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.
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.
Yes, you can charge a 500mA battery with a 1300mA charger.
No, the battery charger has to match the voltage of the battery it is to charge.
No, you can not charge a 3V battery with 12V charger.
Yes. The voltage of charger has to be slightly higher than the battery for it to be able to charge the battery.
No.
No.
No
Chargers don't care is the battery is used on a boat, a car, or whatever. What is important is that you match the voltage of the battery and the charger. Don't use a 12volt charger on a 24volt battery, etc.
With a 12 volt battery charger that is made to plug into a 220 volt circuit.
I recommend you use an automatic charger but if you do not have one and the battery is fully discharged then click the link and insert the battery capacity in mAh and the charge rate in mA to determine the amount of hours to charge the battery.
NO, a 12 volt battery cannot be charged with a 6 volt charger. To charge any battery, the charging voltage has to be, at least, slightly higher than higher than the voltage of the battery. Current flowing through the battery is what accomplishes the charging, and no current will flow at or below the voltage of the battery to be charged.
Connect them together in Series. Connect the negative post of one battery to the positive post of the other battery. Then connect the negative charger cable to one negative battery post and the positive to the positive post of the other battery.
Yes, you can charge a 500mA battery with a 1300mA charger.
Not by connecting them directly, that'd be too powerful.
You cannot charge a battery without a battery charger or having it charged by the alternator in your vehicle while it is running.
There is no only one way to charge it and that is with a battery charger. A 15 amp battery charger will charge it about as fast as it needs to be charged.
sure, you can buy a battery charger that will charge any car battery.
