Proper Use and Handling of Lithium Ion Battery

This post has been prepared to describe the appropriate cautions and prohibitions, which the customer should take or employ when the customer uses and handles the lithium ion battery to be manufactured and supplied by Onex Limited, in order to obtain optimum performance and safety.

1. Charging

1.1 Charging current

Charging current should be less than maximum charge current specified in the product specification.

1.2  Charging voltage

Charging should be done by voltage less than that specified in the product specification.

1.3  Charging time

Continuous charging under specified voltage does not cause any loss of performance characteristics. However, the charge timer is recommended to be installed from a safety consideration, which shuts off further charging at time specified in the product specification.

1.4  Charging temperature

The battery should be charged within a range of specified temperatures in the specification.

1.5  Reverse charging

The battery should be connected, confirming that its poles are correctly aligned. Inverse charging should be strictly prohibited. If the battery is connected improperly, it may be damaged.

2. Discharging

 2.1  Discharging

The battery shall be discharged continuously at less than maximum discharge current specified in the product specification. In case of the higher discharge current should be set, it shall be discussed together with Onex limited.

2.2  Discharging temperature

2.2.1  The batteryshould be discharged within a range of temperatures specified in the product specification.

2.2.2  Otherwise, it may cause loss of characteristics.

2.3  Over-discharging

2.3.1  The system should be equipped with a device to prevent further discharging exceeding discharging cut-off voltage specified in the product specification.

2.3.2  Over-discharging may cause loss of performance, characteristics of battery function.

2.3.3  Over-discharging may occur by self-discharge if the battery is left for a very long time without any use.

2.3.4  The charger should be equipped with a device to detect batteryvoltage and to determine recharging procedures.

3. Storage

3.1  Storage conditions

3.1.1  The batteryshould be stored within a range of temperatures specified in the product specification.

3.1.2  Otherwise, it may cause loss of performance characteristics, leakage and / or rust.

 

3.2 Long-term storage

3.2.1   The batteryshould be used within a short period after charging because long-term storage may cause loss of capacity by self-discharging.

3.2.2  If long-term storage is necessary, the batteryshould be stored at lower voltage within a range specified in the product specification, because storage with higher voltage may cause more loss of performance characteristics.

3.2.3  Store the battery at 0 ~ 23℃, low humidity (below 65%), no dust and no corrosive gas atmosphere.

4. Cycle life

4.1  Cycle life performance

4.1.1   The batterycan be charged / discharged repeatedly up to times specified in the produce specification with a certain level of capacity also specified in the product specification.

4.1.2   Cycle life may be determined by conditions of charging, discharging, operating temperature and/or storage.

5. Battery Pack Assembly

5.1  Prohibition of usage of damaged battery

5.1.1   The batteryshould be inspected visually before battery assembly.

5.1.2  The batteryshould not be used if sleeve-damage, can-distortion and / or electrolyte-smell is detected.

5.2   Terminals handling

5.2.1   Excessive force on the negative terminal should be avoided when external strip terminal is welled.

5.3   Transportation

5.3.1   If the batteryis necessary to be transported to such as the battery manufacturer, careful precautions should be taken to avoid damage of battery.

6. Others

6.1  Disassembly

6.1.1   The batteryshould not be dismantled from the battery pack.

6.1.2  Internal short-circuit caused by disassembly may lead to heat generation and / or venting.

6.1.3  When the electrolyte is coming in contact with the skin or eyes, wash immediately with fresh water and seek medical advice.

6.2   Short-circuiting

6.2.1   Short-circuit results in very high current which leads to heat generation.

6.2.2   An appropriate circuitry should be employed to protect accidental short-circuiting.

6.3   Incineration

6.3.1   Incinerating and disposing of the batteryin fire are strictly prohibited, because it may cause rupture and explosion.

6.4   Immersion

6.4.1    Soaking the batteryin water is strictly prohibited, because it may cause corrosion and leakage of components to be damaged to functions.

6.5   Mixing use

6.5.1    Different types of battery, or same types but different batterymanufacturer’s shall not be used, which may lead to battery imbalance, battery rupture or damage to system due to the different characteristics of battery.

6.5.2    Do not mix use the batterys from different batches / ranks even they are the same batterytypes from the same manufacturer.

6.6   Battery disposal

6.6.1    Although the batterycontains no environmentally hazardous component, such as lead or cadmium. the battery should be disposed according to the local regulations when it is disposed.

6.6.2     The batteryshould be disposed with a discharged state to avoid heat generation by an inadvertent short-circuit.

6.7   Caution

6.7.1    The Battery used in this device may present a risk of fire or chemical burn if mistreated.

6.7.2    Do not disassemble, expose to heat above 100℃ or incinerate it. 

6.7.3    Replace battery with Onex Limited battery only. 

6.7.4    Use of another battery may present a risk of fire or explosion.

6.7.5    Dispose of used battery promptly.

6.7.6    Keep away from children. 

6.7.7    Do not disassemble and do not dispose of in fire.
