ok this is my first instructible so bear with me , i made this on such short notice because i needed a Power source to use on camping trips so i hope the time i spent on it helps somebody since i didnt have a box t put it in so I used Electrical tape

plus i also can use it when the power goes out i can use it to charge a Cell phone or run the light that i Have Taped on it

materials needed
Sealed Lead Acid Battery (From An Old Dead UPS I already Had, i think its a 7Ah But im not sure )

14-16 Ga Wire (Wally world)

cigarette lighter or Aux power outlet (Wally world)

12v Light (Bass Pro Shops $16.49 )

Note: Use Common sense, make sure your connections are good I am NOT responsible for any Damages due to Shorts, reverse polarity (Fried Electronics in General)......................

And Im sorry that some of my pictures are poor thats because my camera's battery died and it would have taken too long to charge so i had to use my cellphone camera

Step 1: Battery

Since I Already Had My Wiring Made ILL skip that step.
prep your battery
For wraping tape it works best if you turn the battery on the side that you wouldn't be using or have someone hold it for you.start with your aux outlet and switch. wire the Aux outlet directly to the battery then connect your wires to the switch for other opitional accessories like a Light or something

Step 2: Wiring

Well this one is self explanatory I've written a wiring diagram for it

Step 3: Finshing Up

With everything in place and taped on (temporary) test it with cell phone car charger
Then add an Inverter too

Future Improvements:
Put the Battery in A Box
Mount the AUX Socket,the switch &the light in/on the Box
Maybe A Solar Panel http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=41144
And Charge Controller http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=96728

Plus I didnt have to recycle the battery just the old dead UPS components
