I have a 1st gen SR Mini Intimidator that I bought a very long time ago as a gift for my father. He left the the flashlight in the truck a few yrs ago when it was probably -35c. Killed the batteries and the thing sat for a couple yrs. Fastforward and I bought a new set of 18650 Epoch Batteries that are 3500 mAh 10 Amp. They have a integrated protection circuit and are button top. I charged them up using a Nitecore intellicharger I4. Popped the new batteries in and the flashlight fails to cycle the medium, high and turbo modes but will still emit on low light mode and strobe mode. Iām just wondering if the led booster driver is faulty. The flashlight has not been used much and it would be a shame to not fix it. I doubt oolight will do any warranty work as I live in Canada and am outside the timeline.Any advice would be appreciated.
