One thing we found with these, the new lithium plus ones won't show the 20v or so when you check them with a multmeter after they are charged. But instead something less like 7-8 v. Don't fret. They really are fully charged to 20v. The new ones have a priotective circuit built into them that won't show the full 20v or make it available unless there is a load on the battery. As soon as you pull the trigger on the tool, it gets the full 20v. You just can't check them the way you used to on previous Ryobi batteries. This alarmed quite a few of us months back at black friday when many of us bought these lithium plus in the 2 for $99 deal. They are very good batteries - Paul
