The 2011 BMW 135i uses a 12-volt lead-acid battery located in the trunk, typically a Group 48 (also known as H6) battery with about 90 amp-hours of capacity and a cold-cranking amperage around 680–760 A, depending on the exact specification and market.
Battery location and general notes
The battery is mounted in the rear cargo area, under a floor panel or trim cover. This arrangement supports BMW’s packaging and weight distribution goals. In most configurations, the 135i does not rely on an optional Start-Stop system, and the battery is generally a standard flooded 12V type rather than an advanced AGM battery.
