If you've ever had your flashlight fade in the cold, go ahead and hit that subscribe button. No, wait, that's GarandThumb's line. Anyway, we got good news for you: a chemically special battery that works in the cold!

How about a rechargeable 18650 battery that keeps working at -40°C / -40°F? Will do!
