Why use battery verses Internal Combustion Engine (ICE)?
If you have never used an electric/battery mower, one of the first things you will notice is a significant reduction in the amount of noise. Even new ICE mowers produce high levels of noise which can induce temporary or long-term permanent hearing loss. Exposure to loud noise can also contribute to an increase in stress levels.
You will enjoy and appreciate how quietly an electric/battery mower performs and soon become aware of how loud and obnoxious your neighbor's equipment is. The owners of electric/battery mowers do not send the neighborhood dogs, cats, and small children running for safety when the machine is brought out to mow.
Work energy produced using a battery/motor system is far more efficient than ICE systems. Approximately 46% of the electrical energy taken from a wall plug to charge a battery-pack is delivered as useful work. ICE engines are only about 18% efficient when doing the same amount of work.
Though both electricity and liquid based fuel prices are increasing, electricity is far less expensive and its price is far less volatile. When you compare mowing the same yard, recharging the battery-pack may run about 40 cents (depending on your Kw/hr price) verses $6.00 when replacing two gallons of gasoline at $3.00 per gallon.
The operational cost savings of an electric/battery mower will actually pay for the machine long before the end of its useful life.
According to the United States Environmental Protection Agency (EPA), gasoline-powered landscape equipment (mowers, trimmers, blowers, chain saws) account for more than 5 percent of urban air pollution. The EPA also says a new motorized push mower can produce as many hydrocarbons - a major pollutant - in one hour as 11 new cars! A new riding mower's polluting can equal an hour's worth of pollution from 34 new cars.
Each weekend, roughly 54 million Americans mow their lawns using 800 million gallons of gasoline per year. Furthermore, the EPA estimates that 17 million gallons of fuel are spilled each year just refueling such equipment -- more than the amount spilled by the Exxon Valdez in the Gulf of Alaska in 1989.
Although generation of electricity has environment issues, it is more effective and efficient to control pollution at one smoke stack than thousands of tailpipes.
Additionally, recharging can be accomplished using small backyard solar and wind generation systems essentially eliminating pollution all together.
Once the battery-pack has reached the end of its useful life, it can easily be recycled.
About 60% of the oil consumed in the United State is currently imported. Using electric/battery power will reduce oil consumption and relies on an energy source which is derived from diversified sources using local resources.
There are no engine oil or filter, air-filter, fuel-filter, or spark plugs to change. No tune-ups are required.
Batteries and DC motors have a track record of be being durable and dependable.
Emergency Backup Power Source
When combined with a DC to AC inverter, the battery-pack can serve as a dependable source of emergency power if there is a loss of commercial power. A mobile battery-pack can also provide power far from available outlets.
