You need to know that 1 amp equals 1000 miliamps.

An 8 Amp hr battery would last approximately 106.67 hours with a 75mA current draw. This is calculated by dividing the battery capacity (in Amp hours) by the current draw (in mA) and converting the result to hours.

How much current does an iPad 2 draw to charge the battery?

This will be marked on the label on the iPad and its original charger.


Can you charge a 500mA battery with a 1300mA charger?

Yes, you can charge a 500mA battery with a 1300mA charger. The battery will only draw the amount of current it needs for charging, so it will not be harmed by the higher current output of the charger. However, make sure the charger voltage matches the battery's voltage requirement.


How many watts does a 48 volt battery produce?

To calculate the wattage produced by a 48-volt battery, you need to know the current (in amperes) it can supply. Once you have the current value, you can use the formula P = V x I, where P is power in watts, V is voltage in volts (48V in this case), and I is current in amperes. So, without knowing the current, we cannot determine the wattage produced by a 48-volt battery.


What does 8Ahmean on a 12 volt battery?

Amp hours is a battery rating. It means that this battery can sustain 1 amp for 8 hours up to 8 amps for 1 hour. Depending on what the current draw is on the load will determine the length of time the battery will last.


What battery would I use to run a 12V DC fan motor that has an input current of 6 amps?

That's a large amount of current for a battery to use. You may want to purchase a 12V marine battery or 12V deep-cycle car battery. Or you can use a car battery charger with a 6amp minimum output. The amperage rating for your motor is a minimum requirement. For your power source, use the highest amperage rating you can find. Whether you use a 10 amp battery or a 10 million amp battery, it [the motor] will only draw 6 amps. The voltage is a different story. Use only 12 volts DC.
