1.2V AAA 1000 mAh Xcell NiMH Battery Tests

The 1.2V AAA 1000 mAh Xcell NiMH batteries are standard non low self discharge NiMHs and although rated with some of the highest capacities for AAA NiMHs we have our doubts that they will be able to provide 1000 mAh. We’ve already seen that Xcell’s AA NiMH batteries are rated higher than what they actually can provide, so we are expecting to see similar results here with the AAA NiMH batteries from Xcell.

We have started the test of the 1.2V AAA 1000 mAh Xcell NiMH batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 859 mAh as capacity, or quite a bit below their rated 1000 mAh capacity. We can’t say we did not expect to see something like that, though looking at the performance of these Xcell AAA NiMH batteries with increased constant current load they do manage to perform good. So if they were rated at 850 mAh instead of 1000 mAh they would’ve not only meet their rating, but also perform great for 850 mAh rating. In the end if you want higher capacity 1000 mAh AAA NiMH batteries then you better look at some other products that are actually able to deliver.

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

– 859 mAh at 0.1A load
– 767 mAh at 0.2A load
– 707 mAh at 0.5A load
– 654 mAh at 1.0A load

– 1.070 Wh at 0.1A load
– 0.941 Wh at 0.2A load
– 0.841 Wh at 0.5A load
– 0.736 Wh at 1.0A load

1.2V AAA 1000 mAh Sanyo Superlattice Alloy Evo NiMH Battery Tests

The 1.2V AAA 1000 mAh Sanyo Superlattice Alloy Evo NiMH batteries are the standard Sanyo batteries that are not low self discharge (LSD) like their Eneloop series, but as we’ve seen other batteries from the same “regular” series performing great as one would expect from Sanyo. These batteries are rated as 1000 mAh typical capacity and have a rating of 930 mAh minimum capacity and we did expect to see them managing to meet these specifications. Of course we do plan to test the Eneloop and Eneloop XX LSD NiMH batteries very soon as well, so stay tuned form more battery tests of products coming from Sanyo.

We have started the test of the 1.2V AAA 1000 mAh Sanyo Superlattice Alloy Evo NiMH batteries as we normally do with a low constant current discharge rate of 0.1A and the result we got was 1050 mAh as capacity and that is pretty impressive. At 0.2A they manage get close to 1000 mAh, even at 0.5A constant current load these batteries manage to provide more than their minimum rating and going even higher at 1.0A they still manage to perform very well. In the end as we’ve expected from Sanyo these regular series coming from the company manages to perform really well and exceed their specifications, so really a great product.

The performance of the 1.2V AAA 1000 mAh Sanyo Superlattice Alloy Evo NiMH batteries in our tests:

– 1050 mAh at 0.1A load
– 972 mAh at 0.2A load
– 934 mAh at 0.5A load
– 838 mAh at 1.0A load

– 1.335 Wh at 0.1A load
– 1.211 Wh at 0.2A load
– 1.129 Wh at 0.5A load
– 0.963 Wh at 1.0A load

1.2V AA 2800 mAh Fujicell NiMH Battery Tests

The 1.2V AA 2800 mAh Fujicell NiMH batteries we test here are of the standard NiMH type and are rated pretty high at 2800 mAh (the company also makes LSD NiMH batteries that we are soon also going to test), so we were quite interested to see how these perform, especially considering that they are available at a good price. Now, before moving on to the tests we should clear something important, as some people associate the brand Fujicell with Fujifilm (Fuji), even though both companies have nothing to do with each other. Fujicell is not associated with Fujifilm, although both companies are Japanese and apparently are taking advantage of the popular Japanese Mount Fuji.


1-2v-aa-2800-mah-fujicell-nimh-battery-capacity

We have started the test of the 1.2V AA 2800 mAh Fujicell NiMH batteries as we normally do with a low constant current discharge rate of 0.2A and the result we got was 2532 mAh as capacity and while this is a bit shorter from the 2800 mAh rating it is still quite good performance for not a very popular and well known brand of batteries. Increasing the constant current load going all the way up to 2.0A we still manage to get very decent performance, meaning that they can handle well both high and low load applications. If Fujicell has provided a minimum guaranteed capacity rating of 2500 mAh for these batteries they would’ve met their specs, but now we can say that they fall short of the 2800 mAh rating by quite a bit and even the faster self discharge of higher capacity batteries is not a reason enough for such a difference.

The performance of the 1.2V AA 2800 mAh Fujicell NiMH batteries in our tests:

– 2532 mAh at 0.2A load
– 2384 mAh at 0.5A load
– 2263 mAh at 1.0A load
– 1804 mAh at 2.0A load

– 3.115 Wh at 0.2A load
– 2.881 Wh at 0.5A load
– 2.620 Wh at 1.0A load
– 1.925 Wh at 2.0A load
