Buying Guide For 20 Inch Battery Chainsaws
When selecting a 20 inch battery chainsaw, consider multiple factors to ensure the right fit for your needs.
Power and Motor Type
Look for chainsaws with brushless motors as they provide better efficiency, higher torque, and longer motor life than brushed models. Also, check the power equivalency to gas chainsaws—models mimicking 50cc to 55cc gas engines offer robust cutting performance.
Battery Voltage and Capacity
Higher voltage batteries (60V, 80V, or 82V) generally provide more power but may be heavier. Battery capacity (measured in Ah) directly impacts runtime. For extended work, choose chainsaws offering batteries with 6.0Ah or more. Some models come bundled with batteries and chargers, while others require separate purchases.
Cutting Capacity and Bar Length
A 20-inch bar length is suitable for medium to large cutting tasks like tree limbs, pruning, and firewood. The chain pitch and gauge (common are 3/8-inch pitch and 0.050-inch gauge) influence cutting speed and smoothness. Full chisel tooth chains cut more aggressively, ideal for seasoned wood.
Safety Features
Essential safety features include mechanical chain brakes for kickback protection, wrap-around ergonomic handles for control, and automatic chain oilers to maintain optimal chain lubrication while cutting.
Runtime and Charging
Runtimes vary significantly; some units offer over 200 cuts per single charge, while others can reach beyond 400. Consider how often you need to recharge and whether rapid chargers or multiple batteries are included. This affects productivity during extended jobs.
Additional Considerations
- Weight and Ergonomics: Lightweight chainsaws reduce fatigue during long use.
- Maintenance: Tool-less chain tensioning and easy oil refills simplify upkeep.
- Compatibility: Battery compatibility with other tools in the same brand ecosystem adds value.
- Warranty and Support: Consider the brand’s warranty policy and customer support availability for peace of mind.
