Understanding battery type is central to ensuring reliable starts and proper operation of your 2018 Chevrolet Sonic. Different chemistries—standard flooded lead-acid versus AGM—have unique charging profiles and performance characteristics. Our technicians verify the factory-specified chemistry for your vehicle using OEM records tied to your VIN, then recommend the correct replacement chemistry to maintain the charging system’s balance and accessory performance.

Choosing the dealership for this service ensures that the battery type installed meets manufacturer tolerances; this prevents electrical anomalies, reduces repeated service costs, and supports the lifespan of your vehicle’s electrical components. For warranty-protected work, having a certified dealership perform replacements is essential to maintain coverage and to ensure any future warranty claims are supported by proper installation records.
