There is not enough information. It depends on the type of battery: chemistry, cells, size.

What is the charging current and voltage of 12v 180ah battry?
That would also depend on battery chemistry.
Is it suitable to apply voltage 12V 30mA to charge 4V 750mA battery?
No, the charging voltage needs to closely match the battery or BOOM!
How much voltage comes out of a 12v battery charger when its charging?
A: If you means for a car it would be 13,68 volts minimum. But what is really important is the amperes out of it that is what is needed to charge a battery and that can be as high as 100 200 amperes out of the generator. Once the car has started the battery is no longer necessary to run it the generator and the regulator will just do fine.
Will changing the battery from 6v to 12 v affect gas gauge reading?
If it is in your car then no, why do you have a 6v battery in your car in the first place it should be a 12v.
How long time will be taken by the 12V 7Ah charger to charge a 12V 22Ah battery?
A charger designed for a 12 volt battery should not be used to charge an 8.4V battery. It is likely to damage the battery and in the worst case can cause a fire. There are some chargers that can be used with a variety of battery voltages and chemistries but unless you are certain that the charger is safe and effective on a different battery voltage, assume that it cannot be used.

That would also depend on battery chemistry.
Will any 12v battery charge work?
According to the magnitude of said current will be the time needed for charging. For there to be a current flow to the battery, the charger must provide a voltage (voltage) higher than the battery, this is the reason why we can not charge a 12V battery from another. Or at least, could not, as we shall see later.
What is the battery light on for on your Chevy Astro?
The battery light comes on when the charging system voltage drops below 12V. If your light is on all the time, have your charging system checked because it probably is not charging the sytem.
What is the voltage of a Yamaha maxim battery?
Battery type: YB14L Initial Charging Rate: 1.4A 10 hours Specific Gravity: 1.280 Voltage should be at least 12V DC
What is the difference between 12v 7ah and a 12v 7ah 20hr?
12v , 7Ah means its the capicity of Battery , if load current is 1 amp then battery runs for 7 hrs. AH = Ampere* Current. 12v, 7ah 20hrs its shows load current is 7/20 amp.
Can you use and charge and battery at the same time?
I kinda wonder that myself...I am running my 12v LED computer fan from a 12v battery pack from my Ryobi drill with the charging cable inserted into the battery...it says its charging, and my fan is running...So, I will see if it doesnt explode...fingers crossed...
Can you charge a 7.2V battery with a 12V power supply?
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. $.02 Ed N3SDO
How do you hook up 2 12v batteries to make 24v for a wheelchairAsk us anything?
An important proviso is that the Ampere rating of both batteries should be the same. Otherwise, the plate current of the smaller battery could be exceeded. If you hook the negative terminal of one 12V battery to the positive of the other, then the assembly will have an overall voltage of 24 Volts. Be careful when dismantling the set-up if you have to do for charging.
Is it suitable to apply voltage 12V 30mA to charge 4V 750mA battery?
No, the charging voltage needs to closely match the battery or BOOM!
Can you store a 12v battery on the ground?
yes but they should not be left out in cold weather and keep them away from any heat source or sparks like from welding etc if charging the battery the acid caps should be loosened to allow excess gas vent
Can you use a 12V 3Ah charger to charge a 12V 26Ah battery?
Yes you can. The charger has what is called a trickle charge and will need to be left charging at least overnight and maybe for two nights dependant on how little charge the battery has left.
Can a 12v battery be used in a 12v device?
the answer is yes as long as the device works on dc current and not ac current if you tell me what the device is i might be able to help further
