Is it possible to replace the battery in my 2014 F type V8S myself? Or is there a reprogramming step that needs to be done by the Dealer.
I know that was the case with my BMW. The BMW dealer had to reprogram the car to recognize the new battery.
thanks...Richard

 

It's simple to replace the battery yourself, but if you want the ECO stop/start feature to still work, you will need the dealer to use their laptop to sync the battery to the ECO system. For most folks, it's a blessing if ECO is disabled.

 

could you explain this "sync" process please, I can't understand why any reset should be necessary.

 

From OzXFR's shop manual...
Others here have commented that this isn't really necessary.

See section 414-01 in this 490MB document, for more than you want to know about the battery system, for both 1- and 2-battery cars...

Do you think that this calibration would also be necessary if you disconnected the eco battery for a while and then decide to connect it back up?

 

Thanks so much Unhingd for your speedy response! As you say, defeating the stop/start function would be a blessing. I hate that thing. Do you know off hand if they employ a second battery for that feature or does the main battery support that useless feature. I don't drive my F type too often and yesterday we started off on a 100 mile journey. The Nav/audio/etc main display was very faint, also none of the functions, radio, audio, Nav etc worked. I stopped for gas after about 5 miles, still not working. However, 100 miles later when I restarted the car it all came back. That, together with the fact that the battery in my 2014 is the original suggested to me that perhaps it has some low/fluctuation voltage that messes with the Nav system, but still starts the car. Any thoughts.

Also, looking at the mods on your F type I may be hitting you up on this forum in the future. My track car, ( Roebling Rd, Palm Beach Intl, Homestead, Daytona, SEbring) has been a BMW 135 M sport with Dinan Stage 2 tune. I am very tempted, after getting rid of the BMW to track my F type and will be researching what mods I may have to make, if any. I'm brand new to this Forum as of today, and thank you again.

 

On the '14 and '15 models start stop has its own battery. If you open the lower rear compartment where the main battery is, you should be able to see the 2nd battery that is for the start stop feature. That battery can be disconneced by removing the ground cable, or better yet, remove it and the 15+lbs it adds to the car.

More importantly, since you may plan to track the car and apparently need a new battery anyways, look into the thread about the lithium battery upgrade for the main battery - switching to that and removing the start stop battery removed an unecessary 58 lbs of weight from the car. Many of us have done it with great results.

Likely your radio and sat problems were a function of a low battery, it can cause a host of problems with those systems. Luckily, once voltage is restored, you should not have any lasting ill effects.

 

Great Information! Thanks so much...Richard

 

Just a quick question, is there a preferred lithium battery brand that we should install in our cars?

 

Antigravity RS-30 is one many of us have used with good results. Approximately 50% more than the factory lead battery, so its not cheap, but very light, easy to swap in, plenty of power, and the reserve button in the event of discharge is nice. Very long thread about lithium group buy on this forum, we only saved $30 with the group buy vs. regular ebay price, so you didn't miss out.

 

+1 to everything Chawumba said.

 

Thanks for the info.
So assuming I may not want to go the lithium battery route, does anyone have any information/experience on what it would cost to have the Dealer install a direct replacement.?
. And any comments on aftermarket batteries such as at Autozone, , Advance Auto, Costco , etc. thank you.

 

The battery monitoring device which is the module that is bolted to the negative battery cable at the terminal monitors battery voltages for proper charging and functionality. Anytime a battery is replaced either the main or the secondary the we use the jaguar laptop(sdd) to reset the system so it knows a new battery is installed. As far as autozone etc i recommend interstate batteries. They always test above the cold cranking amps unlike many others on the market and you can get them across the us with a great warranty.
And yes leavingthe eco battery disconnected just sets a fault and disables the system. See many of them disabled by owners

 

Longshot question but I'll ask anyways. Do you know if the secondary battery is disconnected in a 2015 if you lose the window and radio function when the ignition is turned off. Usually there is a delay or the radio shuts down when you open a door. Mine is instant off when I turn off the motor but I've got the start/stop secondary disconnected.

 

Mine doesn't. My secondary battery is disconnected and nothing changed except for the start/stop
I don't even have an error message.

 

 

According to the service manual, the start/stop battery powers the rest of the car, while the main battery starts the engine. (Yeah, I'm nitpicking. )

 

 

I was wondering how start/stop works in 1-battery cars. I guessed maybe they use a supercapacitor to hold up the power bus, but Maxwell sells an 'ultracapacitor' which they say is used to start the engine while the main battery powers the rest of the car. That's one big capacitor...
