Over in the US, Nissan is set to enhance the warranty of the battery modules in its Leaf EV to stem the concern from certain owners about the battery’s durability. It seems that battery life wasn’t previously spelled out in the vehicle’s overall warranty.
The limited warranty coverage in the US, which applies to all existing Leafs as well as those entering the market in 2013, will see Nissan offering to repair or replace the lithium-ion battery if it loses more than 30% of its ability to hold a charge (in this case, below nine bars of the available 12 bars displayed on the battery capacity gauge) for the first five years or 90,000 km.
Automotive News reports that the move comes after months of communication between Nissan and seven US Leaf owners in Phoenix, Arizona, who claim that their vehicle’s battery is aging faster than Nissan told them to expect.
In 2010, the automaker stated that the Leaf’s batteries would behave much like handphone batteries, slowly losing its ability to hold a full recharge after years of driving. The company told Leaf buyers that they could expect a 20% loss in charging capacity after five years of use, based on normal driving patterns.
The Phoenix owners, however, claimed the capacity loss was happening much faster than that. Nissan dispatched engineers to investigate, and found that the seven owners had been putting twice as much mileage on their cars as a normal driver would.
Nissan says that the new battery warranty coverage is to reassure consumers, adding that save for vehicles in areas of extreme summer heat and subject to heavier-than-normal driving, a typical Leaf owner isn’t expected to see that kind of capacity loss. In line with developments, the company is planning to unveil an improved battery gauge that will display remaining capacity with better precision.

Not bad :)
Too bad. What after 90k km and how frequent you can change? I do not think the battery is cheap.
90k km is way too low from 5 years, perhaps you will have to replace the battery every 3 years. I better buy conventional car with petrol pump.
Sam Loo, come defend RV of Nissan.
How much will cost us to charge this battery full every time. How far it can go for full single charge?
I think tan chong or whoever into this EV/ Hybrid vehicle should think long term, and bring this whole battery thing and make it local. That would jump start the industry faster.
I wonder what will be done to those battery once it’s depleted.
I think the cost for the battery will RM10K above. last time when i visit UMW Kuching they said the battery cost about RM13K above. That make me think twice.
