Australia 2011 Range Rover Sport SDV6 SE Fuji White
Computer Reset after Battery Change

Last Wednesday my 2011 RRS wouldn't start, flat battery. After a half hour on the charger it started and I drove to Galston about 45 minutes. Turned engine off and dash message comes up "Start engine immediately battery low". Rang LR assist and was given options but decided to drive to Concord Land Rover as the better option as car was running. At Concord LR battery came up OK so they wouldn't change it. (It obviously had a surface charge which they didn't test for.)
Next morning no go, so ring LR Assist again and they sent out an Allianz van with a replacement battery. Excellent service. Asked battery fitter if computer required a reset and he said probably not.
Anyway I have a GAP IID tool so did some checking on voltages and a computer reset with the following results.
New battery with no reset it charged at 14.7V, after computer reset the charge rate dropped to 14.1V. Both voltages after driving for about 20 minutes obviously with engine running. Note that the old battery charged consistently at 14.7Volts.
So clearly new battery would have been overcharging without a reset. Could explain a lot of early battery failures after replacement if no reset!

14.7 volts is ok if you still have problems then you need to look at your alternator, all the charging process is managed by the main ecu, this tells the alternator what charge to pump out when needed. Also a short drive will not charge a battery enough it has to charged for a couple of days to be fully charged.

The reason your charging value dropped was because you fitted a new fully charged battery.

Hi Flack,
But it was 14.7 with the new battery and no reset and went to 14.1 volts the lower voltage after the reset with no other change.
The GAP IID instructions say that the reset is to clear the data in the computer memory which is held from the old battery.

Words from the GAP instruction manual below:

"-Battery Replacement
>> This routine will reset the stored battery monitoring data.
>> Use
>> This routine is required after the battery is replaced."

Hi Zilch,
