7500mAh Extend Capacity Replacement for Ryobi 40V Battery Compatible with Ryobi 40 Volt Lithium Battery OP4026 OP40601 OP4050A OP4040 OP4030 OP4050 Compatible with 40V Cordless Power Tool(Green)

Great product, good value. Easy to install in devices and use. Excellent battery life between charges. Works great.

Probably one of the best replacement batteries. Works great with the blower and the mower. Capacity is higher than original for 4 amps batteries. I doubt it's 7.5 but probably around 6. Still for the price you get a great deal and I recharged it at least 10 times with no problem

I have multiple Ryobi batteries and this one is ok but it lasts about the same, or maybe a bit longer, than a 2AH Ryobi battery. Price is still not bad, if compared to the ryobi battery. Also the latch button is a little harder to release. it charges fine in the Ryobe chargers I have. Time will tell how many charges it will take.

I retrack this review - could have been an issue with the device not the battery but not certain Fully charged overnight and all lights were green but when I put in Ryobi blower all I got was a grunt sound and no power. Old battery still worked so not the blower. Returned for full refund.

Great value

Worked fine for about 5 charges, then stopped taking a charge.

May be too new to rate, but I just recently bought a Ryobi 40v blower, 12" chain saw, pole saw and a weed eater with the expand it brush cutter. I bought a Forester carbide tooth blade to help me take down a lot of bamboo. The stock 4 amp battery I had to feather the speed to let it get going before hammering "full throttle" or the overload circuits would shut down the blade. With this 7.5 amp blade, I can hammer full throttle right away. Thank goodness now I can start knocking out that cane!

I don't know what the negative reviews are about. I got it, charged it, started using it, and worked perfectly fine. Battery lasts a good length of time, and fits my drill just fine. Good battery, good price.

Good lasting battery.

it worked and was affordable.

Came in time. As described. Charged it. Holds and keeps a great charge. Use it for my cordless black and decker drill. Glad I could still find one for my B&D. Not the sellers fault. But the replacement battery almost cost as much as the drill. Lol. But still happy with my purchase.

I installed the battery & I have checked it each day for a week & it maintains it's charge.

Same as above.
