Nissan Leaf 62 kWh Battery Pack: CATL Replacement Modules and What to Check Before Ordering

A Nissan Leaf 62 kWh battery pack is a 350 V nominal NMC pack built from 24 modules in a 96-series, 3-parallel configuration, rated at approximately 169–180 Ah and delivering 215–226 miles of EPA-estimated range. It was fitted to the Leaf e+ from 2019 and is the most requested replacement pack in the aftermarket because it turns a 150-mile car into a 220-mile car.

Factory-direct 62 kWh packs cost $7,500–$10,500 in 2026, against $12,000–$16,000 for a dealer pack. The gap is not a quality gap; it is the difference between buying from a distributor and buying from the line that welds the modules.

Ritano manufactures 62 kWh packs and 4S1P modules in Dongguan using CATL NMC cells. This guide explains the module arithmetic, the grades that matter, and the checks that separate a pack that lasts eight years from one that fails in eighteen months.

How is a 62 kWh Leaf pack built?

The pack uses 24 modules, each a 4S1P block of four cells in series with a nominal voltage of 14.8 V. The modules are connected in series to reach 96 series cells, which produces the 350 V nominal pack voltage.

The capacity arithmetic is simple and worth memorising, because it explains every "62 kWh, 64 kWh, 69 kWh" listing you will see:

Pack kWh = 14.8 V × module Ah × 24 modules ÷ 1,000

This is why a supplier advertising "62 kWh" may be shipping a 177 Ah build, a 180 Ah build rounded up. Ask for the module capacity in Ah, the module count, and the test protocol. Those three numbers define the pack; the marketing label does not.

What are the 64 kWh and 69 kWh builds?

They are the same 24-module architecture with higher-capacity cells. A 180 Ah module produces 63.9 kWh, which most suppliers list as 64 kWh; a 195 Ah module produces 69.3 kWh, listed as 69 or 70 kWh. Neither requires a different housing, BMS platform, or connector set, which is why they are popular as upgrade options.

The trade-off is cost and heat. Higher-capacity cells cost more per module, and the same air-cooled housing has to dissipate more energy during fast charging. For a vehicle that will be DC-charged frequently in a hot climate, the 177 Ah build is often the more durable choice even though it carries a smaller number on the label.

For builds above 70 kWh, the module count stays at 24 and the cell capacity rises. An 82 kWh pack requires cells in the 225–230 Ah class and is a project-specific build, not a catalogue item. We quote those individually after confirming the vehicle's charging and thermal limits.

62 kWh versus 40 kWh: what actually changed?

The voltage is identical, which is what makes the upgrade technically possible. The housing is not: the e+ pack is taller and heavier, the mounting points differ, and the underbody cover is different. A 62 kWh pack in a 40 kWh car is a conversion that requires hardware and software work, not a lift-and-swap.

Weight matters for a second reason. At roughly 450 kg, a 62 kWh pack changes how the vehicle is lifted, how the pack is crated, and how much freight you pay. Budget for a pallet-rated forklift and a crate rated for the load, not a standard export box.

Will a 62 kWh pack fit your Leaf? 

The 40-to-62 conversion is the one that pays. The vehicle already has the ZE1 electrical architecture, the charger is compatible, and the CAN bridge work is well understood. For an AZE0, the fabrication and labour often consume the range benefit; most workshops are better served by a 40 kWh pack in those cars.

One more constraint belongs in the quote: insurance and vehicle registration. In several markets, changing the pack capacity changes the declared specification. Tell the end customer before the work starts, not after.

Which module grade should you order?

For most B2B buyers, 177 Ah is the volume grade. It produces a 62.9 kWh pack, matches the original e+ range closely, and sits at the best point on the price-per-kWh curve.

177 Ah is the standard replacement grade and the easiest to resell.

180 Ah produces a 63.9 kWh pack and is popular where listings advertise "64 kWh".

195 Ah produces 69.3 kWh for customers who want maximum range and will pay for it.

All grades use the same 4S1P module footprint, so a pack built for 177 Ah can be rebuilt later with a different grade without changing the housing. That interchangeability is useful for distributors carrying stock across several price points.

What should you check before ordering?

Six checks separate a good 62 kWh pack from an expensive lesson.

Module capacity in Ah, with a test report. Not "62 kWh" on a label. A per-module discharge curve at a stated C-rate.

Internal resistance spread. A tight spread across 24 modules predicts stable behaviour under load. A wide spread predicts early imbalance.

Cell voltage delta at rest. Measured after a rest period, not immediately off the charger.

Welding and busbar quality. Laser welds should be uniform, with no discoloration or spatter. Re-welded or bolted busbars are a sign of rework/repair.

BMS and CAN bridge compatibility. Confirm the bridge is configured for the vehicle generation, not just supplied in the box.

UN38.3 and MSDS for the exact configuration. A test summary for a single module does not cover a 450 kg assembled pack.

Ritano tests every pack through cell sorting, laser welding, BMS assembly, insulation, housing, aging, labelling, and final inspection. The capacity and resistance data ship with the unit, and the serial number on the report matches the serial number on the pack.

62 kWh pricing and lead times

Indicative 2026 factory-direct pricing, excluding freight, duties, and installation:

Smaller orders may draw from finished stock; larger quantities are subject to production scheduling.

The spread inside each band comes from cell grade, BMS specification, kit level (bare pack versus pack plus bridge and harness), and packaging. A quotation that does not state those four items is not comparable with one that does.

Shipping a 450 kg Class 9 pack

A 62 kWh pack ships as UN3480 Class 9 dangerous goods. The requirements are the same as for a 40 kWh pack, but the weight changes the logistics:

UN-certified packaging with the pack braced so it cannot shift inside the crate.

UN38.3 test summary and MSDS matching the shipped configuration.

State of charge at or below 30% for air shipments.

Dangerous goods declaration and Class 9 labels on all four sides.

A crate rated for 450 kg plus stacking load, with forklift access.

Sea transit from South China is about 18–25 days to the US West Coast and 30–38 days to Northern Europe. Because of the weight and the dangerous goods class, air freight is usually reserved for a single evaluation pack and priced accordingly.

How should you store a 62 kWh pack before installation?

Store it at 30–50% state of charge, in a dry space between 10 °C and 25 °C, on a pallet that keeps the housing off the floor. Do not stack anything on top of the pack, and do not leave it connected to a charger for weeks. A pack stored at 100% for three months in a warm workshop loses more capacity than one stored at 40% for a year.

Check the terminal voltage once a month. A drop of more than 1 V per month across the pack indicates a module drawing current when it should not, and the pack should be tested before installation rather than after.

Warranty and OEM support

Warranty terms for 62 kWh packs run up to 10 years for qualifying B2B accounts, with the SOH floor, cycle allowance, and claim procedure written into the quotation. Distributors can order OEM labelling, custom packaging, and mixed containers combining 62 kWh packs with 40 kWh units and loose modules.(Warranty terms for 62 kWh packs may be up to 10 years for approved B2B accounts, subject to separate warranty agreement, SOH limits, cycle limits and proper operating conditions.)

Frequently asked questions

Is a 62 kWh Leaf battery worth it?

For a 40 kWh ZE1 owner covering more than 100 miles a day, yes. The upgrade adds roughly 65–75 miles of real-world range, and the pack is the same voltage and architecture. For a low-mileage city car, a 40 kWh replacement is the better economic decision.

Can you upgrade a 40 kWh Leaf to 62 kWh?

Yes, with e+ mounting hardware, an underbody cover, and a CAN bridge. The electrical architecture is compatible because both packs are 350 V nominal. The work is a conversion: budget for parts, labour, and a scan-tool configuration session.

What is the real range of a 62 kWh Leaf?

Expect 200–220 miles in mild weather, 300-310 miles in winter, and 280-300 miles in city traffic. Sustained driving above 70 mph reduces range faster than the EPA cycle predicts.

Does the 62 kWh pack charge faster?

The e+ pack supports DC charging up to 100 kW where the charger and vehicle firmware allow it. The pack itself is air-cooled, so repeated fast charging in hot weather will accelerate degradation regardless of the charger's rating.

What is the minimum order quantity?

One pack for evaluation, with no minimum for a first order. Distributor pricing starts at five packs, and container pricing at twenty. Mixed containers with 40 kWh packs and modules are available.

Do you supply the modules without the housing?

Yes. 4S1P modules in 147, 150, 177, 180, and 195 Ah grades are available for repairers, conversion shops, and stationary storage builders. Modules ship in smaller quantities and are priced per kWh.
