How often should the battery of an electric scooter be replaced？

First, let's look at it from the normal use of the battery. Due to the current mainstream electric vehicle battery for lead-acid battery and lithium battery, and lead-acid battery is generally the maximum charge and discharge times of 360 times, which means that under normal driving conditions, three days for a charge, electric vehicle battery can be used for about 3 years. The lithium-ion battery can be charged and discharged more than 500 times, and the electric car battery can last about four and a half years with one charge in three days. Therefore, from this point of view, whether it is lithium batteries or lead-acid batteries, under normal driving conditions, it only needs to be replaced once every three to five years.

Second, let's look at the overuse of batteries. Many users like to use their electric vehicles to haul goods or drive long distances, which makes them charge once a day, which means the battery life of the electric vehicles will be used up prematurely. Lead-acid batteries last about a year, and lithium-ion batteries last a year and a half at most. Of course, in this case, the battery of the electric vehicle may also be pulled, or even scrapped in advance. Therefore, from this point of view, excessive use of electric vehicles, one to one and a half years need to replace a new battery.

Finally, let's look at light battery use. Some users use the electric car less frequently, and they are likely to charge it only once a week, which will cause less damage to the battery. For lead-acid batteries, considering the aging of the battery, it can last about five years, while for lithium batteries, it can last about seven years. Therefore, at this level, both lithium and lead-acid batteries need to be replaced only once every five to seven years in light use. Of course, users need to pay attention to the fact that if they do not use electric vehicles for a long time, the battery may also be vulcanized to shorten the battery life, so at least maintain the frequency of charging a week.

In short, how long the electric car battery needs to be replaced is calculated according to the user's frequency of use. If the frequency is higher, the replacement cycle is shorter. Of course, if in daily life, develop good maintenance habits, can extend the battery replacement cycle to a certain extent.
