Sanwu Pocket Laser 445nm 500mw help with acceptable battery dimensions

Hello laser-loving people,

I just recently purchased a Sanwu Pocket Laser which takes a single 10440 battery. I am trying to find which batteries would work best with this laser.

There's a 4-pack of TrustFire 10440 batteries for about $26 CAD, but many of the reviews claim that the batteries are too long for some devices as they are 46mm in length. Would these batteries fit? This deal seems good because it comes with more batteries which would be convenient as the capacity is pretty low on 10440's.

Then there's also a 2-pack of PkCell 10440 batteries for about $10, these batteries seem to have the right dimensions at 44mm, but there are fewer reviews to rely on to determine the batteries reliability. This deal seems good because it's at least going to for sure fit as far as I know.

Any advice and help would be greatly appreciated as I'm trying to order these batteries so they can arrive at the same time as my laser. Just really trying to figure out if the 46mm's will fit.
