Its lightweight design (~7g) ensure durability in talking pens, voice recorders, and portable LED lights.
3. Charging & Maintenance Guidelines
- Charging: Use a balanced Li-ion charger set to 4.2V with CC/CV mode. Recommended charge current: 0.5C–1C.
- Discharge Cutoff: Avoid discharging below to 3.0V to prevent cell damage.
- Storage: Store at 3.7V–3.8V per cell in a cool, dry environment (10°C–25°C).
- Cycle Life: 300–500 cycles at 80% depth of discharge under normal operating conditions.
