Procell Constant AA (PC1500)

Procell Constant AA (PC1500) is a professional-grade 1.5V alkaline (LR6) battery optimized for steady, low-current devices. It prioritizes consistent voltage, predictable runtimes, and a long shelf life, making it a reliable choice for facilities that manage large fleets of battery-powered equipment.

When to choose this battery

• Wall clocks, analog/digital thermometers, and environmental sensors (steady microamp to low milliamp draw)
• TV and A/V remote controls, presentation clickers, keyless entry pads
• Smoke/CO alarms and combination alarms that specify AA cells (follow device instructions)
• Wireless computer mice and keyboards in office use (light-to-moderate duty)
• Test instruments and medical peripherals with low, continuous loads (always confirm device specs)

Choose an alternative if

• High-drain/pulsed loads: Flash cameras, motorized toys, wireless microphones, high-output flashlights – use Lithium AA or Procell Intense AA.
• Extreme temperatures: Below -20°C (-4°F) or above 54°C (130°F) – Lithium AA performs better.
• Frequent cycling/recharge: If you need rechargeability, use NiMH AA with a compatible charger.

Key specifications

• Size/Type: AA alkaline (LR6, ANSI 15A)
• Nominal voltage: 1.5 V
• Typical delivered capacity: approximately 2000–3000 mAh depending on load, temperature, and cutoff
• Operating temperature range: -20°C to 54°C (-4°F to 130°F)
• Shelf life: up to 10 years in storage (cool, dry conditions)
• Mercury-free; single-use (non-rechargeable)

Expected runtimes (rule-of-thumb)

Actual runtime depends on device load, duty cycle, and environment. These rough ranges help with planning:

• Wall clocks: 1–2 years
• Remote controls: 6–24 months (usage dependent)
• Smoke/CO alarms using AA: typically ~1 year (test monthly; replace per manufacturer guidance)
• Wireless mouse/keyboard: 2–12 months depending on usage and power settings
• Low-power sensors (10–50 µA): many months to multiple years

Compatibility and fit

• Standard AA dimensions (approx. 14.5 × 50.5 mm); fits devices calling for AA, LR6, or 15A cells
• Works as a direct replacement for common consumer AA alkaline batteries (e.g., Duracell Coppertop AA, Energizer MAX AA)
• Do not mix with other chemistries (lithium, rechargeable NiMH) or partially used cells

Storage, handling, and maintenance

• Store cool and dry (ideally 10–25°C / 50–77°F); avoid heat and direct sunlight
• Keep in original packaging until use; rotate stock FIFO to leverage the 10-year shelf life
• Install with correct polarity; clean device contacts if corroded
• Remove batteries from devices stored long term or not in regular use
• Do not attempt to recharge, short-circuit, or disassemble; keep away from children
• Recycle through local battery recycling programs where available

Procurement tips

• For fleets, standardize on one chemistry per device type to simplify maintenance
• Label install dates on devices or use a maintenance log to schedule proactive replacements
• Buy in bulk packs for consistent lot codes and easier inventory management

FAQ

Is the PC1500 rechargeable?

No. It is a single-use alkaline cell. Use NiMH AA if you need rechargeability.

Can I use it in high-drain devices like camera flashes or pro audio gear?

It will work but may have shorter runtimes. For high-drain or pulsed loads, choose Lithium AA or Procell Intense AA for better performance.

How does temperature affect performance?

It operates from -20°C to 54°C (-4°F to 130°F). Capacity drops in cold; for very cold or hot environments, Lithium AA maintains performance better.

What does “up to 10-year shelf life” mean?

When stored unopened in cool, dry conditions, the battery retains usable capacity for up to 10 years. Always check date codes and rotate inventory.

Is it safe for smoke or CO alarms?

Yes, if the alarm specifies AA alkaline cells. Follow the alarm manufacturer’s replacement schedule and test monthly.
