Enermall6.0Ah Replacement for Ryobi 40V Battery Lithium Compatible with Ryobi 40 Volt Battery OP4015 OP4040 OP4026A OP40201 OP4050A OP4015 OP40261 OP4030 OP40401 OP4060

I have used this for a while now in our leaf blower, chain saw and pole trimmer. It holds up about as long as a regular Ryobi battery and has saved me a lot of money. There is no problem charging it and therefore it does everything I could ask for. At this point, I can recommend it.

Lessons Learned. Don't buy upgraded, refurbished or replaced battery products. This battery says it's a 6.0ah but even with a full charge it doesn't put out as much power as my real Ryobi 4.0ah battery. That doesn't bother me as much as the fact that it literally only last about 5 to 10 minutes before it dies completely. My other battery last about 30 to 40 minutes. Not a good product at all for the price.

I bought this to replace an old Ryobi battery that wasn't charging anymore. This thing fits my old Ryobi charger and it seems to bring enhanced life to my leaf blower and lawn mower. Great value!

Works fine, but does not last any longer than the original lower rated battery, even after many years of original battery use. However, slides right in to the charger and my lawn mower and basically does fine as the backup battery.

I have never submitted an Amazon review but with this battery I feel compelled to do so. This battery is NOT 6.0Ah...not even close. It is smaller in size and lighter in weight than the Ryobi 4.0Ah. Unless this manufacturer has invented a new battery technology that no one else knows about, it CANNOT be 6.0Ah. I simply do not understand the 5 star reviews claiming this battery is superior to Ryobi. This manufacturer is guilty of fraud on a par with Donald Trump's real estate appraisals.

Best battery, I would recommend it to anyone.

Not a bad battery for being a Ryobi knockoff, However it's definitely not 6ah. I have an original Ryobi 4ah that lasts just as long as that one. So I would say it's a 4ah. It charges really fast which is a plus compared to the 40v ryobi one. Great price. Not complaining at all. It's just not a 6ah for sure lol

I have had this replacement battery for just over one year. I'm so disappointed with this company. Enermall-US sold me a battery that nevery worked well from the beginning and is now completely dead. Don't purchase anything from a company that makes a product like this... poor craftsmanship, poor quality.
