The 8.4V 280 mAh Fujicell NiMH batteries we are testing here are from the traditional type of rechargeable Nickel Metal Hydride batteries and they come with a pretty high capacity for their type of 280 mAh, so we would be interested to see if they can actually deliver it. Fujicell rates these batteries as being capable of being recharged up to 1000 times, so they should be able to serve you for pretty long time considering that this type of batteries is often used for low power applications.

In order to test the capacity of the 8.4V 280 mAh Fujicell NiMH batteries we are using a constant current discharge rate of 0.05A (50 miliampers) and we have managed to get 285 mAh capacity before hitting the 7V cutoff voltage and that is actually a bit over manufacturer’s rating for this battery that is 280 mAh. So we cans ay that with this battery Fujicell has done a good job and they manage to deliver what they have promised as capacity, now if only the battery was also a low self discharge type NiMH, but nevertheless a good product from Fujicell.

The performance of the 8.4V 280 mAh Fujicell NiMH Batteries in our tests:

– 285 mAh at 0.05A load

– 2.486 Wh at 0.05A 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.

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
