Will it hold that charge parked outside all night in winter?
Does that happen when it’s 120 F. outside and the air conditioning is running on high?
"Solid state", so think BIG capacitor or some other non chemical device.
Temperature shouldn't matter much.
But if you've,played with big capacitors, you know what happens when you short them.
What happens in an accident?
In the lab @ college some 35 or so years ago, someone left a 1 Farad cap on the bench fully charged. My, less than brilliant, lab partner picked it up by the terminals. One in each hand. Took the full discharge across his chest. Survived it but got a free ride to the emergency room. Was hospitalized over night.

Indeed. Would really hate to be anywhere near an accident when it dumped it's load.
