These are not 6.6 Ah as described. One of these batteries fully charged does not last as long as the 4Ah Ryobi batteries that came with my tools. As the Ah rating of theses batteries is over 1-1/2 times, I would expect that the battery would also last about 1-1/2 times, which they do not. I would strongly recommend that you pass on these batteries.

Updated review October 4, 2004: I got this at the beginning of May and have used it all summer. It charges quickly and allows me to finish my whole front yard without having to change batteries, just as the original Ryobi battery used to. I'm still very pleased with this purchase! I got this replacement battery for my Ryobi lawnmower. The original battery died, and Ryobi didn't offer an affordable option. I have used it 5-6 times, and it's working great so far. I've had no issues charging it. I can now mow my whole yard again on one battery without it dying out. It takes 30-40 minutes, depending on the grass height. I am very happy with the quality of this battery. If anything changes, I will update my review.

While they work and a single battery lasts long enough to trim my yard, by the size alone they aren't 6.6. Most likely just a 4.0 is comparing case sizes to the original OEM batteries. My only other gripe is the latch is a little snug, so the battery really has to be slammed into position to catch. For the price I'll keep them, but buyer beware.
