Procell Intense AA (PX1500)

Procell Intense AA (PX1500) is a professional 1.5V alkaline (LR6) battery optimized for high‑drain, pulse‑load devices. It is designed to maintain stable voltage during short, high‑current bursts common in electronic locks, high‑output flashlights, motion sensors, and select medical tools.

When to choose it

• Use if: Your device draws intermittent high current (motors, solenoids, bright LEDs) or must work reliably under frequent pulses.
• Consider alternatives if:
  • Extreme cold (below 0°F / −18°C): Use Lithium AA (FR6/L91) for better low‑temperature performance.
  • Daily recharge cycles: Use low‑self‑discharge NiMH AA (e.g., 1900–2500 mAh) to lower total cost of ownership.
  • Very low‑drain devices (clocks, basic remotes): Procell General Purpose AA may be more cost‑effective.

Key specs

• Chemistry: Alkaline (zinc–manganese dioxide)
• Size / IEC: AA / LR6
• Nominal voltage: 1.5 V
• Operating temperature: approximately −4°F to 130°F (−20°C to 54°C)
• Shelf life: long shelf life suitable for bulk stocking (check date code on packaging)
• Construction: Mercury- and cadmium‑free; non‑rechargeable

Performance notes and realistic expectations

• High‑drain advantage: Formulated for lower internal resistance to better handle short, heavy current draws with less voltage sag than general‑purpose alkaline cells.
• Runtime varies by load: Alkaline capacity depends strongly on current draw and temperature. Expect shorter runtimes at higher currents and in cold environments.
• Typical examples (guidance, not guarantees):
  • LED flashlight ~300 mA continuous: around 1–2 hours near peak brightness before noticeable dimming; total usable time can extend to several hours at reduced output.
  • Electronic door lock (intermittent pulses): multi‑month service life is common; actual duration depends on lock model, door alignment, and usage frequency.
  • Motion sensor or soap dispenser: improved stability on activation pulses versus general‑purpose alkaline cells.

Installation and care

• Match polarity (+/−) and replace the full set together to prevent imbalance.
• Do not mix old and new batteries or different brands/chemistries in the same device.
• Keep contacts clean and dry; wipe with a dry cloth if needed.
• Storage: cool, dry place; avoid heat and direct sun. No refrigeration required.
• Remove batteries from devices stored more than 3 months to reduce leakage risk.
• Recycle or dispose per local regulations; never incinerate or attempt to recharge.

Compatibility and alternatives

• Compatible with any device specifying AA 1.5 V alkaline or LR6 cells.
• For low‑drain: Procell General Purpose AA may reduce cost with similar results.
• For harsh environments or very cold weather: Lithium AA (FR6/L91) offers better low‑temperature and long‑runtime performance.
• For frequent daily use: Rechargeable NiMH AA can lower ongoing cost and waste.

Buying and inventory tips

• Purchase from authorized suppliers to avoid counterfeit product.
• Check and record the date code; use a first‑in, first‑out (FIFO) rotation system.
• Stock in sealed bulk packs until needed to preserve shelf life.

FAQ

Is the Procell Intense AA (PX1500) rechargeable?

No. It is a primary (single‑use) alkaline battery. Do not attempt to recharge it.

How does Procell Intense differ from Procell General Purpose?

Intense is optimized for high‑drain, pulse‑load performance (lower internal resistance, better voltage stability under load). General Purpose targets low‑to‑moderate drain devices at a lower cost.

What is the shelf life?

PX1500 has a long shelf life suitable for bulk stocking; always confirm the printed date code on the pack and rotate stock accordingly. Store in a cool, dry place.

Can I use it in smoke alarms?

Some smoke and CO alarms use AA cells; PX1500 will work if the device specifies AA alkaline. For always‑on, low‑drain devices, a general‑purpose alkaline may be more economical, while lithium AA offers longer life in cold areas.

What temperatures can it handle?

Typical operating range is about −4°F to 130°F (−20°C to 54°C). For temperatures below 0°F (−18°C), lithium AA performs better.
