We know your heart was in the right place, as gas is so expensive these days! Yes—you can upgrade the battery on a 2012 Nissan
Leaf. The 2012 Nissan EV comes equipped with a 24-kWh lithium-ion battery pack that produces only 73 miles of range. But you can upgrade to a 30-kWh that offers up to 107 miles of range or a 40-kWh that provides up to 170 miles of electric range. Experts would not recommend the 62-kWh on a 2012 Leaf model due to the limits of the onboard charger.
But it’s not the most affordable upgrade. Upgrading your 2012 Nissan Leaf with a 30-kWh battery upgrade could run you between $5,000 and $8,000, while a 40-kWh might end up costing you between $8,000 and $12,500 depending on your location and where you take your 2012 Leaf for a battery upgrade.
While you might have already missed Nissan’s battery pack warranty that’s only good for eight years or 100,000 miles, you might still be able to get a free upgrade for a 40-kWh battery replacement! Nissan recently announced that all Leafs with a 24-kWh or 30-kWh battery would receive this upgrade due to the degrading performance of the original battery.
Just make sure to reach out to your local Nissan dealership to see if you qualify for this fantastic deal!
