One of the biggest signs that rechargeable batteries will last the longest amount of time is the mAh capacity rating. At 2,850mAh, the Annsmann Digital batteries are the highest-capacity rechargeable cells that we have ever seen.
Of course, it’s not the figure printed on the battery that is important, but the capacity that can be delivered. In our rapid-drain tests, we measured our Annsmann Digital sample batteries with a final capacity of 2,728mAh. This is 96 per cent of the rated capacity, but still puts makes these batteries the highest-capacity models that we have reviewed.
As you’d anticipate from such high-capacity models, they are not low self-discharge models, so they will lose charge faster than models that use this technology. As such, you will ideally need to charge these batteries close to the time that you require them. Fortunately, they also support fast charging, so you can get them charged quickly as and when you need them.
With the highest capacity we have ever tested on AA batteries, plus a decent price for a pack of four, the Annsmann Digital 2,850mAh cells are a great choice for high-drain devices, such as digital cameras. However, if you can make do with slightly less capacity, the Duracell Rechargeable Supreme are much better value and their tested capacity was only slightly less.
