What Is the Battery Price of the Tata Nexon EV?
The battery price of the Tata Nexon EV in 2025 is ₹5.5 lakh to ₹6.5 lakh, based on the model and source of replacement. Prices are slightly higher at authorized Tata Motors service centres, but they guarantee original lithium-ion battery packs with complete software integration and warranty protection.
Third-party suppliers may offer lower prices, but their batteries often lack proper certification and system compatibility. Such units can lead to poor performance or void warranty coverage.
I’ve compared both options, and the genuine replacement from an authorized centre offers far better reliability and long-term value. Paying more upfront ensures consistent performance, verified safety, and manufacturer-backed support.
What Is the Battery Capacity of the Tata Nexon EV?
The battery capacity of the Tata Nexon EV depends on its variant. The Nexon EV Prime uses a 30.2 kWh lithium-ion pack, while the Nexon EV Max features a 40.5 kWh battery.
Both are built with nickel-manganese-cobalt (NMC) chemistry, which provides stable thermal control and longer charge cycles.
The higher-capacity 40.5 kWh pack naturally costs more, as it contains more cells and greater energy storage. However, it delivers improved efficiency and durability, which offsets the higher replacement price over time.
In my ownership experience, Tata’s battery design balances cost with endurance, making it one of the most dependable EV systems in its class.
How Much Does It Cost to Replace a Tata Nexon EV Battery?
The battery replacement cost of the Tata Nexon EV in 2025 is ₹5.5 lakh to ₹6.5 lakh, depending on the model and service location. This price includes the cost of the new lithium-ion battery pack, software recalibration, and professional installation at authorized Tata workshops.
I replaced my EV battery through a certified Tata service centre, and the process was transparent and efficient.
The technicians conducted a full diagnostic check, verified cell performance, and paired the new pack with the vehicle’s Battery Management System (BMS) to ensure accurate charge readings and power output.
Third-party replacements can cost less, but they often compromise on quality and compatibility. Non-OEM batteries may not integrate with Tata’s BMS, leading to reduced efficiency or loss of warranty.
Spending slightly more on a genuine replacement secures reliability, safety, and long-term performance.
What Is the Warranty Period for the Tata Nexon EV Battery?
The battery warranty of the Tata Nexon EV is 8 years or 1,60,000 km, whichever comes first. This warranty covers manufacturing defects, capacity degradation, and performance issues that occur within normal usage conditions.
Tata guarantees that the battery will retain at least 70% of its original capacity throughout the warranty period. That means even after several years of driving, the pack should still deliver dependable power and efficiency.
To keep the warranty valid, follow Tata’s charging and maintenance guidelines. Avoid deep discharges and overuse of fast chargers when possible.
Based on my own experience, regular software updates and timely service checks help preserve both battery health and warranty protection.
Final Thoughts
After driving and maintaining the Tata Nexon EV, I’ve realized that understanding its battery system isn’t just about numbers — it’s about long-term peace of mind.
The battery defines how dependable your EV feels after years of use. Paying attention to its health, service history, and warranty coverage helps avoid expensive surprises later.
Choosing authorized replacements may seem costly upfront, but it preserves performance, warranty protection, and system safety all of which directly affect resale value and daily reliability.
If you plan to keep your Nexon EV for the long haul, treat the battery like an investment, not an expense. Proper charging habits and timely maintenance will keep it running efficiently for many years.
