My problems were batteries! Solved! I hope.

So, I have a few Wicked Lasers Spyder III lasers. The newer Arctic (it has continuously variable output and standby), the Krypton as well as the 473nm would cut off after a few seconds. I tried freshly charged batteries, different tail caps, newer batteries, to no avail. The batteries I had were old WL or new amazon specials. I came here and found threads regarding batteries and decided on 18650batterystore. I want to say, they delivered! I purchased a few different 18650s and a charger. They solved the problem. I have to give them props. I do not know how they measure compared to the other battery stores but I am satisfied. If anyone has experience with them compared to a better vendor, please post here. Thanks. I will post my purchases later.

18650batterystore is always my first stop for batteries. They are great, but lately their button top selection has been limited.

I use them for some lasers. No issues
