2012 Chevrolet Tahoe Hybrid Battery Type

The 2012 Chevrolet Tahoe Hybrid relies on a hybrid traction battery pack coupled with a conventional 12V auxiliary battery. The traction pack is purpose-built for hybrid operation and is distinct from the 12V battery used for electronics and accessories. While many vehicles from this era utilized nickel-metal hydride chemistry for the high-voltage pack, exact construction and configuration can vary by build and equipment. Coggin Chevrolet at the Avenues verifies the correct OEM chemistry and replacement options by VIN and inspection so you receive a compatible, reliable pack. Our certified technicians install OEM or certified remanufactured options according to factory specifications, perform required system checks, and update vehicle software as needed. Choosing the dealership ensures that the replacement battery type matches factory requirements, preserving performance, emissions compliance, and warranty eligibility. We also explain the trade-offs between new OEM packs, remanufactured units, and any available warranties so you can make a confident, cost-effective decision.

2012 Chevrolet Tahoe Hybrid Battery Size

Battery size for hybrid vehicles is not just a single number like conventional battery group sizes. The high-voltage traction pack is defined by pack architecture, voltage, and cell configuration, while the 12V battery uses a conventional group size that is important for fit and cold-cranking performance. For the 2012 Chevrolet Tahoe Hybrid, Coggin Chevrolet at the Avenues confirms the exact pack and 12V group by VIN and vehicle inspection, then supplies the correct OEM replacement. Accurate sizing is crucial: the wrong 12V group can affect mounting and electrical performance, and any mismatch on the traction pack can impair charging, efficiency, and safety. Our service process includes verifying fitment, testing under real load conditions, and completing system calibrations to ensure the replacement functions as intended. Relying on the dealership minimizes the risk of incorrect parts, repeated labor, and potential long-term costs—delivering immediate savings and preserving vehicle reliability and resale value.
