2025 Tank 500 48V MHEV: Identify the Mild-Hybrid Battery Before Raising a Battery Enquiry

An owner says “the battery has a problem”, but the job card does not identify the power system. Purchasing can go wrong immediately. The Mexican 2025 Tank 500 Luxury powertrain sheet explicitly lists a 48V ternary lithium battery and MHEV identity. Identifying the mild-hybrid system first helps keep batteries with different purposes out of the same enquiry.

48V is voltage, not capacity

The powertrain entry reads 3.0T V6 Dual Injection MHEV. The battery entry specifies ternary lithium, with 48 under the V heading. [T06] Do not rewrite it as 48Ah or infer energy capacity, dimensions or connectors. Retain the original unit in purchasing records and attach a readable photo of the actual battery's identification plate.

Describe the reported battery problem more precisely

Record a particular power-related dashboard message, failure to enter an expected vehicle state and visible battery damage separately. The technical sheet does not associate these symptoms with a mandatory replacement item. Ordinary battery experience and values cannot establish the condition of the mild-hybrid battery.

An initial enquiry may say “48V MHEV-related battery; factory identity pending confirmation [To be verified]”. Keep the mild-hybrid system, ordinary onboard power supply and complete powertrain name distinct. The source provides no interchangeable-battery list; shared labels such as lithium battery or vehicle battery do not justify substitution.

Scope and verification

This article is limited to Mexico; MY25; GWM TANK 500; Luxury 3.0T V6 MHEV. [Model year and trim basis][T01] Factory equipment information identifies functions and parts; it is not a fault or replacement criterion.

No public data were available for mild-hybrid battery Ah and kWh values, OE numbers, testing and replacement parameters, ordinary power-supply construction, or separate supply and interchangeability of the mild-hybrid battery. [To be verified] No public data were available in the reviewed material for OE numbers, repair parameters, separate parts availability or compatibility and interchangeability. [To be verified] Compatibility or interchangeability must be checked using the vehicle identification number (VIN) and the local factory parts catalogue in Mexico.
