New Battery in a Discovery 4

[Bundus]

When I collected my 2nd hand Disco I found it with the battery dead. Replacing it with a new Probe 100AH battery was a no brainer. Now I hear that the new battery has to be registered with the cars system. Is it necessary? How is it done, resp. can I do it? The next LR dealer is more than 100km away. Thanks for advice!

What year is the vehicle, is it 3.0l or 2.7l?

If it is 2.7l you will probably be fine,if it’s 3.0l yes it needs to be done.

Most battery suppliers can do it these days.

not so much registered. you just need to reset the 'smart' BMS so it knows it's charging a new battery as it's slowly adjusts it's charging cycle as the battery ages and capacity is reduced. you can do it with an IID tool or I think you can also do it just by shorting the car terminals. Disconnect the battery and bridge the +ve and -ve leads from the *CAR* (NOT THE BATTERY... OBVIOUSLY). this I believe will reset the BMS.

You cannot do anything but a “hard reset” (think reboot) by shorting the cables.

The BMS requires a tool

Will nanocom do this?
So this is for d3 & D4 or just d4?

Yes it can. Applies to 3.0s

In D4 2.7s you can set the battery type and size to optimise charging.

In D4 2.7s you can set the battery type and size to optimise charging.

Wow
Can we have today’s comfort with yesteryear simplicity ?

So presumably GapTool can do the same for a 2.7? If so, care to point me in the right direction as my elderly brain does not recall anything from reading the ops manual (in almost one continuous session).

You know, I just took the old battery out and put the new one in.

I checked the Land Rover manual and there’s nothing about having to reset the battery management system.

Just because the manual doesn’t tell you, doesn’t mean the BMS doesn’t exist and doesn’t mean the ECU isn’t tracking your batteries ageing. You have a 2014 so it is a factor in the long life of your battery. Sure you don’t have to do it, but I’d suggest it will treat your battery as an aged battery and mistreat it.
