I came across some 9v lithium batteries out of defibrulators that have never been used. They get changed out once a year just because they want to be sure the batteries are fresh. These guys are fully charged and get sent to the recycling depot when changed out. I got a few of them to try out. I picked up a $4 step down regulator off of Ebay and used it to bring the voltage down to 3.6v external power and then put a set of lithium energizers in the camera. Everything works good so far and nothing heated up or burned down so I'm going to set it up this weekend to see how long this thing will last out in the elements. -40's weather here for the last week or so but it's going to warm up this weekend a bit. Should be a good test to see if they can handle the cold. I hope these guys last a long time. The best part is they are free!!  [smile]

What's warm up to you? Minus 20? [smile]
Let's hear how they work. Seems to me someone awhile back had talked about them too.

Yup supposed to get up to -20 this weekend and then up to -6 by Monday. That's all Celsius temps. Still cold no matter what scale you use. LOL!! I may set this up close to home so I can check it out easily. Got a nice spot in the pasture where the deer are going through the fence.

Well here's the update.......they suck.... Good thing they were free. Couldn't get more than about 2-3 weeks out of them. Guess they are made for a few quick short bursts of power and that's it. I have another battery I'm working on now. Sealed, no leak 12v with that step down regulator. May work better.....but then maybe not....LOL!! [wink]

Sorry it didn't work out for you. Side note, the internal defibrilators (ie. one inside me) have a battery that lasts approx. 7 years before they have to swap it out and it WILL give more then just a couple "jolts". [bawl]

Careful some homebrew builder out there looking for a long term cam may want to excise that battery from you!!

Over my dead body....err wait, that might not be a good thing to say. I might have guys lining up to remove it for free for someone. See them with a sledge hammer for anesthesia and kdornskis dull knife to cut with.

Ken, you've met me, do you really think I can bench press THAT much? 50# is about my limit and imagine one of the arms weighs more then that!
And to the muscular toothpick post I'll have you know that I've been bulking up. Went into the hospital at 132# and left at 128# but in doctors office today am up to 134#!!

Just reading this, wondering how Gumby's other 12V battery test worked.  Is it still going after 6-7 months?

The battery is not the problem.  That step down regulator is the problem. They are only about 20% efficient.  You would be much better off designing a small PCB with a LDO regulator on it and a 100uf 16v Capacitor.
