Couple things, original battery is an H9 type, the replacement is an H8. The new battery needs to be registered (to tell the car that a new battery has been installed), and coded (to tell the car that the replacement battery is not 105aH).
You need to tell the computer that there is a new battery with a scan tool, otherwise the computer will treat this as the old battery and might overcharge.
As below, you need to register the new battery with the cars BMS or the battery will be overcharged leading to premature failure. Otherwise nice installation video the vent tube on the end of the battery is for any hydrogen discharge that might occur.
I have a 2019 X3 M40i (only 32K miles), but am going on 6 years with original battery, but have had to recondition once because I left the parking lights on (stupid, I know!). I plan to replace it later this year before the next winter season 👍🏻 Cost to replace by dealership is about $550 (with taxes). Well worth it IMHO as this installation process is too complex for my dummy hands.
My 2019 X3 also has a second smaller battery under the hood. It is used for accessories, not for cranking the engine, but it also needs to be replaced at some point.
Your comment was a short winded waste of time. But you chose to spend it by typing on someone’s video in hopes of helping BMW owners. Enjoy your day Hank, I hope there is no time wasted in it for you.
My 2014 X3 purchased in 2013 still has the original battery. I can’t believe that the battery has never failed in the past 10 years and 9+ months.
You are lucky. But I’m sure less electric devices draining it. The BMW connected in the app is probably part of it. Always online.

I also have the 105ah battery in mine - If I replace with an exact OEM BMW 105ah do I still need to code it?
Yes it has to be coded. @@mazz1557
@@mazz1557 yes, the computer adjust the charge to follow battery degradation over time so coding is required

Do you have to update your system or put some type of coding after install of new battery?
yes, you need to register the new battery. he skipped it.
Спасибо за видео, друг !
У нас -27 несколько дней :( и акум разрядился в ноль :((( буду пробовать реанимировать его

Month ago I bought a 2024 X3M40i. Can you confirm that my 12V battery is at the same location? Thank you.

What screw driver we have to use?
Did you of to reprogam the battery
It’s recommended. I did not. Year later and I’m still on this.
Was your vehicle turning over but not cranking when battery was bad
No cranking over. All electronics were just not responding. It had 0 power completely.

This video was a long-winded waste of time.
