The service life of the battery of an electric remote-controlled lawn mower depends on three core dimensions: charging and discharging habits, storage environment, and daily maintenance. Following the maintenance points below can extend the battery cycle life by 30%–50%.
Do not leave the battery plugged in for long-term trickle charging after charging. Unplug the power supply promptly when the battery is fully charged (the charger indicator turns green); overcharging will accelerate the aging of chemical substances inside the battery.
It is strictly forbidden to charge the battery only after it is completely depleted (when the device shuts down automatically). A depleted state will cause "voltage collapse" of the lithium battery, permanently damaging the cell capacity. The optimal charging time is when the remaining power is 20%–30%.
The suitable temperature for battery charging is 10℃–30℃. Avoid charging in high-temperature (>40℃) or low-temperature (<0℃) environments.
In summer, do not charge the battery under direct sunlight; in winter, place the battery in a room-temperature environment to stand for 1–2 hours before charging.
Must use the original charger matched with the model. Non-original chargers have mismatched voltage and current parameters, which will cause fast or slow charging and damage the battery cells.
Avoid mixing chargers of different brands and models.
Try to avoid long-term full-load operation on steep slopes or areas with tall weeds and dense shrubs. High-current discharge will cause the battery temperature to rise sharply and accelerate cell attenuation.
When working on complex terrain, appropriately shorten the single operation time and complete the work in segments.

Charge the battery to 50%–60% before storage. This is the "safe power level" for lithium batteries, which can prevent power depletion caused by self-discharge.
Remove the battery and store it separately in a dry, ventilated, and cool environment, away from heat sources (such as radiators and stoves) and flammable and explosive materials.
Recharge the battery every 1–2 months to maintain the power at around 50%, avoiding cell failure due to excessively low voltage.
Do not store the battery with metal objects (such as keys and scissors) to prevent short circuits between the positive and negative electrodes, which may cause heat generation and fire.
Prevent the battery from getting damp or exposed to rain; cover it with a dry plastic bag for moisture protection during storage.
Regularly wipe the metal contacts of the battery and the machine body with a dry soft cloth to remove dust, soil, or oxide layers. Poor contact of the contacts will lead to unstable power supply and increase the battery load.
If the battery surface is stained with soil or weed sap after operation, wipe it clean with a damp cloth to avoid corrosive substances adhering to and damaging the battery casing and interface.
Battery cells are fragile; severe impact or falling will damage the internal structure. Handle the battery gently when picking and placing it daily; do not press or throw it.
The internal structure of a lithium battery is complex. Unauthorized disassembly will damage the protection circuit and cause safety hazards such as short circuits and fires. If the battery has faults such as bulging or leakage, contact the manufacturer's after-sales service for handling.
The battery generates abnormal heat or has a pungent odor during charging;
The battery casing is bulging, deformed, or leaking;
The battery life drops sharply suddenly during equipment operation.
