Shannon Martin says just shake the battery and you’ll get DC.

Looking passed the absolutely insane answer here, no one has even brought up the whole issue of AC vs DC. Batteries are DC, while your fridge that plugs into your wall running on AC. I know they make DC ones, but it isn’t like they are interchangeable.

Just swap the leads back and forth very fast

Just run the rectifier in reverse, duh

There are DC-AC converters you can use (might be called inverters in English idk), which are pretty interesting circuits.
ColeSloth@discuss.tchncs.de 6 months ago
That part just takes an inverter.
I’m not sure of the max load output on a car battery, but with a 15 amp 1800 watt dc to ac inverter, you probably can run a fridge off one. It probably just won’t last all that long.

Funny thing, most modern refrigerators use DC motors for their compressors so that they can run at variable speeds, so there’s likely an inverter that you could bypass if you know the appropriate voltage. The DC ones for RVs are the same internals, just without the inverter.

Correction: they still use AC motors, but those motors don’t use line AC. It goes line AC > rectifier > DC > inverter board > variable frequency AC to run the compressor motor.

Have we moved to BLDCs yet?
DreadPotato@sopuli.xyz 6 months ago
No they don’t…they use AC motors and a VFD to control the speed.

I mean it’s probably labeled, right? How hard could it be?
themeatbridge@lemmy.world 6 months ago
Exactly. Find a hole that’s black and a hole that’s red, and stick some wires in there. How hard could it be?

(can’t answer, because she was fucking electrocuted)
