disconnecting negative while away

[bgddydg]

Hello, I have a 2019 jl rubicon and am going to be away for a bit... it won't be driven, just wondering if ok to disconnect negative terminal while gone, I do have a tender but am spooked as no one will be checking on it and don't want a fire in any case... thanks for info in advance!

My $.02? By disconnecting the negative cable you'll stop any parasitic battery drain but I think you'll also re-set the vehicle's on-board computer but that should not be an issue. Others with more experience can comment specifically on that.

But, I've used battery tenders on many many vehicles over the years with no issues. In fact I'm using one now on our '10 Liberty as we don't use that vehicle often.

Agreed. I have been using (actual brand name) Battery Tenders on my Polaris and Harleys for over 20 years. They are always plugged in when I'm not riding them, with no issues at all. My Jeep is now garaged for the winter, and is being maintained by a NOCO Genius 10. Two months- so far, so good!

My advice? Stick with high-quality units. Don't risk fire just to save some $$ by buying some cheap brand. Also, to avoid the chance of a battery clamp slipping off while in storage, buy and install the permanent quick-disconnect harness on your Jeep. They are cheap, and make a good "permanent" connection that you don't have to worry about.
