Trickle Charger Needed?

My '17 GLC 4Matic will very likely regularly sit unmoved in the garage for 5-8 day periods during this winter (in not so cold Washington, DC) and it will be abandoned for about 25 days straight mid-winter. When it is driven during this period most of the outings will be less than 15 miles r/t, with perhaps a couple of 150 to 300 mile road trips thrown in.

I never had a problem with my Saabs on this kind of routine, but this is my first year as a Mercedes owner. For my car, my batteries (sic), and my well-being would it be prudent to hook a trickle charger up until mid-March? If so, any recommendations about what charger is a good choice, e.g. the Mercedes one? And, what is the easiest way to hook a charger up on the GLC?

Thanks to anyone who has experience to share. And best wishes for 2017 to all the member who contribute to this forum.

I routinely use a trickle charger and while it's likely not required for your stated application, anecdotally I'll tell you it's better to use a smart trickle charger like ctek 3300 to improve the battery's life and minimize failure to start scenarios

Pull the Start-Button when you are leaving it for extended period - 25 days you will be fine - Roadside Assist put in your cell phone memory for any unexpected jump...

It should be fine but it would be better to get one to extend your battery life.

Removing the start button will reduce parasitic current drain??

can I use the 12V socket to connect the trickle charger ?

Hello All,

I plan to buy the geniune MB trickle charger to charge my 2017 GLC43 during winter. According to the manual of the charger, the charger comes with a 12V "male" adaptor that plugs into a "special" 12V socket on "specific vehicle" (e.g. ML class as stated in the manual) designed for charging.

My first question is ... does my GLC43 had one of those "special" socket (and where is it) ?

If not, is it safe to use the socket in the cargo compartment which I believe is "always on" (ie it is still ON when ignition is off".

Thanks in advance for your help.
