Battery Load Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Mercury Marauder, 2004 Mercury Grand Marquis, 2004 Ford Crown Victoria, 2003 Mercury Marauder, and 2003 Mercury Grand Marquis. However, it is still accessible from the selected car via links, so may be relevant.

Connect battery tester according to tool manufacturer's instructions. Load test battery at approximately one-half cold-cranking amperage rating for 15 seconds while observing battery voltage. If voltage reading is 9.6 volts or more, battery is okay. If voltage reading is less than 9.6 volts, charge battery and retest. If loaded battery voltage is still less than 9.6 volts after charging battery, replace battery.
