Recently, users of electric motorcycles often ask me such a question: If the battery of an old electric motorcycle does not run far, the battery life can be restored by adding water, without changing the battery? My answer to this question is no. Why do you say that? Let's give you a detailed explanation below.
First of all, we need to know that most mainstream electric motorcycle batteries are maintenance-free batteries, which means that the batteries do not need to be maintained during their service life. Generally speaking, the problem that the old battery does not run far after a few years of use is basically an aging problem, which can only be solved by replacing it with a new one. Even if part of the battery does not run far in a short period of time, it can be returned to the factory for repair during the warranty period. Therefore, from this point of view, the old battery does not need to be repaired with water.
Secondly, let's look at the effect of adding water to the old battery. Usually the old battery will recover 50%-70% performance after adding water, but this effect is short-lived, generally only lasting a short period of a few months, or even a few weeks, and then the battery will not run far. What users need to pay attention to here is that once the amount of water added is uncertain, the battery may be directly scrapped. Therefore, from this point of view, the effect of adding water to the old battery is not obvious, and it does not reach the expected level.
Finally, what we need to know is that if the old battery has been charged, adding water at this time will not have any effect. Therefore, from this point of view, it is not possible to add water to an old battery that has been charged, but can only be replaced with a new one.
So, some users may have this question: When do old electric motorcycle batteries need to be filled with water? Generally speaking, when the electric motorcycle cannot be charged normally, the battery is really short of water. At this time, it can be repaired by adding water.
In short, if the old battery is not charged, then water can be added appropriately, but the original effect will not be restored. Therefore, after the old battery does not run far, it is generally not chosen to add water, but to be solved by replacing it with a new one.
Of course, in daily life, developing good usage habits will help extend battery life. For example, don't mix chargers, don't drive with overload, don't charge and over discharge, don't charge under direct sunlight, etc. The user will do the above points to protect the battery to the greatest extent and make it more durable.
