More lithium stock discounts on hybrid cars are already being seen. The reasons I see for this are 1) federal tax credits are lapsing, 2) production costs are coming down, 3) there's more competition, 4) sales goals are still high, and getting higher, and 5) inventory is up.
In case you are using new nickel-metal hydride (NiMH) battery, remember you should not charge the battery for too long or it will overcharge it and end up shortening the life of the battery.

So don't expect the same torque found in a 18 volt nicad cordless drver from a new 12 volt li-ion cordless driver.
The NiMH battery is much friendlier to the environment than the NiCd battery. It showed up in the market after the NiCd. The two types of batteries share the same physical packaging so that you can use a NiMH replacement battery for you NiCd cordless tool. NiMH battery can hold more charges and last longer than the NiCd battery so it costs more. But if you can find a NiMH replacement battery, it is a better deal despite the higher price.
