Product Precautions
Dedicated Charger: Only use a lithium-ion battery charger with matching voltage and current parameters (16.8V). Direct charging with non-regulated power supplies or lead-acid battery chargers is strictly prohibited, as this may cause fire or explosion.
Prohibited Actions: Do not disassemble, crush, or puncture the battery pack. Do not short-circuit the battery (positive and negative terminals touching). Do not place the battery in fire or high-temperature environments (such as inside a car exceeding 60°C).
Operating Environment: Avoid using and storing the battery in extreme temperatures (too high or too low), humid, dusty, or corrosive gas environments.
Installation and Fixing: When installing the battery pack in equipment, ensure it is securely fixed to prevent shaking. The output wires should be protected from being cut by sharp objects or excessively bent.
Handling Abnormalities: If the battery pack casing is severely deformed, bulging, leaking, emitting an odor, or experiencing an abnormal temperature increase, immediately stop using it and place it in a safe, open area away from flammable materials. Contact a professional for assistance.
Disposal: After the battery reaches the end of its lifespan, do not dispose of it arbitrarily. It should be handled by a designated battery recycling agency in accordance with local regulations.
FAQ
Q1: Can this battery pack directly replace the old battery in my device?
A: Yes, but three key conditions must be met: 1) The voltage must be exactly the same (is the nominal voltage of your old battery 14.8V/14.4V?); 2) The physical dimensions must fit (please check if your battery compartment dimensions are greater than or equal to 19*68*75mm); 3) The output terminal interface type must match. It is recommended to carefully check the parameters of your original battery before replacement.
Q2: What is the specific function of the battery pack's protection board?
A: The protection board is the "safety guard" of the battery. It monitors the battery status in real time: it automatically cuts off charging when the voltage reaches 16.8V (overcharge protection); it automatically cuts off the output when the voltage discharges to approximately 10.0V (over-discharge protection); and it will quickly cut off the circuit when the output current exceeds the set safety value or in case of an accidental short circuit between the positive and negative terminals (overcurrent/short circuit protection), thus protecting the battery and the connected equipment.
Q3: How do I charge this battery pack? How long does it take to charge?
A: Please be sure to use a lithium-ion battery charger with an output voltage of 16.8V and a recommended output current of around 1.6A (0.5C). Using a standard 1.6A charger, it takes approximately 2-3 hours to fully charge a completely depleted battery. Using a higher current charger (such as 3A) will shorten the charging time, but may slightly affect the battery's cycle life.
Q4: Can the battery pack be left connected to the device for a long time?
A: If the device itself has a physical power switch and the standby current is very low (microampere level) when switched off, it is acceptable for short periods. However, long-term connection (such as several weeks or more) is not recommended. For devices without a physical switch or with a high standby current, long-term connection may lead to over-discharge and damage the battery. When not in use for extended periods, it is recommended to remove the battery pack from the device and store it separately in a partially charged state.
Q5: What is the lifespan of the battery pack?
A: Battery life is usually measured in terms of charge and discharge cycles. Under normal operating conditions (ambient temperature, standard charging and discharging current), this battery pack can withstand approximately 500 complete charge-discharge cycles while maintaining more than 80% of its initial capacity. Actual lifespan may be affected by usage habits and ambient temperature.
