The battery charger can be used but it is not recommended. The battery charger does not have filtering on the its output like a power supply does. You will probably hear an AC ripple on the amplifier which will become very annoying when listening to the amplifier.

Can you charge a 5 volt battery with a car charger?

No, an automobile battery charger outputs 12 Volts. This is far too many volts to charge a 5 Volt battery. You would destroy the 5 Volt battery with this charger.


Can you charge battery from ac?

No, it must be charged with a battery charger plugged into 120 volts AC which converts it to 12 volts DC.


What should battery charger needle read?

That depends on the battery, and the charger. my charger has different settings for higher amps to give a faster charge or jump. A fully charged battery will show 12.6 volts. The charger will read it's maximum amperage if the battery is totally discharged. A fully charged battery will read 12.6 volts with a digital DC volt meter. If it reads 12 volts it has less than 25% charge.


How do you charge battery with ac power supply I have a 12 volt dc battery and im trying to charge it with a power supply rated at 0-40 volts 0-5 amps?

You should charge the battery with the proper battery charger. The battery charger should list what types of batteries, voltages, and charge rates (amps) it is compatible with. Make sure this matches the information on the battery to be charged. Using the incorrect battery charger can cause battery explosion, leaking, or fire.


How many watts does my 12 volt 2 amp battery charger draw?

Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts


How do you unplug a batery charger from a lawn mower?

A charger is hooked up to a lawnmower battery by attaching the red lead to the positive terminal and the black lead to the negative terminal. The charger is then set to 6 or 12 volts depending on the battery and turned on.


Can you charge a 6 volt battery with 12 volt charger?

No. A 12 v battery will actually have a charged peak voltage of 13.54v or 13.58v. A six volt charger will have around a max 7.5v voltage. The 6v charger will think the battery has peaked and will discontinue charging.


How much electricity does it take to charge a car battery?

No matter if it is a 6 volt or a 12 volt battery, the amount of power it takes to charge it depends on its "charge capacity", measured in ampere-hours. A 60 A-h battery needs half the amount of power to charge it as a 120 A-h battery. The amount of power you have to supply from a battery charger depends on how old the battery is and also on how old the battery charger is. The older they are, the more power they will waste during the battery charging period. Very roughly, a nominal 12 volt 60 A-h battery in good condition but "flat" requires about 5 amps of current supplied at between about 15 to 17 volts (which the battery charger unit should take care of automatically) for about 13 to 15 hours. When the battery has been fully charged and disconnected from the charger, its voltage should be around 13.6 volts when it is not supplying any load current. The electrical power needed to do that would be roughly equal to 17 volts x 5 amps x 15 hours = 1275 watts.


Charge a motorcycle battery?

Motorcycle batteries may be 6 volt rather than 12 (check this) and if they are 6 volts, switch your battery charger to 6 volts or you may damage the battery.


How many hours does a lawn mower battery have to be on a float charger?

A battery float charger is intended only to keep a fully charged battery from losing its charge. It will NOT work to charge a battery that is discharged or damaged. Check the voltage of the battery to be charged. Do not use charger if the battery voltage is less than 9.6 volts.


What is stronger a 1 amp battery charger or a 9v battery?

You cannot compare these two totally different things. As far as amperage the charger puts out more amps if it is an auto battery charger and also puts out 12 volts. If you are talking about a 9 volt battery charger then the battery may or may not be more powerful, it depends on how many mii-amps the charger is putting out.


Would an 8 volt battery charge on a 12 volt charger?

No chargers usually produce about 1.5 volts above the battery to be charged. By connecting a 12 volt charger to an eight volt battery it will boil the electrolyte in the battery.
