Land Rover Discovery: General Rules for Battery Care

  1. GENERAL RULES FOR BATTERY CARE

2.1 RETAILER SHOWROOM/DEMONSTRATION VEHICLES

Vehicles used as retailer 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.

Vehicles used as retailer demonstrator(s), in a showroom, must be taken out of transit mode or have the transit relay removed. For additional information on the transit relay installation, refer to the Transit Relay Installation Summary table.

Vehicles used as retailer demonstrator(s), in a showroom, must have the starter motor, horn and wiper fuses removed as a minimum.

For additional information, refer to: Showroom Preparation (101-02 Showroom Preparation, Description and Operation).

WARNING:

Showroom conditioners are only required to be turned on during showroom opening hours, outside these hours switch off all showroom conditioners.

NOTE:

For retailers who do not have floor sockets installed in the showroom a slave battery process has been outlined below. The slave battery process is only a TEMPORARY process until floor sockets are installed into the showroom. The retailer is responsible for making sure the process is set up and is also responsible for the procurement of slave batteries and other supporting equipment. The retailer is also responsible for developing a conformance plan to install floor sockets.

2.1.1 RECOMMENDED SLAVE BATTERY RESPONSIBILITIES/PROCESS

Showroom Representative Responsibilities

  1. All vehicles in the retailer showroom that are being used for display purposes MUST be fitted with a slave battery if the JLR approved battery conditioner cannot be installed.
  2. All vehicles fitted with a slave battery must be logged and tracked by a nominated showroom representative who has been trained in the Battery Care Requirements process. For additional information, Refer to the following Excellence training courses Battery Care Requirements EDASS00025_0814 and Good Battery Care EDAS400059_1114
  3. A list of the vehicle VIN details must be provided to the department where the original vehicle battery will be stored and maintained
  4. Make sure the installation of the slave battery is coordinated with the workshop department and installed in a timely manner
  5. Check on a daily basis for a low battery warning display on the vehicle information display. If required, contact the workshop department to charge the slave battery.
  6. Make sure that the slave battery condition is checked on a weekly basis using the Midtronics EXP-1080. If required, contact the workshop department to charge the slave battery
  7. When the display vehicle has been sold, notify the workshop department to install the original battery (in a fully charged state) within 72 hours of vehicle handover to the customer
  8. When the display vehicle is being returned to the vehicle storage compound, notify the workshop department to install the original battery (in a fully charged state), refit the transit relay (if required) and put the vehicle into transportation mode
  9. Record all battery inspections and battery charging dates and supporting information on the showroom and slave battery report form.

For additional information, refer to: Showroom and Slave Battery Condition Report Form (414-00 Battery and Charging System - General Information, Description and Operation).

WORKSHOP REPRESENTATIVE RESPONSIBILITIES

  1. Removal of the original vehicle battery from the vehicle
  2. Installation of the slave battery to the display vehicle
  3. Clearly label and identify a slave battery
  4. Attach the slave battery identification tag JLR-415-010 (Available from the Jaguar Landrover equipment website) onto the vehicle keys identifying that the vehicle is fitted with a slave battery
  5. Check, maintain and record the original battery condition information in accordance with the JLR storage procedure and policy.

    For additional information, refer to: Showroom and Slave Battery Condition Report Form (414-00 Battery and Charging System - General Information, Description and Operation).

  6. Make sure the slave battery has the same part number as the original battery fitted to the display vehicle.
  7. Make sure the TOPIx procedure is followed for the removal and replacement of the original vehicle battery
  8. Install the original vehicle battery within 72 hours of vehicle handover to the customer
  9. Make sure if the display vehicle is being returned to the vehicle storage compound the original battery is installed (in a fully charged state), refit the transit relay (if required) and put the vehicle into transportation mode
  10. Remove the slave battery identification tag JLR-415-010 from the vehicle keys once the original battery has been refitted
  11. The original battery should be stored separately and clearly identified with the VIN from the vehicle from which it was removed.

TRANSIT RELAY INSTALLATION SUMMARY

TRANSIT RELAY INSTALLATION SUMMARY

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. Approved showroom conditioners can be found on the JLR tooling website.

CAUTION:

Do Not carry out any Software downloads with either or both the transit mode on or the transit relay fitted, this could damage vehicle modules.

2.3 EXTENDED VEHICLE REWORK

For any extended vehicle rework that results in consuming vehicle battery power a JLR approved power supply should be connected, refer to : Battery Support Unit connection procedure (414-00 battery and charging system - General information, General procedures).

2.4 JUMP STARTING NEW VEHICLES BEFORE THEY HAVE BEEN DELIVERED TO THE CUSTOMER

  • It is the 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 retailers care, the battery on this vehicle must be replaced with a new one prior to delivery to the customer at the 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 procedure.

NOTE:

Under no circumstances should the battery be disconnected with the engine running because under these conditions the generator can give a very high output voltage. This high transient voltage will damage the electronic components in the vehicle. Loose or incomplete battery connections may also cause high transient voltage.

  1. HEALTH AND SAFETY PRECAUIONS

WARNINGS:

BATTERY CELLS CONTAIN SULPHURIC ACID AND EXPLOSIVE MIXTURES OF HYDROGEN AND OXYGEN GASES. IT IS THEREFORE ESSENTIAL THAT THE FOLLOWING SAFETY PRECAUTIONS ARE OBSERVED.

Batteries emit highly explosive hydrogen at all times, particularly during charging. To prevent any potential form of ignition occurring when working in the vicinity of a battery:

  • Do not smoke when working near batteries.
  • Avoid sparks, short circuits or other sources of ignition in the battery vicinity.
  • Switch off current before making or breaking electrical connections.
  • Ensure battery charging area is well ventilated.
  • Ensure the charger is switched off when: a) connecting to a battery; b) disconnecting from the battery.
  • Always disconnect the ground cable from the battery terminal first and reconnect it last.

Batteries contain poisonous and highly corrosive acid. To prevent personal injury, or damage to clothing or the vehicle, the following working practices should be followed when topping up, checking electrolyte specific gravity, removal, refitting or carrying batteries:

  • Always wear suitable protective clothing (an apron or similar), safety glasses, a face mask and suitable gloves.
  • If acid is spilled or splashed onto clothing or the body, it must be neutralized immediately and then rinsed with clean water. A solution of baking soda or household ammonia and water may be used as a neutralizer.
  • In the event of contact with the skin, drench the affected area with water. In the case of contact with the eyes, bathe the affected area with cool clean water for approximately 15 minutes and seek urgent medical attention.
  • If battery acid is spilled or splashed on any surface of a vehicle, it should be neutralized and rinsed with clean water.
  • Heat is generated when acid is mixed with water. If it becomes necessary to prepare electrolyte of a desired specific gravity, SLOWLY pour the concentrated acid into water (not water into acid), adding small amounts of acid while stirring. Allow the electrolyte to cool if noticeable heat develops. With the exception of lead or lead-lined containers, always use nonmetallic receptacles or funnels. Do not store acid in excessively warm locations or in direct sunlight.

Due to their hazardous contents, the disposal of batteries is strictly controlled. When a battery is scrapped, ensure it is disposed of safely, complying with local environmental regulations. If in doubt, contact your local authority for advice on disposal facilities.
