What kind of battery is in a 2017 Chevy Spark?
In the 2017 Chevrolet Spark lineup, most models use a conventional 12-volt automotive battery for starting and electrical systems. The all-electric variant, known as the Spark EV, uses a separate high-voltage lithium‑ion battery pack to power the motor. This article details both configurations, how they differ, and what owners should know about maintenance and replacement.
Gasoline Spark: Conventional 12-Volt Battery
Here are the essential facts about the 12-volt battery that handles starting and electronics in the gasoline-powered Spark.
- Type: 12-volt lead-acid automotive battery that is usually sealed and maintenance-free.
- Function: Provides power to the starter, ignition system, lights, radio, ECU and other accessories; it does not drive the vehicle's propulsion or run the main traction motor.
- Capacity: Typical storage around 40–60 amp-hours (Ah) with cold-cranking amps (CCA) commonly in the 300–500 range, though exact specs vary by market and supplier.
- Location and replacement: Mounted under the hood in the engine bay; replacement is a routine service task that most DIYers can perform with basic tools.
- Lifecycle: In normal climates, replacement is often needed every 3–5 years depending on use, climate, and maintenance; look for slow starting or dim cabin lights as warning signs.
In summary, the gasoline Spark uses a standard 12‑volt lead‑acid battery, the same class of battery found in many compact cars.
Spark EV: High-Voltage Lithium-Ion Battery
For markets where Chevrolet offered the Spark EV, propulsion comes from a high‑voltage lithium‑ion battery pack, separate from the 12‑volt system.
- Type: High‑voltage lithium‑ion battery pack used to power the electric motor; the 12‑volt system still exists to run accessories and control electronics.
- Energy capacity: Typically usable energy on the order of 19–21 kilowatt-hours (kWh) from a total pack around 21–23 kWh nominal, depending on the battery variant and condition.
- Purpose and design: Powers the vehicle’s electric motor for propulsion; designed and managed by a battery management system (BMS) to protect cells and optimize charging/discharging.
- Location: Pack is mounted under the floor of the vehicle, beneath the passenger area, with cooling and safety systems integrated.
- Charging: Supports Level 1 (standard household) and Level 2 (220–240V) charging; some markets offered DC fast charging options for faster replenishment.
In short, the Spark EV uses a separate high‑voltage lithium‑ion battery pack for driving, distinct from the conventional 12‑volt battery in the gasoline model.
How to tell which Spark you have
Identifying whether you own the gas Spark or the Spark EV is straightforward: look for a plug‑in charging port and EV badges for the electric version, or notice the presence of a conventional engine with an exhaust system for the gasoline model. Your vehicle’s VIN or owner's manual will also confirm the exact configuration and battery specs.
Maintenance and safety notes
Handle the 12‑volt battery with care and follow standard safety practices when inspecting terminals or replacing it. The high‑voltage traction battery in the Spark EV is a high‑voltage system and should only be serviced by qualified technicians using proper procedures and PPE.
Summary
The 2017 Chevy Spark comes in two battery configurations: the gasoline version uses a standard 12‑volt lead‑acid battery for starting and electronics, while the Spark EV uses a high‑voltage lithium‑ion pack for propulsion. Always verify your model to follow the correct maintenance and replacement steps.
