The scorpion uses 3 x 9 volt batteries, and because I use my Scorpion a lot, I opted to save money by buying 9 volt NiMH rechargeables. The ones I originally purchased served me well. They had 200 mAp capacity, and although sold as 9 volts, their actual voltage output was 8.4 volts. For the first two seasons, they held a charge for about 12 hours, allowing 2-3 hunts per charge. Then, the ability to hold a charge time started dropping off until recently, where they would hold a charge for only a couple of hours, even with a hot pac in cold temperatures.
My new ones I purchased have a capacity of 230 mAp/hour and an actual output of 9.6 volts. I tried them out last evening in the cold (5 degrees below freezing)and after about 1 1/2 hours still held nearly all the same power, judged by the number of beeps the Scorpion makes when you turn it on. It sure looks promising.
If you are planning to buy some of these, be forewarned that there are cheap ones available on line, in the 3-5$ range, and they are CHEAP! They don't live up to what they are advertised to. This is one situation where you should not buy the cheap stuff.
