My point is that all H8 AGM batteries are very similar whether a genuine BMW battery or not. I suspect that one can research the Ah spec. For example, I found that number for Interstate, Delco and Diehard batteries online. However, another issue might be the warranty. Most premium OEM batteries have 3 - 5 year warranties, is that the case for a BMW one ordered online?

Hi chaps, to avoid opening another battery replacement/registration thread, I thought I'd hijack this one.
I have a 2012 X3 F25 2.0 diesel and I am getting frequent charge battery messages. At one point we had to call out AA to jump start us. The battery is original, so is 8 years old now. The battery is 90Ah/90A/900CCA - what is the best replacement for this? Most battery sites in UK give me different options with varying specs. Some overspec, some under. This is all rather confusing. Also, I am looking for something that's, as well as reliable and won't break the bank, easy to register (I have ISTA/D/P). Am I right in thinking that I have to code as well as register if it's not an exact original? |

There are actually not that many different battery manufacturers (at least this is true in the States); many many brands but only made by handful of manufacturers. Stick to a name brand - (First Interstate, BOSCH, etc.) and you should be fine. You have the tools to do the 'registration' so you're set. |

Thanks for the link - handy to have!
Yes, I am trying to find the most like for like but for example, 95Ah batteries seem to have 850CCA vs 900 that's stamped on top of mine. I can't actually find any 90Ah/900CCA ones, hence the question. Also, the price difference between various brands can be quite large. For example, Lucas, which makes a lot of OEM parts battery is £140 but the same specs Varta is £190. |

An X6M garaged all winter...was left out one night...-10C or so..the next morning a little slow to turn over, and an "Increased battery discharge" advisory. The battery (OEM) was new Nov 18. Last edited by Bilbofraggins; 02-23-2020 at 04:57 PM.. |

Blimey - but we don't get those temps in the UK. My battery was original from 2012, so it was expected to go.
In the end I just replaced with an official BMW battery as it wasn't much more expensive than a good brand equivalent. All OK so far and stop/start started working too! |

Second this, I thought for sure after 7 years the battery in my 335 was on it's last leg but a year later it's still going. Was going to replace with a Deka, as I have a hook up to get them at cost. Plus have heard nothing but good, they are very popular in the Corvette community and very close to BMW battery specs.

that costco battery seems kinda pricey. I believe you can get an oem one for mid 150s https://www.getbmwparts.com/oem-part...ca-61212353814 if you want something local, pepboys is doing a 25% off sale on most agm batteries. I recently bought , installed, and registered this one: $149.99 https://www.pepboys.com/champion-agm...roduct/2071679 |

Is physically fitting a non-BMW branded battery an issue? I note that some in this thread suggest an H9 battery while others mention an H8. The dimensions of these differ from one another and also with the BMW battery. The mounting brackets would accommodate fractions of an inch in every direction, but has there been any problems bolting in an H8 or H9 battery?
As I recall, a 2001 Volvo V70 I once owned also had an odd sized battery, but a standard sized one could be substituted if the bottom mounting bracket was drilled out (so as to secure the smaller battery case). Would a similar mod be necessary in the BMW? |

Is your Champion an H8 battery? Also, from the side-by-side photo, the new battery appears slightly wider and longer (and possible taller), however, that might just be perspective. Nevertheless, it does seem to fit very well. Thanks

the battery was identical to the oem in size. the camera angle does make it appear larger. link to the actual batt: https://www.pepboys.com/champion-agm...roduct/2071679 (as of today, $149.99 due to 25% off sale) |

Yes, COSTCO's little pricey. Bought a 95Ah, no 105Ah available. Haven't installed it, am thinking about registering this 95Ah as 105Ah without coding: https://www.bimmerfest.com/forums/sh....php?t=1372943 |

FYI in Canada I bought my 105 Ah AGM battery at Canadian Tire of all places. Only place I could find it other than from the stealer.
The 105 Ah battery is about 50% longer. Its the biggest car battery I have ever seen. |
