You can try to charge two 12 V batteries at the same time . Using a series circuit, place both batteries next one to another, and connect the negative pole of one of them to the positive pole of the other. Then use the remained poles to connect to the charger. The only other way possible, is to change the transformer, but this would be as expensive as buying another charger.
What else can I help you with?
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.
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.
Can 12 volt charger charge 3 batteries wired in series?
No, if they are wired in series you have 36 volts assuming each battery is a 12 volt battery. They will have to be wired in parallel to output 12 volts. In that case you can charge them with a 12 volt charger but it will take 3 times as long as charging just one 12 volt battery.
Can a 12 volt battery charger charge your battery?
A twelve volt charger will charge twelve volt batteries only unless it has a feature that allows you to change the chargers voltage. But on fast or slow charge 12 volts is 12 volts so most 12 volt chargers are only good for 12 volt batteries.
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.
Can you charge an 8 volt battery with a 6 volt charger?
Some have a switch for 6 or 12V - if not you will "cook" a 6 volt battery using a 12 Volt charger
Can use 14.4 volt charger to charge 18 volt battery?
Charger Output Voltage versus Battery VoltageNO, the output voltage of a charger must be greater than the rated voltage of the battery, usually at least one and a half to two volts difference.
Can you use a 9 volt charger for a 6 volt battery?
This is not advised! The 9-volt charger might have a current limiter so that nothing burns up, but it any case if left on it will destroy the 6 volt battery by overcharging. A 6-volt charger is not expensive.
Can a 7.5 volt charger be used on a 9 volt appliance the appliance is a weighing machine?
No. The voltage of the charger's output is only 7.5 volts. This is not high enough to charge a 9 volt battery device.
How many watts does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
How long should you charger a 7.2 battery with a 9.6 volt charger?
You do not charge a 7.2 volt battery with a 9.6 volt charger period unless you want to ruin the battery. You charge it with a 7.2 volt charger.
Can you charge an 8 volt battery with 6 volt charger?
No, you cannot charge an 8 volt battery with a 6 volt charger. The voltage of the charger must match the voltage of the battery.
