[s-cars] Do I want an Optima?

[Steve Powers]

Optimas are very good batteries. If you want a great battery, go with
Odyssey batteries. They're also sealed and are outstanding for
vehichles not regularly driven (near zero leakage).

The other nice thing about them is the power density. A smaller and
lighter Odyssey battery will deliver the same power as a standard (or
Optima) battery.
