What is the general lifespan of a scooter motorcycle battery?

The lifespan of a scooter motorcycle battery is approximately 4 years. Motorcycle batteries are generally 12V, such as 12V5AH, 12V7AH, 12V9AH, etc. The motorcycle starter motor is a DC motor, which uses direct current (i.e., the battery) to start, with a starting voltage of no less than 12V. Scooters are basically automatic clutch CVT (continuously variable transmission), similar to Mullan-style electric vehicles, with no gear design. Once started, you only need to twist the throttle to move, and releasing the throttle will automatically gradually decelerate until stopping. Additionally, the wheels of scooters are smaller than those of other vehicles, and the transmission is mostly belt-driven. The term 'scooter' refers to the wide footboard between the seat and the handlebars, allowing riders to comfortably place their feet on it.
My scooter's battery died after just two and a half years of use, making morning starts particularly difficult. The mechanic said scooter batteries typically last only two to three years, especially prone to failure in winter. He taught me several methods to extend battery life: ride for at least 20 minutes weekly to recharge, disconnect the battery if not riding for extended periods; avoid using headlights or listening to music with the engine off; and beware that aftermarket GPS trackers are major power drainers. Now I regularly check battery terminals for white crystalline deposits, which can cause poor contact. Last winter, I proactively replaced the battery before the cold set in, and this year it starts reliably even at -10°C.
In our repair shop, we often see scooter batteries failing prematurely, and the key lies in usage habits. Short-distance urban commuting is the most damaging to batteries, as the power consumed during each start-up isn't sufficiently recharged before reaching the destination. Factory batteries typically last about three years, but frequent power depletion can kill them in just one year. Here are three self-check tips: Be cautious if the cold-start voltage is below 12.5 volts; replace the battery immediately if the inspection window turns black; when starting the engine, turn on the headlights—if they dim drastically, it indicates power depletion. Motorcycles with high-power audio modifications should pay special attention to voltage. I've seen cases where a rider's modified audio system burned out the battery in just two months.
