Converting Battery-Powered Christmas Ornament


We have a beautiful battery-powered Christmas ornament on our tree. It lights up in shifting colors as many LED ornaments do. I won’t replace it for sentimental reasons. The problem is that the batteries are done after just an evening or two. It takes 3 small button-type batteries, of type AG13 or L1154/LR44 (quoting from the cover panel of the battery compartment). The batteries stack up in a compartment arranged like most AA / AAA battery compartments, with one contact on one end and a spring on the other. Is there a practical way to convert this to be wired into the tree light set, which runs off standard household power, 120V AC? My electrical skills are pretty basic. Thanks for any help.

Happy New Year,


Missouri, USA

The easiest way would be to install some fresh batteries and then take a meter and measure the voltage that is being put out. Then just find an AC to DC power supply that has a similar output voltage.

Those cells are 1.5 volts each so your fixture needs 4.5 volts DC. So, look for a 4.5 volt DC power supply (wall wort). When you wire your fixture to the power supply make sure you pay attention to the polarity (positive/negative).
