I've had several four-packs of these for a year or so and those are standing up to intensive use quite well, so I bought some more of the same. Initially the first sets did not seem to have the full capacity, but following the first few charge-discharge cycles they have remained stable on specification.

All the cells I have (now 12 four-packs bought at different times) measure within the specification of a standard AA cell for the body (14.5mm x 50.5mm), but the positive terminal on this series does not stick out quite as far as that on a Duracell (only by about half a millimetre) and does not make contact in a few items that have a slightly deeper recess for it.

I had previously bought some Maplin's 2500mAH cells at the same time as an ATC Dr.Charge charger. The Maplin's cells sometimes did not quite last a 12 hour shift, but these Extremes seem to have a couple of hours in hand for a useful safety margin.

As is normal for NiMH rechargeable cells these are not so good as the Alkaline primary cells when very cold, and the NiMH type definitely needs to be kept above freezing to work at their best. Full function is restored when they warm up again. For the best end capacity, allow them to reach a comfortable room temperature before re-charging. See the Wiki for more info in the articles on both sizing and charging characteristics.

I use these rechargeable batteries in my digital camera.....longer life than most others I have had, seem to go on for ever, gave a set to my sister and she is very impressed with the way they hold their charge, also in a digital camera. When they no longer charge I won't hesitate to get more, but it could be quite some time yet...

The batteries perform perfectly well but do not live up to the described battery capacity.
When charged with a charger that records capacity (Powerex M-C9000),the best they offer are 2650 mAh, and some only offer 2350 mAh. So do bear this in mind when purchasing.

Got these batteries in the hope that they would have sufficient juice to power the Braun Pedi. And they do! I had tried other rechargeables and they just weren't up to it, but these are.

As a wedding photographer it is important that I use batteries which hold their charge well to save time and hassle during the day. These do just the job, I have recharged them multiple times and I have not noticed any change in their capacity. I would highly recommend these batteries

This was a really good price, and excellent fast delivery (post free) - I will use this supplier again - excellent. As an aero-modeler needing power supply for servos and radio gear these cells are excellent - high performance, and at a very good price.

One big drawback to these batteries is that they are larger in diameter than ordinary AA batteries so they are too large for a lot of items!

Brilliant. So much tougher than the Annsmann ones I bought first, therse hold their charge very well, are less prone to fade and as yet have not failed.

Good quality batteries - so glad I've switched to rechargeable batteries for my photography equipment as it's much cheaper and more convenient.
