There is a big difference between a power supply and battery charger. A power supply provides power to an electronic device, while a battery charger charges a battery. A power supply converts AC or DC into low-voltage DC, which is then used to power an electronic device.
Power supplies can be used with batteries, but they will not charge them; for that, you need a battery charger. Another difference is that power supplies typically have higher wattage ratings than battery chargers.
How does a lead acid battery charger differ from a power supply? A battery charger is a type of power supply. After all, what is required is to convert the AC power to something suitable to charge a battery. Eliminate the bells and whistles and what is left?
Power supplies are devices that convert one type of electrical current into another, typically from AC (alternating current) to DC (direct current). They’re often used to power computers and other electronic devices. Power cords, on the other hand, simply carry electricity from one place to another.
Once you have confirmed that it is safe to use your power supply as a battery charger detailed, connect it and begin charging. Be sure to monitor the charging process closely and disconnect when finished. Overcharging can damage both your power supply and your battery, so it’s important not to leave it connected for too long.
A power supply is a device that provides electricity to an electrical device. It converts one form of energy into another, typically converting AC (alternating current) into DC (direct current). Power supplies are used in a wide variety of electronic devices, from computers and servers to cell phones and tablets.
