2025 Mercedes-Benz GLA-Class Battery Type

Choosing the correct battery type for your 2025 Mercedes-Benz GLA-Class is essential to preserving vehicle functionality and longevity. Modern Mercedes-Benz vehicles frequently use advanced 12-volt battery chemistries — such as absorbent glass mat (AGM) designs — to support start-stop systems, regenerative charging, and a high density of electronic modules. AGM batteries provide improved charge acceptance, longer cycle life, and better vibration resistance versus conventional flooded cells. At Mercedes-Benz of Sudbury, we specify and install batteries that match factory chemistry and performance specifications so your vehicle’s energy-management systems behave predictably. Our technicians will confirm the precise type required for your VIN and options, advise on the differences between available chemistries, and explain why OEM-equivalent batteries often yield lower total cost of ownership through improved reliability. We also perform charging system diagnostics to ensure the new battery charges correctly; failing to check the alternator or wiring can mask issues that will shorten battery life. For customers who value reliability and factory-level performance, dealership service ensures the right battery type is installed and fully supported by warranty and technical documentation.
