Last long enough for a good hour worth of use .

Had to replace my Ryobi batteries. I was down to one that would not hold a charge for long. Factory batteries are expensive so looked into after market. There are a lot of negative reviews on after market batteries but decided to take a chance on these since the price was low. They came fully charged and the one I have been using is still reading fully charged a month after getting it. I have only used it lightly so far. I feel like they don't give the same torque as the factory batteries but I have not tested that yet.

These batteries work perfectly on my Ryobi power tools, and cost considerably less than the name brand ones

These batteries are very short on life after being charged. The battery supplied by the original tool seemed to last through the workday. As for these batteries, they pretty much go flat after one hour or less.

Worked in the devices. Will see after multiple charges if they are quality.

Works fine in the tools, but does not work well with the charger. Charger consistantly shows that it's a bad battery. Had to unplug and replug numerous time to get them to full charge. Unfortunately I missed the return window and am now stuck with 2 useless batteries.

I acquired these as quite frankly, I can never have enough batteries for my many Ryobi tools. They arrived with the a charge indicators fully illuminated, so I did not charge them further. They are physically the same size as my OEM 4ah batteries. I used my most power hungry device, a leaf blower and it seemed to actually blow harder. Not it could be that my 4ah batteries are getting a little long in the tooth, but these ran longer. Now, I know your thinking that of course they do, they are 6ah, but I rarely trust those ratings. It has been my habit to reduce them to the next common ratings. So a non OEM 4ah is a 2-2.5ah, a 6ah is a 4ah, etc as that had been my findings. These might very well be as rated. Regardless, the value is clear. These are a fantastic deal (57.59 2 pack, at time of review).

So far,so good
