Core Advantages: An All-in-One Power Solution for Smart Door Locks

Ultra-Long Battery Life – Say Goodbye to Frequent Charging

• 4000mAh High Capacity: Designed for fully automatic lock bodies (e.g., motor-driven, facial recognition, and other high-power scenarios). A single charge provides 3-4 months of battery life, significantly outperforming the mainstream 3200mAh models (only 2-3 months).
• Low Self-Discharge Technology: Less than 2% monthly self-discharge in idle conditions, ensuring long-term standby without worries.

Wide Temperature Range – Reliable in All Climates

• Stable Power Supply at -20°C: Utilizes low-temperature electrolyte technology to release 85% of battery capacity even at -20°C, fearless of harsh northern winters.
• Safe Protection at 60°C: Built-in thermal control chip automatically limits current at high temperatures, eliminating overheating risks.

High Discharge Rate for Faster Response

• Pulse Discharge Capability: Instantly drives high-power motors (like fully automatic bolts) and cameras, enhancing unlock speed by 30% with no lag or delays.
• Smart Voltage Stabilization: Voltage fluctuation within ±0.1V, preventing system crashes or false alarms due to unstable voltage.

Technical Specifications

Scenario-Based Solutions

• Fully Automatic Smart Locks: 4000mAh capacity + pulse discharge easily powers high-torque motors, handling up to 50 openings daily with ease.
• Models with Cameras/Smart Peepholes: In scenarios involving 24/7 motion detection and video recording, battery life still exceeds 2 months (compared to only 1.5 months for similar products).
• Optimized Dual-Battery Compartment Solution: Supports automatic switching between main and backup batteries. When paired with the same model, battery life can double to 8 months.

Safety and Maintenance Guide

Safety Warnings

• Do not use non-compatible chargers (recommended: 5V/2A USB-C port, full charge in 3 hours).
• Immediately discontinue use if the battery is swollen or leaking and contact after-sales service.

Maintenance Tips

• For long-term storage: Maintain 50% charge and recharge every 3 months.
• For winter usage: In -20°C environments, reduce charging intervals to every 2 months to prevent deep discharge.
