Tata Nexon.ev & Curvv.ev Now Come With Lifetime Battery Warranty — Is This the Boldest EV Move Yet?

Let’s be honest—battery health is one of the biggest things that make people second guess an electric car purchase. You spend over ₹15-20 lakh on a shiny EV, and then that nagging question comes in: What happens if the battery gives up after a few years?

Well, Tata Nexon Curvv EV just dropped a bombshell in the Indian EV space.

They’ve announced a lifetime high voltage (HV) battery warranty for select variants of the Nexon.ev and Curvv.ev electric SUVs. And guess what? It’s not just for new buyers. Even existing owners of these models will get this upgrade. That’s rare. That’s bold. That’s pretty reassuring, to be honest.

So, Which EVs Are Covered Under This Lifetime Warranty?

Tata didn’t go all out across every variant, so here’s the lowdown:

So yeah, if you’ve got the Nexon.ev 30 kWh, no luck. But for the rest of the higher-capacity versions, Tata’s got your back for a lifetime.

Why This Matters More Than You Think

Let’s be real—battery replacement is expensive. We’re talking ₹5-₹6 lakh or more depending on the car.

Now imagine you’re buying an EV and the company says: “Hey, don’t worry about that cost. Like, ever.”

That’s what Tata’s doing here. This move does three things instantly:

1. Boosts confidence in their EV tech
2. Makes EVs feel less risky to own long-term
3. Helps with better resale value

The warranty also indirectly addresses that annoying “EV batteries don’t last” myth.

What’s the Price of These EVs Anyway?

Here’s a snapshot to help you understand where these models sit in the market:

The Harrier.ev was actually the first Tata EV to get a lifetime HV battery warranty when it launched. But now, Tata’s expanded it to the mid-range EVs, and that’s a bigger market with a lot more people interested.

Bonus for Existing Customers: ₹50,000 Loyalty Discount

If you already own a Tata EV, like maybe the Tiago.ev or Punch.ev, you’re in for a sweet little bonus.

Tata’s now offering a flat ₹50,000 loyalty benefit if you decide to upgrade and buy the Nexon.ev 45 kWh or either of the Curvv.ev variants.

That’s not a small discount. Plus, it’s a nice way to tell existing users, “Hey, thanks for sticking with us.”

So… Why Now?

Electric car competition is heating up fast.

In Q1 FY26 alone, Tata EVs sold 13,495 units, making them the top electric car maker in India. But close on their heels is JSW MG Motor India with 11,199 EV units sold. Brands like MG, Hyundai, and even Mahindra are trying to take that lead spot.

Tata’s latest warranty move feels like a power play. It’s like them saying: “Look, not only do we sell more EVs, we trust our batteries more than anyone else in the game.”

Let’s Break Down the Myths vs Truths

Because EVs still have a bunch of wrong ideas floating around…

Final Take

Let’s be real—EV adoption in India is picking up, but hesitation around battery cost still holds people back.

Tata’s move here is more than just a warranty. It’s a strong vote of confidence in their battery tech. And it’s exactly the kind of move that builds trust, especially in a price-sensitive market like ours.

If you’ve been sitting on the fence about buying an EV, this could be that push you needed.

Because lifetime battery coverage?

That’s peace of mind you don’t find often.
