Should I be concerned about the mAh (milli Amp hours) rating?
Yes, but only when considering NiMH batteries. Alkaline batteries typically have a capacity rating of over 2,500 mAh and NiMH have rated capacities of only 1,200 to 1,800 mAh. But, when actually powering an electronic device like the ADVANCED TASER, the NiMH batteries will run the device for two to three times longer. Alkaline batteries were not designed to meet the very high power demands of today’s electronic devices. Alkaline batteries have a high rated capacity, but they can only deliver their full capacity if the power is used slowly. With NiMH batteries, the higher the mAh number, the longer the charge will last. Also, the higher the mAh number, the higher the price! A rating of 1200 mAh is more than sufficient and ratings of 1400, 1600 and 1800 just increase the length of the recharge.
