. I noticed you didn't mention that and wondered what your thoughts were.

[@jorgemartinbg]

Hi, I had removed my battery and then had a recharged only for the car to basically discharge it. So I had it recharged again and I saw your video about the Carly app, so I’m gonna go ahead and purchase that, but what should I put on the setting because it’s not a brand new battery even though it was recharged. It’s supposed to be 900 cca but after the recharge it’s 521 cca , I wonder if it’ll go back to 900 once I run the car for 30 minutes after doing the procedure from 6:09 . The car had been standing still for a while and I had to remove the battery because I was fixing something.

My 340i is a 16 btw….so I will need a battery like you. Assuming the 16 battery is same as 17? I hope you can charge our batteries from under hood terminals! Idk….but I did it.

A little help Justin: I like your upgraded 340 BMW and I'm in a similar situation. Currently I have the 2011 328i and I'm looking to upgrade in the next year -- what would you suggest? I like my 6 cylinder non turbo, and I like that it's 4-door. Buying used of course, any good alternative come to mind based on what you've seen at shows or wherever? Great video mucho thanks!

[@justinbuice]

Hey, all F generations 3 series are turbocharged now, whether you get a 4 cylinder or a 6. I don't have any personal experience with BMW's inline 4 cylinders, but some of them have known timing chain issues. Personally I'd be looking at either a 335i or 340i, both of which have single turbo inline 6's. F30 335i's have really come down in price, especially early model years (2012, 2013).
