I looked on-line for what was available that would have some legs to it so I wouldn't have to keep turning the camera on and off all of the time; thus missing all of the great shot. If I had a nickel for every time..........
"Oh son! Can you do that funny thing again so papa can record it on the video camera? Make sure not to hurt yourself this time."
After thinking about it for a while, I came up with the idea of making my own battery!
After reading Tim Anderson's Lost Your Charger? How to Charge any Battery Survival-Style, I decided to make an instructable of how I did it.
WARNING: Just because I have not blown up my camera yet with this external battery pack, doesn't mean you won't blow yours up. If you do create a battery pack such as this, and you do blow up your camera, it isn't my fault! I didn't tell you to do it nor did I twist your arm about it.
Step 1: Specifications
My camera's external power supply has an output of 8.4 volts and 1.5 amps. Rechargeable batteries put out 1.2 volts. After some high powered calculations, I found that 7 rechargeable batteries would put out exactly 8.4 volts! What luck.
I wasn't too worried about the current output of the batteries. They are 2500mAh and hoped the extra current would not burn out anything in my camera. (So far, so good!)
By looking at the plug on the external power supply, I was able to find the polarity being delivered to the camera. In my case, the barrel is negative and the inside is positive. This is important to know when you wire up your new plug and hook it up to the battery pack.
I also matched the plug from the external battery pack. It turns out that I have a size "H" coaxial.
