(More customer reviews)I bought two 4-packs of these Delkin AA NiMH batteries based on their claimed capacity of 2900 mAh. As soon as I received them I charged them up using a pair of LaCrosse BC-900 battery chargers in TEST mode. According to the battery charger LCD screens, none of these Delkin batteries would charge up more than about 2050 mAh. I contacted the company I bought them from about their lack of stated capacity, and they replied that NiMH batteries need to be drained and recharged several times before they develop their full capacity.
I have since drained each set of four AA batteries in my digital camera and recharged them several times. I saw an increased capacity in most of the Delkin AA batteries up to around 2350 mAh. But there's at least one AA in each four-pack that gradually loses its ability to accept a charge. I have now had to return two of the eight Delkins for replacement. Kudoes to the company for promptly replacing the defective ones, but I'm chagrined that defective Delkin NiMH AAs would be so common. With a failure rate of 25%, I won't be buying any more Delkin products.
