hey, I was cruising around Make Magazine's site and found this:
http://www.instructables.com/id/Salvage-9V-battery-clips-from-dead-batteries/ (http://www.instructables.com/id/Salvage-9V-battery-clips-from-dead-batteries/)
its a really easy demo about how to make 9V battery clips from dead batteries. I will never run out of clips again!!!
just thought you all might enjoy it ;D
Sweet thanks man that really cool.
I like the added new idea of the strain relief.
Just make sure you're using safetygoggles when picking the dead battery apart. I had to spend a couple of hours at the doctor after the battery exploded right into my face and eye.
Have'nt done this since, battery clips are'nt that expensive.
I could have used this a couple of years ago when I was scrounging for 9V battery clips and extending little shorty leads on the one did have. Now I have a bunch from Mouser. :icon_rolleyes:

You got that right!
a couple of months ago, I was sitting at my project bench soldering and "BANG!" a 9V battery blew it's bottom out just sitting there not connected to anything. Scared the living $#!+ out of me. :icon_eek:
Neat...
Id rather spend $0.20 and just buy my clips. A lot less work :D
i used to do this and they are waaaay stronger snaps than what you can buy,they look cool too.
I have been doing this since pedal #1, but without the strain relief. I think I'll start incorporating that into the process.
It's a lot more work than buying one, but it helps keep the landfills a wee bit smaller.
Another earth-friendly tip: Use a non-toxic water based glue instead of hot glue. So far no problems with durability. It saves a couple Watts of electricity and avoids burnt fingers at the same time-double bonus!
This is the stuff I use (available at craft supply stores):

Yeah, taking apart batteries was never the safest thing, but for those of us who need to save as much money as we can, it's a pretty good idea.
I found a dead 9V sitting around the house today. Project for tomorrow!!!
Its a good tip for sure, specially for the times a battery clip is the only part your missing for a project. But again, remember to wear eyeprotection. I got some ugly burnmarks in my face, but luckily I wore contactlenses and I think that saved my eye..
never had a problem opening 9volts as all thats in side is a bunch of smaller batteries,theres no chance of acid getting out.
I did it on a Radioshack battery today and it worked great except the terminals didn't like the solder... I checked it with a continuity tester and everything is ok!
I'll be doing this from now on!

I have picked batteries apart without any problems before, and that was part of why I got so surprised when I sat there with my eye full of whatever it is inside them.
Im just saying.. Making your own clips out of dead batteries is a good tip, and the way I see it, wearing eyeprotection is also a good tip. Just for that one time something unexpected happens..
Been doing this for damn near 10 years. http://hammer.ampage.org/files/DIY-snaps.pdf
One bit of advice, though. The resulting snap will be a bit thicker than "standard issue", making things a bit cramped once you have a battery connected to it, to the point of making it impossible to close the back panel shut. I have found this to pose problems with 1590B-size boxes. You can make life easier for yourself with one of the "classic" red Eveready carbon-zinc style batteries. Slightly bulkier Duracells and similar will certainly last longer, but may not fit the available space. Of course, when it comes to 1590BB-size boxes, the space thing is a non-issue.
In general, the better quality the battery, the better a snap it makes. Cheap batteries tend to have plastic tops and bottom which do not take a solder joint particularly well. You want to use the batteries with fibre ends. Finally, keep a small file on hand to scrape away the chrome plating from the backs of the rivetted snaps, so they can take a solder joint.
Personally, I recommend having the two wires come out the middle in a "T" formation, rather than out the end. That will give you more flexibility with respect to placement.
Thanks for this man! That is a great idea. I love it.

Mark, I have been on your page countless times, and I never noticed this file. Go figure. Thanks for the tip about filing off the chrome! I will try that next time for sure. I never thought of that!
For those concerned about safety, I would recommend the safety glasses as well as some good gloves. I tend to just pry the metal cases apart with whatever tools are handy, and the sharp edges are pretty scary. Better to take 2 seconds to put on the gloves and glasses than to risk injury.
