Introduction
Security devices rely on different types of batteries depending on their application environments. The most commonly used batteries in security devices include lead-acid batteries, lithium batteries, and NiMH batteries. Each type has its own advantages and is preferred for specific kinds of security equipment.
What Are the Batteries Commonly Used in Security Devices?
Lead-Acid Battery
Lead-acid batteries, including valve-regulated lead-acid (VRLA) types, are often used in uninterruptible power supply (UPS) systems that provide backup power for fire alarm systems and monitoring centers.
They feature a high discharge rate and relatively low cost, providing sufficient power during a power outage to ensure the security system continues running without interruption.
Lithium Battery
Li-ion Battery:
Li-ion batteries are known for their fast charging speed, high energy density, and long cycle life. They are ideal for security devices that require frequent movement or higher power capacity, such as portable security inspection equipment and wireless surveillance cameras.
Li-MnO₂ Battery:
Li-MnO₂ batteries are primary lithium batteries. Common models such as CR123A and CR14250 are widely used in smoke detectors and burglar alarms. They offer high energy density, stable discharge voltage, light weight, and easy installation. Their low self-discharge rate makes them suitable for long-term standby devices.
Li-SOCl₂ Battery:
Li-SOCl₂ batteries are also non-rechargeable and offer an energy density of up to 430 Wh/kg. This type is ideal for security devices that require long-term, low-current power supply, such as remote sensors or data loggers.
NiMH Battery
NiMH batteries feature high capacity and long cycle life and operate reliably across a wide temperature range. They are suitable for backup power supplies in solar-powered monitoring systems, wireless cameras, and other security devices that undergo frequent charging and discharging cycles, such as spotlights.
How to Choose the Right Battery for Different Security Devices
| Security Device | Recommended Battery Type |
|---|---|
| Smart Surveillance Camera | Li-ion battery pack (e.g., 18650 battery pack, 1S2P configuration) |
| Uninterruptible Power Supply (UPS) | 12V Lead-acid battery or lithium battery pack |
| Smart Smoke Detector / Door Lock | Single Li-MnO₂ battery (CR123A, CR14250, CR17450) or Li-SOCl₂ battery (ER18505M) with a 1520 capacitor |
| Portable Security Inspection Equipment | Li-ion battery pack (e.g., ICR18650) |
| Door Sensor | Single Li-MnO₂ battery (CR2450) or Li-SOCl₂ battery (ER14250) for door and window status monitoring |
