What type of battery do i need for a 2002 ford focus
BCI group size ( 59 ) Originally equipped with Motorcraft BXT-59 battery ( 2008 Ford Taurus )
Defective alternator, dead cell in battery, or something is on pulling power from the battery.
I was looking at the 2002 Ford Taurus Owner Guide and it shows that Vulcan , Flex Fuel , and Duratec - V6 engines came with the ( Motorcraft BXT-36R ) battery
