Reliable Lithium Battery Solutions for Electronic Access Control Systems 🚪🔋

💡 Introduction

Electronic access control systems are essential for modern security management in office buildings, campuses, factories, and smart homes. These systems — including card readers, electric locks, and control panels — require a stable DC power source for uninterrupted operation. When grid power fails, the reliability of the backup battery becomes critical.

PKNERGY, a Shenzhen-based custom lithium battery manufacturer, provides safe and durable power solutions for access control and smart security, trusted by global system integrators.

⚙️ Power Demands and Challenges

Access control systems integrate multiple modules — RFID or fingerprint readers, control boards, and communication units — all relying on a stable DC power supply. Traditional lead-acid batteries are bulky and short-lived, leading to frequent maintenance. Key challenges include:

🔋 Reliable backup operation during grid failure
📏 Compact battery design for wall-mounted or embedded systems
🌡️ Stable performance in –20°C to +60°C environments
🧩 Long service life (>2000 cycles) to minimize maintenance
🛡️ Compliance with global standards for public safety devices
