I see: Not unplugging your unit when car engine is off can drain the car’s battery. So there is probably no internal logic to cut off. As no one see what is inside, what you can is to measure the bahavior of fridge at lower voltages and try to estimate/measure the efficiency as the voltage goes down with some power-meter and temperature sensor inside. Don’t ...

Yes deep-discharge batteries can handle many more cycles than 50 for flooded cell lead-acid batteries ( some barely survive a few ) But they still oxidize the plates with a thin coating from the calcium-lead plates over time from under-voltage. This can be reversed with very fast rise-time pulse charging, but otherwise, they will become high ESR and unable ...

Certainly it is possible. To get 550 A from a 240 V source requires about 30 amps. That would be a circuit comparable to an electric clothes dryer circuit. It requires a transformer, rectifier and a filter capacitor. There would probably need to be a provision for preventing the capacitor from drawing too much charging current when the device is turned on. ...

200A * 12V = 2400W So it would be in the realm of possibility from a 240V 16A socket. However a starter can require much more surge current than that, so if all you have is a 240V 16A socket, and a 12V 3600W DC supply, that would make a rather wimpy car starter. This is never done in practice because it makes no sense to buy an expensive, high power DC power ...

Would a cracked sealed lead acid battery be a safety issue? YES! It is a safety issue. The corrosive gel inside has started to leak (hence that white crust, similar to what can form on car batteries, especially the older non-sealed types). I recently had the misfortune to drip some of the corrosive gel from an old, small SLA battery similar to yours (I didn'...

Yes. It is a safety issue. Buy a new battery. Put that one in a plastic garbage bag to contain the powder. You can drop it off at the place where you buy the new one. They will make sure it gets recycled. Lead acid batteries are very recyclable (people will even pay you for old non-functional lead acid batteries). If you just want to get rid of it, you can ...
