To prevent potential issues such as leakage or overheating, please adhere to the following precautions:
● Do not immerse the battery in water or seawater. When not in use, store it in a cool, dry place.
● Avoid exposing the battery to high temperatures (e.g., near fire or heaters). High temperatures may cause overheating, fire, performance degradation, or reduced service life.
● Do not reverse the positive and negative terminals.
● Do not reverse polarity during charging.
● Never connect the battery electrodes directly to an electrical outlet.
● Avoid short-circuiting the battery, as it may cause severe damage.
● Do not transport or store the battery with metal objects such as hairpins, necklaces, etc.
● Do not strike, step on, throw, drop, or subject the battery to strong impacts.
● Do not solder directly onto the battery or puncture it with nails or other sharp objects.
● Avoid using the battery in areas with strong static electricity or magnetic fields, which may damage safety components and create potential hazards.
● Use only a designated charger specified for this battery.
● Recharge the battery within 12 hours after use.
● Ensure the charging current does not exceed the maximum specified in the product specifications. Higher current may damage the battery.
● Ensure the discharging current does not exceed the maximum specified in the product specifications. Higher current may damage the battery.
● If the battery will not be used for an extended period, periodically recharge it (every 2 months) to maintain voltage between 15.6V and 16V to prevent over-discharge due to self-discharge. Over-discharging may result in permanent loss of performance and functionality. For battery packs with communication function, recharge once per month.
● If battery leakage occurs and electrolyte enters the eyes, do not rub them. Immediately rinse with clean water and seek medical attention to prevent eye injury.
● If the battery emits an unusual odor, overheats, changes color, deforms, or appears abnormal during use, charging, or storage, stop use immediately, remove it from the device, and discontinue charging.
● If the battery terminals are dirty or oxidized, clean them with a dry cloth before use to ensure proper connection and performance.
● When disposing of the battery, insulate the terminals with tape.
● Shallow charging and discharging (e.g., discharging up to 80% of nominal capacity) can help extend the cycle life of the lithium-ion battery.
1. Battery Inspection
● Upon receiving the battery, carefully inspect the packaging and the battery itself. Ensure there are no signs of electric shock, leakage, or physical damage.
● If any damage or leakage is found, examine the battery box and accessories, and contact us immediately.
● Verify that the output connector is correct. Use a multimeter to check whether the positive and negative voltages are within the normal specified range.
2. Precautions
● Avoid smoking or exposure to open flames during installation to prevent short circuits, equipment damage, or personal injury.
● Install the battery in a well-ventilated area away from direct sunlight and potential flooding.
● When securing battery terminals, avoid applying excessive force to prevent damage.
● Clean battery components only with a dry cloth. Do not use oil or volatile organic solvents, as these may damage the battery compartment.
● Always ensure correct polarity when connecting positive (+) and negative (-) terminals. Incorrect connection may cause fire, battery damage, or equipment failure.
3. Battery Installation
● Clean the installation area to ensure it is free of dust and metal debris.
● Position the battery in the designated location.
● Securely connect the terminals between the device and the battery.
● After connection, verify that all connections are secure, polarity is correct, and no dust or debris is present.
1. To ensure longer cycle life, please recharge the battery promptly when it is running low. Allowing the battery to remain in a depleted state for extended periods may reduce its overall lifespan.
2. The battery should be installed in a dry, clean, and well-ventilated area. Keep flammable materials away from the battery during charging and discharging.
3. Operating Conditions:
● Temperature: –20°C to +60°C
● Humidity: ≤85% RH
● If temperature exceeds 45°C, ensure adequate ventilation.
● If humidity exceeds 85%, take appropriate protective measures.
4. Charging Conditions:
● Temperature: 0°C to +45°C
● Humidity: ≤85% RH
● If humidity exceeds 85%, ensure proper protection is in place.
5. Storage Conditions:
● Temperature: 0°C to 45°C (recommended: 15°C–25°C in a dry environment)
Note: ● Battery capacity may vary with temperature—this is normal.
● Do not clean the battery or compartment with organic solvents.
● In case of a battery fire, use a dry powder fire extinguisher or sand to extinguish.
1. Low Voltage After Full Charge
● Cause: Extended storage without proper maintenance charging.
● Solution: Recharge the battery to restore normal voltage.
2. Physical Damage or Electrolyte Odor
● Cause: Severe impact, casing damage, or noticeable electrolyte smell.
● Solution:
● Physical damage generally falls outside standard maintenance. If repair is attempted:
● Check output cables and connectors for damage—replace if necessary.
● If a strong acidic odor is detected, the battery may be leaking.
● Measure voltage of each series. If one shows significantly lower voltage, replace that series.
3. Insufficient Capacity
● Solution: Perform 3–5 full charge/discharge cycles to restore capacity.
4. Zero or Low Voltage After Charging (Charger Indicates Full)
● Cause A: Disconnected circuit
● Solution: Inspect wiring for damage, broken solder joints, or fractured nickel strips. Repair or replace as needed.
● Cause B: PCB malfunction
● Solution:
● Ensure all cables are securely connected to the protection board.
● Check for soldering defects.
● Measure voltage between B+/B- and P+/P- terminals. A significant difference indicates PCB failure.
● Test the protection board thoroughly and replace if faulty.
5. Unstable Battery Voltage
● Cause A: Poor welding connections
● Solution: Use an internal resistance meter to check the interal resistance of battery. If exceeds the predetermined value, it means the welding state of the battery is wrong, the battery needs to be disassembled and re-welded.
● Cause B: Faulty protection board
● Solution: Replace the protection board.
● Cause C: Loose terminals or connectors
● Solution: Replace terminals or connectors.
6. Normal Charging but No Discharge / Discharge but No Charge
● Cause: damaged PCB
● Solution: Replace the protection board.
