Similarly, frequent shallow discharging (only partially using the battery’s capacity) and charging can also negatively impact the battery. Striking a balance by avoiding extreme ends and charging your battery when it reaches around 20-30% capacity can help extend its lifespan.
Charging Cycles
The number of charging cycles your e-bike battery goes through can also impact its life expectancy. A charging cycle refers to the process of consuming the battery’s full capacity and recharging it back to full. Li-ion batteries, for example, typically have a cycle life of 500-1000 cycles. The more charging cycles your battery goes through, the more it will gradually lose its capacity. Being mindful of your charging cycles and prolonging the intervals between them can help increase the overall lifespan of your battery.
Overcharging and Undercharging
Overcharging can cause irreversible damage to e-bike batteries, leading to reduced capacity and shorter overall lifespan. It is crucial to avoid leaving your battery connected to the charger for extended periods once it reaches full capacity. Similarly, undercharging your battery by not reaching its full capacity before disconnecting it from the charger can also impact its life expectancy. Following the manufacturer’s charging instructions and disconnecting the charger once the battery is fully charged is essential for prolonging battery life.
