I was worried about my 2016 original battery life and recently two events were of concern. First, the "no remote detected" message when seated, but detection occurred normally when the remote was held over the center console. The remote battery read 2.98v. Not good enough and a new remote battery fixed the problem. Second, the initialization process when starting was taking about double the usual 3-5 seconds. The 12 v battery read 12.33, which, according to a previous post here, indicates a 50% state of charge. Uh, oh. I connected my smart Battery Tender overnight which fixed both the low voltage reading and the slow initialization time- with no recurrence. So, be aware: cold weather brings out battery problems. p.s. -- my Harbor Freight multi meter has proved to be adequate for voltage checks.
