Fortunately, Nissan offers a battery pack warranty that is good for eight years or 100,000 miles, whichever comes first. In this scenario, the manufacturer will cover any costs associated with battery replacement.

However, if you’ve already hit the mileage mark or bought your 2017 Nissan Leaf without a warranty, you will be on the hook for paying these expenses out of pocket. Wondering if it’s worth it? Read on—we will cover battery replacement costs, whether or not you can upgrade your battery, strategies to increase battery lifespan, and more.

How much does it cost to replace a 2017 Nissan Leaf battery?

The total cost to replace a 2017 Nissan Leaf battery will range from $4,500 to $5,500.

The 30-kWh lithium-ion battery pack alone will cost you between $3,500 and $4,500, while labor costs for the replacement average around $1,000. So, is the replacement worth the investment?

The answer is obvious if your battery pack warranty (eight years or 100,000 miles) is still active. In this case, Nissan will fully cover replacement costs if your battery’s performance capacity falls below 75% or fails completely.

However, if you’re warranty has lapsed (or you never had one in the first place), you will have to evaluate whether or not battery replacement is the financially correct decision. According to Kelley Blue Book, a 2017 Nissan Leaf is worth $13,000 to $16,000. Since the battery replacement costs are still well below the vehicle's value, it is certainly a viable option for your Nissan Leaf if it is otherwise in good condition.

Can you put a new battery in an old Nissan Leaf?

Yes, you can put a newer battery in your 2017 Leaf. In fact, if you still have an active warranty, you may qualify for a free upgrade if your current battery’s performance is lacking.

Nissan

recently announced that Leaf models with 24- or 30-kWh batteries with degrading performance, as indicated by the conditions of the warranty, would receive an upgraded 40-kWh battery replacement. Pretty sweet deal, right? It almost makes you hope that your old battery drops the ball.

And the insane value of the battery warranty becomes even more apparent when you research the out-of-pocket costs to upgrade your battery. Without a warranty, a 40-kWh battery pack will cost you between $6,500 and $7,500. And that’s not to mention the increased labor costs associated with the tricky modifications that are necessary to accommodate a larger battery.

Nissan Leaf battery capacity and range

The 2017 Nissan Leaf was the final model of the first generation, marking the transition away from the 30-kWh battery pack—for the better, of course.

And while we’re reminiscing, we might as well reflect on the Leaf’s progress as a prominent competitor in the electric vehicle space. Here’s a complete timeline of the Leaf’s battery pack growth and the accompanying

driving range

improvements:

Model years	Battery capacity	Driving range
2011 – 2013	24 kWh	73 to 75 miles

How long does a 2017 Nissan Leaf battery last?

The lifespan of a 2017 Nissan Leaf 30-kWh battery pack is 100,000 to 150,000 miles. Since the battery warranty extends to 100,000 miles, there’s a good chance that you’ll be covered for most replacements that aren’t a result of estimated wear and tear.

But if you don’t have a warranty, it’s essential that you do everything you can to extend the lifespan of your battery—or else you could be paying for expensive battery replacement costs sooner than expected.

So, here are some longevity strategies we recommend implementing as a 2017 Nissan Leaf owner:

Avoid high temperatures. Exposure to intense and consistent external heat can cause your battery to degrade faster. Try to keep your Leaf cool during storage and use.

Skip the fast charger. DC fast charging stations can get your Leaf’s battery from zero to 80% in just 30 minutes. However, this rapid charging method isn’t easy on your battery. It’s best to stick to a Level 2 or Level 1 household adapter when possible.

Don’t aim for a 100% charge. It may seem counterintuitive, but storing a 100% charge puts a lot of strain on your battery. Charging to 80% instead of 100% can extend the life of your battery.
