Greenworks 60V 8.0 Ah UltraPower Bluetooth Lithium-Ion Battery

Hello Venice Miller. We are sorry to hear about your experience. A lithium-ion battery lifespan is determined by charging and discharging cycles and is dependent on many different variables such as storage, temperature, charge, and handling. A “normally” used battery can last over 1000 cycles. A cycle means that the battery goes from fully charged to empty and then fully charged again. A battery is considered a consumable and over time may lose the ability to store the same amount of energy as it did at the beginning of its life cycle. In optimal conditions 80V lithium-ion batteries typically have a lifespan of up to 2,000 charging and discharging cycles (1,000 with a rapid charger). While we only work with the highest quality products, nothing is always perfect, but not to worry, Greenworks lithium-ion batteries are offered with a 4-year (homeowner) limited warranty.
