Customer feedback describes the batteries as good quality and value, with reports of useful capacity, quick charging, good fit, and operation in tools such as drills, weed trimmers, and leaf blowers. Those reports are relevant for buyers using the stated V20 platform, but charge time and runtime depend on the charger, tool, and workload. Aggregate ratings are mostly five-star, though a small share are low-star ratings, and ratings alone do not explain those experiences.

Positive themes

  • Feedback reports good fit and performance in several CRAFTSMAN tools.
  • Customers describe useful battery capacity and quick charging.
