In pretty much all of the past markets where nickel-based batteries were replaced by lithium-based batteries, the resale value of the nickel-based models takes a sharp nosedive when the lithium models hit the market. Will this same thing happen with hybrid automobiles equipped with the older battery technology? It's hard to say, considering that power tools and laptops are so different than cars, but it may be a cause for concern if some car makers continue pressing on with nickel technology while others jump forward with lithium technology. Read over this article from the Washington Post. The author seems to jump from EPA mileage statistics straight through to resale value... very different topics to be sure. We'd rather have newer and better batteries to be sure, but if the older units continue to function well, what difference does it make?
