I've been amassing Ryobi 18V tools for several years- started with the blue tools that came with NiCad batteries (these batteries are all pretty much gone, but they're going on 10+ years). The newer lime-green tools have the Li-ion batteries- my current ones are probably 3-4 years old and seem to be holding up well. They also seem to hold a charge longer than the old NiCad ones. Smaller form-factor, too. As others have stated, the batteries are compatible with the older tools.Mine are all Bosch or DeWalt. IIRC Rigid is same as Ryobi but not entirely sure. If I was right now starting from scratch and did not need really powerful or "pro" level tools for some things I do I would likely go that same route with Rigid or Ryobi for the lifetime batteries. But they don't make anything in the 3/8" and 1/2" drive impact or 20V grease gun. So it's why I have the ones I do. My battery powered impact wrenches (Bosch 1/2" and DeWalt 1/2"and 3/8") are more powerful than my air powered SnapOn 3/8" and my CP734H air powered impacts. So now all I need is a battery powered ratchet or 2 and I am all set. I will hardly ever again need my big air compressorII
However, Ryobi only has a three-year warranty on their batteries (and tools).
