In the product information it states an input voltage of 5 volts.
It will work with voltages between 3v and 5 v.

I've used three x 1.5v AA batteries connected in series to power something similar.

Product Description

Specifications:
Wavelength: 532nm (Green)
Input Voltage: 5V (3 ~ 5v)
Power: Less than 5MW
Outer Diameter: 13mm
Length: 55mm
Pattern: Line, Continuous output
Working Temperature: -30 degrees to 30 degrees.
Storage Temperature: -30 degrees to 60 degrees.
Pattern dot size: 10 ~ 20mm from 10 meters distance
Life: more than 3000 hours.

Any Li-ion battery would work fine for this module. It really depends on the size of the host you are planning on using, which battery would work best. It has such a small output that almost any single Li-ion would work electrically. You need to give me more information to be able to assist you further.

Exactly Paul !
A single Li-ion battery is enough and is rechargeable.

Here's my makeshift build using AA's which last surprisingly well.
I haven't bothered to build a better host using Li-ions since this does a great job for me.

So let us know what you want to use it for and we can help you further.

I'm using the line laser for alignment uses at work. I'm an assembler and I want to use it to aid in making certain parts aligned and level.

In that case you can use either a single Li-ion battery or a DC power supply that puts out 5 VDC. An 18650 battery would give you a long time between charges. It depends on how much you are willing to spend. I like the Panasonic batteries personally, but others are just as good. Here is a link for two Panasonic 3.4Ah batteries for $10.99 that are rechargeable, so you will need a charger for them also. www.ebay.com/itm/371690260837

Awesome, thank you. And I assume if I were to use a dc supply, I'd want it to be in the same current range as a AA/18650?

No, it doesn't need to supply nearly that much current. And besides, power supplies are not rated in Ah or mAh. They just have a maximum current level. In this case, A 500 mA 5 volt supply will be more than sufficient.

I've run this type of module on 3.6v (3x 1.2v AA NiCD) or 3.7v Li-Ion (18650 and 16340/18350).

Also ran them on my bench psu.. at 3-4v averaged around 35-45mw and a slight increase of current around 8.4v but huge increase in heat and the death of one module in less than 1.5min.. problem with these is it seems no two are identical in output so really just follow specs from particular vendor and keep it on the lower end of input voltage to keep heat down and duty cycle up.
