Input: The title says it all. I was expecting to get a good bit extra work time with my Ryobi string trimmer since this battery is rated 50% more capacity. Not, so, it's essentially the same capacity as the 4 Ah Ryobi battery. Advertising is inconsistent with reality.

Rated much higher capacity than the Ryobi battery it replaces, but is about the same.
