The 1.2V AAA 850 mAh Hama Ready for Power NiMH batteries are rechargeable batteries of the LSD type (Low Self Discharge) – batteries that come pre-charged and ready to be used and that retain most of their capacity over longer periods of time unlike the standard NiMH batteries that lose their charge at a faster rate. Hama is an European brand that is known for various computer and not only computer accessories and they often have interesting products at good prices, so let us see if these batteries are such a product or not…

We have started the test of the 1.2V AAA 850 mAh Hama Ready for Power NiMH batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 992 mAh, a surprisingly good result from a battery rated at 850 mAh. Increasing the constant current load to 0.2A these batteries still manage to provide more than their rated capacity, and going for 0.5A load they fall just a bit below their rated capacity. Even with a 1.0A constant current discharge load we got surprisingly high useable capacity, meaning that Hama did really well with this product and it not only meets the ratings, but surpasses them quite a lot. The batteries handle very well not only with a low current load, but with a high loads as well, making them suitable for all applications. the good useable capacity under low and high loads, together with the low self discharge capabilities makes these rechargeable Hama batteries a good choice for various needs.

The performance of the 1.2V AAA 850 mAh Hama Ready for Power NiMH Batteries in our tests:

– 992 mAh at 0.1A load
– 897 mAh at 0.2A load
– 843 mAh at 0.5A load
– 766 mAh at 1.0A load

– 1.239 Wh at 0.1A load
– 1.103 Wh at 0.2A load
– 1.000 Wh at 0.5A load
– 0.852 Wh at 1.0A load
