Energizer Industrial EN92

Energizer Industrial EN92 AAA Alkaline Battery

The EN92 is Energizer’s professional-grade AAA alkaline (LR03) cell supplied in bulk packaging for business, institutional, and service environments. It provides dependable 1.5 V power with leak-resistant construction for meters, sensors, diagnostic tools, and control devices that demand predictable performance and easy inventory management.

When to Choose EN92

• Use for single-use, moderate-drain devices where reliability and cost control matter (sensors, remotes, handheld meters, glucometers, digital thermometers).
• Good fit for standardized fleets and maintenance kits thanks to consistent date codes and bulk packs.

When to Consider Alternatives

• Choose lithium AAA (e.g., L92) for extreme temperatures, high-drain bursts, or extended shelf storage with lighter weight.
• Choose NiMH rechargeable AAA (HR03) for frequently cycled devices (training remotes, scanners) to reduce waste and total cost over time.

Key Advantages

• Professional bulk packaging for efficient stocking and reduced waste (no retail blister packs).
• Leak-resistant design to help protect sensitive equipment.
• Predictable performance across common industrial and commercial duty cycles.
• Mercury- and cadmium-free.

Typical Specifications

Attribute	Details
Chemistry	Alkaline (Zinc–Manganese Dioxide)
Size	AAA
IEC / ANSI	LR03 / 24A
Nominal Voltage	1.5 V
Discharge Cutoff (typ.)	~0.8 V
Dimensions	Diameter 10.5 mm (0.41 in); Length 44.5 mm (1.75 in)
Typical Weight	~11 g (0.39 oz)
Operating Temperature	Approx. -18°C to 55°C (0°F to 130°F)
Shelf Life	Multi-year; check package/date code for rated storage (store at ~20–25°C)
Packaging	Bulk cartons/trays for commercial use

Runtime Examples (Per Cell, Approximate)

• Low-power sensor (0.2 mA average): up to ~6,000 hours (about 8 months).
• Handheld instrument (15 mA continuous): ~60–80 hours.
• Compact flashlight (300 mA): ~2–4 hours depending on mode and cutoff.

Actual runtime varies with device load profile, temperature, and cutoff voltage. Devices using multiple cells in series will scale runtime by the device’s total current draw, not the number of cells.

Common Uses

• Wireless sensors and data loggers
• Medical and diagnostic tools (check device guidance for approved chemistries)
• Remote controls and control panels
• Digital thermometers, laser pointers, and small flashlights

Compatibility and Cross-References

• Use wherever AAA / LR03 / 24A / MN2400 is specified.
• Do not substitute with rechargeable cells unless the device explicitly supports NiMH (1.2 V nominal) chemistry.

Storage and Handling

• Store in a cool, dry place at room temperature; avoid heat and direct sunlight.
• Keep in original packaging until use; rotate stock using FEFO (First-Expire, First-Out).
• Replace all cells in a device at the same time; do not mix old and new or different brands/chemistries.
• Do not recharge, disassemble, or incinerate. Recycle where available.

Pros and Cons

• Pros: Cost-effective in bulk, widely compatible, predictable performance, leak-resistant.
• Cons: Lower high-drain/low-temperature performance than lithium; single-use (not rechargeable).

FAQ

Is EN92 the same as consumer AAA batteries?

Performance is comparable, but Industrial versions are packaged for business (bulk cartons, consistent date codes) and optimized for large deployments and storage handling.

Can I recharge EN92 batteries?

No. EN92 is a primary (single-use) alkaline cell. Use NiMH rechargeables (HR03) if you need recharging.

What if my device requires operation below freezing?

Choose lithium AAA (e.g., L92) for better low-temperature performance; alkaline capacity drops significantly below 0°C (32°F).

How long can I store EN92 before use?

It has a multi-year shelf life when stored at room temperature. Always check the date code on the pack and follow FEFO rotation to ensure peak performance.

Can I mix EN92 with other brands or partially used cells?

No. Mixing can cause leakage, reduced performance, or device errors. Replace the full set with matching new cells.
