As the mowing season winds down and winter approaches, proper storage of your battery-powered lawn mower is essential to ensure its longevity and readiness for spring. Unlike gas mowers that require extensive fuel system preparation, battery models have a simpler winterization process, primarily focusing on battery care and general cleanliness. A few simple steps can prevent common issues like battery degradation, rust, and pest damage, saving you time and money in the long run.
Why Winter Storage is Crucial
Even though battery powered lawn mower are less demanding than their gas counterparts, neglecting winter storage can still lead to problems:
- Battery Degradation: Lithium-ion batteries, while robust, can suffer reduced lifespan and capacity if stored improperly, especially at extreme temperatures or at full/empty charge.
- Corrosion and Rust: Moisture and condensation can lead to rust on metal components like the deck, blade, and fasteners.
- Plastic and Rubber Damage: Extreme cold can make plastic parts brittle and cause rubber seals to crack.
- Pest Infestation: Mowers can become attractive nesting spots for rodents and insects, potentially causing damage to wiring or other components.
Essential Steps for Winter Storage
Follow these guidelines to properly prepare your battery-powered lawn mower for its winter slumber:
1. Battery Care (Most Critical Step)
The battery is the heart of your electric mower, so its proper storage is paramount.
- Remove Batteries: Always remove the battery pack(s) from the mower itself. Do not leave them installed in the mower during storage.
- Optimal Charge Level: For lithium-ion batteries, the ideal storage charge is typically around 50-60%. Storing them fully charged for extended periods can stress the cells, while storing them completely depleted can lead to “deep discharge,” which can permanently damage the battery and prevent it from holding a charge.
- Cool, Dry Storage: Store batteries in a cool, dry place with stable temperatures. Avoid unheated garages or sheds where temperatures can drop below freezing, as well as areas exposed to direct sunlight or excessive heat. A climate-controlled basement or closet is often ideal.
- Avoid Moisture: Keep batteries away from any sources of moisture or humidity.
2. Thorough Cleaning
Before storing, give your mower a comprehensive clean.
- Deck and Blades: Disconnect the battery (and ensure it’s removed!). Tip the mower onto its side (consult your manual for the correct side to avoid fluid leaks if any). Scrape off any caked-on grass clippings, mud, and debris from the underside of the deck. This prevents corrosion and mold growth.
- Exterior Surfaces: Wipe down the entire exterior of the mower, including the handles, wheels, and motor housing, to remove dirt, dust, and sap.
- Air Vents: Ensure any air vents or cooling fins around the motor are clear of debris to prevent blockages.
- Blade Inspection: Inspect the blade for any damage, nicks, or dullness. Consider sharpening or replacing the blade now, so it’s ready for spring. If you sharpen it yourself, ensure it’s balanced.
3. Inspect for Damage and Lubricate
Use this opportunity to perform a quick check-up.
- Check Fasteners: Tighten any loose screws, bolts, or connections on the handle, wheels, and deck.
- Inspect Components: Look for any cracks in the plastic housing, wear on the wheels, or damage to the handle assembly. Addressing minor issues now can prevent larger problems later.
- Lubricate: Apply a light coat of silicone spray or a general-purpose lubricant to any exposed metal pivot points, height adjustment levers, and wheel axles to prevent rust and ensure smooth operation.
4. Choose the Right Storage Location
The environment where you store your mower is crucial.
- Dry and Ventilated: Select a clean, dry, and well-ventilated area. Avoid damp basements or areas prone to significant temperature fluctuations.
- Protected from Pests: If storing in a shed or garage, consider covering the mower with a breathable tarp or placing it in a large, sealed plastic bag to deter rodents and insects from nesting inside.
- Compact Storage: Many battery mowers feature folding handles or can be stored vertically, saving valuable space.
Conclusion
Proper winter storage for your battery-powered lawn mower is a straightforward process that primarily revolves around diligent battery care and thorough cleaning. By following these steps, you can safeguard your investment, extend the life of both your mower and its batteries, and ensure a smooth, hassle-free start to the next mowing season.
