Battery and Cables

Vehicles are equipped with a 12-volt maintenance-free battery.

The battery and cable system consists of the following components

1. Battery
2. Battery cable assembly
3. Battery tray

Ford Motor Company strongly recommends that lead-acid batteries be returned to an authorized recycling facility for disposal.

Battery Eye Operation

The purpose of the battery eye is to indicate the state of charge of the battery in the assembly plant and while on the dealership lot. The battery eye can also indicate the state-of-charge when the vehicle is delivered to the dealership and during the pre-delivery inspection process. The battery eye is made up of a viewing plate, 2 balls and a small passage. The balls indicate the specific gravity of the electrolyte by floating higher or lower in the passageway. It is important to note that the battery eye checks the specific gravity on only a single battery cell.

The color of the battery eye indicates the approximate state of charge.

1. Red usually indicates the battery state-of-charge is at 40% or less.
2. Yellow indicates the battery state-of-charge is between 40% and 57%.
3. Green indicates the battery state-of-charge is above 57%.
4. No color/black can occur after the battery has been in service for several years and some of the plate material has coated the balls.
5. A clear battery eye can occur if the battery case becomes damaged and the electrolyte has fallen below the plates.

Note. The battery eye may remain red for a period of time (up to several days), even after the battery is fully charged, because the acid is not yet fully mixed.

Do not install a new battery based solely on the indication of the battery eye. The battery eye color simply indicates the battery state-of-charge, not its condition. For example, a red or yellow battery eye usually indicates the battery is discharged, not defective. If the battery eye indicates the battery may be discharged, it is necessary to recharge the battery before testing its condition.

Charging a Battery

Batteries discharge while the vehicle is on the dealer lot or parked by the customer for an extended period of time due to normal parasitic key-off loads. Also, vehicles still in dealer inventory or in long-term storage may be driven short distances with heavy electrical loads. Over a period of time (30 days or more), this could result in vehicles having shallow or deeply discharged batteries.

1. Deeply discharged - A battery that is drained over a prolonged period of time, such as an unsold vehicle or a vehicle in storage, to the point the battery is dead.
2. Shallow discharge - A battery that is drained by leaving an accessory on for several hours or a few days and has a very low charge.

The vehicle's charging system is designed to supply the electrical power needed to maintain the battery near full charge during normal vehicle use. The charging system is not capable of bringing a deeply discharged battery back near full charge in a short amount of time such as allowing the vehicle to idle for 15 minutes to "recharge the battery." Discharged batteries should be charged using an external charger.

Note. Battery chargers have improved greatly with the addition of the new generation pulse chargers. These chargers pulse current into the battery, breaking down the sulfation layer on the battery plates and generally reduce charging times to less than an hour.

Note. Cold batteries will not readily accept a charge. Therefore, batteries should be allowed to warm to approximately 5°C (41°F) before charging. This may require 4 to 8 hours at room temperature.

The following chart summarizes 2 recommended methods of charging.

Inspection and Verification

1. Verify the customer concern.
2. Visually inspect for obvious signs of mechanical or electrical damage. VISUAL INSPECTION CHART Mechanical Electrical Battery Battery mounting Battery cables Battery posts
3. If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
4. If the fault is not visually evident, go to «Pinpoint Test A»(/ford/taurus-x/i-2007-2009/remont/body-electrical/#battery-mounting-and-cables__pinpoint-test-a-battery-condition-test) .

Normal Operation

Battery condition is determined by measuring battery terminal voltage after a specific discharge current is applied for a specified time period.

This pinpoint test is intended to diagnose the following

1. Battery charge
2. Battery

PINPOINT TEST A: BATTERY CONDITION TEST

1. A1 TEST THE BATTERY CONDITION NOTE: A red test-eye indicates the battery is discharged, not necessarily defective. NOTE: Failure to fully charge the battery before retesting may cause false readings. Verify the battery condition using the battery analyzer. Is the battery OK? YES : If the meter reads GOOD BATTERY, RETURN the battery to service. If the meter reads GOOD-RECHARGE, CHARGE the battery and RETURN it to service. If the meter reads CHARGE & RETEST, fully CHARGE and RETEST the battery. NO : If the meter reads REPLACE BATTERY, INSTALL a new battery. If the meter reads BAD CELL-REPLACE, INSTALL a new battery.

Battery Disconnect

Note. When the battery (or PCM) is disconnected and connected, some abnormal drive symptoms may occur while the vehicle relearns its adaptive strategy. The charging system setpoint may also vary. The vehicle may need to be driven to relearn its strategy.

Note. When the battery is disconnected and connected, the illumination display needs to be calibrated. After the battery is connected, rotate the dimmer switch from the lowest dim position to the full bright, dome ON position.

1. Disconnect the negative battery cable. To connect, tighten to 6 Nm (53 lb-in).
2. Disconnect the positive battery cable. To connect, tighten to 6 Nm (53 lb-in).
3. To install, reverse the removal procedure.
