   The battery was charged when I received it and after installation, I used it and re-charged it. The replacement was a good as the original. The questions of longevity/battery life, of course, is yet to be determined. However I would recommend this product to anyone needing a battery for their flashlight

   Doesn’t hold as charge as expected, wish I could go with a Lithium battery so doesn’t need to be in charger all the time

   One of the battery sticks was damaged on arrival. One cell had a dent in it and whether or not the dent will affect the service life of the battery only time will tell. The battery was either damaged at the factory or damaged during packaging because the shipping container showed no signs of damage. The battery sticks are not a perfect fit for my standard Ultra Stingers even though Streamlight claims this battery fits both the Ultra Stinger and the Ultra Stinger LED. These battery sticks are slightly longer than the standard stick and prevent the end cap from being closed tight enough to be sealed by the “O” ring. See dented cell in picture and the end caps of my two flashlights. The end cap with the tape has an old standard battery and seals completely where the end cap with no tape has the new Nickle-Metal-Hydride battery and cannot be screwed down and sealed properly. My flashlights are no longer as tightly sealed as before and for this reason I give this product an average rating.

    This is a great replacement for the original Nickel Cadium battery stick that normally shipped with every Ultrastinger flashlight. I was looking for a replacement for my Ultrastinger after the original battery wouldn’t hold a charge anymore (I only had it 10 years since I bought it..lol). Anyway I read from other posts that this battery stick was recommended vs the original one because of the performance and battery life. After waiting a while for streamlightoutlet.com to ship it I was very impressed at the way it packaged in a protective plastic casing. I could say with absolute certainty that the dimensions of this battery stick are the same as the original so it’s guaranteed to fit. After having it for a few weeks I can say that it holds it’s charge very well and I have yet to actually fully charge it since it came full when I replaced the original for it. All in all it’s worth the money for such a quality part for your Ultrastinger.

    Perfect replacement for my old 77175 battery that came with my SL-20 flashlight.
