Works like it should. Review: I bought this 2-pack of Futurebatt 18V 6.0Ah batteries hoping to get some affordable replacements for my Ridgid power tools, as the originals were getting old. At first glance, they seemed like a good deal—high capacity promised longer runtime, and the price was half of what OEM batteries cost. Unfortunately, these turned out to be a complete waste of money. Right off the bat, one of the batteries wouldn't hold a charge properly. After fully charging it (which took forever, by the way), it died after just 10-15 minutes of use on my drill, even on light tasks. The second one fared a bit better initially, giving maybe 20-25 minutes, but that's nowhere near the "high-output" 6.0Ah they claim—my old 4.0Ah Ridgid batteries last longer! Over the next couple of weeks, both started overheating during use, causing my tools to shut down prematurely. I've tried them on multiple tools (drill, impact driver, and saw), and the results are consistent: poor power delivery, frequent cutouts, and rapid drain. Compatibility is another issue—they fit into the tools, but the connection feels loose, and I've had them pop out mid-job a few times. Plus, after about a month of light use (maybe 5-6 charges each), one battery stopped charging altogether, showing error lights on the charger. The other is barely limping along. For something advertised as "high-output," this is laughable. Save your money and stick with genuine Ryobi batteries or a more reputable third-party brand. These Futurebatt ones are cheap for a reason—they're junk. Total regret; I'm out my money and back to square one. Do not recommend! ## Features - 【Large Capacity, Full Compatible】6.0Ah High Capacity professional lithium battery for Ridgid 18V lithium battery R840087, R840083, R840085, R840086, AC840089, AC840085, AC840086, AC840087P Series - 【Works with original charger】Works with original charger: fit RIDGID 18V Lithium system of cordless drill tools, works with Ridgid 18-Volt lithium battery charger R86092 - 【Fade-free Power, Quality Cells】Fade-free Power/Capacity: over 500 cycle times, high capacity 6.0Ah lithium battery 18V, long lasting/ more run-time and powerful in working - 【Convenient to Use Design】With on-board fuel gauge, integrated LED battery charge level indicator allows user to monitor battery using.
