Please read this manual thoroughly before operating the device to ensure proper use and maximize battery lifespan.

Important Safety Information

• Use only with compatible rechargeable batteries. Do not attempt to charge non-rechargeable batteries.
• Ensure correct battery polarity (+/-) when inserting batteries into the charging slots.
• Operate the charger in a well-ventilated area, away from direct sunlight, high temperatures, and humidity.
• Do not disassemble or modify the charger. Refer all servicing to qualified personnel.
• Keep the charger and batteries out of reach of children and pets.
• Unplug the charger from the power source when not in use or before cleaning.
• The charger features microprocessor control to prevent overcharging and overheating. However, always monitor the charging process.

Key Features:

• Microprocessor Control: Ensures safe and optimized charging, preventing overcharge and overheating.
• Independent Charging Channels: Each of the four slots operates independently, allowing mixed battery types and sizes.
• Large LCD Display: Provides detailed information for each channel, including voltage, current, time, and charged capacity.
• Multiple Operating Modes: Charge, Discharge, Refresh, Capacity Test, and Quick Test (IR).
• Wide Battery Compatibility: Supports Ni-MH (AA, AAA, C, D) and Li-ion (18650, 14500, 16340, 20700, 21700, etc.).
• 0V Battery Reactivation: Capable of reactivating deeply discharged 0V Li-ion batteries.
• USB Output: 5V DC, 1000mA for charging external devices.

Setup and First Use

1. Unpack the Charger: Carefully remove the UC-4000 charger and its accessories from the packaging.
2. Connect Power: Connect the provided AC power adapter to the DC input port on the back of the charger. Plug the adapter into a standard wall outlet (100V-240V). The LCD screen will illuminate.
3. Insert Batteries: Insert one or more compatible rechargeable batteries into the charging slots. Ensure correct polarity (+ and - terminals match the markings on the charger). The charger will automatically detect the battery type (Ni-MH or Li-ion) and display initial information.
4. Select Mode (Optional): By default, the charger will begin charging. To select a different operating mode (Discharge, Refresh, Test), press the corresponding button for the desired slot within a few seconds of inserting the battery.

Operating Modes

The UC-4000 offers five distinct operating modes to manage your batteries effectively. Each mode can be selected independently for each charging slot.

1. Charge Mode

This is the default mode. The charger will automatically detect the battery type and begin charging at a suitable current. You can manually adjust the charging current (200-400-600-800-1000 mA) for Li-ion batteries (up to 1A per slot for 4 batteries, or 500mA if preferred) and Ni-MH batteries. The LCD will display the current, voltage, and charged capacity.

2. Discharge Mode

In this mode, the charger discharges the battery before recharging it. This can help reduce the memory effect in Ni-MH batteries. Discharge current can be set (100-200-300-400-500 mA).

3. Refresh Mode

This mode cycles the battery through multiple charge-discharge cycles to optimize its capacity and potentially restore older batteries. This process can take several hours or even days depending on the battery condition.

4. Capacity Test Mode

The charger fully charges the battery, then discharges it to measure its actual capacity, and finally recharges it. This provides an accurate reading of the battery's real capacity.

5. Quick Test (IR) Mode

This mode quickly measures the internal resistance (IR) of the battery. A lower internal resistance generally indicates a healthier battery. This is a rapid diagnostic tool.

Battery Compatibility

The everActive UC-4000 is a highly versatile charger, compatible with a wide range of rechargeable battery sizes and chemistries. It supports both Ni-MH and Li-ion battery types.

Supported Battery Types:

• Ni-MH / Ni-CD: AA (R6), AAA (R03), C (R14), D (R20) - Note: C and D cells require optional adapters and only 1-2 cells can be charged simultaneously due to size.
• Li-ion / LiFePO4: 10440, 14500, 16340 (RCR123), 17500, 17670, 18350, 18500, 18650, 20700, 21700, 22650, 26500, 26650.

The charger's intelligent system automatically identifies the battery chemistry and applies the appropriate charging algorithm.

Maintenance

• Cleaning: Disconnect the charger from the power source before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
• Storage: Store the charger in a cool, dry place when not in use. Avoid extreme temperatures and humidity.
• Contact Points: Periodically check the charging contacts for any dirt or corrosion. Clean gently with a cotton swab if necessary.

Troubleshooting

Charger not turning on:

Ensure the power adapter is securely connected to both the charger and a working wall outlet. Check if the outlet has power.

Battery not charging:

Verify that the battery is inserted with correct polarity. Ensure the battery is a compatible rechargeable type. Try cleaning the battery contacts and charger contacts. If the battery is severely over-discharged (0V), the charger has a reactivation function, but some batteries may be beyond recovery.

Incorrect capacity reading during test:

Ensure the battery has undergone a full charge-discharge-charge cycle (Refresh or Capacity Test mode) for accurate measurement. Battery age and condition can affect actual capacity.

Charger or batteries feel warm:

It is normal for the charger and batteries to become slightly warm during operation. If they become excessively hot, immediately disconnect the power and remove the batteries. Ensure adequate ventilation around the charger.

USB output not working when unplugged from AC:

The USB power bank function of the UC-4000 requires the charger to be connected to its AC power adapter. It does not operate as a portable power bank using only inserted batteries.
