To prevent personal injury or property damage, the following must be strictly observed and handled.
The degree of possible injury and damage owing to intended abuse, incorrect use or mishandling is described by the three levels of instructions (Danger! / Warning! / Caution! ) below.
Danger!
Never use a DC power supply to charge the Li-ion battery pack! A DC power supply may overly charge the Li-ion battery pack, which may cause serious safety issues.
Ensure the correct polarity when connecting a Li-ion battery pack to a CC/CV (Constant Current / Constant Voltage) charger.
Never charge a Li-ion battery pack under inverse polarity!
Never leave a Li-ion battery pack unattended while connecting to a charger!
Never drop a Li-ion battery pack into water!
Never incinerate a Li-ion battery pack! Toxic material may burst or release to harm eyes and skins.
Never leave a Li-ion battery pack under the blazing sun or inside a car with closing windows! The long time overheated Li-ion battery pack may cause smoke or flame.
Never disassemble or shred a Li-ion battery pack! It may cause unexpected venting or explosion!
Never charge or discharge a Li-ion battery pack excessively!
Never short-circuit a Li-ion battery pack if you are not sure if the pack is made with a protection circuit module (PCM or PCB)! Handle with care when a Li-ion battery pack is made with flying leads.
Never shock a Li-ion battery pack with a heavy mechanical force.
Warning!
Never connect a new Li-ion battery pack in series with another old battery or battery pack, especially when the battery chemistry is different.
Never touch or handle a Li-ion battery pack if it is unusually hot, whether through continuous large current discharge or external heat.
Never remove or cut through the shrinking wrap insulation of a Li-ion battery pack.
Never over-discharge a Li-ion battery pack if its power output to drive a dedicated load is obviously failing.
Stop using a Li-ion battery pack if venting, excessive temperature or noise is detected.
Keep a Li-ion battery pack away from babies or children. Seeking a doctor treatment immediately if swallowed.
Do not allow the bursting liquid to contact eyes or skins in an event of venting! Wash the affected areas with large amount of water and then seek medical advice immediately.
Caution!
Use a dedicated charger to charge your Li-ion battery pack. If no dedicated charger is available, a CC/CV (Constant Current / Constant Voltage) charger with proper voltage range shall be properly selected.
When using a Li-ion battery pack from a long term storage, charge the pack fully at 0.2C rate before using it. The pack can be fully activated after 2 ~ 3 deep cycles of charge and discharge.
Li-ion battery pack is not required to be fully discharged. You may charge your Li-ion battery at any time. After you fully activate your pack, avoid the deep cycles to lengthen the life of your Li-ion battery pack. However, two deep cycles of activation are suggested to apply every 3 months.
If the battery pack is getting hot after discharge, allow it to cool before charging it.
Unplug a Li-ion battery pack by holding its connector, in stead of pulling its wire.
Keep your Li-ion battery pack at ambient temperature around -10 ~ 25 degree C and maintain its SOC (State of Charge) about 40% ~ 50% for long term inventory.
When not using a Li-ion battery pack, disconnect it from the device.
Disposed Li-ion battery pack should be treated by officially authorized unit.
Battery packs with different chemistry should be separated when disposing them.
