FAQ:

Q: What is a 12V battery used for?

A: 12-volt batteries are commonly used as car batteries. Most car batteries are lead acid 12-volt batteries. Alternators charge a vehicle’s battery and supply its electrical system with power. Some boats use a 12-volt battery. A portable 12 volt battery is usually sealed in a waterproof case.

Q: Does the voltage regulator charge the battery?

A: The voltage regulator sends the proper amount of voltage from the alternator to the battery to keep the battery charged. If the voltage regulator is defective, the battery may keep draining quickly.

Q: Is there a dual voltage regulator?

A: Dual Voltage Regulator LM78 / LM79 system class regulator module capable of AC and DC input voltage regulator output, the voltage regulator module comes with aluminum heat, can withstand higher power dissipation. The module has an output voltage stability, low ripple and good load characteristics and other advantages.

Q: What is the use of voltage regulator?

A: The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage. Such a device is widely used in motor vehicles of all types to match the output voltage of the generator to the electrical load and to the charging requirements of the battery.
