Rechargeable Batteries for Lawn Mowers: Power and Performance
Battery technology is the heart of cordless mower performance. Understanding battery specifications helps match power systems to your specific requirements:
Battery Voltage Explained
Voltage is a primary indicator of a mower’s power potential:
- 36-40V: Entry-level systems suitable for small to medium lawns
- 56-60V: Mid-range systems balancing power and affordability
- 80-82V: Professional-grade systems for larger properties or demanding conditions
Higher voltage generally translates to more cutting power, particularly when tackling thick or tall grass. However, ampere-hour (Ah) rating determines runtime.
Battery Capacity and Runtime
Ampere-hour ratings indicate energy storage capacity:
- 2.0-3.0Ah: Suitable for small lawns (under 5,000 sq ft)
- 4.0-6.0Ah: Ideal for medium lawns (5,000-10,000 sq ft)
- 7.0-12.0Ah: Designed for large properties or professional use
Actual runtime varies based on:
- Grass height and density
- Cutting modes (mulching requires more power)
- Self-propulsion usage
- Terrain (slopes consume more energy)
- Weather conditions
For context, a 5.0Ah battery at 56V typically provides 30-40 minutes of continuous mowing in moderate conditions.
