Energizer LN92 AAA Industrial Lithium Batteries

Energizer LN92 is the industrial AAA lithium (Li-FeS2) cell engineered for professional uptime. It provides longer runtime than alkaline in high and moderate-drain devices, reliable starts in cold environments, and a long shelf life—all in leak-resistant, barcoded packaging that supports fleet maintenance and inventory control.

When to Choose LN92

• High or variable-drain devices: barcode scanners, portable meters, compact transmitters.
• Cold-weather or outdoor use: sensors, access control, data loggers operating below freezing.
• Infrequent-use gear that must be ready: emergency kits, seasonal equipment, service spares.
• Programs focused on fewer changeouts and predictable performance.

Consider alternatives if

• You need rechargeable power (choose NiMH AAA with a suitable charger).
• Lowest upfront cost matters more than runtime (alkaline AAA for low-drain, indoor use).
• Your device prohibits lithium primary cells (check the device manual).

Key Advantages

• Extended runtime vs. alkaline in high-drain and low-temperature conditions.
• Flatter discharge curve for stable device performance.
• Lightweight construction to reduce carry weight in handheld and wearable gear.
• Leak-resistant design to help protect equipment during long deployments.
• Industrial packaging with barcodes/date codes for traceability and stocking efficiency.

Runtime Planning (Quick Guide)

Estimate continuous runtime by dividing usable capacity by your device’s average current draw. Example: at 120 mA average draw, 1,250 mAh provides roughly 10 hours of continuous operation. Duty-cycled devices (e.g., scanners used intermittently) will run proportionally longer. Cold temperatures and high surge currents reduce runtime; LN92 mitigates these effects better than alkaline.

Packaging and Procurement

• Available in industrial bulk boxes and master cases for streamlined distribution.
• Barcoded, traceable packaging supports audits and first-in/first-out (FIFO) stock rotation.
• Select case quantities that align with your preventive maintenance cycle to minimize partial boxes and waste.

Compatibility and Best Practices

• Compatible with devices that specify 1.5 V AAA cells. Check device documentation before switching chemistries.
• Do not recharge, short-circuit, disassemble, or incinerate. LN92 is a primary (single-use) battery.
• Do not mix new and used batteries, or different chemistries (e.g., lithium with alkaline or NiMH).
• Replace all cells in a device at the same time for best performance.

Storage and Safety

• Store in a cool, dry place (approx. 50–77°F / 10–25°C) away from direct sunlight and conductive materials.
• Keep in original packaging until use to prevent shorting and to preserve lot traceability.
• For bulk shipments, follow applicable lithium metal battery transport regulations (UN 3090/3091). Consult your carrier for current requirements.

Alternatives to Consider

• Rechargeable NiMH AAA: best for devices charged daily or with very frequent use.
• Alkaline AAA: suitable for low-drain, indoor applications with minimal peak current needs.
• Energizer L92 (consumer packaging): same chemistry as LN92, ideal for smaller, non-industrial buys.

FAQ

• Can LN92 replace standard AAA batteries? Yes. LN92 is a 1.5 V AAA cell and can replace alkaline AAA where lithium primary is allowed.
• Are LN92 batteries rechargeable? No. They are primary lithium cells and must not be recharged.
• How does LN92 perform in the cold? Lithium chemistry maintains power at low temperatures where alkaline performance drops sharply, supporting reliable cold starts.
• What shelf life should I expect? When stored properly at room temperature, LN92 can remain ready for use for up to 20 years.
• What pack size should I buy? Choose bulk or master cases for fleet maintenance and cost-per-cell savings; choose smaller packs for field kits and low-volume sites.

Bottom Line

For AAA devices that demand dependable power, long runtime, and cold-weather reliability, Energizer LN92 delivers industry-ready performance with the traceability and packaging that operations teams need.
