Battery and Charging System - General Information - Battery Care
Requirements
Description and Operation
1. INTRODUCTION

This document defines the requirements for care and maintenance of batteries, and the standard of battery care at dealers and
retailers for new vehicles.

This applies to all types of 12 Volt Lead Acid Batteries used in Jaguar and Land Rover vehicles whether they are conventional
flooded technology or Absorbed Glass Mat (AGM – also known as Valve Regulated Lead Acid (VRLA)) technology and also
applies to both Primary, Secondary and Auxiliary Batteries. AGM batteries offer improved resistance to cycling as seen in stop
start applications.

In order to prevent damage to the battery and ensure a satisfactory service life, all processes detailed within this document
must be rigorously adhered to.
It is equally important therefore to note the following key points:

All new vehicles leave the factory with either a transit relay installed and/or have a transit mode programmed into the
vehicle control modules. The transit relay must be removed and the transit mode disabled (where applicable) using an
approved diagnostic system, NOT MORE THAN 72 HOURS before the customer takes delivery.
The battery can be discharged by the following mechanisms:
- Self Discharge: - A lead acid battery will very slowly discharge itself due to its own internal chemical processes
whether it is connected to a vehicle or not.
- Quiescent Discharge: - The vehicle electrical systems when connected to the battery will draw charge from the
battery.

12 Volt Lead Acid Batteries rely on internal chemical processes to create a voltage and deliver current. These processes and
the internal chemical structure of the battery can be damaged if the battery is allowed to discharge over a number of weeks /
months, or is left in a discharged state for a lengthy time period.

On vehicles with conventional ignition keys, these must not be left in the ignition lock barrel when the transit relay
has been removed, otherwise quiescent current will increase and the battery will discharge more rapidly.
For keyless vehicles, the Smart Key must be stored at least 5m (16 ft) away from the vehicle when the vehicle is
parked or stored.
AGM Batteries are fully sealed and cannot have the electrolyte level topped up.


NOTE: Dealers and retailers involved in the storage / handling of vehicles and replacement batteries have a responsibility
to ensure that only a fully charged battery may be processed through the distribution selling chain.
2. GENERAL RULES FOR BATTERY CARE
2.1 Dealer Demonstration Vehicles

Vehicles used as dealer demonstrator(s), in a showroom, must be connected to a JLR approved showroom conditioner capable
of delivering 50 Amps. This will prevent the battery from being damaged.
2.2 Software Reflash, SDD work or Ignition On related workshop activities

Due to the high electrical current demand and high depth of discharge that can occur during vehicle software re-flash activities,
SDD work or ignition on (power mode 6) related work in the workshop, vehicles that are undergoing such activities MUST have a
JLR approved power supply capable of delivering 50 Amps or more.
2.3 Extended Vehicle Rework

For any extended vehicle rework that results in consuming vehicle power, either the battery should be disconnected or a JLR
approved power supply connected.
2.4 Jump Starting New vehicles before they have been delivered to the customer

It is the dealer / retailers responsibility to make sure the battery is not allowed to discharge by following the
instructions and processes defined in this manual.
However, if circumstances dictate that a new vehicle must be jump started due to a discharged battery whilst the
vehicle is in the dealer / retailers care, the battery on this vehicle must be replaced with a new one prior to delivery
to the customer at the dealer / retailers liability.
The vehicle should also undergo investigation as to why the battery became discharged.
Do not connect the jump starting cable to the negative (-) terminal of the battery. Always connect to the recommended
earth point. As defined in the owners handbook or service documentation for that vehicle. 2.5 AGM Batteries

AGM batteries must not be charged above 14.8 Volts. Doing so will damage them.
AGM Batteries must be tested with a capable battery tester as detailed in the Equipment section (Section 5) of this

Any actions must be carried out in accordance with the table shown in the Determining Battery Condition section (Section 6)
of this procedure. The details must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage
document.
For additional information, refer to: New Vehicle Storage Form (100-11 Vehicle Transportation Aids and Vehicle Storage, Description and Operation).
4.3 PDI / DELIVERY TO CUSTOMER

Before the vehicle is handed over to the customer and as part of the PDI, the condition of the battery needs to be confirmed.
The battery condition must be checked in accordance with the battery test process utilizing a JLR approved tester as outlined
in the Equipment section (Section 5) of this procedure.


NOTE: The Midtronics code from the tester must be recorded on the form.

Any actions must be carried out in accordance with the table shown in the Determining Battery Condition section (Section 6)
of this procedure. The details must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage
document.

4.4 REPLACEMENT BATTERIES FOR SERVICE

All service replacement batteries must have the battery condition checked within 24 hours of receipt and controlled on a ‘First
In First Out’ basis to ensure batteries are not allowed to age unnecessarily.

For batteries in storage and not yet fitted to a vehicle, they must be stored in a dry environment, not in direct sunlight or
under any direct heat source. Any batteries exhibiting any forms of damage or corrosion must not be fitted to any vehicle. Any
batteries which are dropped must be scrapped, this applies even if no external damage is apparent.

The battery condition must be checked every 30 days in accordance with the battery test process utilizing a JLR approved
tester as outlined in the Equipment section (Section 5) of this procedure.

Any actions must be carried out in accordance with the table shown in the Determining Battery Condition section (Section 6)
of this procedure.The details must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage
document.
For additional information, refer to: New Vehicle Storage Form (100-11 Vehicle Transportation Aids and Vehicle Storage, Description and Operation).
4.5 BATTERY MAINTENANCE

Any battery whether it is in a vehicle or a replacement part must be tested and/or re-charged every 30 days and MUST be
re-charged after every 90 day period.
4.6 BATTERY TEST PROCESS

It is recommended that this test is conducted at least 24 hours after the vehicle engine has been run or the battery charged to
avoid the need of surface charge removal. If time constraints make this unacceptable then the surface charge must be
removed.
Surface Charge Removal

A vehicle which has had its battery charged or been driven in a 24 hour period before the test, must have its surface charge
removed.

Turn on the ignition (power mode 6) but do not start the vehicle
Switch on the headlamps on high beam for a minimum 3 minutes
Switch off the headlamps
Wait a minimum of 5 minutes before recording test results for any battery measurements
Battery Test

The battery may be tested either on a bench or on the vehicle.

The battery condition must be checked in accordance with the battery test process utilizing a JLR approved tester as outlined
in the Equipment section (Section 5) of this procedure.


NOTE: The Midtronics code from the tester must be recorded on the form.

Any actions must be carried out in accordance with the table shown in the Determining Battery Condition section (Section 6)
of this procedure. The details must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage
document.
For additional information, refer to: New Vehicle Storage Form (100-11 Vehicle Transportation Aids and Vehicle Storage, Description and Operation).


CAUTION: DO NOT connect the tester to any other circuit or chassis point other than the battery negative terminal.

5. EQUIPMENT

CELL BATTERY Verify surface charge removed. Disconnect battery from vehicle and re-test. If result repeats after
surface charge removal, replace battery. DO NOT RECHARGE. UNABLE TO DO TEST Disconnect battery from vehicle and re-test. 7 BATTERY CHARGING

It is essential that a suitably ventilated defined area exists in each dealership / retailer for battery charging.


CAUTION: It is very important that when charging batteries using the traction charger or other stand-alone chargers that
the charger is set for the correct type of battery before charging commences. If the wrong switch is selected the result would
be a battery that is not charged fully and / or overheating can occur. Follow the manufacturers operating instructions.

Batteries MUST BE tested and if necessary charged every 30 days and charged after 90 days irrespective of any test. It is
recommended that dealers / retailers always have fully charged batteries ready for use.


CAUTION: Do not charge AGM batteries with voltages over 14.8 Volts as this will damage the battery.

A designated controlled area must be allocated for scrap batteries and clearly controlled as such.
To bring a discharged but serviceable battery back to a fully charged condition proceed as follows:
Check and if necessary top-up the battery electrolyte level. (Flooded maintainable batteries only)
Charge the battery using a JLR approved charger as detailed in the approved equipment document following the
manufacturers operating instructions.


NOTE: When using the Midtronics Diagnostic Charger, automatic mode must always be used. After charging and analysis,
the charger may display ‘Top-Off Charging’, Hit STOP To End. Do not stop charging until the current falls to 5A or less,
otherwise the battery will not be fully charged.
Following charging, a post charge battery condition test must be carried out in accordance with the table shown in the
Determining Battery Condition section (Section 6) of this procedure.


NOTE: The Midtronics code from the tester must be recorded on the form.

Any actions must be carried out in accordance with the table shown in the Determining Battery Condition section (Section 6)
of this procedure. The details must be recorded on the New Vehicle Storage Form which is part of the new vehicle storage
document.
For additional information, refer to: New Vehicle Storage Form (100-11 Vehicle Transportation Aids and Vehicle Storage, Description and Operation).
8 BATTERY REPLACEMENT

If it is determined that a battery requires replacement, always refer to the appropriate section of the workshop manual for
instructions on removing and installing the battery from the vehicle.

On in service vehicles fitted with a Battery Monitoring System (BMS), the BMS control module must be reset following the
installation of a new battery. The BMS control module reset procedure must be performed using an approved diagnostic

the secondary battery (if fitted) and passes through a grommet in the floorpan.

On new vehicles the primary battery positive terminal is fitted with a transit relay. The transit relay must removed using the
correct process detailed in the Pre Delivery Inspection (PDI) manual.

The battery negative terminal is fitted with a BMS control module. The control module is integral with the battery negative
cable and communicates with the GWM via a LIN bus connection. The battery condition information is passed to the GWM
which controls the generator output accordingly.


CAUTION: To avoid damage to the BMS control module, always use the body ground point in the engine compartment and
not the battery negative terminal when connecting a slave power supply.

Failure to use the recommended ground point will lead to the setting of a DTC. Incorrect information of battery condition will
be retained by the BMS control module due to the unmonitored current flow into the battery. The system will however,
recognize and compensate for the change in battery status after a period of time.

If a new battery is fitted, the BMS control module will require re-calibration using a Jaguar approved diagnostic system.
Replacement of the BMS control module requires no action as the control module will re-calibrate automatically.

SECONDARY BATTERY - DUAL BATTERY VEHICLES ONLY

The secondary battery is located in a tray on the next of the primary battery and is secured to the DBJB with a bracket. The
battery negative (-) terminal is connected via a cable to the vehicle body. The positive (+) terminal is connected by a cable to
the DBJB. The battery is vented via a tube which is connected with a T piece to the vent from the primary battery and passes
through a grommet in the floorpan.
The state of charge of the secondary battery is monitored by the Gateway Module (GWM).

BATTERY MONITORING SYSTEM (BMS)



The BMS (battery monitoring system) control module is located on the primary battery negative (-) terminal. The module is
located on the battery post and is clamped to the post with a bolt and nut.

The primary battery negative ground cable is connected to the BMS control module and is attached to a ground stud on the
vehicle body.

The BMS control module is connected into the vehicle wiring harness via a multiplug. The BMS control module receives a 12V
power supply direct from the primary battery positive terminal. A LIN (local interconnect network) bus connection provides
communication between the BMS control module and the ECM for control and monitoring of the primary battery current drain and state of charge.
The BMS control module measures battery current and voltage, which it communicates to ECM.

CAUTION: Due to the self-calibration routine, it is recommended that all power supply diagnostic testing is carried out
using the Jaguar approved diagnostic system rather than a digital multimeter.

The BMS control module is able to generate DTC (diagnostic trouble code)'s to help diagnose primary battery or generator
power supply issues. These DTC's can be read using the Jaguar approved diagnostic system. The Jaguar approved diagnostic
system can also be used to implement a primary battery and generator self test routine. For additional information, refer to
the Diagnosis and Testing section of the workshop manual.
If a fault is detected, the GWM (gateway module) will override the BMS control module.

The BMS control module DTC's can be used to help diagnose battery or generator power supply faults. The DTC's are stored in
GWM. The Jaguar approved diagnostic system has a process for an automated power supply diagnostic procedure. The
procedure provides a menu driven process to locate a fault in a logical sequence. The procedure uses the capability of the BMS
control module and generator LIN bus controlled functions to provide current flow information and will detect if the BMS control
module or generator are functioning correctly.

NOTE: Flooded batteries does not have AGM on the label

The following steps must be carried out to ensure correct operation of the EXP-1080 during the battery test procedure
