Who makes batteries for Subaru?
12-volt batteries are typically supplied by GS Yuasa; the high‑voltage packs for electrified Subaru models use Panasonic cells as part of the Toyota‑Subaru alliance. Market-by-market variations apply.
Subaru’s battery question involves two distinct components: the conventional 12‑volt starting battery and the high‑voltage traction battery used in hybrids and all‑electric models. This article explains who makes those batteries, how the supply chain works, and what it means for vehicles like the Solterra and Crosstrek Hybrid.
12-volt batteries: Suppliers and scope
12V battery suppliers by market
Below is a look at the main suppliers and the regions where they are typically used in Subaru vehicles.
- GS Yuasa: A long‑standing supplier of 12‑volt lead‑acid starting batteries for many Subaru models across Japan, Asia, and other markets.
- Denso: In some regions, Denso‑branded 12‑volt units are deployed as an alternative or companion supplier depending on the model and trim.
- Regional variations: Subaru’s global footprint means multiple partners for 12‑volt batteries, with the exact supplier determined by market and production year.
The 12‑volt battery supply chain is regionally tailored, reflecting Subaru’s international manufacturing and aftermarket networks.
High-voltage battery packs: who makes them
Cell suppliers and assembly
The high‑voltage packs for Subaru’s electrified vehicles sit at the center of a joint development with Toyota. Cells and modules are supplied by a primary supplier, with assembly and integration handled through a network of partners.
- Panasonic: The main cell supplier for Subaru’s e‑TNGA platform, providing lithium‑ion cells used in Solterra and other hybrids as part of the Toyota‑Subaru alliance.
- Pack assembly and integration: Panasonic and partner facilities handle module assembly and final pack integration, often in collaboration with Toyota and Subaru plants in regions where Solterra and related models are built.
- Regional variations and future changes: While Panasonic is the primary cell supplier for current e‑TNGA battery packs, supply arrangements can evolve with market needs or new product programs.
The high‑voltage battery program reflects Subaru’s broader electrification strategy and its partnership with Toyota, ensuring a shared platform and supply chain for next‑generation models.
Summary
Subaru’s battery supply chain is split between conventional 12‑volt batteries and high‑voltage packs for electrified models. The 12‑volt units are largely supplied by GS Yuasa, with some regional variation by market. The high‑voltage packs used in Solterra and other hybrids rely on Panasonic cells under the Toyota‑Subaru alliance, with final assembly managed through Panasonic and related joint ventures. As Subaru expands its electrified lineup, supply arrangements may continue to adapt to market conditions and partnerships.
