AGM Battery Care Point

If the vehicle is equipped with an absorbed glass mat (AGM) battery, ensure the replacement battery is a AGM battery of the same specification (cold cranking amperage (CCA), battery standard (EN/SAE)/amp hour rating (Ah)) as the original battery, unless formally instructed by Jaguar/Land Rover

20	BATTERY SUPPORT
	The Battery Support function is used whenever the vehicle comes in to the workshop for regular maintenance or module downloads Re-flashing an ECU can take up to several hours and during that period a lot of current can be drawn from the battery. To support the battery during this process, use the Battery Support function When working on a vehicle, it is recommended that the GR8-1180 JLR diagnostic battery charger is connected and switched to the BATTERY SUPPORT function to ensure that, when the work is completed, the battery's state of charge is maintained at a healthy level Make sure the GR8-1180 JLR diagnostic battery charger is connected (as in steps 1 and 2 from the MAIN Menu above), highlight the Battery Support icon and press the SELECT key The GR8-1180 JLR diagnostic battery charger will immediately begin to supply power and the BATTERY SUPPORT screen will display a list of real-time battery data
	NOTE: BATTERY SUPPORT mode will not automatically move to next step. When battery support is no longer required, press the STOP button on the display panel (see Label 4) Select STOP when battery support is not required
21	RECOVERY CHARGE
	NOTE: Only use the RECOVERY CHARGE mode when the battery voltage is 9 volts or below. This will charge the battery for 1 hour. When the time has elapsed, use either DIAGNOSTIC CHARGING or PDI/STORAGE mode to complete the analysis of the battery (see the section on Battery Test Types (above) for guidance on when to use which mode) Follow steps 7 to 11 (as detailed above) to enter battery details, including:  BATTERY LOCATION (Step 7) BMS INFORMATION (If "IN VEHICLE" selected) (Step 8) BATTERY TYPE (Step 9) RATING UNITS (Step 10) BATTERY RATING (Step 11)
	Next, enter the following settings:  REQ. VOLTAGE -  For both AGM and Flooded Batteries, use the numeric keypad to enter 14.5 volts REQ. CURRENT  For AGM Batteries, use the numeric keys to enter 40.0 amps For Flooded Batteries, use the numeric keys to enter 50.0 amps CHARGE TIME (1)  Select the "Timed" option CHARGE TIME (2)  Use the alphanumeric keypad and type 60 MIN
	Select NEXT to continue
	NOTE: During the charging session, the GR8-1180 JLR diagnostic battery charger provides updates of the charging voltage, current, remaining time to charge and the amount of amp hours the battery received The GR8-1180 JLR diagnostic battery charger will not continue to test the battery throughout the Recovery Charge When the hour has finished the GR8-1180 JLR diagnostic battery charger will give 4 audible beeps to confirm the mode has completed
	Select EXIT to complete Recovery Charging
