Negitive battery spring bent

[Jspd6g]

Greetings

I have the cyber LZCB445-500 from lazerer. The negative terminal spring pushes over to the side every time I put the batteries in. I can stick my pinky inside and straiten the spring back out but once i place the batteries in and screw the tail cap down it pushes it into the same position. which in turn is causing the laser not to function.

I'm not sure but i suspect that the what every the spring is embedded in is loose? Is this something I can fix myself?

Have pictures of the tailcap?

hopefully this picture will help!

So this is the spring inside the laser towards the front. I thought it was the tailcap. Does the battery tube portion of the host unscrew from the head?

 

[Jspd6g]

No it's one solid piece

 

[Speedy78]

Some portion of that laser has to unscrew. It may be all epoxied together though. Maybe you can stick a pencil up in there and bent the spring back to the center?

 

[Jspd6g]

I can bend the spring back but i think the packing material under the spring is loose and that is what is causing it to bend over.

Might be able to pull out that foam piece. I would still try to figure out where it unscrews. It may need to be disassembled to be repaired.

Probably the spring broke loose from the solder joint causing to pivot/flop over easily

Needs to be resoldered to driver board

I am very new to all this and I thank you very much for your help. I can't for the life of me figure out how this would unscrew any further, I can not find any seams.

The only part that might look like it comes apart from the body is at the top where the beam comes out of. But it is recessed and I'm not sure how it would come out.

I'll take a pic of it

I don't know if this helps at all

Looks like the whole assembly was pressed into the host. Might be able to remove the rubber around the spring and then find a pipe that fits over the driver but into the host and press it out the front.

Cut it short , solder on it to give it a little strength..

Before you hack your laser apart, you might check your batteries. Maybe they are too big, or maybe there is a more suitable option that fits your particular laser better.

For example, 18650 specification states 18mm diameter, 65mm length.
16340 should be 16mm diameter, 34mm length.

Protected cells are the same cells, but with a circuit board tacked on to protect the battery. The circuit board will add several mm to the length. Some cell sellers will also add a button top, again, adding a few more mm to the length. It's not uncommon for folks to buy an 18650 only to find out that it's actually 70mm long, and is squishing their springs too much.

If your batteries are much longer than they should be, you might consider buying some different ones that someone's actually tried in that laser. If not, then these fine folks will help you figure out how to get at the guts so that you can snip the spring a bit shorter.

Cut out some foam so it fits snug down the barrel of the laser, with a hole in the middle for the spring to poke through. Provided it hasn't already cracked the solder joint or PCB, it should still work, and the foam will stop it bending.

I ordered the batteries with the laser but I will check it out when I get home tonight.
