Update to the note - So far so good. The replacement battery has been working just fine.Bought it in April, went to use it 4 months later and it was completely dead. No lights on the indicator. Charger doesn't even recognize that its connected.Note - After seeing my review, the seller did reach out to me for troubleshooting and ended up sending me a replacement. Hoping for better luck with the new battery.

Recap: I would like to rescind the last submission: You can see below I was not happy with the product and I decided to return it and try it one more time. I received a replacement battery and in true Amazon form, it went very well and the new battery is perfect..I got through my whole yard with NO issues…Thank you to everyone..I bought this for a second battery on the lawnmower and even after charging and recharging to see if the battery memory got better, It didn’t.. I do not recommend this as a replacement. If you have anything that pulls a decent load you might want to go another route….

Replaced dead battery for mower. Worked great after charge - still going strong.

DONT BUY. piece of garbage. Was mowing, and while showing 3 bars, my lawnmower loses power! Spend more and get the batteries designed for the mower you buy. I should’ve known better🤦‍♂️

I use this product for my electric push mower or chainsaw and it does a great job for off brand. Does what a battery needs to do. Been around a year and it still holds pretty good charge.I do have a couple name brand greenworks batteries. This off brand charge doesn't seem to last quite as long but its still pretty good. Its not by a large margin or anything. Thats the only reason I give it four stars. However, I would recommend this one compared to the name brand which is double the price.

Very happy with the purchase,especially since I have a really large yard and now I have plenty of battery to get it all done at once!

So far so good. Fits greenworks leaf blower perfectly. with 6 A-HR capacity I can get around my entire house without a recharge.

Second edit - Yesterday, I mowed the lawn in the coolest temperature since my original bad experience with this battery. I was able to easily complete my back yard with maybe 30% battery life to spare (it's hard to say, as there are only 4 light indicators for battery power remaining). It definitely appears that high temperatures (TN) have a more adverse effect on this battery than they do on the original manufacturer's battery.Edit - While I am still displeased with this battery, here are two points to change my rating from a 1 to a 2 star:1) I used the battery again since my review, and was able to eke out a few more minutes. Perhaps this battery discharges faster when not in use. I got closer to thirty minutes (maybe 28?) this time, which is still unacceptable for a new battery. The outdoor temperature was a little cooler, so that may have contributed to the difference.2) Customer service was quick to reach out to me about the issue. While this doesn't change the performance of the battery, it does make me feel better about the company.I purchased this when it was on sale around Cyber Monday. I was a little nervous about doing so, because I knew I wouldn't be able to do a full mowing until several months had passed. I charged it shortly after receiving it. I installed it, and simply tested it to make sure that it would start my mower (Greenworks 40V 17" - MO40B411). It started fine, so that was somewhat reassuring.I mowed my lawn today for the third time since purchasing this battery. I still have the original battery (the mower+battery were originally purchased in June of 2021), and it works pretty well. I can mow for about 40-45 minutes if the grass isn't overgrown, and that is *almost* enough to finish the job. I purchased this as a backup to be able to easily finish in one session (in other words, to take away the need to charge a battery before finishing the mowing). The original battery hadn't died yet, but I decided to switch over to this newer one (the one that I am reviewing) about halfway through. It only lasted about 20-25 minutes, and I was unable to finish mowing. I would have just put the original one back in, but it had started to rain.To only have gotten 2 satisfactory mowings in while using this battery is unacceptable. The little instruction pamphlet says that it has 300-500 discharge cycles of use. If I can't figure out the warranty situation, then I guess I'll try to time my mowing so that I use this junky battery for the final 15 minutes of mowing.
