Last NO longer than a factory battery - Over rated and under delivers
4.0Ah, 80Wh (watt hrs) is stamped right on the battery pack as seen on one of the Biswaye advertised images. The factory B&D battery is rated at 1.0Ah, 30Wh, and last 15 to 20 mins. This battery lasts NO longer than 20 mins on the B&D leaf blower. Personally, it's very overrated and by all accounts should last 3 to 4x longer based on the information above. BUT, it does not. That's the Chinese for you, over-rate and under-deliver. I still think its a great value for the money compared to spending over $40 for a factory battery. Many batteries on Amazon are similarly rated between 2.0Ah to 4.0Ah and are no different. If you want a "true 40 min" lasting battery you need to buy the taller or "double-wide" one which I own and it's rated at 3.0Ah. Size does matter! LOL

Great buy
I didn't know what to expect but for the price it was worth a try. As soon as I used this battery in my weed wacker (B&D) I realized how worn out the original battery was. I could only weed wack for 5-7 mins at minimum capacity with the original. This battery is powerful and goes on forever. It seems to even fit the weed wacker better. I don't have to struggle to get it in place. Uses the same charger I had and charges quickly. I am happy.
