Northstar 27F or any AGM Battery in 3rd Gen - Battery guy help !!

Hi all ,
the stock battery crapped out on my 2016 TRD OR after 35 months . I do not drive my truck every day , and sometimes it sits for several days or a week or more at a time before driving more than a couple of 8 mile drives to town when it is too cold for boat fishing .
I have been wondering with how to take care of a newly installed NorthStar 27 F battery in my truck . I am hoping to have it last for at least 5 to 10 years .
It is an AGM battery and pricey .
What charger maintainer are you all using if any ?

The Ctek Multi US25000 is the way to go...imho.
