Question 1

How much does it cost to replace a Tata Nexon EV battery in India?

Accepted Answer

Depending on the variant, out-of-warranty replacement typically costs between ₹5,50,000 and ₹7,00,000 for the 30.2 kWh MR pack, and between ₹7,50,000 and ₹9,00,000 for the 40.5 kWh LR (Max) pack, before diagnostics and labour. This is an industry estimate — Tata Motors does not publish an official price list, so readers should confirm current pricing with an authorized dealership.

Question 2

How long does the battery in a Tata Nexon EV last?

Accepted Answer

The 30.2 kWh MR and 40.5 kWh LR variants are backed by an 8-year / 1,60,000 km warranty, while the newer 45 kWh Nexon.ev variant carries Tata's Lifetime* HV Battery Warranty (15 years from registration, unlimited km for fair personal use, first owner only, subject to ownership-transfer notification for any subsequent owner). Thanks to LFP chemistry and liquid cooling, real-world capacity retention beyond the warranty period is typically observed to be strong under normal Indian driving and charging patterns.

Question 3

Can you replace a single dead cell module in a Tata Nexon EV battery?

Accepted Answer

Tata Motors may repair or replace the HV battery pack or individual battery cells depending on diagnostic findings, at the company's sole discretion. The specific repair approach — whether module-level, cell-level, or full pack replacement — is determined by Tata Motors' approved service procedures rather than being a standard, routinely available option. Customers should confirm the applicable repair process for their specific vehicle with an authorized Tata Motors service centre.

Question 4

Is the Tata Nexon EV battery warranty transferable to a second buyer in India?

Accepted Answer

No, not on equal terms. The Lifetime* HV Battery Warranty on the eligible 45 kWh Nexon.ev variant applies to the first registered owner, and per Tata's official terms, requires the second (or subsequent) owner to formally notify Tata Passenger Electric Mobility Limited of the ownership transfer; even where notified, coverage steps down to the standard 8 years / 1,60,000 km, counted from the original registration date rather than resetting.

Question 5

Does the Nexon EV support Battery-as-a-Service (BaaS) like the MG Windsor EV?

Accepted Answer

No. Tata sells the Nexon EV with the battery pack included outright — there is no rental or BaaS subscription alternative, unlike MG's model on the Windsor EV.

Question 6

Can the Tata Nexon EV battery be repaired instead of replaced?

Accepted Answer

Tata Motors may repair or replace the HV battery pack or individual battery cells depending on diagnostic findings, at the company's sole discretion. The specific repair approach is determined by Tata Motors' approved service procedures rather than being a fixed customer choice, and module-level repair should not be assumed to be standard, routinely available practice across all service centres. Customers should confirm the applicable repair process with an authorized Tata Motors service centre. Independent EV battery specialists are separately developing repair capability outside the OEM network, though using them typically voids any remaining Tata warranty. Ultimately, repair feasibility depends on the specific battery's condition and the authorized service centre's diagnostic findings.
