I'm new to this forum so Hi :⁠-⁠) I have a Hyundai Elantra (2020) that i recently had to do a battery replacement on (just outside the 3yr warranty, of course). Since it's my wife's car and we both work from home now as of a year ago the cars don't get used a lot. I'm wanting to make sure the car battery gets topped up. To that end i found a solar panel battery charger. However, the Elantra's 12v port doesn't connect with the battery when the car is off. I was looking at the fuse box panel to think about if there was a way to connect via there, and not energize something that shouldn't be. So, I was wondering if anyone else has had the same issue with needing to connect to the battery from within the passenger compartment, or suggestions on hooking up a battery tender.

Why not just use the ring terminals and run it just outside the grille area?

For an external hookup, yea, i could see that. I was wanting to hardwire the solar charger that will sit inside the car. Otherwise I'm not sure how to get through the firewall without drilling holes, which i don't want to do.

From other posts on here I've found the add-a-fuse idea using a micro2 holder. I'm going to need to investigate what ones are connected when the ignition is off but that might be how I'll go about it.

Ahhh, solar. That does change the game.

The add a fuse would be a great idea and alternative to drilling. Only think I would suggest is that the charger have a way to turn off when battery reaches full.
