Compatibility
Verify polarity before connecting. The photographed sample uses black for GND (−) and red for VBAT (+), in the orientation shown. Confirm the polarity on the battery and device with a meter before connecting. Connector pitch and appearance alone do not establish compatibility. You are responsible for confirming that this battery suits your equipment and charger.
Battery handling
- Use a charger designed for single-cell LiPo chemistry, and follow the charger and equipment instructions.
- Do not leave the battery unattended while charging.
- Inspect the battery before each use. Do not use or charge it if it is swollen or damaged.
- Do not short, crush, puncture or bend the battery.
- Keep it away from heat, flammable materials and children.
