Can I change AC LED Christmas Lights Strings to DC?

My first year with LED Christmas Lights.

I know that LEDs are DC. But these work off of house current/voltage.

Is there a way to change them to DC, where I can connect them to a battery or some other power source? (Cut the plug end off or something?)

I have a host of LED Xmas lights up this year. Broadly falling into 2 types.

1. Power and controller (flash rate/pattern etc) in 1 unit - you'd need a DC-AC inverter to run these

2. Power adapter with the controller separated on the cable - look at the power adapter it should have a DC voltage and current (amps) spec on it.

Some of mine are rated at 24VDC at 150mA so I could run them off a 24VCD supply and not the adapter quite easily

I would just cut the plugs off and connect the strand to say... a weaker battery (I wouldn't suggest a car battery for this) and see how it is, but I'm a tinkerer so I don't honestly know if this will work. You could also try getting a DC to AC converter, plugging it into a battery and using that. We do that at my vocational for the LED's in the hallway powered by a wind turbine and solar cells.

It’s simple identify the voltage of each light as well as if they run series parallel or a series parallel hybrid, this will tell you how much voltage is needed to run the leds there may be enough in series that they require 120v to activate which case cut into smaller segments and run off relevant source, you can find out each lights operating parameters by either using a multimeter or ur preferred analyzing tool I’d actually start low and work up in voltage if u want do the oOoO method by hooking it up to random batteries to see if it works always start low so you don’t fry ur lights.
