Safety Instruction for Lithium-ion Batteries
-
Charging Current
For all rechargeable Lithium batteries (including Li-ion, IMR, and LiFePO4 batteries), we suggest not using current larger than 1C for charging. For small-capacity batteries, the charging current must be smaller than 1C. C=Capacity of a battery. For example, 1C in a 2600mAh rechargeable Lithium battery is 2.6A. 1C in a 3400mAh rechargeable Lithium battery is 3.4A. Excessively large charging current will lead to a great amount of heat, and consequently battery damage and explosion. -
Precautions
(1) DO NOT short circuit the battery in any way.
(2) DO NOT use a 3.7V/3.8V Lithium battery when its voltage is lower than
2.8V, otherwise it can be over-discharged, and/or prone to an explosion at next charging.
(3) We strongly recommend batteries with protective circuits. For batteries without protective circuits (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. -
Long-term Storage
The best storage voltage for 3.7V/3.8V 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.

Operating Instructions
Connect to the power source: Connect the UI1 to an external power source (a USB adapter, a computer or other USB charging devices) via the USB charging cable. After connecting to the power source, the indicators will glow for approx. 1 second before they go out.
Insert the battery: The UI1 features 1 charging slot available for charging variously sized rechargeable Li-ion batteries. Please insert the battery of supported types into the slot according to the polarity mark on the slot. When the battery is inserted with the polarities reversed, the battery will not be charged, and all 3 indicators will flash to indicate an error.
Charging indication: When the charging status is normal, the indicators will flash to indicate the battery level. When the battery is fully charged, all 3 indicators will glow steadily. When the charging status is abnormal (e.g. the battery is short-circuited), all 3 indicators will flash to indicate an error.
Charging current: The UI1 is available for low current charging below 2.9V. When a battery with a voltage below 2.9V is inserted, the charger will automatically access the Low Current Charging Mode with a charging current of 100mA. When a battery with a voltage over 2.9V is inserted, it will access the Standard Model with a max charging current of 1000mA.
Over-Discharged Li-ion Battery Activation
The UI1 is capable of activating over-discharged Li-ion batteries with a
protective circuit. After battery installation, UI1 will test and activate the
battery before charging. When a battery is detected as damaged, the indicators
will not be turned on. In this case, please cease the charging process
immediately.
Note: Please DO NOT charge unprotected 0V over-discharged Li-ion
batteries, or it will result in fire or even battery explosions.
Thermal Protection Function
When the charger is overheated due to the high temperature of the working environment, the UI1 will automatically regulate the charging current to protect the charger and the battery.
Anti-short Circuiting and Reverse Polarity Protection
If the battery is inserted with polar reversed or short-circuited, all 3
indicators will flash to indicate an error.
Precautions
- The charger is restricted to charging Li-ion and IMR rechargeable batteries only. DO NOT use the charger with other types of batteries as this could result in battery explosion, cracking or leaking, causing property damage and/or personal injury.
- Moderate heat from this product is to be expected during the charging process, which is normal.
- Ambient Temperature of Usage: -10~40℃ (14~104℉); Temperature of Storage: -20~60℃ (-4~140℉)
- Carefully read all labels on the device to ensure batteries are installed correctly.
- Please connect this charger to power supplies with the input voltage stated in the specifications of the user manual. If the input voltage is too low or too high, it may lead to malfunctions or even a fire.
- DO NOT charge batteries if there is any sign of faulty or short circuit.
- The charger is designed for adults. Use of the charger by kids under age must be under supervision. The operation, using, or cleaning of the charger may NOT be done by kids aged 8 years or younger.
- DO NOT leave the product unattended while it is connected to a power supply. Unplug the product at any sign of malfunction.
- DO NOT attempt to charge primary cells such as Zinc-Carbon, Lithium, CR123A, CR2, or any other unsupported chemistry due to the risk of explosion and fire.
- DO NOT charge a damaged IMR battery as doing so may lead to charger short-circuit or even explosion.
- DO NOT charge or discharge any battery having evidence of leakage, expansion/swelling, damaged outer wrapper or case, color-change or distortion.
- Use the original adapter and cord for the power supply. To reduce the risk of damage to the power cord, ALWAYS pull by the connector rather than the cord. DO NOT operate the charger if it appears damaged in any way.
- DO NOT store or use the product in an environment where the temperature is extremely high/low or changes rapidly, or in a confined area with a high temperature.
- Store the device in ventilated areas. DO NOT use the device in moist environment and keep away from any combustible materials.
- Avoid any shock or impact on the device.
- DO NOT place any conductive or metal object in the device to avoid short-circuiting and explosions.
- DO NOT overcharge or over-discharge the batteries. Please recharge the battery as soon as the power runs out.
- Unplug the device and remove all batteries when it is not in use.
- DO NOT disassemble or modify the device as doing so will render the product warranty invalid. Please refer to the warranty section in the manual for complete warranty information.
