The RAV4 EV is a plug-in, all-electric variant of the RAV4. Produced from 1997 to 2003 for fleet lease, this "zero emission" model was only offered for public sale for seven months in 2002, in very small quantities in California. Powered by an advanced Nickel-metal hydride (NiMH) battery pack capable of storing 27 kWh, the RAV4 EV can go up to 193 km (120 mi) between charges, and came with a 97,000 km (60,000 mi) battery warranty.[citation needed] A total of 1,484 units were leased and/or sold in California,[7] and as of mid-2012, almost 500 units were still in use.[8]
