According to, the battery pack of the Nissan Leaf is already starting to lose some of its capacity, around 8.3% of the total, or one of the 12 bars showing the state of charge, after only a year in operation. This was to be expected though, as this loss of capacity is an inevitable trait of current batteries, and one of the hurdles faced by EVs in general, along with the recycling scheme for future depleted battery packs.
All the affected cars were from Arizona, and experienced ‘the loss’ after the Leaf had been driven for between 21,812 km (13,633 miles) and 27,200 km (17,000 miles). The owners filed complaints with Nissan, and the manufacturer’s official response was “We’re aware of a few isolated cases where a very small number of consumers are reporting a one bar loss. (We’re talking less than 5 units versus the 12,000 on the road in the U.S.).”

Despite the fact that ‘the loss’ is to be expected, it cannot really be predicted as it is not a linear process, and according to Nissan, batteries encounter higher loss early on in their operational lives, with the curve flattening afterward in a more linear fashion. “Our internal results indicate that the battery will have 80 precent of its capacity under normal use after 5 years, and 70 percent after 10 years,” according to Nissan officials.
