Test/Review of Fujitsu Premium AA

[size=+3]Fujitsu Premium AA[/size]

Official specifications:

Nomimal voltage: 1.5V

It looks like Fujitsu has changed names on their different battery series. This is supposed to be the super battery for all types of devices.

There is a significant capacity jump between 0.2A and 0.5A, either I got a bad battery or it is best to only use this cell for devices with 0.2A or lower drain.

The battery is fairly good, if it is kept out of the most power hungry devices.

How is the test done and how to read the charts
Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

Thanks a lot for your excellent review as always. HKJ! :thumbsup:

This is a premium battery at lower current, but not at little higher current.

I always thought an AA Alkaline capacity was around 2800mah maybe 100ma drain is too high, maybe try 50ma if your test equipment and time allows.

I do test some alkaline at 10mA, but it is rather slow.
Here is one:

Down to 1 volt it has about 2600mAh

Well, there are some Alkalines which can deliver up to 3000 mAh, but only under a very light load (such as a wall clock). Capacity drops significantly with current (much more so than with rechargeables). At 100 mAh you will get around 2.5 Ah, at 200 mAh around 2.2 Ah, and at 500 mAh around 1.6 Ah. At 1000 mAh this drops to 1.25 Ah, so far less than half the capacity is useful there. Rechargeables are much more stable with their capacity under higher loads.

Whoops, it took several replies for me to realize that this is about an alkaline cell. :duh2:
No wonder it has unimpressive performance.
