I have a Trustfire SST-90 that stays dimly lit through all modes of the flashlight. It uses 3 Trust ire 18650 batteries that are likely over rated at 3600ma. I fully charged the batteries after using that light, and had it sitting here in my room a few weeks. I picked it it up to use it and the LED was slightly brighter than a glow. I recharged all batteries and it didn't make a difference. If anyone has had the same problem or can tell me what to do, please let me know,
Sincerely, TippyA
