2Pack 40v 8.0Ah OP4026A Replacement for Ryobi 40V Battery Compatible with Ryobi 40 Volt Battery Lithium OP4015 OP4040 OP40201 OP4050A OP4015 OP40261 OP4030 OP40401 OP4060 Power Tools

One of the batteries works, one won't charge. The batteries came charged. After using them, one of them charges normally, the other fails within a minute or two on the charger (the charger changes to flashing red). Because this is sold through a third party, I can't directly return the item. I've now attempted to contact the seller twice (hopefully the second one will have gone through), but I can't even find the messages I've sent on Walmart's website. Buy at your own risk.

Delivery was faster than originally predicted. The batteries were tried in the lawnmower and worked right away. They went on the charger okay. I expect they'll be quite satisfactory.

Part doesn't fit. Have tried returning for over a month. Have tried contacting them and no response. Stay away from this business. SHADY.

I ordered 4 batteries. Two batteries would not charge and the charger place them in error mode. I notified the seller, and they were immediately replaces with working unit. Great seller support. Good batteries too. They last a lot longer than my 4 AMP batteries.

Well worth the money! I replaced a single 6.0 Ah that only lasted 2 years with these two 8.0 Ah batteries at a significantly cheaper price. I was initially hesitant to purchase because they were aftermarket and was worried I'd have loss of power or bogging down, but they are just as good as the original Ryobi batteries with way longer run time. I've had them 6 months now and have seen no issues. Even if they only lasted a year, I could make another purchase and still be significantly under the price of 1 Ryobi battery; but again they show no sign that they won't last.

very good and heavy. love them

I never received the product. Am still waiting for the refund 11 days later..

Very good battery, better than the original battery, has built in protections. Great value.

Bought these for my Ryobi self-propelled lawn mower. Fit fine in my charger %26 mower %26 longer run time than original battery. Excellent product!!!

I have used them most of the summer, and they have worked pretty well. Wet grass, higher then normal, using the self propel feature all the time all drain the battery faster. Oh, self propel use up hill also uses up power faster.
