40V 6000mAh Lithium Replacement for Ryobi 40 Volt Battery 6.0Ah Compatible with Ryobi 40V Battery OP4040 OP40401 OP4026 OP40261 OP4050 OP40201 OP40601 Compatible with 40V Cordless Tools (Green)

Waited to use these batteries a couple of months. Dare I say better than the original. Yes, so far. Longer lasting with no problems at all. Let's see if they last long too

This battery works well in my Craftsman drill. It’s great to have an extra when you have a lot to do.

Good batteries for a great value, only giving 4 stars for what appears to be misleading advertising. These are fully functional 40v batteries that do work with the Ryobi platform, but these appear to be carbon copies of the 4ah batteries not the 6ah. These only last around 15 mins each in the 40v mower as opposed to the 30+ of a real Ryobi 6ah. See the image for what I'm talking about. The two center batteries are what I ordered here. 6ah Ryobi on the right, 4ah Ryobi on the left.Still a solid deal, just not a true 6ah pack.

The demise of Sears meant the end for my battery powered Craftsman tools - no replacement batteries -UNTIL I FOUND these! They work perfectly and saved me big bucks that I would have spent for replacement tools!

Been looking out here at the usual stores that you would buy these replacement batteries for and the prices are outrageous. I honestly saved myself $60-$100 just purchasing this from Amazon. I was able to slap this thing right into my drill and it instantly turned on I know it says that you’re supposed to charge it, but I wanted to see if it at least functions and was the proper fit l. And I am satisfied and I’m looking to purchase a second .

Liked the price. Purchased the drill + 2 batteries years ago. When I battery failed to maintain a charge, then eventually failed to charge at all, I went to Sears & was quoted a price for the battery higher than the price paid for the drill.

I was afraid that I would have to give up my beloved Craftsman drill after both batteries I had for it malfunctioned. Enter this battery! It works with my old charter and will allow this drill to continue to serve me for many years to come.

Maybe you'll have better luck than I did but use caution with this item. They appear to be like the Ryobi 40v OEM but I noticed they were very stiff to insert. I compared them to OEM batteries and their sizes are slightly off. I have 7 different tools, and I could only connect them to two (one being a blower). While they work if they fit, the power output is noticeably less than the originals. My blower has a regular and turbo mode. The turbo with this battery was the same or less than regular on the OEM. I have a triple charger and the charger refuses to charge these batteries, erroring out. Warning: There are a lot of 5 star reviews to give it a high average, but if you look, they're all for a totally different battery (Craftsman drill).
