The 1.2V AAA 1000 mAh GP NiMH batteries we test here are of the standard NiMH type and are rated at 1000 mAh typical capacity and 930 mAh minimum guaranteed. Our experience so far with GP batteries has shown that some models are performing great while others not so well, so it will be interesting to see to which group we can add these batteries. So time to start the testes…

As we usually do we have started the test of the 1.2V AAA 1000 mAh GP NiMH batteries with a low constant current discharge rate of 0.1A and the result we got was 1085 mAh and that is pretty impressive for a battery rated at 1000 mAh. Going further with a load of 0.2A and we managed to get 1005 mAh which is still over the typical rating of these batteries, and with even higher load we still manage to get good results, though not that impressive as at 0.5A we are are a below the minimum rating. Still we are seeing very good performance from the 1.2V AAA 1000 mAh GP NiMH batteries.

The performance of the 1.2V AAA 1000 mAh GP NiMH batteries in our tests:

– 1085 mAh at 0.1A load
– 1005 mAh at 0.2A load
– 876 mAh at 0.5A load
– 796 mAh at 1.0A load

– 1.325 Wh at 0.1A load
– 1.211 Wh at 0.2A load
– 1.029 Wh at 0.5A load
– 0.874 Wh at 1.0A load
