Overall, customers are satisfied with Black & Decker's HPB18 18-volt slide-pack battery, giving it an average rating of four out of five stars. Dissatisfied customers, however, say the battery runs down quickly and loses its ability to hold a charge over time.
According to more than 200 reviews on Amazon.com, most customers are happy with this product, saying it works well as a replacement battery for their Black & Decker power tools. Many reviewers said their tools perform better with the new battery and that it seems to provide more power than the original battery.
While most customers said the battery works as advertised, some were disappointed by its short charge life and lack of durability. Some reviews said the battery runs down after 15 to 30 minutes of use even after a full day of charging and loses its ability to charge in less than a year. Many critical reviews note that this battery is of much lower quality than the original battery purchased with the tools.
The HPB18 battery is made with high output nickel cadmium battery cells with "no memory" technology, which can provide up to 500 recharges, according to Black & Decker. The batteries are spring-loaded for easy installation, and they are compatible with all spring-loaded battery style Firestorm and Black & Decker 18-volt products.
