Ryobi P118 Lithium Ion Dual Chemistry Battery Charger for One+ 18V Batteries (Battery Not Included) - Fast Charging for Power Tools, Drills & Outdoor Equipment

Great Charger for both Charges my Ni-Cd and my Lithium 18V Batteries. I had 3 batteries that I purchased with my Ryobi tools so that I would never run out or power, but that was over 3 years ago. When they took longer and longer to charge and finally would not charge at all, I just figured they had gone bad. I found a really good deal on Lithium Batteries (not here) so I got 2 of them for what Amazon was charging for one and figured that would solve the problem, WRONG. it turned out the be the charger. I ordered this charger and now have 5 fully charged batteries.This charger worked great with the Lithium and did the job on each of them in about 30 minutes. Now they came with a little charge from the factory, so I don't know how long it would take to charge a fully depleted Lithium, but it was very fast on the new ones for initial charge.Nicads took about 2 hours each BUT I know they were FULLY depleted. MY Drill would nto turn at all with any of the batteries, nothing. When I first put the batteries - each reacted the same- it took about 30 to 60 seconds for the charger to turn from solid red to blinking green and indicate it was charging. Two hours later or so the charge was complete.I highly recommend this charger for Ryobi Batteries.
