- jblow 14y agoTesla's EV batteries already in common use last a lot longer than that (7-10 years), so I am not sure what your point is.
- Osmium 14y agoThere's a lot of clever engineering that can be done when your battery doesn't need to be small enough to fit inside a phone or a laptop.
- dandrews 14y agoMy Segway LiFeMgPO4 (mfg by Valence) batteries are five years old with 7700 miles. They provide about 90% of the range they did when new. Your "year or 2" is well taken, but suggests cheaper (e.g. some Chinese knock-offs) cells or systems that aren't very smart about preserving battery efficacy. Long life is possible with appropriate care.
