Package Contents

• 1× FMA 3.7V Li-ion Battery Pack (capacity and connector as selected)

How to Install

1. Power off your device completely before replacing the battery.
2. Open the battery compartment and remove the old battery pack.
3. Verify the connector type matches your device’s battery port (SMP or XHR).
4. Insert the new FMA battery pack, observing correct polarity: Red wire (+), Black wire (−).
5. Connect the battery connector to the device port firmly — grip the connector body, do not pull the wires.
6. Close the battery compartment and power on the device to verify normal operation.
7. Charge using a Li-ion charger rated for 3.7V / 4.2V max. The built-in PCM will cut off at full charge (4.2V) and over-discharge (3.0V).

Important Cautions

• ⚠️ Use only a Li-ion charger rated for 3.7V (4.2V max). Never use Ni-MH, Ni-Cd, or unregulated chargers.
• ⚠️ Verify connector type and polarity before connecting. Incorrect polarity may damage the PCM or device.
• ⚠️ Do not short-circuit, puncture, crush, or disassemble the battery pack.
• ⚠️ Do not charge a damaged or swollen battery. Discontinue use immediately if abnormalities are detected.
• ⚠️ Do not expose to water, moisture, or extreme temperatures (charge/discharge: 0°C–45°C; storage: −20°C–35°C).
• ⚠️ Keep away from flammable materials during charging. Charge in a well-ventilated area.
• ⚠️ Keep out of reach of children.

Safety Information

• Charging: Use a Li-ion charger (4.2V max). Do not overcharge or leave charging unattended for extended periods.
• Storage: Store at ~50% charge (~3.8V) in a cool, dry place (−20°C–35°C). Avoid full charge for long-term storage.
• Operation: Do not short-circuit, puncture, crush, or disassemble. Avoid exposure to water or moisture.
• Temperature: Charge and discharge within 0°C–45°C. Do not charge below 0°C.
• Disposal: Discharge to safe voltage, then dispose of according to local lithium battery regulations. Do not incinerate.
• Inspection: Inspect before each use. Do not use if swollen, damaged, or leaking.
