A 2020 Subaru’s gasoline models use a standard 12-volt lead-acid battery, while hybrids add a separate high-voltage propulsion battery. The exact battery type and size can vary by model and trim, so check the owner’s manual or the battery label when replacing.
Battery technology in the 2020 Subaru lineup
Subaru’s 2020 lineup centers on a reliable 12-volt electrical system for most models, with some variations to accommodate additional electronics or hybrid powertrains. The following overview covers what owners should know about the batteries in these vehicles.
- 12-volt battery: Gasoline-powered 2020 Subarus use a standard 12-volt lead-acid battery to power starting, lighting, and accessories.
- AGM option on certain trims: Some higher-trim levels or vehicles with substantial electrical load may use an absorbed glass mat (AGM) battery for improved durability and performance.
- Model- and trim-specific specs: The exact battery size, group size, and cold-cranking amps vary by model and trim; refer to the battery label or owner's manual for specifics.
- Location and service: In most models, the battery is located under the hood; replacement or testing should be performed by a qualified technician.
- Hybrid and electric components: The Crosstrek Hybrid and other potential hybrid variants use a separate high-voltage propulsion battery in addition to the 12-volt system; servicing those packs follows dealer guidelines and safety protocols.
In short, gasoline-model Subarus from 2020 typically require a 12-volt battery, with some trims possibly using AGM. Hybrids carry a high-voltage battery for propulsion alongside the standard 12-volt system.
Hybrid and electric models
Among the 2020 Subarus, the Crosstrek Hybrid (and any other hybrids) employs a high-voltage battery for the electric-drive portion, while the 12-volt battery continues to handle ordinary electrical needs. The high-voltage system is not user-serviceable in the same way as the 12-volt battery and requires dealer involvement for maintenance or replacement.
- The high-voltage (hybrid) battery powers propulsion and is managed as part of the hybrid system.
- Maintenance and diagnostics for the hybrid battery are typically conducted by Subaru service centers using specialized equipment.
- If you notice hybrid-system warning lights or suspect decreased performance, have the system inspected at an authorized dealer.
For any 2020 Subaru, always verify the exact battery type and size for your specific model and trim by consulting the owner’s manual or the battery label when purchasing or replacing.
Summary
Most 2020 Subarus rely on a standard 12-volt lead-acid battery, with some trims potentially using an AGM variant to support extra electrical demand. Hybrids such as the Crosstrek Hybrid use a separate high-voltage battery for propulsion in addition to the 12-volt system, and those packs require dealer-assisted service. Always check your model’s documentation to confirm the exact battery specifications.
