Batteries
Although there are a wide variety of different batteries, in our applications, batteries typically provide direct current (DC) power from the battery to a motor or other electrical component or circuit.
 
The output voltage and output current is important when selecting a battery. If the device you wish to power using a battery requires 12 Volts of Direct Current (VDC) as an input then you must choose a battery that provides 12 VDC output. The output current rating of the battery is also important. If your device requires 12 VDC at 10 Amps you must choose a 12 VDC battery that can safely supply 10 Amps or more.
 
A battery must be capable of providing the correct voltage for your device and it must be capable of providing at least the current that the device requires. A device that requires 12 VDC at 2 Amps will work fine with a battery rated for 12 VDC at 10 Amps but will not work with a 12 VDC battery that is rated capable of providing 1 Amp of current.
 
Never overload a battery or under power a device. You run the risk of damaging the battery and the device.
