What is a lithium battery for lawn mower?

A lithium battery lawn mower, including a motor that drives a cutting blade, the motor is connected to a control system, and the control system is connected to a power supply; said motor is a DC motor, said power supply is a lithium battery pack, and the DC motor is connected to the lithium battery pack through the control system.

UL standard published bilateral U.S. – Canadian standard ANSI/CAN/UL 62841-4-3, electric hand tools, portable tools, and lawn and garden machinery – safety – Part 4-3: Walk-behind control push mowers special requirements
Overview of safety requirements and testing criteria for electric walk-behind mowers
This standard provides safety and structural requirements, as well as required testing, to help ensure the safe use, care, and maintenance of electric walk-behind mowers. It covers rotary and cylinder walk-behind mowers, as well as models with metallic and non-metallic cutting devices. It also applies to battery-powered and plug-in mowers.

The lifespan of an electric lawn mower battery depends on the type of battery and how often it is used. For lithium-ion batteries, the typical service life is 3,000 to 5,000 charge/discharge cycles or about 10 to 15 years. Lead-acid batteries are in the 500-1000 range, with a service life of 2-3 years. Proper use and maintenance can extend the life of the battery.

Decreased range: The operating time of the battery is significantly reduced when fully charged.
Reduced charging efficiency: The battery takes longer to charge or fails to reach a full charge.
Battery swelling or damage: There is obvious swelling, cracking, or damage in appearance.
Unstable performance: Battery performance is unstable during use.

Avoid overcharging: Do not charge the battery to 100% for a long period of time and keep charging.
Appropriate Charging Cycles: Plan charging cycles according to the frequency of use and try to start charging when the battery is below 20%.
Use the right charger: Use the charger recommended or provided by the manufacturer.
Monitor charging status: Monitor the battery temperature and charging status during the charging process.

Charge in a suitable environment: Charge in a dry, well-ventilated area and avoid charging in high temperatures or direct sunlight.
Avoid contact with water: Make sure the charging area is away from water sources.
Don’t stay behind: Try to be present during charging so that problems can be dealt with immediately.
Check cords and plugs: Make sure cords and plugs are undamaged and avoid using extension cords.

Use it wisely: Avoid frequent short bursts of use and try to complete mowing jobs in one go.
Keep the battery clean: Clean the battery and connection points regularly to ensure good electrical contact.
Suitable storage: Store the battery in a dry, cool place during non-use periods.
Avoid extreme temperatures: using the battery at extremely high or low temperatures will affect its efficiency and life expectancy

Use the correct charger: always use the manufacturer’s recommended charger for battery safety and efficiency.
Avoid overcharging: Do not exceed the recommended charging time to prevent overcharging the battery.
Monitor charging temperature: Ensure that the charging environment is well-ventilated to avoid overheating the battery.
Check after charging: Check the battery for overheating, swelling, or other abnormalities after charging is complete.

Use a Battery Management System (BMS) to ensure battery stability under various loads.
Regularly check the battery and battery connections to ensure good connections and no corrosion or looseness.

Store in a dry, cool, ventilated area away from direct sunlight and high temperatures.
Charge the battery to approximately 50% charge before long-term storage to prevent over-discharge of the battery.

Fully charge the battery down to approximately 50% charge.
Check the battery level every few months and recharge it if necessary.

Flexibility and expandability: The modular design makes it easier to replace and upgrade batteries.
Easy maintenance: when individual modules are damaged, it is possible to replace only the damaged module instead of the entire battery pack.
Customized performance: different numbers of battery modules can be combined as needed to meet specific performance requirements.

Regularly check all battery connections and interfaces to ensure they are not loose or damaged.
Use appropriate tools and techniques for battery installation to ensure stable connections.
Avoid violent vibrations or impacts, which can cause connections to loosen.

Family use: For general family use, a battery with medium capacity and endurance can meet the demand.
Commercial use: For commercial or professional gardening work, batteries with higher capacity and durability may be required to support longer periods of continuous use.
Varying Terrain: In uneven or weedy terrain, a more powerful battery may be needed to provide adequate power.
