Default ‘17 L405 Td6- Battery Drain

Hello Rover Experts!

Quick issue recap and current issue-

RR non responsive to key fob, had to manual unlock and using the start button with out any result. Lithium 1500 battery pack wouldn’t jump it. Although it only had about 50% charge on tap. LR Roadside assistance sent tow truck for jump. RR struggled but fired up. Ran for about 5 mins turned off dead. Towed to dealer, new battery as dealer stated bad cell.

One week to the day of new battery, begin to start RR, alert on cluster - start vehicle battery low. Drove to grocery about 5 miles, turned off, and prompted again battery low start car. So I left it run while I was inside grocery. Once home and shut off not message displayed. About hr later went to get my wallet and roll up windows - message start vehicle battery low.

See attached video - it seems the RR isn’t shutting down all systems and going to sleep. I noticed this after I locked the car up, I peeked inside for not real reason and noticed it he low gear light was flashing as well as the terrain response mode lights were cycling every so often. About 3 hours later I peeked through the window and the low gear light is still flashing, however the terrain response lights are no longer cycling as they were in the video.

Any ideas greatly appreciated…

The battery replacement was $470 rip and I have a feeling my old battery was in decent shape.

Thanks in advance for input..

I have seemed to solve it myself… battery terminal not tight…. So removed it from post. Let it sit for 10 mins and attached and tightened all good for days now.
