It’s not surprising that the 30 kWh versions suffer more from charge/discharge cycles, since they are more often charged to 100 %. Remember that the option to limit the charge to 80 % was removed when the 2014 model year debuted (to game EPA range ratings). This means that none Nissan Leaf with the 30 kWh battery has this option.
If you want to improve your electric car battery lifespan, you should know that it’s better to charge to 80 % and discharge till 0 % than to charge to 100 % and discharge to 20 %. Nonetheless, if you can use the battery between a SoC (State of Charge) of 80 and 20 % even better… And if you really want to take care of your battery, try to use it only between 70 and 20 %.
Moreover, having the battery sitting at 100 % SoC is worse with the 30 kWh version than it’s in the 24 kWh variants. Because in the same conditions the 30 kWh battery will likely be hotter. In the 24 kWh battery pack, each module has 4 cells, while in the 30 kWh variant there are 8 cells per module. A more dense battery pack will dissipate heat more slowly.
Why are 24 kWh batteries more affected by time?
It’s also not surprising that the 24 kWh versions are more affected by time and older Leafs show much higher degradation levels, since the “lizard” battery only arrived in 2014 with the 2015 Nissan Leaf.
24 kWh battery (model years 2011-2014): higher degradation levels
24 kWh battery (model years 2015-2016): lower degradation levels (lizard battery)
While the “lizard” battery cells remained with LMO cathodes, they had the electrolyte improved to be more heat tolerant. Only in 2016, Nissan finally started using NCM cathodes in their battery cells with the introduction of the 30 kWh battery version.

Accelerated reported battery capacity loss in 30 kWh variants of the Nissan Leaf:
Leafspy
Capacity Ah:
- A new battery is 66 Ah, = 100% (24000 / 66 = 364 V)
- 1 SOH bar lost around 50 Ah,
- 2 SOH bars lost around 46 Ah,
- 3 SOH bars lost around 42 Ah.
Hx (resistance to accepting charge):
Hx correlates almost exactly with the remaining capacity, as a percentage. So a Hx reading of 89 means the car has about 89% of its original capacity left. That reading alone will suffice to evaluate a used Leaf, although Hx plus Ah is better.
Capacity Ah:
A new battery should read around the 67.36 Ah, but don't worry if it's a little less, as for some reason some new cars have been less than this, but after a few thousand miles it increases to this 67.36 area.
GID:GIDS reading is a measurement of exactly how much Watt hour of usable battery energy you have. It has been suggested that 1 GID is equal to 80 Wh. On a full 100% , a new LEAF should have roughly 284 GIDS.
24000 Wh / 80 Wh = 300 GIDs.
