The answer is obviously going to be market-specific, but what ever you end up with, besides meeting the stated electrical and cranking requirements, make sure its a AGM-type battery.

Advance Auto parts sells a good H9 AGM battery, and they always have coupons if you order online and pick up in the store - I paid about $140 two months ago.

I got this one from SAMs club

Why do you need to register and program a battery? Can most places that sell and install batteries do that without having to go to the dealer?

From what I been reading the charging system is so advanced it adapts to aging batteries. Registering lets the computer know to reset the adaptation process. The ECM also needs to know what CCA/AH AGM ECT. for the charging system to charge correctly. There is some controversy on registering if replacing the battery with the same CCA/AH. I decided to stay with the same battery and buy a scan tool that can register the battery myself. The scan tool just paid for itself with the money I saved by having the dealer register the battery for me.

I would believe NONE of the battery replacement places can register a new battery.

The (original) battery in our F25 X3 was replaced in November. The battery was supplied and installed in my driveway by the local roadside assistance group (called the RACQ here in Queensland). After the battery was installed, pulled out his laptop computer, connected to the car via the port in the drivers-side foot well, and reset the system to recognise the new battery. No visit to a dealer required.

Will obviously vary according to market but I wouldn't rule out the possibility that battery suppliers can reset the system.

Following....typically how long is the factory lasting in the X3s.

My battery is original from Feb, 2012. So coming up on 6 years. It seems like mine will need replacing anytime soon. My car has been garaged when not in use all the time except for 3 months during the winters. I have AAA roadside assistance Plus so I'll give them a call to see if they can do it. Otherwise, I'm out in Salt Lake City so it may have to be the dealer if it happens here. Not sure what they charge but I've heard about $400-$500. Geez....it's just a battery!

Our original baterry was replaced after nearly 6.5 years. Quite impressed with that.

I also bought the CTEK 5.0 smart battery charger/reconditioner. After I replaced the battery I put the charger on my 7 year old battery and it passed.

Big Kid, Where did you get a scanner to reprogram your battery? I just talked to the dealer and they told me it would have to be reprogrammed by the dealer. They want an obscene amount of money to replace a battery and or reprogram one.

It was on sale (149) during the holidays. If you sweet talk them they might still honor that price.

Also, I don't think it can change the type of battery so get the same type battery and register.

Hey mate I've gotta do likewise and change the battery in my 2013 X3...how much did RACQ end up charging? I think they give 25% off for batteries so I may as well join them and get them to put one in.

[rirrgang]

I had our local AAMCO shop, that does all my work on the X3, replace the battery. For $230 I got a new battery and they registered as well.

I ordered mine directly from the manufacturer (Odyssey). Their batteries are pricier than most but they seem to make a solid battery with a great track record: https://shop.odysseybattery.com/p/49-950?pp=12

Info on the battery line: https://www.odysseybattery.com/Batte...signAdvantages

Decided to put most money on the battery itself so installed it myself and registered it using Carly.

According to RealOEM there are a few Genuine battery options (at least for my 2016 X3 35i):

Original battery:
https://x3.xbimmers.com/forums/showt...hlight=battery
80Ah 800CCA

Other battery options:
https://www.realoem.com/bmw/enUS/sho...diagId=61_5704
92Ah
105Ah

It appears that the 105Ah is the least expensive on getbmwparts.com. Are all of these AGM batteries?

I have BMW ISTA to configure/register the battery.

It's not clear to me why any H8 AGM battery would not be a suitable replacement. It seems to me that a H8 purchased from Costco, Walmart or Sam's Club for less than $150 would be no different than a BMW branded one. While it's recognized that these must be programmed, is there any reason why generic ones cannot be? The European car manufacturers appear to be masters of turning generic consumable parts into proprietary profit centers.

So the replacement Genuine BMW batteries are not that much more expensive than aftermarket ones.

I believe they are $160-180 thru getbmwparts.com.

However, I think the issue I might have run into with other batteries purchased elsewhere is that Ah rating may not always be printed on the exterior of those batteries. ISTA needs to know the Ah rating of the battery if you're programming for a different battery.
