Reliable power for your Kobalt 40V tools

Meet the FSKE 6.0Ah Replacement Battery, a two-pack designed to renew your Kobalt 40V toolkit. Built with premium cells and a smart protection system, this kit aims to deliver dependable performance across yard work and outdoor projects.

Power and efficiency

Each pack delivers 6000mAh at 40V, and the combined setup can offer up to 50% more power than typical OEM 4.0Ah options. In real-world use, you may experience longer runtimes between charges, especially during heavy tasks like mowing tall grass or blowing leaves.

  • 4 LED indicators show 25%, 50%, 75%, and 100% charge for quick checks.
  • High-quality A+ cells support consistent power delivery across cycles.
  • Smart BMS guards against short circuits, overcharging, and overheating.
  • Durable PC+ABS shell with a fire rating and heat-dissipation vents.

Compatibility and ease of use

Designed to work with Kobalt 40V power tools, including lawn mowers, chainsaws, string trimmers, and leaf blowers, as well as common 40V chargers like KRC60-06, KRC40-06, and KRC840-03. The LED indicators help you judge runtime at a glance.

  • Wide compatibility with Kobalt 40V tools and chargers for a flexible setup.
  • Clear LED readouts for quick status checks on the job site.
