Using a Uniross intelligent charger, four of these showed a (perfectly acceptable) capacity of 2.5+ Ah on their initial test. although one took considerably longer toi charge than the other three. I have others of this type and the big capacity is useful, e.g. my wireless doorbell needs charging only every 4 to 5 months They seem destined to have a long working life..Excellent value!

It's always a bit of a guess getting off brand batteries. My experience is that if you want/need good ones, then go for the brand names like Eneloops and pay more. These chinese ones are no exception. My capacity testing of 4 of these came out with results 1590-1740mAh. That's discharge to 0.9v using a diy'ed test board with HW-586 pcb's so I wouldn't claim this is definitive, but the pcb's have proven to give good ballpark results with lots of cells. SO: capacity is not 2800mAH (not too surprised), more like1900mAh max;. Only time and usage will tell the full story, they look pretty decent, but stated capacity should be more accurate.

I bought these for my Canon Digital Camera. I have had 6 Duracell rechargeable AA batts. for a few years, which have been charge & reused numerous times. They are now beginning to reduce in efficiency. I bought these expecting to get new batteries that charge quickly & last a good while in the camera, similar to the Duracell ones. No such luck. They charge up all right, but then they discharge very quickly. Sometimes I put them in the camera after recharge, take a photo & switch off the camera. When I return to the camera a day or 2 later, the batteries have no charge left & need changing. Put in the other 2 batts, charged at the same time, NO LIFE at all. The only good thing about these batteries is the handy plastic case they came in !!!

To early to tell if these batteries are as good as the market leaders, but so far so good. Dont know if the 2900 Mah can be trusted yet, but it seems preety good at holding it's charge so far.

I have used this brand before and have found them to be of better quality (holding charge and maintaining capacity and not giving up the ghost after only a few cycles) than many brands. Only negative is that these are rated 2900 mAh with a minimum 2700 mAh, but actually only achieve 2500 mAh at best when tested.
