How long is the lifespan of electric scooter (e-scooter) batteries?
We can answer this question by considering the “charge-discharge cycles” of the battery. A “charge-discharge cycle” refers to the process an e-scooter battery undergoes from being fully charged to discharged and then recharged. After each cycle, the battery’s capacity diminishes, a phenomenon known as “memory effect.” Therefore, the more charge-discharge cycles, the shorter the lifespan of the e-scooter battery.
Generally, the lifespan varies depending on the type of battery:
- Lead-acid batteries typically experience a noticeable decline in their lifespan after 300-500 charge-discharge cycles, lasting approximately one and a half years.
- Lithium-ion batteries have a longer lifespan and typically start to degrade after about 800-1500 charge-discharge cycles, resulting in a usage lifespan of approximately 3 to 5 years.

This discrepancy is often attributed to users neglecting proper battery maintenance when using e-scooters. Ignoring battery maintenance can lead to battery damage even within the warranty period (typically 12 months for lead-acid batteries).

(1) Avoid frequent charge and discharge cycles, particularly in extreme temperature conditions.
(2) Select an appropriate charger and follow the manufacturer’s instructions for charging and discharging. Generally, it’s best to charge and discharge the battery in a suitable environment (around 15-25°C) with good ventilation, away from heat sources and water, and adhere to specified time limits. If any abnormalities such as overheating, smoking, or leakage are observed from the charger or battery, cease charging immediately and arrange for replacement or maintenance.
(3) Try to avoid using e-scooters in adverse environmental conditions like extreme heat, cold, humidity, muddy terrain, or rough roads. These conditions can accelerate battery aging and wear, and may even lead to risks such as short-circuits and explosions.
(4) Adjust the e-scooter’s speed and gears according to your weight and cargo load to prevent excessive acceleration or braking, reducing the battery’s stress.
(5) Follow proper charging and discharging procedures. When starting to charge, plug in the scooter first, then connect it to the 220V power source. When ending the charging process, disconnect the power source first, and then unplug the scooter. This method helps maintain stable battery voltage and extend its lifespan.
In summary, the lifespan of e-scooter batteries varies due to several factors, but by adhering to the practices mentioned above, you can effectively prolong the battery’s lifespan.
