Lawn and Garden β FAQ
How long do cordless mower batteries actually last?
Real-world runtime ranges from 25 minutes for 20V models to 45 minutes for 40V and 80V units. Battery age, grass thickness, and moisture impact performance. Most 4.0Ah batteries last 3-5 years with proper storage.
What voltage do I need for my backyard size?
Under 2,500 sq ft: 20-24V works. 2,500-7,500 sq ft: 40-48V recommended. Over 7,500 sq ft: 80V self-propelled models prevent fatigue. Dense or wet grass requires higher voltage regardless of size.
Are self-propelled mowers worth the extra cost?
Yes for yards over 5,000 sq ft or with slopes over 10 degrees. Self-propulsion reduces pushing effort by 70% and cuts mowing time. Not essential for flat, small lawns where push mowers cost less and store easier.
Can cordless mowers cut tall or wet grass?
80V and 48V models handle 6-inch grass if you cut in stages. Wet grass clogs any mower and risks battery damage. Always mow dry grass for best results and equipment longevity.
How do I maintain a cordless lawn mower?
Clean the deck after each use, sharpen blades annually, store batteries indoors at 50% charge in winter, and keep contacts clean. No oil changes or spark plugs neededβmajor advantage over gas.
What's the difference between brushed and brushless motors?
Brushless motors are 30% more efficient, generate less heat, and last longer than brushed designs. They adjust power output based on grass resistance, extending battery life. All premium mowers now use brushless technology.
