8-4v-280-mah-fujicell-nimh-battery

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-aaa-1000-mah-varta-power-accu-nimh-battery

The 1.2V AAA 1000 mAh Varta Power Accu NiMH batteries are of the highest capacity rechargeable AAA size NiMHs that Varta offers, though these are the last of the non-LSD models as the company has apparently decided to replace this model with a low self discharge version. So far we’ve seen very good results in terms of performance from Varta batteries (especially when used in low power applications), so here we also have high expectations.

Starting the test of the 1.2V AAA 1000 mAh Varta Power Accu NiMH batteries with a low constant current discharge rate of 0.1A and got us 1086 mAh as useable capacity and that is a great result making these batteries great for use in low power applications. In fact the 1086 mAh capacity is the highest capacity from a rechargeable AAA size battery that we’ve measured so far. By further increasing the levels of load we still get good levels of capacity, though the results here are not as good as the one with 0.1A and they are more moderate, but still showing that these Varta batteries can handle pretty good high power use as well.

The performance of the 1.2V AAA 1000 mAh Varta Power Accu NiMH batteries in our tests:

– 1086 mAh at 0.1A load
– 818 mAh at 0.2A load
– 757 mAh at 0.5A load
– 742 mAh at 1.0A load

– 1.345 Wh at 0.1A load
– 1.013 Wh at 0.2A load
– 0.890 Wh at 0.5A load
– 0.799 Wh at 1.0A load

1-2v-aaa-1000-mah-gp-nimh-battery

The 1.2V AAA 1000 mAh GP NiMH batteries we test here are of the standard NiMH type and are rated at 1000 mAh typical capacity and 930 mAh minimum guaranteed. Our experience so far with GP batteries has shown that some models are performing great while others not so well, so it will be interesting to see to which group we can add these batteries. So time to start the testes…


1-2v-aaa-1000-mah-gp-nimh-battery-capacity

As we usually do we have started the test of the 1.2V AAA 1000 mAh GP NiMH batteries with a low constant current discharge rate of 0.1A and the result we got was 1085 mAh and that is pretty impressive for a battery rated at 1000 mAh. Going further with a load of 0.2A and we managed to get 1005 mAh which is still over the typical rating of these batteries, and with even higher load we still manage to get good results, though not that impressive as at 0.5A we are are a below the minimum rating. Still we are seeing very good performance from the 1.2V AAA 1000 mAh GP NiMH batteries.

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

– 1085 mAh at 0.1A load
– 1005 mAh at 0.2A load
– 876 mAh at 0.5A load
– 796 mAh at 1.0A load

– 1.325 Wh at 0.1A load
– 1.211 Wh at 0.2A load
– 1.029 Wh at 0.5A load
– 0.874 Wh at 1.0A load
