The 1.2V AA 1800 mAh GP Rechargeable NiMH batteries are a middle range rechargeable batteries from GP with a typical capacity of 1800 mAh and a minimum one of 1750 mAh. These are sub 2000 mAh rechargeable batteries they will probably have a hard time at our 2A constant current load test, but they should handle well at lower rates. Since we just tested the slightly lower capacity 1600 mAh model from GP we are quite interested to see how these compare to them, especially since the 1600 mAh model was able to provide a bit over 1800 mAh capacity at 0.2A constant current load.

We have started the test of the 1.2V AA 1800 mAh GP Rechargeable NiMH batteries with a constant current discharge rate of 0.2A here we’ve managed to get 1829 mAh or a slightly more than the typical rated capacity. This value is just 9 mAh more than what the 1600 mAh model from GP managed to offer at this test, however moving to higher loads the 1800 mAh NiMHs do manage to outperform the 1600 mAh model. So while for lower loads the 1.2V AA 1600 mAh GP Rechargeable NiMH batteries might perform roughly the same, moving to higher loads this 1800 mAh version will be the better choice as they are able to even provide some useable capacity at 2A constant current load.

The performance of the 1.2V AA 1800 mAh GP Rechargeable NiMH Batteries in our tests:

– 1828 mAh at 0.2A load
– 1729 mAh at 0.5A load
– 1270 mAh at 1.0A load
– 103 mAh at 2.0A load

– 2.219 Wh at 0.2A load
– 2.018 Wh at 0.5A load
– 1.352 Wh at 1.0A load
– 0.106 Wh at 2.0A load
