The storage battery is the key factor affecting how far an e-bike can travel, and caring for and maintaining it well can greatly extend the life of the vehicle. Yet in daily use we often overlook these details, causing fatal damage to the battery.

The wear of the battery itself is gradual after all; the most serious damage to an e-bike battery comes from an improper environment or way of use. Let us now look at the causes of e-bike battery damage:

As a means of transport, an e-bike has its charging and discharging fully separated, and after a heavy high-current discharge it is not always recharged in time. Usually, if the lead sulfate formed after a lead-acid battery discharges is left without a charge for a long time, it gradually turns into sulfation crystals, causing irreparable damage to the battery.

As one of the convenient ways people get around daily, frequent charging and discharging is common for e-bikes. Some may charge several times a day, each for only a short while and before it is full, and a battery kept in an under-charged state for long will more easily lose capacity.

While working, a battery usually releases a steady current, but according to the load the current it delivers varies in depth. In general a battery has a maximum discharge current value, and exceeding it causes great harm. Starting, climbing, and carrying heavy loads are all situations where high-current discharge easily occurs.

Nowadays simple e-bike charging stations are often seen along the street: drop in a coin and it charges up quickly in a short time. But to shorten the charging time, high voltage is bound to be used, and excessive voltage or current causes heavy gassing and water loss in the battery.

Besides the main causes of battery damage above, poor battery quality, shedding plates, leaking electrolyte, a broken shell, and a snapped terminal are also reasons a battery fails. So when choosing a battery, it is best to pick a high-quality, well-reputed Xupai battery; a good battery helps you travel farther and keeps your e-bike safer and better protected.
