Procedures

Battery Charging
1 Before charging a discharged battery inspect and repair the following conditions, if necessary:
- Loose accessory drive belt.
- Pinched or grounded wiring harness to the generator or voltage regulator.
- Loose wiring harness connections at the generator or voltage regulator.
- Loose or corroded connections at battery, headlamp panel junction wire or engine ground.
- Carry out generator charging checks.
- Excessive battery quiescent drain due to:
- engine compartment, load space, glove compartment and courtesy lamps remaining on (switch damaged or out of adjustment, glove compartment left open).

Battery Charging - Maintenance-Free Batteries

WARNING: KEEP BATTERIES OUT OF REACH OF CHILDREN. BATTERIES CONTAIN SULFURIC ACID, AVOID CONTACT WITH SKIN, EYES OR CLOTHING. SHIELD YOUR EYES WHEN WORKING NEAR THE BATTERY TO PROTECT AGAINST POSSIBLE SPLASHING OF THE ACID SOLUTION. IN CASE OF ACID CONTACT WITH SKIN OR EYES, FLUSH IMMEDIATELY WITH WATER FOR A MINIMUM OF 15 MINUTES AND SEEK PROMPT MEDICAL ATTENTION. IF ACID IS SWALLOWED, CALL A PHYSICIAN IMMEDIATELY. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY.

WARNING: BATTERIES NORMALLY PRODUCE EXPLOSIVE GASES WHICH CAN CAUSE PERSONAL INJURY, THEREFORE DO NOT ALLOW FLAMES, SPARKS, OR LIGHTED SUBSTANCES TO COME NEAR THE BATTERY. WHEN CHARGING OR WORKING NEAR A BATTERY ALWAYS SHIELD YOUR FACE AND PROTECT YOUR EYES. ALWAYS PROVIDE ADEQUATE VENTILATION. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN PERSONAL INJURY.
1 Cold batteries will not readily accept a charge. Therefore, batteries should be allowed to warm up approximately to 15 degrees centigrade (59 degrees Fahrenheit) before charging. This may require 12 hours at room temperature depending on the initial temperature and battery size.
2 A battery which has been completely discharged may be slow to accept a charge initially, and in some cases may not accept a charge at the normal charger setting. When batteries are in this condition, charging can be started by use of the 'dead battery' switch which is fitted to certain types of battery chargers. Follow the manufacturer's instructions when carrying out this procedure.
3 To determine whether a battery is accepting a charge, follow the manufacturer's instructions for the charger.
4 After releasing dead battery switch and with the charger still operating, measure battery voltage. If the voltage is 12 volts or higher, the battery may be accepting a charge and may be capable of being recharged. If the temperature of the battery is below 15 degrees centigrade (59 degrees Fahrenheit) the battery may require charging for up to two hours before the charge rate is high enough to show on the charger ammeter. It has been found that all un-damaged batteries can be charged by this procedure. If a battery cannot be charged by this procedure, it should be replaced.
5 A rapid recharge procedure has been developed for recharging batteries that have passed the 'No-Load Test' and only need a recharge. This can be due to non start battery failures or battery discharged in vehicle due to key-off loads.
6 The battery can be rapidly recharged by using either of the following methods:
Perform a two hour charge using a constant current of 20 amps (manual setting on the charger).
Perform a two hour charge using a constant voltage (automatic setting on the charger).

Quiescent Current Measurement
1
NOTE:
The following quiescent current measurement does not apply to vehicles with the Tracker system installed. If the vehicle is installed with the tracker system the quiescent current may be up to 14 milliamps higher. If non-jaguar approved accessories are installed the following measurements may not apply.
Disconnect the battery ground cable. For additional information, refer to Specifications
2 Check the vehicle off-load battery voltage. If below 12.5 volts, install a fully charged slave battery for the tests and recharge the vehicle battery.
3 Connect a 'shorting' link lead between the negative battery terminal and the negative battery lead, before connecting a suitable ammeter to the battery (with the negative test lead clip to the negative battery terminal, and the positive test lead clip to the battery negative lead).
4
NOTE:
Make sure that all electrical accessories are switched off.
Operate the key fob unlock button to disarm the vehicle security system.
- Select ignition mode (without starting the engine) for around 10 seconds.
- Deselect ignition mode, close doors, hood & luggage compartment lid latch.
- Lock vehicle.
- After 15 minutes on vehicles with TPMS installed or 4 minutes on vehicles without TPMS installed, remove shorting link & note ammeter reading.
- The quiescent current should be less than 35mA.
- Replace Shorting link.
- Unlock the vehicle.
- Superlock the vehicle.
- After 15 minutes, on vehicles with TPMS installed, or 4 minutes, on vehicles without TPMS installed, remove shorting link & note ammeter reading.
- The quiescent current should be less than 35mA.
5
NOTE:
In the unlocked state, the vehicle will take 30mins to shut down to its min quiescent current.
If intermittent wake-ups are suspected, monitor battery current continuously
6 Disconnect the ammeter. Reconnect the battery ground cable. For additional information, refer to Specifications
