I see all of them say it is not safe to store at over 140 degrees Fahrenheit (apparently a limitation of all lithium-ion batteries). Has anyone found a way to safely keep these in the car during the summer?

Weatherproof plastic container stored somewhere in the engine compartment?

In a sedan, I don't think the trunk compartment will get that hot. It isn't exposed to the sun. For other storage areas, you could come up with some kind of insulated storage like a thermal bag.

I use one of those small, thick-wall styrofoam coolers frozen meat is shipped in.

I have the opposite issue. Would like to keep one in my truck for the winter months when it is below zero.

I'm trying to think of the last time I had a dead battery in my personal vehicle. I think it was some time in the late 1990s, and only because the vehicle sat undriven for several months. I realize that sometimes [stuff] happens and you should of course be prepared for it, but most dead batteries are avoidable.

I guess I'm old school. I made up a set of jumper cables from some old welding leads. They are flexible enough in cold weather and fit in a 50 cal ammo box. I dont want another battery operated device, sitting around that doesn't get used. I would guess the battery in said devices only have so many charge and discharge cycles before they are no good. My cables are a very low maintenance item.

Wife got me a jump box from Harbor Freight a few years ago I think for Valentines. I’ve used it several times and it’s been incredibly handy. I plug it up once a month to make sure it’s topped off and it’s never failed me.

See the question mark?
Vehicles are different and some will have plenty of room up front to place one away from the engine.

I haven't thought much about the heat in the cabin. I currently keep mine behind the rear seat in the storage bin back there. I guess I'll get a thermometer and watch the cabin temps as summer approaches. If it seems like it's getting too hot, I'll probably try the storage box I keep in the bed. It's lockable but not tied down. I don't worry too much about theft. I've kept that storage box in the bed for 4 years or so with tarps, gloves, ropes and such and none have wandered off. Hell they could take the hole box in two seconds.
