Why Does MG Comet EV Battery Replacement Cost So Much?

A battery replacement bill isn’t just the cost of cells. It typically bundles together:

• Battery cells/modules — the core lithium-ion prismatic cells
• Battery enclosure — the IP67-rated sealed housing
• BMS/electronics — the battery management system
• HV components — high-voltage wiring, connectors, and contactors
• Labour/diagnostics — fault diagnosis, fitment, and calibration
• GST — taxes added on top of parts and labour

MG hasn’t published a component-wise breakdown, so treat the figures above as an all-in estimate, not itemised pricing.

MG Comet EV 17.3 kWh vs 17.4 kWh Battery

Per the official brochure, the 17.3 kWh pack is fitted to the standard Executive, Excite, and Exclusive variants, while the 17.4 kWh pack is listed for the FC (Fast Charging) variants — Excite FC and Exclusive FC — which also support 7.4kW AC fast charging (all other variants charge only via the standard 3.3kW connection). The capacity difference (0.1 kWh) is negligible and doesn’t translate into a separate confirmed replacement price for either version; no official source publishes distinct pricing for the two pack sizes.

MG Comet EV Battery Warranty

Per the MG Comet EV brochure, the high-voltage battery warranty is:

• 8 years or 1,20,000 km, whichever comes first, for the first registered owner under private registration.
• On change of ownership, the HV battery warranty remains 8 years or 1,20,000 km, whichever is earlier, counted from the first-ever date of delivery of the vehicle.
• The 12V battery and tyres are covered separately for 1 year; the infotainment system is covered for 3 years.
• This sits within MG’s broader e-Shield package: 3 years/1,00,000 km vehicle warranty, 3 years roadside assistance, and 2 free labour services on the first scheduled visits.

MG also offers 80+ combinations of extended warranty and RSA plans starting at ₹5,000, for owners who want extra cover beyond the standard terms. Refer to your Owner’s Manual or your MG dealer for the exact terms applicable to your vehicle.

MG Comet EV Battery Replacement vs Battery Repair

Not every battery issue means the whole pack needs replacing. A proper diagnosis at an authorised MG service centre is the necessary first step. Depending on the fault and MG’s prescribed repair procedure, some components may be repairable rather than requiring a full pack swap — though this isn’t guaranteed for every issue or dealer. A complete pack replacement may still be required for certain major faults, severe degradation or physical/water damage, depending on MG’s prescribed repair procedure. Always get a written diagnostic report before authorising any work.

MG Comet EV BaaS Battery Cost

Under MG’s Battery-as-a-Service (BaaS) programme, the battery is provided through a rental arrangement rather than being purchased upfront. The supplied MG brochure lists battery rental at ₹3.2/km, subject to the applicable terms and finance-partner conditions, alongside a lower upfront price (from ₹4.99 lakh for the Executive variant) and a “3-60 Assured Buyback” option. The exact responsibilities for battery damage, replacement and other costs depend on the applicable BaaS and finance-partner terms — check the current offer and conditions with your MG dealer or finance partner before opting in.

How Much Should an MG Comet EV Owner Budget?

• Out-of-warranty planning estimate: ₹3.5 lakh–₹4.2 lakh for a full battery replacement (not an official MG price)
• Actual quotation can vary based on the specific fault, parts needed, labour, and taxes at your service centre
• Check warranty eligibility first — if your vehicle is within the applicable warranty period and conditions, a battery-related issue may be covered
• Get it in writing — ask your MG authorised service centre for a written diagnostic report and replacement quotation before approving any work
