    People really shouldn’t be normalising battery obesity, smh.

    It’s not cute. Obesity really impacts their quality of life, and shortens their lifespan. It’s tragic, not cute, when they don’t fit into their caddies any more.

    Met a friend of a friend some months ago who customised electrical vehicles of all kinds, a battery like this blew up while he and his best friend were close to it. His friend died and he got burned real bad, the left side of his body is badly scarred and he lost fingers, hearing, most of his vision and other stuff on that side.
    We sat and talked for most of the night and after that I have a whole new “respect” for batteries. My mom uses an e-bike daily and I’ve made real sure she is aware of the possible danger. She used to store and charge the battery close to the door of her apartment, now it’s in a battery safety bag in one of the closets where it wouldn’t be in the way of getting out if something happens.
    Fucking scary stuff.

    I have a bloated power bank sitting on my balcony (concrete) right now. Lowkey scared of transporting it for disposal.

    This is NOT cute. Batteries only do this when they are in distress.

    (Sorry if I got the wording wrong, I couldn’t find the copypasta.)

    Need some red necks with some land. Then shoot that puppy with something big.

    Also have a hog carcass nearby and film it.

    Put it on a wooden shelf and let it sit. You certainly won’t regret it.

    This is the aftermath of a spicy car battery that was used as backup power for some emergency lights in a community center. Blew up in the early morning, burned the plastering from the wall and covered the whole basement in smoke and soot. Fortunately someone was there and heard the fire alarm, otherwise the whole building would have burned down.

      Do car batteries work well as a backup battery (not counting the explosion of course)? I assumed they would require an alternator or else they wouldn’t hold much of a charge. I know very little of cars obviously.

        A typical UPS (uninterruptible power supply) that’s used for computers/servers is basically powered by a small car battery (12v nominal voltage, lead acid battery).

        Sump pump battery backups are also typically a lead acid battery, though they’re typically a “deep cycle marine” battery, which basically means they store more energy than an equivalent sized car battery.

          Oh, this makes more sense. I never thought about a powered UPS as being similar to a car battery with an alternator.

            An alternator is actually just a small generator! It converts rotation (from the engine spinning a pulley) to ~13v to ~15v DC at up to some level of current spec (usually 50Amps or more). Some of that goes to the battery to charge it, and some goes to powering accessories in the car.

            A UPS simply has an AC to DC charging circuit to perform that function, converting mains electrical voltage (~120v AC in the USA, varies by country) to ~14v DC.

        They’re cheap, but fine. You should have a proper battery maintainer or smart trickle charger attached. A good one will tell you if there’s a fault with the battery.

    Here’s a tip Big Battery doesn’t want you to know: A cell can recharge itself by recovering the charges from the opposite terminal. Simply connect the two terminals together and wait 10-30 minutes

        Walter White did that to the inconsiderate sports car driver in breaking bad, took an aluminum windshield washer and laid it across the terminals and closed the hood and the car exploded.

        If you put a wrench across the terminals, it melts the wrench, along with maybe exploding.

        It’s not surprising llm models hallucinate so much, being principally trained on reddit, god help us all if people keep on trusting it so much.

        I think people are coming around to some degree though.

      Be careful with this. If it lets out the magic smoke then the battery loses pressure and won’t be able to power anything

      Overvoltage during charging might do that (water electrolysis happens, meaning that there’s hydrogen inside)

        Just add a little valve then for the water to leak out, not complicated at all. And something something it’s what plants crave.

      Having had a spicy car battery myself last weekend, due to inexistent voltage regulation, I would have expected that one to be able to vent the excess pressure. Sealed battery out not, it’s better not to build up pressure

        Do SLAs usually have vents?

        Car batteries, even maintenance-free ones, do…but I can’t recall seeing them on smaller SLAs like your find in a UPS or PowerWheels.
