Battery Tender

SeandG42 · 11-17-2022, 07:43 AM

Was reaching out to see if others that live up north use tenders when their 240's are not daily drivers. Any models or ease of hooking up suggestions? Had my 240 since Halloween. Love it. Was ceramic coated yesterday. Pick up today!

That's what I used for my Elise back in the day

How long do you go without driving it, typically? My '04 Celica isn't my daily, and it can sit for weeks on end without getting started. But, it still does when I ask it to, and that's with a cheap EverStart battery from Walmart.

BMW (similar to Porsche) sells one of these CTEK units re-branded as "BMW":

I have been using one of these for the last 4 winters on my Boxster and they do a great job at half the BMW/Porsche price.

That being said - I wouldn't worry about battery discharge in just yet. Car is too new

I have had great luck with CTEK over the years. I don't use one now because I drive the BMW almost every day, but I used this one on my old Corvette that I didn't drive often. https://www.amazon.com/gp/product/B00CD44RQO
