I recently got a 1.6w 445nm laser built by RHD, and it burned better the first two days I had it. I've been giving it about 10 minutes of runtime before recharging batteries(Due to decreased burning after a few minutes), and its had maybe 45 minutes of runtime since I got it. It uses 18350 batteries. Do these not fully recharge? How often do you need to switch batteries? I seem to get my best burning the first minute or two after the batteries have been charged.
Thanks
