Yes, you can, but you need to put a resistance in series with the battery to limit the maximum current, so you don't overheat and cook the battery.
I tend to fast charge my batteries using a 12v light bulb / utility light to lower the current. The bulb will glow when the battery is taking heavy current, and as the battery builds up charge, the current will drop and the bulb will get dimmer and dimmer.
I try to limit the current to 1/10 of the capacity of the battery Im charging if I can.
Otherwise, I monitor it with an ammeter and voltmeter and watch the lightbulb.

How can you power a 12V car radio from a 110V wall outlet?
You will have to purchase a power supply with a 12 volt DC output capable of handling the current draw of the car radio. Try "google" to find the manufacturer's specification sheet for the radio. In the specs. will be the amp draw of the radio. With this information you will know what amperage the output of the power supply needs to be.
Can you use 12v 500mA adapter to tv antenna that has 12v 200mA?
YES!If you have a TV antenna amplifier rated at 12 Volts and 200 milliamps, you can use any power supply that will deliver at least 200 milliamps at 12 Volts. The important item is to keep the 12 volts at 12 volts. note: 200 milliamps is 0.2 amps. Even if you had a power supply that delivered 2000 amps at 12 volts you would be OK as it will only draw the 200ma that it needs.
Can you charge a 6v battery with a 12v charger?
No. The battery will be charged at a rate which is 2* the normal rate. This will cause the battery to overheat which might cause it to explode.
Can a 12v battery be charged by 6v supply?
No, you need at least 12v to charge 12v. Most alternators charge at 13-14 volts.
Can you charge a 12v lawnmower battery with a 12v car battery?
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
Can you charge a 12V battery with a 24V battery charger?
No
How you convert a power supply into 12v DC?
DC 12V power supply can convert 110/220V AC power source to 12V DC.
What power tools will the Makita 12v battery work with?
The Makita 12V battery will work with many different power tools such as the power drill for LCT208W. The Makita 12V battery is primarily for power drill tools.
Can you charge an 18v battery with a 12v charger?
No.

No
What can a 12v battery power?
Anything needing 12V to operate.
Can a 12V motorcycle battery charger be used to charge auto battery?
yes
How much power would it take for a 20 watts solar panel to charge a 12v battery?
about 500watts/meters of irradiance
Can a 12V 3.5A lcd monitor be replaced with a 12V 4.5A power supply?
Yes, you can replace a 12V 3.5A power supply with a 12V 4.5A power supply. The higher amperage rating means the new power supply can deliver more current if needed, which can be beneficial for electronics that may have varying power demands. Just ensure that the new power supply has the correct voltage and polarity to avoid damaging the monitor.
Can a 12v solar panel charge a 12v battery?
If the 12 volt solar panel output voltage is always higher than the 6.5 watt battery voltage. To charge a battery, a voltage greater than the battery must be applied to the battery, otherwise the battery will try to charge the charger.
