Okay, so I've been using this CELL9102 battery for my Ryobi One+ tools for about a month now, and here's the real tea...

First off - the price difference vs OEM is insane. Like why would I pay double when this works just as well? The 3.0Ah capacity gives me solid runtime for my drill and circular saw. Did a whole deck project without constant battery anxiety.

The protection features actually give me peace of mind. Had one incident where I left it charging overnight (oops) but no overheating or swelling like some cheap knockoffs.

Performance-wise? Literally can't tell the difference from my original Ryobi battery. Same power output, same compatibility with all my One+ tools. The only minor thing - the plastic casing feels slightly less premium, but who cares when it works perfectly?

For anyone skeptical about third-party batteries: This one's legit. Saved me enough money to buy another tool with the difference!
