Best Jump Box?

I didn't start my LC for a few days with the nasty weather outside and somehow managed to run down the battery so much that even the locks wouldn't operate. Pulled out the NOCO GBX 45, powered up the LC, and started with no issues. I'm not sure how I ran the battery dead, but the NOCO worked and I had zero issues getting the LC back up and running. Purchased a NOCO Genius 10 to charge the battery back up. The NOCO tests out quite well for charging the deadest of dead batteries. The onething I don't like is that the NOCO doesn't have a voltmeter to show the battery voltage. But, the Genius 10 is small, easy to use, and can be used on a variety of battery types. In addition, the Genius 10 also claims the ability to recondition/restore a battery (but, I'm always skeptical of claims by any manufacturer.)

I have the Genius 10 that I used to trickle charge my F-150 that was relegated to a weekend vehicle for a couple of years. Worked like a charm. I don't trickle charge the LC, as it's a daily driver and has taken over the weekend duties as well. I love the Genius though one has to watch those plastic clips don't break. My red clip broke on my charger and there is no way to replace that cord. It's not a huge deal but I don't click in the extensions now. They stay, but they're not locked. The GBX45 is in the LC storage cubby in the back. Hoping I never have to use it! lol

I picked up a noco gbx45 to keep in my LC250 and went through the LC owner’s manual as it is my first hybrid and am not sure how to jump it. The manual states to have a car attached to the LC and run the engine for 5 minutes before turning the LC on. Do you need to charge the battery with the noco or can you start the LC without any charge as long as the Noco is connected and ‘ready’!

I would not expect to have to put the GBX on the vehicle and let it sit for 5 minutes before starting it; but, I've also not had to test it, thankfully.

Like everyone else on this thread....I've now become worried about my starting battery. I've had no issues after 18 months -- but I live in Tucson which usually kills batteries in a couple of years. I currently have a GooLoo GP-37+ that was gifted to me -- but I am looking to upgrade. The GooLoo has had mixed results with other vehicles -- but definitely will not start a vehicle with a deeply discharged battery

From reading this thread, it seems the recommendation is for a Noco GBX45 or GBX55 -- or some other Noco product. I was just looking up the storage temperatures for the Lithium-ion chemistry -- Noco says 122 deg F max storage temp. Unfortunately, a vehicle in Tucson can get much hotter than that in the summer even in the shade.

So....I looked into some options....There is a line from Lokithor like the J1350 PRO that uses LiFePO4 chemistry that is rated to 140 degrees F storage temperature -- still lower than what you might encounter in Tucson, but closer. Does anybody have any experience with these?? Does anybody else concerns about straight Lithium battery storage temperatures??

Reminds me, I should check the charge on my Noco…. I’m not familiar with those pieces of equipment unfortunately. Good luck. Hot out there.

If you are concerned about temperature, then I'd get one of the super capacitor jump boxes. For the LC, you won't need anything terribly powerful because the jump box basically only serves to get the computers up and running. Once the computers are up, the LC uses the hybrid battery to start the car. I've had no issues getting my LC to jump off of my NOCO GBX 45 (and have even used the GBX 45 to jump a buddies completely dead battery on an older sedan.)

One of the members hooked up the Ancel BS 200 to his battery, which might be your best solution. Not only is it a capacitor powered jump starter, it also helps maintain your battery and keeps track of the battery state of charge (SOC).
