Batteries That Don't Die
Inexpensive and rugged lead-acid batteries, as everyone knows, can start a car in the dead of winter. But their excessive weight and their tradeoff between power and life -- the powerful version in your car doesn't last more than a few years -- have kept them out of hybrid vehicles and prevented their widespread use in all-electric vehicles.
Now the humble lead-acid battery has been gutted and redesigned, cutting its weight, extending its lifetime, and putting it in the same performance category as the nickel-metal hydride batteries used in today's hybrid cars, according to Firefly Energy, a Peoria IL company that's developing the new batteries for specific applications.
These new batteries are about one-third to one-quarter as heavy as traditional lead-acid batteries, and can be made about as powerful as nickel-metal hydride batteries without sacrificing longevity, says Mil Ovan, senior vice president and Firefly cofounder.
