2018 3.5 Considering battery replacement

Recommended Posts

Considering replacing the battery soon on my 2018 with 3.5L

The car isn't a driven daily. This causes premature battery failure.

 

Can I do this myself? Looks like reaching the negative terminal may be difficult but possible.

 

Is this just a unhook the old battery and hookup the new, like I've done with other cars?

 

Any hints, tips, suggestions like what battery to replace it with would be appreciated.

 

Thanks.

Probably following this procedure, 

 

 

If I hook up a 12 volt power source to the cigarette lighter would that work to preserve my radio stations and destinations when I unhook my old battery?

Make sure to check if your Edge's tray has room for a bigger battery.  Not sure about the newer Edges but the 11-14 could take the bigger battery even if they weren't originally equipped with it.  If I remember correctly, Edges with remote start already had the larger battery.

It has been confirmed in the forums that H6 & H7 batteries fit (Gen2). The battery tray has three holes for the bracket to allow to fit the different size batteries.

If going with a different size battery its best to reset the BMS using Forscan, selecting the size and type battery.

Not familiar with Forscan, is that a app? 

 

Where would I find it?

I found this method for BMS reset and will give it a try. Still interested in Forscan sounds like something I should have.

 

Thanks for the info.
