The battery had been previously been removed from its packaging. It seems to charge ok, but I will put a load on it and make sure it is not a used battery.

Fantastic flashlight! I'm an airline pilot and was looking for a portable, discreet flashlight that can easily be put in a full flight bag, yet has a high power, quality beam for doing "walk arounds". The Streamlight 74751 far and away exceeded my expectations (and they were high, after reading reviews). The flashlight has a very powerful (yet adjustable) beam in a very small, compact design (fits easily in pant pockets). Some of the main benefits that I think stand out and should be mentioned are: - Very powerful beam, especially considering its it's very compact size! (the entire light easily fits inside a pocket, unless you wear skinny jeans) - Metal housing, yet is lighter than it looks. - 3 beam brightness settings, in addition to a strobe setting. - Pressing the power button lightly (without "clicking" it on) turns on the light temporarily (momentary switch), then immediately turns off when you lift your finger off the button. I find this a fantastic feature for walk arounds when you're in and out of dark spots you need to illuminate, without the constant wear and tear of "clicking" on and off. The box includes the flashlight, recharging base (clamps the flashlight onto the charging contacts), AC power adapter (to charge at home, etc), and a DC car power outlet adapter. The latter 2 adapters plug into a universal socket on the recharging base. All in all, a fantastic flashlight that I highly recommend. Couldn't be happier with my purchase. The only down side is possibly the price, but then again, you do get what you pay for (which I've found out several times over with other flashlights).
