It's one of those bad feelings that we have all experienced: Turn the key and nothing happens. Yep, our Porsche had a dead battery.

It came to life with a jump, but a long weekend on the charger didn't reanimate the dead tissue. Since we didn't know the battery's purchase date--the case wasn't marked--we looked for a replacement.

The books list a gigantic group 49 battery for our car. It checks in at 56.5 pounds. We figured we could find something lighter or better. Today's absorbed glass mat batteries are appealing, and then there's the lightweight units now on the market.

Since wanted to get the car up and running asap, we picked up a lighter group 91 battery from our local NAPA. The Porsche's battery tray can accept this unit, and it weighs 36.5 pounds--yes, lighter options are out there, but generally not on the shelf here in Daytona Beach. We're giving up some cranking amps, but considering we don't see too much freezing temperatures we'll take the gamble for now.

The car is now back among the living, and we're still checking out our other options. At a minimum, we need to get a proper cover on the hot lead.
