The Complete Guide to Lawn Mower Battery Maintenance

Proper battery care is essential for keeping your lawn mower running efficiently season after season. Whether you own a Chinese-made mower or premium international brands, these universal tips will help maximize your battery’s performance.

Understanding Your Mower’s Battery

Modern lawn mowers typically use lithium-ion or lead-acid batteries. Shandong Deyou and other manufacturers now produce advanced battery systems that require specific care routines.

Battery Type Comparison:

Seasonal Storage Tips

Proper storage is crucial whether you’re putting your mower away for winter or just between uses. Many Chinese manufacturers including those in Shandong province recommend:

1. Clean terminals: Remove corrosion with baking soda solution
2. Partial charge: Maintain 40-60% charge during storage
3. Climate control: Store in dry area between 32-77°F
