Panasonic LRV08 Alkaline Single-Use Battery

Panasonic LRV08 Alkaline Single-Use Battery

Overview

The Panasonic LRV08 is a compact, high‑performance alkaline button cell designed for single‑use applications. With a nominal voltage of 12 V and a capacity of approximately 38 mAh, it delivers reliable power in a small footprint suitable for remote controls, key fobs, doorbell chimes, and other low‑current devices.

Technical Specifications

• Type: Alkaline (Manganese Dioxide) / Silver Oxide variant available
• Voltage: 12 V nominal
Capacity: ~38 mAh (typical for alkaline version)
• Dimensions: 28 mm × 10 mm (length × diameter)
• Weight: Approximately 1.5 g per cell
• Chemistry: Alkaline manganese dioxide with zinc anode; silver oxide variant uses silver oxide cathode for higher energy density.
• Operating Temperature Range: –20 °C to +60 °C (typical)
• Shelf Life: Up to 10 years when stored in a cool, dry environment

Design Features

The LRV08’s slender profile allows it to fit into tight spaces where larger cells cannot. Its robust metal casing protects the internal chemistry from mechanical shock and moisture ingress. The positive terminal is located on the top surface for easy contact with device contacts, while the negative side is recessed to prevent accidental shorting.

Performance Characteristics

Alkaline chemistry provides a stable voltage output over most of its discharge curve, making it ideal for devices that require consistent power. The silver oxide variant offers slightly higher energy density and lower self‑discharge, extending the usable life in standby mode.

• Discharge Rate: Suitable for low‑current (< 5 mA) applications; can handle brief bursts up to 20 mA without significant voltage drop.
• Self‑Discharge: <10 % per year (alkaline); <5 % per year (silver oxide).
• Peak Power Output: Up to 0.2 W during transient loads.

Applications

The LRV08 is engineered for a wide range of consumer electronics that demand small, reliable power sources:

• Remote Controls: Car key fobs, garage door openers, and wireless switches.
• Security Devices: Doorbell chimes, alarm system modules, and motion‑sensor lights.
• Portable Electronics: Small handheld devices such as digital thermometers, pocket flashlights, and toy controllers.
• Industrial Sensors: Low‑power sensors in HVAC units or smart meters where space is limited.

Compatibility

The LRV08 matches the standard A23 / MN21 / LR23A / GP23 / V23GA form factor, ensuring seamless interchangeability with existing devices that accept these button cells. Its 12 V output aligns with most low‑voltage circuits designed for this size.

Installation and Handling

Installing the LRV08 is straightforward: align the positive terminal with the device’s contact point, insert gently, and secure if required by a spring clip or adhesive. Avoid exposing the cell to extreme temperatures or moisture during installation to preserve its integrity.

• Do Not: Over‑compress the cell; this can damage internal contacts.
• Do Not: Expose to high humidity for extended periods.
• Safe Disposal: Recycle through local battery collection programs to recover valuable metals and prevent environmental contamination.

Environmental Considerations

Panasonic’s LRV08 is manufactured with a focus on sustainability. The alkaline version contains no mercury or other hazardous substances, while the silver oxide variant uses recyclable silver compounds. Proper disposal reduces ecological impact, and recycling programs recover precious metals for reuse.

Longevity and Reliability

Thanks to its robust chemistry and protective casing, the LRV08 delivers dependable performance over its rated lifespan. Even after prolonged storage, it retains a significant portion of its capacity, making it an excellent choice for backup or emergency devices that must remain ready at all times.

Conclusion

The Panasonic LRV08 Alkaline Single‑Use Battery combines compactness, reliable voltage output, and versatile compatibility to meet the needs of a broad spectrum of low‑power electronic applications. Its thoughtful design ensures that devices ranging from everyday remote controls to critical security systems can operate smoothly without the need for bulky power sources.
