The energy density of lithium-ion batteries per dollar has been doubling every four years for the past 20 years and that trend is continuing which means that by the time you have to replace your battery (assuming 10 years), you can do so at one fifth the original cost (or you can get a battery with 5 times the energy). Sounds like a good deal to me. |
