Must be the “DCS” spec
That handle is perfect, my battery has two bolts coming out the top. Does the handle come in different colors?
With use, it goes from silver, to red, to black.
The handle, or your skin?
no, but its colourchanging!
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.
I hear they’re bred specifically for these looks too
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.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.

Tell that to the person who wanted to be cheap and used a car battery.
Yeah, not worth the saved money…
Absolutely. I haven’t been told the final costs of the renovations yet but from what I’ve heard, they had to completely rip out everything from the room you can see in the background to get rid of the (lead-contaminated) soot.
Also, it was pure luck that everyone got out unharmed. I rent that place twice every year to spend a couple of days with friends who live all over Germany. One of them had all his stuff in the room behind the fire. The only reason he hadn’t been in there when the battery exploded was that the night before he hadn’t slept well on his air mattress and had moved to a couch upstairs. The room has a fire exit but depending on how fast he would have woken up, he might not have found it through the dense smoke.
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.
To add the little bit I know to the comments above.
Car batteries are not the same as AGM (often sold as scooter or marine batteries) or newer LiFePO4 batteries.
While I think AGM and car batteries both are lead acid, car batteries are designed to have one big discharge to start an engine and then recharge from an alternator. The other batteries are designed for a slower discharge over time.
The batteries commonly used in battery backups were usually AGM type, and now the LiFePO4 (usually used for solar) are starting to be used for backups and are much safer (I think they don’t off gas as much?). The original post was a picture of a solar battery, but an SLA (sealed lead acid, of which some are agm) one from harbor freight.

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.
At least it wasn’t sitting on concrete. The building would be leveled. /s

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.)
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
I’ll be the spoilsport for any youngins or otherwise clueless folks.
Don’t do this, very bad. Big spark, fire, bad time.
I don’t believe anything I read on the internet, so will go and do my own independent research.
You will need to jump-start your battery to reset it. Be sure to connect all four terminals for maximum power delivery.
Empirical research?
Merely monarchic
Shill. You obviously work for Big Battery!!
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.
I know lemmy hates AI…but man the tech jokes here are so damn deadpan they may as well be malicious training poison.
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
thats true for big capacitors
Those you recharge with your body’s electrical flow by touching both legs with one finger
So, I shouldnt insert a straw to relieve pressure
Not unless you’re thirsty
I have a bloated power bank sitting on my balcony (concrete) right now. Lowkey scared of transporting it for disposal.
Just return it to the ocean so it can spawn a new pod of AAAs.
Where do you think electric eels come from?
Need some red necks with some land. Then shoot that puppy with something big.
Also have a hog carcass nearby and film it.
Is that a lead acid battery?
How the fuck do you do that to a lead acid battery?
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.
Discharge it fully and freezing it can usually do it.
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
Yeah that’s what surprised me. I thought most of them self-vent.
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.
Shorting it out should do the trick.
You just don’t want to be too close when it sheds. They can be a bit testy for a while.
Should prob water it.
