Battery capacity, measured in amp-hours (Ah), determines how long your tools can run on a single charge. Higher capacity batteries (such as 4.0 Ah found in the Festool 577619 Cordless Drill C 18 HPC 4,0 I-Set) offer extended runtime for demanding or prolonged jobs, while lower capacities result in lighter tools for shorter, precision-focused tasks. Kits like the Festool 576869 Cordless Drill CXS 12 2,5-Set use 2.5 Ah batteries for ultra-portability. With multiple battery capacities across the product range, you can select the right balance between weight and longevity for your drill combo kit workflow.
