Futurebatt [2-Pack] 18V High-Output 6.0Ah! Lithium Battery for Ridgid 18V Tools Battery R840089 R840087 R840086 R840085 R840084 R840083 AC840085 AC840086 AC840087P 18 Volt Battery

Been good. Works like it should.

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!

Was pleasantly surprised at performance and build quality. I would buy these again. I have had no issues after a month and I have beaten these batteries up

I was having difficulty locating a battery for an older hand drill I hadn't used in ten years or longer. After months of researching batteries I decided on this generic battery. It arrived fully charged and ready for use, my twenty year old Black and Decker was humming like a new drill. I seldom throw any tools away regardless of the condition or age, and this example may be why. I have gone to yard sales and bought old wrenches/spanners that someone used too much torque and broke one end of the open-end wrench. I always ask "how much do you want for this old broken wrench?" Surprisingly I have walked away with a free wrench more times than I can remember. A hundred percent of the time, the other end is completely functional.

They work just fine.
