Hi, I've recently bought a NM 800. The batteries for it didn't arrive at the same time so I used an older battery in it until the new ones arrived. It had been working fine but between taking the older battery out, charging it and putting it back in its now only producing a dull beam even with the fully charged new batteries. I've made sure everything's tight and it's not just the setting its on.
I think I may have put the battery in the wrong way round at some point could this have caused damage to the LED or something resulting in a dull beam?
Has anyone had this experience?
