Recently, there are often electric bike users ask me such a question: the old electric bike battery does not run far, add water to restore the range, without a new battery? For this question, my answer is no, why say so? Here to give you a detailed explanation.

First of all, we need to know is that most of the mainstream electric bicycle batteries are maintenance-free batteries, which means that the battery does not need to be maintained during its service life. Generally speaking, the problem of old batteries not running far after a few years of use is basically an aging problem that can only be solved by replacing them with new ones. And even if some of the batteries in a short period of time, the problem of running not far, then in the warranty period can also be returned to the factory for repair. Therefore, from this point of view, the old electric bicycle battery is not to add water to repair.

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 lasts for a few months, or even a few weeks, and then the battery is not far from running completely. Here users need to pay attention to is that once the amount of water is not grasped, the battery may also be directly scrapped. Therefore, from this point of view, the old electric bicycle battery with water effect is not obvious, did not reach the expected level.

Finally, we need to know that if the old battery has been filled with drums, then adding water at this time will not have any effect. Therefore, from this point of view, for the old battery has been filled with drums, is not to add water, but only to take the new way.

So, some users may have this question: when do you need to add water to the old e-bike battery? Generally speaking, when the electric bicycle charging can't jump the light normally, the battery is really short of water, and this time it is possible to add water to repair.

In short, if the old e-bike battery is not filled with drum, then it is possible to add water appropriately, but it will not work to restore the effect as before. Therefore, after the problem of the old battery does not run far, generally do not choose to add water, but through the replacement of the new way to solve.

Of course, in daily life, to develop good habits of use, will be conducive to the battery life extension. For example, do not mix chargers, do not overload driving, do not overcharge, do not charge in direct sunlight, etc.. And the user to do the above points, will also maximize the protection of the battery, making it more durable.
