1.   Depending on how they are used, they can run longer on a charge than comparable-size nickel metal hydride batteries.

2.   Further energy is saved by regenerating energy from braking to recharge the nickel-metal hydride battery.

3.   The automaker may offer nickel-metal hydride batteries beginning next year.

4.   The change is to swap nickel metal hydride batteries, or NiMHs, for the old-fashioned lead-acid kind.

5.   The car used nickel metal hydride batteries, a type that is already common in laptop computers.

6.   The nickel hydride battery is made of environmentally safe materials and holds a charge longer than conventional lead acid batteries.

7.   The output of lithium ion batteries is not necessarily four times that of nickel metal hydride batteries, and it is not measured in volts.

8.   This makes them more susceptible to short-circuiting if exposed to moisture than nickel metal hydride batteries.

9.   Two years ago, he launched RCI, a successful firm that customizes cars and makes environmentally friendly metal hydride batteries.

10.   When the car brakes or decelerates, the gasoline engine is shut off and the momentum of the revolving wheels helps recharge the nickel-metal hydride battery.
