2024年1月21日 · And yes, replacing the auxiliary battery sucks in that version of the car. For reference, if the main battery in the trunk is a 105Ah - It is BMW part number- 61 21 5 A40 E33 (105Ah AGM H9 size battery). $245 + Tax = $263 for the battery + $18 refundable core charge from my local BMW dealer / service center.

2013年10月14日 · Late model BMW charge their battery (alternator out put voltage HIGHER than battery no-load voltage) ONLY on overrun. Otherwise the alternator is supplying only accessory loads. A BMW will NEVER EVER fully charge its AGM battery. Bench charge your battery before installation. Then CHARGE it regularly and frequently.

2012年12月1日 · I had my battery replaced yesterday due to an emergency and not close to any bmw dealer and I put an autozone battery h8 recommended. duralast platinum. now i am getting an electrical malfunction error, transmission error, windows do not go up and down, doors do not lock, wipers keep on wiping, on my 2008 528i.

2022年6月24日 · BUT any replacement battery will ALWAYS need to be REGISTERED (as explained by mattmar1). If the OP replaced his old 92 AH H8/49 AGM battery with an H7 85AH or H9 105AH battery, then yes…the new battery will need to be coded first…then registered. BMW battery registration has been a requirement since the intro of the new gen BMWs.

2023年11月22日 · The 9 yo battery in my '15 435i is always charging at >14v. So much for the often reported BS that BMW only charges on overrun/coasting. It also sits for weeks at a time and starts reliably. If your battery was drained, I am surprised the dealer didn't charge the battery before recommending a replacement.

2016年1月17日 · 1) Register the battery replacement itself by telling the computer a new battery was just put in. 2) Code the new battery capacity if different than the one previously in place. You must know the Ah value of the new battery. If the new battery is the same capacity as the old one..... then only step 1 is required.

2019年4月7日 · But BMW has since discontinued that battery and replaced it with a battery of slightly different specs. The battery they are now using to replace the above listed part number is made by EastPenn. The power ratings on it is 12V - 92Ah - 850CCA.

2019年1月22日 · I have a '13 528i (F10, N20) and was looking at purchasing the Carly adapter for Iphone ($83 on Amazon) and corresponding app (full version on iphone is $60) to register a new battery. My local Autozone carries Duralast Platinum batteries for $195, which appear to be made by Johnson Controls; dealer charges $200 for BMW battery.

2017年8月2日 · My 5/2009 build 2010 E60 was delivered with an FLA battery. I suspect earlier models were similarly built. I just replaced it in 11/2016, getting 7 years, 6 months use. I put in an FLA from Wal-Mart. Of course owners with '06 & '07's are likely on their second battery replacement, so be sure to check the battery type you currently have.

2023年10月31日 · Also, unless BMW makes multiple 105 Ah batteries, the part # that seems correct for the OEM battery is 61-21-5-A40-E33 However most sites claim this will NOT fit my 2013 750i.
