Product Features

1. High Energy Density: With an energy density of approximately 1024 Wh/L and 480 Wh/kg, it is ideal for space-constrained devices.
2. Wide Temperature Adaptability: It can discharge normally at an extreme low temperature of -60 °C and maintain stability at a high temperature of up to +85 °C.
3. Ultra-Low Self-discharge: It can retain > 90% of its rated capacity even after long-term storage.
4. Pulse Discharge Advantage: Suited for sensors, trackers, and other devices with intermittent high-power requirements.
5. Reliable Packaging: Featuring glass-to-metal sealing, a stainless steel can, and non-flammable electrolyte, it complies with safety standards such as UL and EN 50020.
6. Long Service Life: Designed to last over 10 years, making it perfect for remote or hard-to-maintain systems that do not require battery replacement.

Structure and Composition

• Wound Cell: The internal wound positive and negative electrode materials enhance volume utilization.
• Glass-to-metal Sealing: Prevents gas leakage and external corrosion.
• Stainless Steel Casing: Provides mechanical strength and impact resistance.
• Non-flammable Electrolyte: Improves safety and meets environmental regulations (RoHS, REACH) in multiple countries.

Typical Application Fields

• Utility meters (electricity meters, gas meters)
• IoT nodes and remote sensors
• Asset tracking and anti-theft systems
• Alarm and security monitoring devices
• Medical equipment (e.g., implantable or portable monitors)
• Industrial automation modules that require long-term power supply and are difficult to replace batteries for

Installation and Maintenance Guidelines

• Storage Environment: Keep in a dry, well-ventilated area with a temperature ≤ +30 °C; avoid high temperatures, humidity, or chemical corrosion.
• Short-circuit Prevention: Ensure correct polarity during installation and prevent direct contact between metal components and electrodes.
• Non-rechargeable: As a primary battery, charging, reverse discharging, or forced charging with an external power source is strictly prohibited.
• Replacement Cycle: Based on actual discharge curves and operating environments, it can usually continue to be used for over 10 years; if there is a significant voltage drop or casing damage, replace it promptly.
• Safe Disposal: Used batteries should be sent to recycling facilities qualified for hazardous waste treatment; do not incinerate or discard them at will.
