1.2V AA 2700 mAh Sanyo Superlattice Alloy EVO NiMH Battery Tests

20 Aug


The 1.2V AA 2700 mAh Sanyo Superlattice Alloy EVO NiMH batteries (model HR-3U) we test here are from the traditional NiMH type and not the newer Low Self Discharge (LSD) NiMHs even though Sanyo is also making LSD batteries and is considered as one of the top names for Rechargeable batteries. The NiMH batteries from Sanyo we are testing here are rated as 2700 mAh (that is the typical capacity and 2500 mAh minimum) and that is one of the highest capacity NiMH batteries on the market currently available. What we are expecting from these Sanyo NiMH batteries is to actually provide the said capacity and not behave like some unknown brands making batteries that are marked with very high capacities of over 3000 mAh, but hardly capable of delivering even half of that capacity. What is the most interesting thing here for these Sanyo NiMH batteries, besides their high capacity, is that they are rated as capable of handing very high loads such as 2C (two times their capacity or 5.4A) while till providing very good capacity.


We started the tests of the 1.2V AA 2700 mAh Sanyo Superlattice Alloy EVO NiMH batteries with a constant current discharge rate of 0.2A and they were able to provide us with 2527 mAh or a bit over the minimum rated capacity, and at a lower discharge rate they should be able to get closer to 2700 mAh. The important thing here is that Sanyo has a proper rating for these batteries, nothing less than what we have expected from them anyway. Furthermore these batteries are able to handle high current loads very well as you can see even at 2A constant current load they provide close to 1900 mAh capacity. So in overall the 1.2V AA 2700 mAh Sanyo Superlattice Alloy EVO NiMH are very good rechargeable batteries that are suitable equally well for use in applications requiring either low or high current load. They however excel at providing great capacity with very high loads.

The performance of the 1.2V AA 2700 mAh Sanyo NiMH Batteries in our tests:

– 2527 mAh at 0.2A load
– 2498 mAh at 0.5A load
– 2338 mAh at 1.0A load
– 1868 mAh at 2.0A load

– 3.141 Wh at 0.2A load
– 3.002 Wh at 0.5A load
– 2.664 Wh at 1.0A load
– 1.949 Wh at 2.0A load
