6.0Ah Replacement for Ryobi 40V Lithium Battery OP4026 OP40601 OP4026A OP40261 OP40201 Cordless Power Tools

Had an old Ryobi drill and needed to go to new technology batteries. This has perfect fit, and the battery seems very good. Haven't had to even use the second battery yet - still on the first charge of the first battery, after a few small jobs over a few months of use.Only gripe - even though the charger is almost the same size as the original one, it won't fit into the place for the charger in the original Ryobi drill case. Not a big deal, just makes it a bit more to carry around. Would purchase again.

I have Ryobi tools for many years. The old batteries needed to be replaced very often. It is almost better to buy new tools with new battery packs. This replacement batteries is cheaper and also last at least 3 times as long. I am very happy with this purchase.

On first use after a full charge it only lasted 15 minutes. The return window is expired so I feel ripped off. Do not buy.

I had ruined a battery in the rain while out of town, now I can knock the growth back with my new power.

Great replacement

the following are two major issues with the battery I received:1--The battery arrived Partially Charged, the Ryobi charger did not charge this battery it flashed green/red indicating defective battery.2--The battery did not fit my Ryobi trimmer. It was very hard to get the battery on the trimmer, even harder to get it out.Maybe my battery bypassed quality control, but in either case It was returned for a full credit.

Battery life not nearly as long as it should be for a 6.0

Recharged it twice, now it is dead. Buy the Ryobi. It's more expensive, but at least it works.
