Whoever wrote the review praising the virtue of these batteries must work for Ryobi marketing. I have owned several of these batteries as I have many 18V R tools which I used to run on NiCads. I could go on how bad their Nicads are but they are cheap as are their tools, which keeps me in their game. I am a carpenter that uses these tools all day. Anyhow these Lithium batts are unpredictable. Most times hold a charge and sometimes not. Sometimes they won't even charge. I have also gone through 4 chargers. The fuses pop.The fuse is an odd size and if you try and replace it yourself be carefull of the fireworks when you plug it in. The batteries have a one year warranty so then you find yourself spending all thiss time finding an authourized service dealer to exercise the warranty. (Retailers won't handle it). You will also have to bring in your charger and a tool to test all 3 items. Part of the warranty requirements. One day I'll smarten up and bite the bullet and dump all these Ryobi tools. The service repair guy told me ALL Lithium batteries by almost all manufacturers are lousy. He said the technology is in it's early stages and far too buggy. Better to stay with the Nicads for a while longer.
