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.
