Safety Instruction for Lithium-ion Batteries

1. Charging Voltage
   Lithium-ion (Li-ion) batteries have strict requirements on voltage control. Charging Li-ion batteries with electric voltage beyond safety standards can lead to battery damage and explosion.

(1) 4.2V Li-ion Batteries/1MR Batteries
4.2V Li-lon batteries are the most common rechargeable Lithium batteries. The skins of these batteries are often marked with 3.6V/3.N signs. If our chargers judge that an inserted battery is a Li-on battery, the battery will be automatically Charged In a 4.2V standard charging mode. You do not need extra voltage settings for these types of batteries.
(2)4.3W Li.lon Batteries
4.35V Li-ion batteries are comparatively rare. It usually has a 3.7V mark on its skin. Normally its seller will inform its buyer that it needs to be charged with 4.35V power. When charging this type of battery, please manually set the charging voltage to 4.35V, otherwise, the charger will charge at 4.2V by default, and cannot provide adequate charging voltage.
(3) 3.7V LiFePO4 Batteries
3.7V LiFePO4 batteries have LiFePO4 and/or 3.2V marks on the skin. Be careful with this type of battery. Without manual setting, our chargers will charge this type of batteries with 4.2V voltage and will damage or even explode the battery with excessive charging voltage. You need to manually set the charging voltage to 3.7V for safe charging.
2. Charging Current
For all rechargeable Lithium batteries (Including IMR and LIFePO4 batteries), we suggest not using a current larger than 1C* for charging. For small capacity batteries. the charging current must be smaller than 1C. t•Capacity of a battery. For example, 1C in a 2600mAh rechargeable Lithium battery Is 2.6A. 1C in a 3400nukh rechargeable Lithium battery Is 3.4A. Excessively large charging current will lead to great amount of heat, and consequently battery damage and explosion.
Warning: Our chargers automatically judge and select charging current by the batteries’ length. For some long but small capacity batteries (i.e. 12650. 13650. 14650. 16650), please manually set the appropriate charging current (smaller than 1C).
3. Precautions

1. Do not short circuit the battery in any way.
2. Do not use a 4.2V/4.3V Lithium battery when its voltage is lower than 2.V. otherwise it can be over-discharged, and/or prone to an explosion at the next charging.
3. We strongly recommend batteries with a protective circuit. For batteries without protective circuit (such as IMR batteries), please stay alert for over-discharge and short circuits.
4. Do not discharge a battery with a discharging current larger than its maximum rated current.

4. Long-term Storage
The best storage voltage for 4.2V/4.35V rechargeable Lithium batteries is 3.7V. Voltage too low or too high can damage your battery during storage. You can discharge a battery to 3.7V. or charge it to 3.7V in a charger before you keep it in long-term storage.
