Key factors affecting battery life:
1. Battery type: Lead-acid batteries are low-cost but have a short lifespan (approximately 300-400 cycles); lithium batteries have high energy density and a long lifespan (lithium iron phosphate batteries can reach 2000 cycles).
2. Usage habits:
Avoid deep discharge: Charge when the battery level is 20%-30%, don't wait until it's completely depleted.
Control charging time: Charge lead-acid batteries for 6-8 hours, lithium batteries for 4-6 hours, avoid overcharging.
Reduce high-current discharge: Avoid rapid acceleration and overloading to reduce the battery's burden.
3. Environmental factors: The optimal battery operating temperature is 0°C-40°C. Avoid direct sunlight in summer and keep the battery warm in winter.
How to determine if the battery needs replacing?
1. Sudden drop in range: A new battery could run 100 kilometers, now it only runs about 30 kilometers.
2. Rapid power loss: The battery level drops sharply when you twist the throttle.
3. Physical damage: Battery bulging, leakage, or crystallization.
Tips to extend battery life:
1. Develop good habits: Avoid overcharging and over-discharging, and avoid high temperatures and high-current discharge.
2. Regular maintenance: Perform a deep charge-discharge cycle on lead-acid batteries every 3 months; calibrate the BMS of lithium batteries every 1-2 months.
3. Proper storage: If not used for a long period, store the battery at around 50% and charge it monthly.
