I was able to mow my 1/4 acre lawn with this battery and a 5.0 AH battery without having to stop to recharge like I have had to do in the past. LOVE IT!
Lasted 25 to 30 minutes,I was expecting it to last longer

Hello James M P,
We are sorry to hear that you were not completely satisfied with the run time of this battery. The run time varies depending on the tool that it is being used in but also the load acting against the unit while in use. We would be happy to investigate to see whether your run time would be considered average; please kindly contact our customer support team by sending an email through the customer contact page located on our website or by phone at 1-888-909-6757.
This newer version of 40 Amp battery is even better than the original supplied with our mower. We mow over an acre, so one battery was not quite enough. This one is faster charging and lasts about 45 minutes.
I bought this about a month ago. I like the power and the light weight. It does a really good job. I just wish it had a wheel in the front and rear of the cutting area to balance it better when the blade is turning. But I still like it.
