The 1.2V AA 2500 mAh Panasonic Eneloop Pro NiMH batteries are one of the best rechargeable AA size batteries out there for more serious tasks including higher current loads and use in low temperatures. Normally in our tests of AA size NiMH batteries we test up to 2.0A discharge and that is already considered pretty high current load, but this time we are going higher for the Panasonic Eneloop Pro to see what you can get out of them at 1.0A, 2.0A, 3.0A, 4.0A and even 5.0A… and this is form a single battery, not from a pack of 4 for example. You can check our initial test of the 1.2V AA 2500 mAh Panasonic Eneloop Pro NiMH batteries where we tested at 0.2A, 0.5A, 1.0A and 2.0A – our usual settings. The graph below is for the higher discharge currents we tested at and you can also see the results in mAh and Wh after that…

It seems that 1.2V AA 2500 mAh Panasonic Eneloop Pro NiMH batteries manage to handle really well up to 4.0A constant current discharge, managing to provide a little over 1500 mAh capacity. Going for 5.0A however significantly reduces the usable capacity in a constant current discharge situation at ust a little over 112 mAh before reaching the 1V output voltage from the battery. Do note however that in a variable discharge load with peaks to 5.0A for example the situation should be much different, for example using these batteries in a flash for a digital camera. So if you need AA size rechargeable batteries that can really handle high discharge current loads, not only peaks, but constant ones, then you should definitely look for the
