Procell Intense CR123A Battery

The Procell Intense CR123A is a primary (non‑rechargeable) 3V lithium battery engineered for devices that draw short, high bursts of current. It supports stable voltage delivery under load, helping critical equipment perform predictably.

At a glance

• Chemistry: Lithium‑manganese dioxide (primary, Li‑MnO2), 3V
• Size/format: CR123A (also labeled 123, 123A, DL123)
• Optimized for: High‑drain and pulse‑load profiles
• Use cases: PIR motion sensors, glass‑break sensors, high‑output flashlights, optics, industrial/wireless transmitters
• Stocking: Long shelf life suitable for spares and multi‑site rollouts

When to choose this battery

• Use if your device shows voltage dips, false alarms, or dimming during bursts (e.g., sensor wake‑and‑transmit, flashlight turbo modes).
• Use for frequent on/off cycling or high‑lumen lighting where stable output matters.
• Avoid if your device is steady, low‑drain and cost is the priority—general‑purpose CR123A may suffice.
• Avoid if your device requires or explicitly supports only rechargeables (16340/RCR123A). Do not substitute types.

Device fit and compatibility

• Fits devices that specifically call for CR123A/123/DL123.
• Do not use in place of 16340/RCR123A (rechargeable) unless the device manual lists CR123A as approved.
• For multi‑cell devices, replace all cells at once and use identical brand and age.
• Observe polarity and manufacturer guidance for replacement intervals.

Estimating runtime (planning only)

Runtime depends on average current, pulse profile, cutoff voltage, and temperature.

Simple estimate: runtime (hours) ≈ nominal capacity (mAh) ÷ average current (mA). For example, if your device averages 50 mA, a typical CR123A capacity of about 1500 mAh (reference value for planning, not a guarantee) suggests roughly 30 hours of active draw. High pulse currents and cold conditions reduce this.

Example: sensor with bursts

• Assumptions: sleep 10 µA most of the day; 100 events/day; each event draws 100 mA for 1 second.
• Daily use from bursts: 100 mA × (100 s ÷ 3600) ≈ 2.78 mAh
• Daily use from sleep: 0.01 mA × 24 h ≈ 0.24 mAh
• Total ≈ 3.0 mAh/day → a 1500 mAh reference capacity suggests ~500 days in ideal conditions. Real‑world runtimes are typically lower due to pulse losses and temperature.

Alternatives

• General‑purpose CR123A: Consider for steady, moderate loads to reduce cost per device.
• Rechargeable 16340/RCR123A: Choose if your device supports them and you have charging procedures in place. Expect different voltage behavior and runtime per cycle.

Storage, handling, and safety

• Do not recharge. This is a primary lithium cell.
• Store cool, dry, and in original packaging; rotate stock FIFO.
• Prevent short circuits: keep terminals covered; do not carry loose with metal tools/keys.
• Do not mix old/new cells or brands in the same device.
• Follow local regulations for lithium battery recycling/disposal.

Deployment tips for teams

• Standardize on Procell Intense CR123A for high‑drain endpoints to reduce callbacks.
• Label install dates; start with conservative replacement intervals and extend using field data.
• Clean contacts during service and verify spring tension/fit before closing housings.

FAQ

Is the Procell Intense CR123A rechargeable?

No. Never attempt to recharge a primary lithium cell.

What devices benefit most?

Security sensors, high‑output flashlights, wireless transmitters, and instruments that draw short, heavy bursts of current.

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

No. Replace all cells in a device at the same time with matching brand and age.

Will it work in cold environments?

It is designed for dependable service across typical indoor and many controlled outdoor conditions. Expect reduced runtime in very cold temperatures, as with any battery.

What are the size equivalents?

CR123A is commonly labeled 123, 123A, or DL123. Confirm your device manual before purchase.
