Check Your Lights and Optics: May 2015 Edition


May’s “Check Your Lights and Optics” results:

Total dead optics found: 0/11

Total dead weapon mounted lights: 2/4

Total dead handheld lights found: 0/6

The WML is out of rotation. It’s eaten three batteries from three different manufacturers in the last three months. I am going to replace it with a Surefire knockoff that’s been going well on my other rifles for some time.

Speaking of, one of my weapon mounted lights finally ate its battery after about two and a half years. Time for a replacement, but a good reason to check.

All optics are a go, but I will probably change all of their batteries on my birthday just to be thorough. That’s going to be a lot of batteries. :\

How’d your gear do this month?

    All optics, all flashlights good to go. Really surprised by your WML problems. Mine is still on it’s first battery after a year. (Not used often but it has gone through a night shoot class).

    Do you lock-out your WML? (Turn the head slightly to break the circuit. This works on my older inforce…) That will help save your battery- a hair more? I doubt they have dramatic parasitic drain, but sounds like yours might for some reason. That’s why I’m curious if you do lock-out.

    On another topic: what do you think of the Extar Exp-556 pistol? I’ve always found it intriguing. Would love a review if you could get your hands on one.

    Oh yeah, get some rechargeable cells too!!

      My experience/knowledge of rechargeable batteries is limited, but there are some issues with rechargeable Lithium-ion batteries. (My experience with NiMH batteries has been fine.)

      First, most rechargeable CR123a LIon batteries are a little bit longer than standard CR123a batteries. They don’t fit in all of my flashlights.

      Second, why are they longer? Because rechargeable LIon batteries require special circuitry to prevent them from being damaged by overcharging them or draining them too much. This circuitry will cut off the battery if the voltage gets too high or low. This can be a problem in a light that you need to rely on. Instead of slowly getting dimmer as the battery dies, the light will suddenly shut off because the battery voltage dropped below 2.8V (or whatever Voltage the protection circuitry was designed for).

      I guess a person could use unprotected rechargeable LIon batteries to solve both of those problems, but I’ve read that unprotected batteries can explode.
