Replacement for Ryobi 40V Battery 6.0Ah Compatible with Ryobi 40 Volt Battery OP4040 OP40401 OP4026 OP40261 OP4050 OP40201 OP40601 Compatible with Ryobi Battery 40V Cordless Power Tools 2-Pack

Really like these batteries. Not only are they lighter, they also let you know how much juice is left by pressing the battery test button. Nice feature. The price is great too. Highly recommend these batteries for your Ryobi!!

These batteries work perfectly in my Ryobi tools and cost a whole lot less than the Ryobi brand name batteries. They also have a battery level meter on the front so you know how much power you have left. Just push the button.

Fit perfectly in the charger and the tools. Held a charge as well. So made it handy not to keep charging. I left it for three weeks in my drill and the nex time I used it still was fully charged

Absolute Must buy. Value can not be beat. Battery is same quality that you will pay double for at Stores. Battery Life is the same as original Ryobi battery that came with purchase. I purchased these as backup extras

The batteries charge fast and run longer than the original batteries. Plus they have a lights on the side that shoe how much power is left. They are worth the money. Extremely pleased!

I bought these instead the OEM version. So far as good. Like the built in tester, it shows how much juice left.

These are great replacement batteries. They seem to be holding a charge just as good, if not better than the originals.

Works as expected
