How long will a full 5.0Ah charge run me on typical outdoor tasks?

Runtime varies by tool and workload, but a 5.0Ah pack gives extended operation compared with lower-capacity 40V cells, helping you complete larger jobs before swapping or recharging. The high-capacity cells are optimized for steady output so power doesn't sag quickly under normal loads.

• 5.0Ah capacity for extended cutting, trimming, or drilling sessions.
• Stable voltage delivery helps maintain tool performance under load.
• LED fuel-gauge shows remaining charge so you can plan work and recharges.
• Recharge as needed without memory effect—top-up charging supported.
