Stick with Original Equipment for the older SL-20X flashlight
"I bought this original issued brand flashlight to replaced some knock-off Chinese ones that I had purchased in the past only to find out that they don't last as long. The original one lasts longer and the light beam is actually brighter. Lesson learned. A bit pricey but it pays for itself at the end. Remember, this is for the older Streamlight SL-20X flashlights that require the fatter battery and not your more common skinnier but longer batteries similar to that of the Streamlight Stinger series of flashlights."
