Convert Battery Lights To Ac Power

Use a wire cutter to strip about a half inch of rubber off of the tips of the battery s two wires.

Convert battery lights to ac power.

It is possible that the voltage of your switching module is too low to activate the leds string properly. There is no way the terminals could withstand that much power. Connect the wire in the lamp labeled with a plus sign to the battery wire labeled with a plus sign by twisting the two wires together. First off re connect the lights to the batteries and measure the voltage across the wires where the battery connections are.

Two cr2032 batteries should show a nomimal voltage of 6v or thereabouts. You can wire your existing light directly to the inverter. All you need to do is to determine the voltage v and current mah of the device. In this video i convert a battery powered led string of lights to run on 120 volts ac.

I then forgot about the project until the material arrived. Inverter the purpose of the inverter is to convert 12 volt dc power to 120 volt ac. Connect the wires labeled with a minus sign to each other as well. But if an electrical device doesn t need to be portable all the time it would be nice to be able to power it with ac and not waste the batteries.

Setting up the system. Again that would cook your batteries. I then completed the same step with the wire. 8 aas wired in series would produce 12v which would still require a 15a draw.

We use battery power to drive a lot of our electronics. When it was time to complete the conversion i simply removed the 4 aa battery packs and connected the line from the string of led lights that needed power on the wreath to the output from the power pack. So in this project i show you how to modify an old ac power adapter so that it can power your electronics instead of batteries. I use an old cell phone charger and an ac power plug from the reindeer.

Wrap electrical tape around any exposed wire. A 600 watt inverter should provide more than enough power for your light without quickly draining the battery. 180w is a lot of power. A 180w device would be drawing 20 amps out of a 9v battery.
