Custom Li-MnO₂ Battery Packs

What Are Lithium Manganese Dioxide (Li-MnO₂) Batteries?

Lithium Manganese Dioxide (Li-MnO₂) batteries are non-rechargeable lithium batteries, known for their 3V output, lightweight design, and reliability. They are available in cylindrical, coin, and prismatic forms, making them versatile for numerous applications and environmental conditions.

Types & Construction of Li-MnO₂ Cells

Available as cylindrical, coin, and prismatic shapes, Li-MnO₂ batteries employ bobbin-type structures for steady, low-drain scenarios, or spiral-wound designs for powerful, high-drain and pulse-demanding devices.

Key Features & Benefits

High Energy Density

Lightweight design with superior energy density for extended device runtime and compact form factors.

Wide Temperature Range

Reliable operation from -40°C to +80°C, perfect for extreme environmental conditions and outdoor applications.

Stable Voltage Output

Consistent voltage delivery with ultra-low self-discharge rate of less than 3% per year for long-term reliability.

High Discharge Current

Superior pulse and continuous discharge capabilities for high-performance applications and demanding power requirements.

Extended Lifespan

Long operational and shelf life engineered for maximum return on investment and reduced maintenance costs.

Safety Certified

Full compliance with international safety and environmental standards including CE, UL, UN38.3, and RoHS certifications.

Working Principle

The positive electrode is manganese dioxide (MnO₂)

The negative is lithium

Main reaction: MnO₂ + Li → MnO₂Li

These batteries provide a stable 3V output and a reliable power supply throughout their cycle.

Storage & Safety

Store at temperatures below 30°C for optimal lifespan. Engineered for reliable performance even after long periods of storage, minimizing voltage delay and risk of passivation.

Safe construction allows for use in specialized or potentially hazardous environments with the correct certifications.

Li-MnO₂ Battery Pack Frequently Asked Questions

Q1

What are the main advantages of lithium manganese dioxide (Li-MnO₂) batteries compared to other lithium batteries?

Li-MnO₂ batteries offer high energy density, a long shelf life, stable performance across a wide temperature range, and strong safety features. They are especially suitable for small devices that require reliable, long-lasting primary (non-rechargeable) power sources.

Q2

In which applications are Li-MnO₂ batteries most commonly used?

Li-MnO₂ batteries are widely used in medical devices, wearable electronics, IoT sensors, security systems, memory backup, and other portable devices where a compact, reliable, and non-rechargeable power source is needed.

Q3

Are Li-MnO₂ batteries rechargeable, and can they be reused after depletion?

No, Li-MnO₂ batteries are primary batteries designed for single-use only. They are not rechargeable and should be properly disposed of or recycled after they are depleted.

Q4

How should Li-MnO₂ batteries be stored and handled to ensure the best performance?

Store Li-MnO₂ batteries in a cool, dry place, away from direct sunlight and sources of heat. Avoid short-circuiting, puncturing, or dismantling the batteries, and always follow local regulations for proper disposal.
