Typical Alkaline Battery Ratings

Also posted on the 8088 Networks site. I was using this to create a small external power supply for my Yeasu VX-3R. I used a 9v battery initially and realized that I should use a voltage drop to improve the battery life. Without any sort of voltage drop, the battery was dead in a little over an hour due to the fact that a full 500mA was flowing into the radio.
