What Customers Are Saying

Customers praise the battery's exceptional charge retention, with most completing entire yards on a single charge and appreciating fast charging under an hour. Many highlight excellent compatibility across 40V tools and well-balanced ergonomics that reduce fatigue. However, a notable minority report serious failures including leakage, premature degradation, and batteries lasting only one season. Despite these defects, most customers consider the battery's performance and convenience worthwhile, though reliability concerns deter some from recommending it.

Cordless without having to stop and charge

[This review was collected as part of a promotion.] Love that the battery recharges quickly (compared to other brands and sizes that I own). It held a charge for 45 minutes to an hour, depending on how intensely I was using it, so I was super excited that I didn’t have to stop what I was doing!
