Do not do this it will damage the battery and could cause the battery to explode

Can a 12-volt solar battery charger charge a 36-volt battery?

No, a 12-volt charger cannot charge a 36-volt battery. The electrical potential difference across the leads of a charger must exceed the electrical potential difference across the terminals of any battery it is expected to charge. And 12 volts is much less than 36 volts.WHY?The 36-volt battery would require at least 39.3 volts to get to a float charge. This would charge the battery to 80% quickly, and then take a logarithmic period of time to finish the battery. To actually charge the 36-volt battery correctly would require roughly 43.2 volts, but if we can't get 39, this is irrelevant.The 12-volt charger has no chance.The answer above is correct; there is no way the 12-volt charger can charge a 36-volt battery. However, the voltages given apply only to lead-acid batteries. They would be different for nickel metal hydride or lithium cells. You still need a charger with more voltage that the battery voltage in any case.


What is a 3 volt battery?

A 3 volt battery is a battery that produces 3 volts. Many watch batteries produce 3 volts.


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 a 6 volt battery with a 12 volt battery charger on slow 2amp charge?

No.


How many AMPS will a 10 AMP 12 volt charger charge a 36 volt three battery in series system with?

A 10 amp charge will only output 10 amps and 12 volts. So, if you want to charge thee 12 volt batteries hooked in series you will have to disconnect the positive cable from each battery and charge then individually. You cannot charge three 12 volt batteries hooked in series. That requires a 36 volt charger.

Can you charge an 8.4 volt battery on a 7.2 volt battery?

No. It requires more that 8.4 volts to charge a 8.4 volt battery. If the 8.4 volt battery is discharged to less than 7.2 volts then it might charge up to 7.2 volts but no higher. Once the voltages are the same then current stops flowing and charging stops.


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.


What is the initial voltage of a car battery?

A fully charged 12 volt automobile battery will read 12.6 volts with a digital volt meter. It will read 12.4 at 75% charge, 12.2 volts at 50% charge and 12 volts at 25% charge.


How do you check a 12 volt battery for adequate cranking capability?

A fully charged 12 volt battery with engine not running, ignition off will read 12.6 volts at 100% charge. 12.4 volts at 75% charge. 12.2 volts at 50% charge. 12.0 volts at 25% charge.


What is the minimum voultage for a car battery?

As read from the battery with a digital volt meter with engine off. 12.6 volts = 100% charge 12.4 volts = 75% charge 12.2 volts = 50% charge 12.0 volts = 25% charge


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.


How much voltage should be used to charge a 7.4 volt battery?

7.4 volts.


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.


How many volts are present in a fully charged 12 volt car battery?

12.6 volts at full charge. During charging at least 13.8 volts are applied to the battery.


What happens if you charge a 12 volt battery backwards?

You cannot charge it connected backwards. You will destroy the battery.


Where do you find the reading of voltage of car battery?

All automobile batteries are considered 12 volt batteries. At the battery itself. With a digital volt meter set of the 20 Volt DC scale you should read 12.6 volts on a fully charged battery with the engine not running. You will see 12.4 Volts at 75% charge, 12.2 Volts at 50% charge and 12 Volts at a 25% charge. With the engine running you should read from 13.5 to 15.5 volts if the alternator is working properly.
