The Buick Envision model is equipped with three types of batteries, all of which are Johnson Controls-supplied batteries based on German technology. Here are the relevant details: 1. Johnson Controls invested $158 million several years ago to build a factory in Zhejiang, introducing Johnson Controls' battery technology, mainly producing high-capacity, fully sealed, maintenance-free automotive lead-acid batteries and other high-performance power batteries, including VARTA and OPTIMA batteries. 2. With the popularization of start-stop batteries in China, the factory introduced an AGM battery production line last year, and the start-stop batteries produced are also available on the market. 3. The battery products used in the Envision starting from November 2015 are estimated to use VARTA core components and are assembled domestically.
