Battery And Charging System - General Information (G2323766): Specifications

STARTUP BATTERY SPECIFICATION

Item Specifications
Type Absorbed glass mat (AGM)
Capacity 90 Ah 
Cold cranking amps 850 CCA 
Reserve capacity 150 minutes

Startup battery disconnect/connect 

CAUTION:
  • The vehicle status and start up battery condition must be established before attempting battery disconnect/connect. Reference must then be made to the following table to establish the relevant procedure to be followed.
  • After connecting the start up battery, the steering wheel must be turned to full left-hand and full right-hand lock with the engine running. This allows the dynamic stability control system to calibrate the steering wheel position. Failure to follow this instruction may result in a variety of Instrument Panel Cluster (IPC) warning lamps being illuminated.
NOTE:
  • If there is insufficient capacity in the startup battery to disarm the alarm, the alarm may sound on connection of the startup battery - turning the ignition key to position II will disarm the alarm.
  • If a new startup battery is installed, the startup Battery Monitoring System (BMS) must be reset using Jaguar Land Rover approved diagnostic equipment.

Vehicle Jump (Emergency) Starting - Using Another Vehicle 

WARNING:
  • Take care when working near rotating parts of the engine.
  • Prior to attempting to start the disabled vehicle, make sure that the parking brake is applied or suitably chock the wheels. Make sure that 'P' - PARK - Automatic Transmission or  NEUTRAL - Manual Transmission is selected.
  • Suitable eye protection must be worn when working in the vicinity of the battery.
  • DO NOT  attempt to start the disabled vehicle if it is suspected that the electrolyte in the battery is frozen.
  • During normal use, batteries emit explosive hydrogen gas sufficient to cause severe explosions and capable of causing serious injury - keep sparks and open flames away from the engine compartment.
CAUTION:
  • Make sure that there is no physical contact between the donor and disabled vehicles other than the booster cables.
  • Make sure that the slave battery/starting aid is of the 12 volt type.
  • Make sure that all electrical systems and ignition are switched OFF prior to connecting the booster cables.
  • Disconnect the booster cables prior to operating any electrical systems.
