Leaving batteries in a lawn mower for extended periods can have significant implications on the overall performance and lifespan of the device. As a lawn mower owner, it is essential to understand the factors that influence battery longevity and the recommended practices for maintaining your lawn mower’s batteries. In this article, we will delve into the world of lawn mower batteries, exploring the different types, their characteristics, and the effects of leaving them in the device for an extended duration.
Understanding Lawn Mower Batteries
Lawn mower batteries are designed to provide the necessary power to start and operate the engine. These batteries are typically lead-acid batteries, which consist of a series of cells filled with a mixture of water, sulfuric acid, and lead plates. The lead plates are responsible for storing electrical energy, while the sulfuric acid acts as an electrolyte, facilitating the flow of ions between the plates. Lawn mower batteries are classified into different types, including:
Lead-Acid Batteries
Lead-acid batteries are the most common type of battery used in lawn mowers. They are relatively inexpensive, easy to maintain, and provide a reliable source of power. However, they have a limited lifespan and require regular maintenance to ensure optimal performance. Lead-acid batteries are further divided into two subcategories: maintenance-free and maintenance-accessible batteries. Maintenance-free batteries are sealed units that do not require regular checks or maintenance, while maintenance-accessible batteries have removable caps, allowing users to inspect and maintain the cells.
Lithium-Ion Batteries
Lithium-ion batteries are a newer type of battery used in some lawn mowers. They offer several advantages over lead-acid batteries, including a longer lifespan, lighter weight, and higher energy density. Lithium-ion batteries are also more environmentally friendly, as they do not contain toxic materials like lead or sulfuric acid. However, they are more expensive than lead-acid batteries and may require special charging and maintenance procedures.
The Effects of Leaving Batteries in a Lawn Mower
Leaving batteries in a lawn mower for an extended period can have severe consequences on the battery’s performance and lifespan. Some of the effects of leaving batteries in a lawn mower include:
Self-Discharge
Batteries naturally self-discharge over time, even when not in use. This process occurs as the battery’s internal chemicals react with the surrounding environment, causing the battery to lose its charge. Self-discharge rates vary depending on the type of battery, temperature, and storage conditions. Lead-acid batteries typically self-discharge at a rate of 1-2% per day, while lithium-ion batteries self-discharge at a rate of 0.5-1% per day.
Corrosion and Sulfation
When a battery is left in a lawn mower for an extended period, the terminals and connectors can corrode, leading to a decrease in performance and potentially causing the battery to fail. Corrosion occurs when the battery’s terminals react with the surrounding environment, forming a layer of oxide or sulfate. Sulfation, on the other hand, occurs when the battery’s plates become coated with a layer of lead sulfate, reducing the battery’s ability to hold a charge.
Depth of Discharge
The depth of discharge (DOD) refers to the percentage of a battery’s capacity that is used before it is recharged. Leaving a battery in a lawn mower for an extended period can cause the battery to be deeply discharged, leading to a reduction in its lifespan. Deeply discharging a battery can cause the internal chemicals to become unbalanced, leading to a decrease in performance and potentially causing the battery to fail.
How Long Can You Leave Batteries in a Lawn Mower?
The length of time you can leave batteries in a lawn mower depends on various factors, including the type of battery, storage conditions, and maintenance practices. As a general rule, it is recommended to remove the battery from the lawn mower and store it in a cool, dry place during the off-season. This helps to prevent self-discharge, corrosion, and sulfation, ensuring the battery remains in good condition.
Storage Conditions
Storage conditions play a critical role in determining the lifespan of a lawn mower battery. Ideally, batteries should be stored in a cool, dry place, away from direct sunlight and moisture. The storage area should be well-ventilated, and the battery should be kept away from any flammable materials. The recommended storage temperature for lead-acid batteries is between 40°F and 70°F (4°C and 21°C), while lithium-ion batteries should be stored at a temperature between 32°F and 80°F (0°C and 27°C).
Maintenance Practices
Regular maintenance is essential to ensure the longevity of a lawn mower battery. This includes checking the battery’s terminals and connectors for corrosion, cleaning the terminals and connectors as needed, and applying a layer of petroleum jelly or silicon-based lubricant to protect the terminals from corrosion. Additionally, the battery should be charged regularly, following the manufacturer’s recommended charging schedule.
Charging and Maintenance Schedule
To maintain the health and longevity of a lawn mower battery, it is essential to follow a regular charging and maintenance schedule. This includes:
Checking the battery’s electrolyte level and adding distilled water as needed
Cleaning the terminals and connectors
Applying a layer of petroleum jelly or silicon-based lubricant to protect the terminals from corrosion
Charging the battery regularly, following the manufacturer’s recommended charging schedule
By following these maintenance practices and storing the battery in a cool, dry place, you can help extend the lifespan of your lawn mower battery and ensure it remains in good condition.

How long can I leave batteries in a lawn mower without damaging them?
Leaving batteries in a lawn mower for an extended period can be detrimental to their overall health and lifespan. If the mower is not used for several months, it is recommended to remove the batteries to prevent deep discharge, which can cause irreversible damage. Deep discharge occurs when the battery is completely drained, and if left in this state for an extended period, it can lead to a significant reduction in the battery’s capacity and overall lifespan. It is essential to check the batteries regularly, especially during the off-season, to ensure they are not damaged due to prolonged disuse.
To minimize the risk of damage, it is recommended to remove the batteries from the lawn mower and store them in a cool, dry place. The batteries should be charged to about 40% capacity before being stored, as this will help to slow down the self-discharge process. It is also crucial to check the battery terminals for any signs of corrosion or damage, as this can prevent the battery from functioning properly when the mower is next used. By following these simple steps, you can help to extend the lifespan of your lawn mower’s batteries and ensure they remain in good working condition when you need them.
What happens if I leave the batteries in my lawn mower over the winter months?
Leaving batteries in a lawn mower over the winter months can be particularly damaging, as the cold temperatures can exacerbate the self-discharge process.
