Battery sections are ordered from the GM Battery Service Center (U.S.) or through York Electronics (Canada). Prior to ordering, be sure to have all necessary information related to the vehicle, including any set DTCs, the Capacity Code (from the GDS2 HPCM2 data/voltage data screen), and the battery pack identification number. Refer to Bulletin #18-NA-236 for complete details before ordering battery sections.
Battery Section Requirements
Some models have specific requirements that must be followed before placing an order for that model.
2017-2019 Bolt EV Requirements – Bolt EV sections for U.S. models will be custom balanced by the GM Battery Service Center. However, a short, final balancing must be performed once installed into the battery pack.
Bolt EV models built before VIN 1G1FW6S09H4180682 must be serviced as an entire pack and are not eligible for section replacement for quality purposes.
2011-2012 Volt Requirements – Volt section orders require a chemistry determination procedure to be completed. Some cells from the 2011-2012 model years are incompatible with each other. Follow the chemistry determination procedure in Service Information doc. I.D. 4877428. Contact the GM Battery Service Center for battery section availability.
Malibu Hybrid, Eco, and eAssist Requirements – For the 2016-2019 Malibu Hybrid, individual sections are not yet available for service. For an individual cell concern, the battery pack must be replaced. Refer to Bulletin #18-NA-084 for additional information on battery concerns.
Battery Section Returns
TIP: The battery must be returned in the original exchange shipping container. Never ship a damaged or compromised battery without prior approval.
The GM Battery Service Center will provide a return bill of lading with a return shipping for U.S. dealerships. Batteries are not to be returned to the Warranty Parts Center (WPC). Follow the return instructions included with your particular shipment. If you receive a special parts return request from the WPC for part review by engineering, the WPC Bill of Lading will supersede the paper BOL originally included in the shipment and provide the proper address. A copy of the repair order must be included in the battery return.
In Canada, refer to the latest GM Parts Bulletin for information on returning EV batteries and sections, which can be found under Parts Bulletins & Resources in the application section of the Parts Department page on GM GlobalConnect.
