Greenworks PRO 80V 21-Inch Push Mower + 16-Inch String Trimmer, (2) 2.0 AH Batteries and Charger Included 1314402HD Mower/String Trimmer

While some users report positive long-term experiences, with mowers performing well after two seasons or more, specific quantitative data on the motor's operational lifespan (e.g., total hours of use) or the exact degradation curve of the 80V lithium-ion cells under extreme stress is not widely documented. Brushless motors generally offer extended longevity over brushed designs due to reduced wear. However, without defined testing protocols (e.g., Mean Time Between Failures for motor components, cycle life for batteries under varied discharge rates), precise long-term durability predictions remain an area for user observation.

The impact of sub-freezing temperatures on Greenworks 80V battery performance is not extensively detailed in user discussions. Lithium-ion batteries, including those in the 80V system, typically experience reduced capacity and slower discharge rates in cold conditions, potentially lowering runtime below -5°C. While the 80V system's solid power may compensate for some drag, users should anticipate a noticeable decrease in operational duration compared to performance at standard ambient temperatures (20°C).
