Battery Care Requirements (G1450751)

Loading...

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

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.
