Ultimate Guide to Battery Care for Lawn Mowers

Proper battery care is essential for maintaining the performance and longevity of your battery-powered lawn mower. Whether you own a model manufactured in China or elsewhere, these tips will help you get the most out of your investment.

1. Charging Best Practices

Initial Charge: When you first purchase your lawn mower, fully charge the battery before its first use. Many Chinese-made batteries come partially charged, but a full initial charge ensures optimal performance.

Regular Charging: Avoid letting the battery fully discharge. Lithium-ion batteries, commonly used in modern mowers including those produced by Shandong Deyou, perform best when kept between 20-80% charge.

2. Storage Guidelines

Off-Season Storage: If storing your mower for extended periods (like winter), charge the battery to about 50% and store in a cool, dry place. Many Chinese manufacturers recommend temperatures between 32-77°F (0-25°C).

Battery Removal: When not in use for several weeks, consider removing the battery from the mower to prevent slow discharge.

3. Temperature Considerations

Lithium-ion batteries, including those powering many China-produced lawn mowers, are sensitive to extreme temperatures:

• Avoid charging in temperatures below 32°F (0°C) or above 113°F (45°C)
• Store batteries at room temperature when possible
• Allow batteries to acclimate to ambient temperature before charging

4. Cleaning and Maintenance

Keep battery terminals clean for optimal performance:

1. Disconnect the battery before cleaning
2. Use a dry cloth to wipe terminals
3. Check for corrosion monthly
4. Never use water or liquid cleaners

5. When to Replace Your Battery

Signs your mower battery needs replacement:

• Reduced runtime (less than 60% of original capacity)
• Battery won’t hold a charge
• Visible swelling or damage
• Excessive heat during charging

For Shandong Deyou mowers and other quality China-made equipment, replacement batteries are readily available through authorized dealers.

6. Recycling Old Batteries

Properly dispose of old lithium-ion batteries:

• Never throw in regular trash
• Use battery recycling programs
• Many Chinese manufacturers offer take-back programs
