no. It can overheat the battery, damaging it.
Here is a separate answer: I just charged a 12v car battery using a 110v DC Welder set on 10 amps, and putting out 50v. I had to check the battery every 30 minutes for overheating, which it did not. I know this is not recommended as I risk damaging the car's electrical system and the battery, but I was in a pinch.
I only charged it for 1.5 hours, and there is a substantial risk that the battery will explode. I disconnected the terminals at the welder to avoid igniting the hydrogen that forms around the battery during the process.
Other risks include overcharging the battery because chargers designed for 12v drop to a trickle when the battery is fully charged, avoiding damage to the battery.
No
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
Depends on the amperage of the charger. A 10 amp charger will charge it in about 1 hour.
Yes
Yes as long as it is the right voltage: a 6v battery needs a 6v charger; a 12v battery needs a 12v charger. <><><> If you can set the battery charger's output to give either a 6 or a 12 volt output, then you must always remember to set it to 6 volts if you want to use it to charge a 6 volt motorcycle car battery.
Depends on the amperage you are applying to it. Read the charger manual.
The battery is a 12V car battery.
How do I read my 12V battery Charger Top dial reads 100% -0 Red Colour Bottom 0 2 3 4 5 ---------15 with a needle
240V household charger or 12V in car charger.
Voltage is the same but amp hour capacity of the car battery is much higher.
Yes, you can do this.
A trickle charger is a car battery charger that is designed to be left on a car for very long periods of time to re-charge that car battery by slowly adding charge to the battery.
