Nevertheless, Toyota sold less than 1400 of the plug-in hybrid RAV4s (they were NOT all-electric) over 6 years, so they ceased the model's run. It still holds that NiMH batteries were not practical for EVs. They had terrible range, memory problems and needed replacement after just 2 years. Anyone who used a cell phone or laptop from the 90s or early 00s understands this: batteries didn't last, that's why they were often engineered so that you could replace the batteries easily. Compared to today's electronics like iPhones and Macbooks that have internal lithium ion batteries embedded on device. This is because they work for years and years and lose very little maximum charge over that tme.
