I have experienced 2 sudden dead battery incidences in the past 2 months. The dealer has replaced the batteries after the last incident. I got a Lithium battery tender but I am unsure where to attach it under the hood becase the battery is not visible. If anyone can provide a photo of the attachment points, that would be very helpful.
Regards

 

There should be points marked under the hood for that, a red positive and not far from the red a black point for the negative. Check your owner manual. Here is a link to a video showing the points in a 2020 Range Rover and it should give an idea what to look for. 2 batteries in 2 months is an indication that something is wrong. I would have the dealer check it out to determine the draw source.
