1、 What factors are related to the battery life of electric bicycles?

The lifespan of electric bicycles is related to the type of battery, with sodium batteries having the longest lifespan, reaching 3000-6000 cycles, lithium batteries at 800-1500 cycles, lead-acid batteries at around 500 cycles, and fully charged and discharged batteries counted as one cycle.
Secondly, the capacity of the battery is also related. The larger the capacity of the battery, the longer its range, and the longer the full charge and discharge time. As long as it is not frequently deeply charged and discharged, the battery is not easily damaged. But for those with small capacity, they may need to be deeply charged and discharged once every two days, and the battery will decay faster!
The third one is related to the usage scenario. If it is daily commuting, shopping, or non violent driving, the battery is less likely to be damaged and can be used for a longer period of time. But for someone like a delivery guy who rides over 100 kilometers a day, the battery won’t be used.
Finally, it is related to battery charging and discharging. If it is a shallow dry charge and the battery is always in a fully charged state, then the battery health is high and the battery life is long. If it is long-term non charging or long-term use of fast charging. The lifespan of the battery will decrease.

2、 What is the normal lifespan of a battery?

Small capacity lead-acid batteries, such as 48V12ah, 48V14ah, and 48V16ah, typically require replacement after 1-3 years of use. Even if it is not used frequently, the battery will still break due to its self discharge effect. Large capacity lead-acid batteries with 48V20ah, 60V20ah, and 72V20ah can last for 2-4 years. A super large capacity battery of 32ah or above can last for 5-7 years!
The lifespan of lithium batteries is relatively long, with a small capacity of 12 hours lasting 3-5 years and a large capacity lasting 5-10 years. Among them, ternary lithium is used less frequently, while lithium iron phosphate is used the longest, up to 8 years or more!
Under the current technological conditions, the service life of sodium batteries is similar to that of lithium iron phosphate, approximately 5-10 years. After the maturity of future technology, it may take more than 20 years!
Summary:
To last a long time with an electric bicycle battery, on the one hand, choose a large capacity battery as much as possible, which is actually to keep the battery in a charged state. Finally, do not drive violently and park the car in a cool place for charging, which is beneficial for the long-term use of the battery
