Why Is It Necessary to Jumpstart a Lawn Mower?
Jumpstarting a lawn mower is necessary when its battery is depleted, preventing the engine from starting. A jumpstart provides the required power to start the mower and restore its functionality.
According to the Outdoor Power Equipment Institute (OPEI), a reputable organization that represents manufacturers of outdoor power equipment, a lawn mower typically uses a lead-acid battery, which can lose charge over time due to lack of use or cold temperatures.
Several underlying causes contribute to the need for jumpstarting. The most common reason is a drained battery. When the mower sits unused for extended periods, such as through winter, the battery can lose its charge. Additionally, cold temperatures can slow down the chemical reactions within the battery, reducing its efficiency. Faulty electrical components or a malfunctioning charging system can also contribute to a low battery charge.
The lead-acid battery is the most commonly used type in lawn mowers. It relies on a chemical reaction between lead and sulfuric acid to store and provide electrical energy. When this battery is discharged, the chemical reaction can no longer occur efficiently, making it impossible to start the engine. Jumpstarting temporarily restores the chemical balance by providing external power.
Specific conditions leading to a drained battery include not using the mower frequently or leaving it inactive for months. Cold weather, particularly below freezing, can exacerbate battery issues. For instance, a lawn mower left outside during winter may require a jumpstart in the spring, as its battery will likely have discharged during the cold months. Regular maintenance, such as checking the battery charge and ensuring proper storage, can prevent the need for jumpstarting.
