The service life of Citycoco electric scooter batteries primarily depends on the battery type, usage habits, maintenance methods, and environmental conditions, with lithium-ion batteries (the most common type for Citycoco) having a typical service life of 3 to 5 years or approximately 1000 charge cycles under normal use. However, high-quality lithium iron phosphate (LiFePO4) batteries, such as those produced by Keheng, can have a much longer service life, with cycle life reaching 3000-6000 cycles at 50% depth of discharge (DOD) and a design life of up to 10 years. The cycle life refers to the number of times the battery can be fully charged and discharged before its capacity drops to 80% of the original capacity—after this point, the battery’s performance will gradually decline, and it may need to be replaced.

Several factors can significantly affect the service life of Citycoco batteries. Proper maintenance is crucial: avoiding deep discharge (letting the battery run out completely) and overcharging can extend the battery’s life. Deep discharge can damage the internal structure of the battery cells, leading to irreversible capacity loss, while overcharging can cause electrolyte decomposition and overheating, accelerating battery aging. Environmental conditions also play a role: storing the battery in a moderate temperature environment (between 10℃ and 30℃) avoids damage from extreme cold or heat. Storing the battery in a fully discharged state for a long time can cause it to “starve” and become unusable, while storing it in a fully charged state for an extended period can accelerate capacity decay. Additionally, using the original charger and avoiding low-quality chargers can prevent damage to the battery’s internal management system (BMS), which is responsible for protecting the battery from overcharge, overcurrent, and overheating. With proper care and maintenance, a high-quality Citycoco battery can exceed its expected service life, providing reliable power for a longer period.
