Surefire Flashlight battery problem...

    My ED2 Defender (CR123A lithium battery's) and just to be on the fair side, Ive had the same problem with another brand of flashlight. If I screw the cap on all the way the battery life is only a couple of weeks.

    The only way I can get good battery life is to keep the cap on with only about 2 threads which means every time I need to use my light I have to screw the cap back on.

    Are you using Surefire batteries or some other brand? I have several Surefire lights (not the E2D Defender, though) and have never had this problem.

    The fact that it has happened with another light leads me to believe it could be the batteries.

    If it is the light, just arrange to return / exchange it with Surefire: they stand behind their equipment.

    Good luck!

    There have been a huge number of problems with cheap off-shore CR123s causing problems in various "combat lights". Some resulting in fires.

    If you're not using a set of "name brand" batteries go ahead and try a set of Sanyos or similar big name. If that doesn't work out send the light back to Surefire for work.

    The battery's are The Battery Station brand. I received 12 free battery's with my Surefire purchase form La Police Gear. The battery's are made in the US but they look like a generic product.

    I don't know... maybe they're knock-off's (?)

    those battery station cells have been the cause of many fires! if you are going to use them, you need to check the voltages and pair them up with like cells.

    remember, a cell that measures 3.2V is good, a cell that measures 2.7V is dead. use them together, and they WILL vent (explode)

    spend 10 minutes at www.candlepowerforums.com and read the sticky in the battery forum.

    Ditch those batteries asap! LA Police gear has been sending them out with the Surefires which have caused some problems.

    Get a name brand. I use Surefires and Streamlights and have never had any problem with either of them.

    Also, you should search on this topic: a forum member just had a G2 (I think) explode due to the batteries. He also bought from LA Police Gear.

    Hope this helps.

    Holy crap... I've seen the light! Seriously, the last thing I want to do is use crap battery's that might ruin my 100.00 fl let alone burn my house down.

    Is this problem just with flashlights? I think I have the same battery's in my range finder too.

    I'd replace those too...especially given the proximity of the range finder to your face and eyes, arguably one of the last places you'd want an explosion.

    Take care,

    I just got my Surefire flashlight from LA gear yesterday, and they sent me Rayovac batteries. Haven't tried them yet.

    Never pair partially depleted lithiums with fresh ones if you want to avoid problems. That goes for any battery type.

    Never use unknown lithiums if you want to avoid problems. Especially avoid any lithiums made in the PRC.

    "Problems" can include fires and explosions (more "pops" than booms) in the worst instances.

    Your not the only one who has had this problem.

    I experienced the same thing when I first bought my surefire E2D.

    The problem quite though after a while with me.

    I noticed in my Surefire 6P that the only batteries that lasted very long were Surefire brand. I have been buying Duracell, Energizer, Rayovac and they cost about 6 bucks a piece and lasted less than the Surefires I can buy for 20 buck per dozen.

    About your problem actuating your light (turning it on), is screwing the cap down the only way to operate it, or is there a switch?

    I had an explosion occur on an overseas brand on a Surefire z2 combat light
    while at my job, the lexan lamp cover blew right off but did not break and burned my left side a bit through my shirt. Only one battery exploded and not the other.
    It created a bang and plasma/heat effect. I put fresh batteries in and it still worked! But the lamp seemed weaker than before, no more overseas batteries for me.

    I was at a show last year when a Surefire blew on a guy's table. At first I thought someone had popped off a .22.

    After I checked around it was bad off shore batteries in a light that caused it to pop off.

    I hadn't been using off brands. However, that really drove home to point to me! To pop a $400 weapon light trying to save $1 or so is not smart!

    There is a tailcap push button switch. Unscrewing the butt-cap is a measure that prevents the light from being turned on, even if you use the on-off switch. I store and sometimes carry my e2e that way, to stop myself from accidentally turning it on and draining the batteries.
