Let me tell you, this CELL9102 battery has been a game-changer for my Ryobi tools. I was skeptical at first about using a non-OEM battery, but after putting it through its paces, I'm thoroughly impressed.

The 3.0Ah capacity means I can work longer without constantly swapping batteries. Last weekend, I used it with my drill while building a deck, and it outlasted me - and I'm not exactly known for taking breaks!

What really surprised me was how well the protection circuit works. The other day I accidentally left it in the charger overnight (we've all done it), and it didn't get hot or show any signs of overcharging. That smart protection gives me peace of mind.

Performance-wise? Honestly, if you handed me this and an OEM battery with the labels covered, I wouldn't be able to tell the difference. It powers my circular saw just as strong as the original ever did.

The only minor gripe? The fit is slightly tighter than OEM when inserting into tools - not a problem once it's in, but you notice it during insertion. Small price to pay for the savings though!
