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….

Easy to charge the battery. The charge will last approximately thirty minutes. So it definitely pays to have two batteries.

I bought pack of 2 40V, 6AH mower batteries. Great price compared with others. The state of charge not quite 6AH. I have roughly 1/3 acre and need at least 3 batteries to mow each time.

This cheap battery is not worthless. Lasted less than a year in very light usage.
