NiMH rechargeable batteries hold a charge longer, can be recharged more times over their life spans, and have higher capacities than those made with NiCd. Duracell vs energizer Which is Best Battery? We charged the AA batteries at 500 mA and discharged them at 1,000 mA, which is the recommended rate for batteries of this capacity. As a reminder we are using constant current load tests with 0.1A, 0.2A, 0.5A and 1.0A for the 1.5V AA-size Alkaline batteries, so we are going to rate the best batteries in four different charts as we’ve seen that one battery that performs very well under low load may not be the best with higher load and vice versa…. It was unsurprising that several brands of batteries—from AmazonBasics, Energizer, and Panasonic—had nearly identical results in our tests.
