2 Answers
The battery model for the BMW F18 is 20-92/H8-92-L-T2-A, and the battery brand for the BMW 5 Series is VARTA. F18 launch date: The F18 was first launched on June 12, 2009. F18 refers to the chassis number, which can also be understood as the sixth generation of BMW. The dimensions of the sixth generation BMW are: 4899/1860/1464mm, with a wheelbase of 2968mm. Another major change in the sixth generation is the first-time use of a double-wishbone independent front suspension. From the first generation of the 5 Series, the front suspension used was a MacPherson strut independent suspension. F18 models: The sixth generation BMW models include the 520i, 523i, 528i, 535i, 535i xDrive, 550i, and 550i xDrive.
As a mechanic who frequently repairs BMWs, I can tell you that the BMW F18 typically uses a 90Ah AGM battery, usually in H8 size, such as the Bosch S6 AGM or Exide EA680. AGM batteries are specifically designed to support start-stop systems, offering better discharge depth than conventional lead-acid batteries and greater durability during frequent starts. When replacing it, note that the battery is located in the trunk—just open the rear cover to access it. More importantly, BMW has an intelligent charging system, so when installing a new battery, you must use an OBD diagnostic tool to reset the computer via programming. Otherwise, the system may misjudge the battery level, leading to abnormal charging or functional issues. I recommend choosing certified brand batteries to avoid premature failure, which could compromise driving safety. Regularly checking battery life and voltage is also a key maintenance point. Testing cold-cranking performance before winter can help prevent the hassle of stalling on the road.
