Can a 12V LED light transformer charge a 12V battery

A 12V LED light transformer can charge a 12V battery, but it can only charge some of the battery, and it is impossible to fully charge.

The 12V LED light transformer is actually a constant current source because of the LED light.

It is not sensitive to voltage, and the current through it is very demanding, so the LED lights are driven by a constant current source.

Because the output voltage of this constant current source is limited, when the battery is charged to the same voltage as high, the battery cannot be continued to be charged, so the battery will not be fully charged.

The LED light transformer you are talking about is a 12V switching power supply, if so, it can generally replace a 12V charger! The current of the switching power supply is related to your charging time, but you must figure out how much charging current your battery requires, which can only be less than or equal to the rated charging current of the battery, if it exceeds, it is very likely to burn out the battery, and even cause a fire or the danger of **, for example, the output current of your switching power supply is 5A, and the maximum charging current of your battery is 4A, then it can never be used! If the battery allows charging greater than 5A, then it is fine, it just takes longer to charge!

Apparently. The transformer you use is an electronic transformer! And there is no short-circuit protection. I don't know what you're referring to (I'm lighting the LED light, 12VAC DC

Input. Transformer**) Why is the LED such an input. But one thing is for sure, halogen lamp transformers will definitely not be used here!!

What LEDs need is DC voltage and possibly constant current. But if you give a high-frequency AC voltage, then the LED must be broken down! So is it possible that your halogen lamp transformer is not **???

Summary. Whether the 12V battery can be charged with a 24V charger, hello dear, the 12V battery can be temporarily charged with a 24V charger in a short time, but the charging time is too long, the battery will be burned out, this is because the rated voltage of the 12V battery is less than the rated voltage of the 24V charger, and the rated voltage between the two can not be matched, if the 12V battery is charged with a 24V charger, due to the large rated voltage of the charger, if the charging time is too long, the 12V battery will be burned out. Hope it helps.

Hello dear, the 12V LED light can be used directly to illuminate with a 12V battery. The battery connection light uses the battery car battery, buy a few bulbs that are matched by the telecom closed bottle car (with the same voltage), connect a few in parallel as needed, buy a plug and wire that is the same as the charger, connect the wire, and insert the battery charging hole. Service time, time (hours) = battery voltage (V) * battery capacity (AH) * 80% power consumption (W).

With two wires, strip the plastic wire at the end and tear it off, and connect it to the positive and negative poles of the battery respectively. The other end is connected to the two electrodes of the bulb, and the bulb will emit light. However, it should be noted that the withstand voltage of the bulb should be the same as the power supply voltage of the battery, and the bulb will not light up if the voltage is too high; Too low a voltage will burn out the bulb.

The 24V LED lamp cannot be directly connected to the 12V battery, and the voltage will not light up if the voltage does not match, so you need to buy a 12V to 24V power converter to convert the voltage before you can connect the 24V lamp.

Each LED needs to provide a certain voltage of DC power supply to light up (the power supply voltage should be higher than its on-voltage), the power supply provided by the power converter can also become the power supply of the LED through a certain rectifier device, so that the LED can emit light normally (like the indicator light on most power strips), the power supply voltage is lower than its on-voltage, at this time, the LED will not light up at all because the voltage is not enough, the current is cut off.

LED lights are not like ordinary incandescent lamps, and the filament voltage is a little lower and you will see red light.

Solution: Buy a 12V to 24V power converter to convert the voltage, and the voltage can be lit up when the voltage reaches the 24V required for the LED light.

Power converter function:

The location of the power supply to the on-board electrical appliances in the car's electrical system. Its power comes from batteries, which are used to power on-board appliances, and its important function is to provide power for power steering, air conditioning and other auxiliary equipment. The other type is in the composite power supply system, which is connected in series with supercapacitors to regulate the power output and stabilize the bus voltage.
