40kWh Nissan Leaf Battery

Price: TBA

Engineered in New Zealand, the Electric Garage 40kWh battery is a high capacity replacement solution for the Nissan Leaf. It is fully compatible with both first and second generation Leafs, offering a seamless upgrade that restores and often exceeds the vehicle's original range, delivering up to 240 km per charge under typical normal driving conditions.

This battery was developed by some of New Zealand's most experienced vehicle design and automotive electrical engineers. Their expertise ensures a solution that is technically robust, safe, and tailored specifically for New Zealand conditions.

Unlike other aftermarket solutions, this battery requires no additional electronics. It works exclusively with the Nissan Leaf's original BMS and vehicle electronics, meaning all standard functions continue to operate exactly as the factory intended — without modifications, adaptors, or compromises.

The prismatic modules we use are significantly more heat tolerant than the original AESC pouch cells used in the Nissan Leaf, offering improved stability and performance in demanding conditions.

Unlike all other aftermarket options we have tested, our battery retains the full structural integrity of the original Nissan Leaf case. We do not modify the case; all factory mounting points remain intact, ensuring a safe, secure and factory style fit. The result is a drop-in upgrade that's mechanically sound and electrically compatible with the Leaf's existing systems.

The battery system has been designed with electrical safety as a top priority. All high voltage components are securely enclosed, properly insulated, and professionally terminated using industry standard connectors and safety interlocks. The pack includes internal fusing and isolation monitoring to help protect users, technicians, and the vehicle in all operating conditions.

It includes fast charging support, battery management integration, and is backed by a 3 year / 100,000 km warranty.

If you're looking for a reliable, future proof battery solution to keep your Leaf on the road for years to come, this is the pack built to do just that.
