Fenix ARB-L14-1050 Rechargeable Battery

The steel shell gives it a reassuringly solid feel, and the overheat protection is exactly why I grabbed it for my everyday carry light. I've cycled it maybe a dozen times now and it still holds that 1050mAh rating without any hiccups.

Charging this up took no time at all and it’s held its juice through a solid week of daily flashlight use. The overheat protection gives me peace of mind when I’m out hiking in the summer, and 500 cycles means I won’t be buying another one anytime soon.

The steel shell gives it a reassuringly solid feel, and the 1050mAh capacity easily gets me through a full day of heavy flashlight use. The overheat protection is a nice peace-of-mind feature, and it's held up well through about a dozen charges so far.
