Procell Constant AAA (PC2400)

Procell Constant AAA (PC2400) is a professional-grade 1.5V alkaline battery designed for low, consistent power draw. It delivers predictable performance across common workplace devices while supporting bulk procurement and long-term storage.

When to choose this battery

• Use for low-drain devices: TV/AC remotes, wall clocks, wireless mice/keyboards, laser pointers, glucometers, basic sensors.
• Choose for consistent discharge needs and long storage cycles (up to 10-year shelf life when stored properly).
• Good fit for healthcare, hospitality, offices, education, and facilities maintenance.

Avoid if

• You need high or pulsed current (e.g., motorized toys, LED flashlights on turbo, camera flashes). Consider Procell Intense AAA or lithium AAA instead.
• You operate in extreme cold/heat beyond typical indoor ranges; lithium AAA (L92) performs better in harsh environments.
• You require rechargeability or frequent cycling; consider NiMH AAA rechargeables.

Practical runtime expectations

Actual runtime varies by device load and cut-off voltage, but typical low-drain use cases see:

• TV/AC remote: about 6–18 months
• Wall clock: about 12–24 months
• Wireless mouse/keyboard: about 1–6 months (usage and polling rate dependent)
• Glucometer/thermometer: months to a year with intermittent use

Note: High-brightness flashlights or motorized devices will shorten runtime significantly.

Key benefits

• Predictable, steady output matched to low, continuous drains.
• Long shelf life (up to 10 years when stored at room temperature, in original packaging).
• Mercury-free alkaline chemistry; compliant with common ANSI/IEC standards.
• Bulk-friendly packaging options support fleet maintenance and reduced changeouts.

Specifications

Size / Format	AAA (LR03 / ANSI 24A)
Nominal Voltage	1.5 V
Chemistry	Alkaline (Zn/MnO₂)
Operating Temp	-20°C to 54°C (-4°F to 129°F)
Dimensions	Ø 10.5 mm × 44.5 mm
Typical Weight	≈ 11 g
Shelf Life	Up to 10 years (proper storage)

Note: Alkaline AAA capacity depends strongly on load and cutoff; expect higher usable capacity at low currents typical of remotes and clocks.

Compatibility and installation

• Fits any device requiring AAA/LR03 1.5V alkaline cells.
• Match polarity (+/−) as marked; do not force into the compartment.
• Do not mix old and new batteries or different brands/chemistries within the same device.

Storage and safety

• Store cool, dry, and out of direct sunlight; keep in original packaging until use.
• Do not recharge, disassemble, or dispose of in fire.
• Remove batteries from devices stored long term to reduce leakage risk.
• Recycle where available; follow local regulations.

Alternatives

• Procell Intense AAA: better for high-drain or frequent pulse loads.
• Lithium AAA (e.g., L92): best for extreme temperatures, lighter weight, and longest low-drain runtime.
• NiMH rechargeable AAA (e.g., 700–1000 mAh): economical for high-use devices with frequent replacements.

FAQ

Are these batteries rechargeable?

No. PC2400 are single-use alkaline cells. Do not attempt to recharge.

What is the difference between Procell Constant and Procell Intense?

Constant is optimized for low, steady drains (remotes, clocks, sensors). Intense is tuned for high or pulsed drains (flashlights, hand sanitizers with pumps, cameras) where current spikes are common.

Will they work in cold environments?

They operate down to about -20°C (-4°F), but performance declines in the cold. For frequent cold exposure, consider lithium AAA.

How should I store them for maximum life?

Keep at room temperature (15–25°C / 59–77°F), dry, and in original packaging. Avoid refrigeration and high humidity.

Can I mix different battery brands or types?

No. Mixing can cause leakage or shortened runtime. Replace all cells in a device at the same time with identical type and brand.
