how to tell if you can battery tend via existing cig lighter

[AWEInCA]

I am looking to get a battery tender. I know there are lots of threads on the subject, but I'm interested in using my existing cig lighter in frunk 2013 ST

Is there a way to tell if I can use it?

Is it safe to plug the tender into it without knowing for sure if it can be used?

That is not a lighter, and it is only powered when the key is turned on. I don't believe it can be used for a tender.

Open your frunk and look on the left side (as you're sitting on the Spyder). Under the black plastic cover you will see pos. & neg. battery terminals. These are hot all the time. I hook my battery tender to these terminals with alligator clips.

I use this adapter with my accessory plug in the trunk and it works just fine because the plug is always live. http://batterytender.com/cigarette-lighter-adaptor.html

A way to tell if your socket is always live is to plug something into it with the key off.

if you have a 2013 rt it is hooked to fuse 6 and is only hot when key is on you must move it to fuse 7 then it will be hot all the time and you can then use it to charge your battery with a tender hooked up.
