Electric vehicles are loved by consumers for being energy-saving, eco-friendly and convenient, but the electric vehicle battery can be a hassle. How often should you replace your e-bike battery? How often is best?

In fact, an electric vehicle battery does not have to be replaced as soon as a problem appears. Unless there are issues such as a short circuit, swelling, broken pole plates, or a damaged casing, it generally does not need to be replaced; it can continue to be used after being repaired at a specialty store. Battery swelling is caused by overcharging. A swollen battery is already deformed, and consumers can feel it by touching it with their hands. A damaged casing can also be seen with the eye. Broken pole plates and short circuits, however, can only be seen by opening the battery. If a repairer proposes replacement on these two grounds, consumers can ask the repairer to open the battery and inspect it on the spot.

Furthermore, if you really need to replace the battery, be sure to observe whether it is new or old. To judge this, consumers can check whether the terminals show traces of soldering or previous use, and whether the casing is clean. A refurbished old battery will always leave some trace of its past use.

In addition, when getting a new battery, first check the packaging of the new battery and, if possible, inspect it yourself before it is opened. Before sending the e-bike for repair, be sure to note the model numbers of the battery, motor, and related parts, and always check them against the records when the repair is finished.

If a battery manufacturer really refurbishes a battery, it must replace all the lead plates after opening the battery case, and the performance and price will be little different from a new battery. However, many roadside shops, to maximize profit, usually just add some repair fluid and call it a refurbishment, so the quality of such a refurbished battery can be imagined. These batteries generally have a very short lifespan and cannot guarantee usage time.

The above are some tips on replacing batteries. We hope they are helpful.
