• Are less prone to "memory effect" degradation
• Offer higher energy density and longer lifespan PowerSmart USA

Signs of Battery Degradation

Consider replacement when the battery:

• Becomes noticeably harder to start
• Loses its charge significantly faster than previously
• Shows declining performance after several seasons RD Batteries

Cost Difference Between Electric and Gas Mowers

Initial Purchase Price

According to Consumer Reports, gas mowers can cost less upfront compared to battery-powered electric mowers. This lower initial cost represents one of the primary advantages gas mowers have traditionally offered consumers.

However, this cost advantage is becoming less significant as battery technology advances. Bethel Power notes that "with battery technology advancing fast, electric models are closing the gap" in terms of overall cost competitiveness.

When evaluating total cost of ownership, comprehensive equipment solutions—like those available in our Electric Battery Powered collection—provide flexibility across multiple price points and performance levels for both residential and commercial applications, allowing you to find the right fit for your budget and lawn care needs.

Long-Term Operating Costs

Overall cost considerations should extend beyond just the purchase price:

Maintenance Costs: Fields Equipment indicates that gas mowers require significantly more maintenance than electric mowers, which require "very little maintenance, mostly just periodic sharpening of the blades." This maintenance differential can significantly impact total cost of ownership over time.

Fuel and Operating Costs: While not explicitly quantified in available results, gas mowers require ongoing fuel purchases, whereas electric mowers primarily require electricity for charging.

Note: The search results do not provide specific dollar amounts for the cost differences between these two types of mowers.

Electric Mower Power for Thick Grass

Real-World Performance

According to Consumer Reports, modern electric mowers handle demanding mowing tasks effectively. Consumer Reports' lab testing evaluates gas and electric walk-behind mowers on cutting evenness, side discharging, mulching, bagging, and handling, finding that "each type has an edge in some performance tests." For the average lawn, a fully charged battery walk-behind mower will complete the job the same as a gas one.

Battery Power and Capability

Modern electric mowers come equipped with advanced technology and sufficient power for typical residential use. Popular Mechanics notes that today's cordless lawn mowers are "powerful, convenient, and (relatively) quiet," with models that "cut well, run long, and are easy to use and maintain."

For demanding applications—thick grass, steep slopes, and large properties—commercial-grade solutions deliver the horsepower and torque that standard residential equipment cannot match. Our Self Propelled Mowers collection includes zero-turn mowers and high-capacity battery systems engineered to tackle professional-grade tasks while maintaining the environmental advantages electric technology provides.

Specific examples of competitive equipment include the PowerSmart 80V 22" Brushless Cordless Self-Propelled Lawn Mower, which according to PowerSmart USA, features "strong rear-wheel drive" and can handle slopes up to 20 degrees with multiple cutting options including mulching, bagging, or side discharge.

Important Considerations

While electric mowers have adequate power for thick grass in most scenarios, battery runtime remains a practical consideration for larger properties. The key factor is ensuring the battery capacity matches your lawn size to avoid needing a recharge mid-mowing session.

Savings with Electric Mowers
