1. INTRODUCTION

This document sets out the requirements for care and maintenance of batteries and thereby the standard of battery care at dealers and retailers for new vehicles

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.

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

1. Most 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 24 HOURS before the customer takes delivery.
2. The battery can be discharged by the following mechanisms
3. 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.
4. 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.

1. 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.
2. For keyless vehicles, the Smart Key must be stored at least 5m away from the vehicle when the vehicle is parked or stored.
3. 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.

2.1 DEALER DEMONSTRATION VEHICLES

Vehicles used as dealer demonstrator(s), in a showroom, must be connected to a 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 related work in the workshop, vehicles that are undergoing such activities MUST have a 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 suitable power supply connected.

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

1. It is the dealer / retailers responsibility to make sure the battery is not allowed to go flat by following the instructions and processes defined in this information.
2. However, if circumstances dictate that a new vehicle must be jump started due to a flat battery while 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.
3. The vehicle should also undergo investigation as to why the battery went flat.
4. Do not connect the jump starting cable to the negative (-) terminal of the battery. Always connect to the recommended grounding point. As defined in the owners handbook or service documentation for that vehicle.

2.5 AGM BATTERIES

1. AGM batteries must not be charged above 14.8 Volts. Doing so will damage them.
2. AGM Batteries must be tested with a capable battery tester as detailed in the equipment section (Section «5»(/land-rover/range-rover-sport/l320-2009-2013/remont/charging-system/#battery-charging-system-general-information__5-determining-battery-condition) ) of this procedure.

Note. Under no circumstances should the battery be disconnected with the engine running because under these conditions the alternator 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.
