Mercedes-Benz EQB 350 4MATIC Battery Replacement Cost in India

Quick Answer: The Mercedes-Benz EQB 350 4MATIC uses a 66.5 kWh high-voltage lithium-ion battery. Mercedes-Benz India does not publicly publish an official retail price for a complete battery-pack replacement. Based on available US OEM parts pricing plus an allowance for India-specific logistics, import-related costs, installation, diagnostics and commissioning, a reasonable working estimate for the Mercedes EQB battery replacement cost in India is around ₹18–25 lakh installed, with ₹20–25 lakh as a conservative planning range. This is an indicative estimate, not an official Mercedes-Benz India quotation.

This is a complete high-voltage battery-pack replacement estimate, not the cost of diagnosing or repairing every type of battery fault. A battery warning or fault does not automatically mean the entire pack needs replacing — diagnostics determine whether the appropriate fix is a component repair, module-level work, or a full pack replacement.

How Much Does a Complete EQB Battery Replacement Cost?

Mercedes-Benz India has not published a retail price for a complete EQB 350 4MATIC battery-pack replacement. In the absence of an official Indian figure, the most defensible starting point is Mercedes-Benz’s own US OEM parts documentation, which identifies the EQB 350’s high-voltage unit as an exchange lithium-ion battery, listed at an MSRP of approximately US$16,640, with a selling price near US$15,972.

This is a US OEM parts-catalogue benchmark — not an Indian retail price, and not a Mercedes-Benz India quotation.

Simply converting US$16,640 into rupees and presenting that figure as “the Indian battery price” would misrepresent what an Indian owner actually pays, because the US catalogue price does not include the costs of getting that battery installed and running in an Indian vehicle.

Why the Indian Replacement Cost Is Higher Than the US Parts Price

Arriving at an installed India estimate means adding several cost layers to the US parts benchmark:

None of these India-specific cost layers are individually published by Mercedes-Benz India, so the ₹18–25 lakh estimate below reflects an allowance for them rather than a precise, sourced calculation. No specific customs-duty percentage is assumed or claimed in this figure.

What the ₹18–25 Lakh Estimate Includes

Combining the US OEM parts benchmark with an allowance for India-specific logistics, import-related costs, installation, diagnostics and commissioning gives a reasonable working estimate of ₹18–25 lakh installed for a complete EQB 350 4MATIC battery-pack replacement in India, with ₹20–25 lakh as a conservative planning range.

This is an indicative estimate, not an official Mercedes-Benz India quotation. The actual price can vary by vehicle, VIN, dealer, location, specific battery part number, parts availability, and applicable taxes or charges. The final amount must be confirmed through a VIN-specific quotation from an authorized Mercedes-Benz service centre in India.

Battery Warranty and Replacement Coverage

The EQB 350 4MATIC’s high-voltage battery carries an 8-year / 1,60,000 km warranty. Specific capacity-retention thresholds and the exact conditions under which Mercedes-Benz will repair or replace the battery should be confirmed from the warranty documentation applicable to the specific Indian vehicle.

EQB Battery Recall: What Owners Need to Know

In the United States, Mercedes-Benz has issued a safety recall affecting certain 2022–2024 EQB 250+, EQB 300 4MATIC, and EQB 350 4MATIC vehicles built between December 2021 and May 2024, concerning a potential internal fault in the high-voltage battery that could lead to an internal short circuit and, in rare cases, a fire while the vehicle is parked or being driven.

NHTSA’s 2026 action, campaign 26V073, follows earlier campaigns 25V050 and 25V894, whose software-based remedies were subsequently found insufficient. Under 26V073, Mercedes-Benz has committed to replacing the high-voltage battery in affected US vehicles at no cost to the owner. Interim safety instructions for owners of affected US vehicles include parking outdoors away from structures and limiting charging to 80% until the remedy is completed.

This recall applies to a US recall population of approximately 11,895 vehicles built within the stated production window. These figures describe the US recall population only and should not be read as evidence of the same number, or proportion, of Indian-market EQBs being affected.

This recall is US-specific, VIN-specific, and production-specific — it is not automatically applicable to every EQB sold in India. A recall-related replacement is fundamentally different from an owner-paid out-of-warranty replacement: where a recall applies, the remedy is typically performed free of charge. Indian EQB owners should check their VIN directly with Mercedes-Benz India or an authorized dealer to determine whether any applicable Indian campaign exists for their specific vehicle — the US recall does not automatically extend to India.

Can the Battery Be Repaired Instead of Replaced?

A battery fault does not automatically require replacing the entire pack. Diagnostic findings determine whether the appropriate solution is a component repair, module-level repair or replacement, or a complete pack replacement — the outcome depends on the nature of the fault, the battery’s condition, parts availability, and Mercedes-Benz’s approved repair procedure for that specific vehicle.

A fault confined to a battery module, BMS component, contactor, or another high-voltage component may not necessarily require replacement of the entire battery pack. The appropriate repair depends on diagnostic findings, battery condition, parts availability, and Mercedes-Benz’s approved repair procedure.

Battery Replacement Cost: What Used EQB Buyers Should Know

For anyone considering a used Mercedes-Benz EQB 350 4MATIC in India, the battery represents the largest single cost risk in the vehicle. Before purchase, it’s worth taking these steps:

1. Check the VIN against Mercedes-Benz India’s records for any applicable recall campaign.
2. Obtain a battery diagnostic/health assessment through an authorized Mercedes-Benz service centre.
3. Confirm remaining battery warranty coverage on the specific vehicle.
4. Verify warranty transfer conditions directly with an authorized dealer.
5. Understand that ₹18–25 lakh represents a potential complete-pack replacement scenario, not a guaranteed repair bill — many battery faults may be resolved through component or module-level repair at a lower cost.

Final Verdict

The Mercedes-Benz EQB 350 4MATIC uses a 66.5 kWh high-voltage battery, and Mercedes-Benz India does not publicly publish an official price for a complete battery-pack replacement. A reasonable working estimate — derived from the US OEM parts benchmark plus an allowance for India-specific logistics, import-related costs, installation, diagnostics and commissioning — is ₹18–25 lakh installed, with ₹20–25 lakh as the conservative planning range. This is not an official Mercedes-Benz India quotation, and the actual cost requires a VIN-specific authorized Mercedes-Benz quotation. Not every battery fault requires a complete pack replacement, and where warranty or recall coverage applies, an owner’s actual out-of-pocket expense can be materially reduced — or eliminated entirely.
