Protecting Your Battery

Maintain the battery for a longer ride.

Why do you need to maintain the battery?

The NIU battery pack is made up of Panasonic lithium-ion battery cells to power your vehicle. Compared with traditional lead-acid batteries, lithium batteries provide five times more energy density and are significantly lighter. However, the use and storage of lithium batteries does require special attention.

Just like laptops, mobile phones, and other devices that use rechargeable lithium-ion batteries, NIU scooter batteries should be looked after in order to preserve their lifespan. By neglecting or failing to look after the battery, the battery pack may suffer irreversible damage, which can impair the product’s overall performance.

Battery Care Tips

For long-term storage, remove the battery from the vehicle. Keep the battery’s level at around 50%.

If you do not use your vehicle or charge the battery for over 15 days, there are two factors you should consider to maintain the battery’s health - ① Room temperature ② Power level before storage. We recommend the following:

1. Do not charge the battery in an environment below 0 °C. Store the battery in a cool dry place between 0 °C and 40 °C.

2. If the power level is less than 20%, please charge it. Be sure to take the battery pack out of the vehicle and store it separately after fully charged. A full charge will protect the battery pack for 3 - 5 months. Please check the battery regularly.

3. If the battery pack is exhausted, the Battery Management System (BMS) will enter a ‘sleep state,’ so the charger will not be able to properly charge the battery pack. If this occurs, please do not disassemble the battery pack yourself, and instead, contact your nearest service station for repairs.

Update the BMS to the latest version.
Go to your nearest NIU service station.

In order to enhance your NIU electric experience, we continue to conduct more in-depth research and experiments on the NIU BMS. When a new version of the BMS is available, we will prompt you to go to your nearest NIU certified service station. At the station, our trained engineers can help you upgrade your BMS. Upgrading to the latest version will help your battery become more efficient and last longer.

Use caution and store your battery safely.

Some areas are hazardous and unsafe for battery storage. These include heat sources, open flames, flammable & explosive gases, and liquids. Batteries that are exposed to these hazardous environments may cause leakage, emit smoke, catch fire and even explode. Dropping the battery may result in permanent damage. Store the battery in an area with no risk of falling. Please also avoid exposing the battery to water, beverages, corrosive liquids, and metal foreign objects.

Keep away from extreme temperatures.

The NIU battery’s performance is optimized between -10 ° C and 45 ° C. However, using the battery in temperatures outside of this range may lead to long-term damage. The temperature of the charging environment should also be taken into account. The ideal charging temperature will be between 0 ° C and 35 ° C. If the battery has not been used for over 15 days, please store the battery in an environment with a temperature range between 0 °C and 40 °C to avoid irreversible damage.

NIU Battery Riding Temperature Range

Please use the battery in an area between -10 ° C and 45 ° C.

NIU Battery Storage Temperature Range

Please store the battery in an area between 0 °C and 40 °C.

NIU Battery Charging Temperature Range

Please charge the battery in an area between 0 °C and 35 °C.

Self-check:

When the battery has not been used for a long period of time, put the battery back into the battery compartment. If the scooter’s dashboard indicates that the power is 0 %, but the charger’s green light signals a full charge, please unplug the battery immediately. We will help you to contact the nearest NIU service network or professional engineer to solve the problem as soon as possible.
