Renata CR2325 (Lithium Coin)

Renata CR2325 Lithium Coin Cell (3V, 23 × 2.5 mm)

The Renata CR2325 is a primary (non-rechargeable) lithium manganese dioxide coin cell sized 23 mm in diameter and 2.5 mm in height. Compared with the thinner CR2320, it offers higher capacity for longer intervals between changes in the same 23 mm footprint.

Key Specs

• Chemistry: Lithium Manganese Dioxide (Li–MnO₂)
• Nominal Voltage: 3V (fresh cells typically read ~3.0–3.2V open circuit)
• Typical Capacity: ~160–190 mAh (varies by brand, load, and cutoff)
• Size: 23 mm diameter × 2.5 mm height
• Operating Temperature: −30°C to +60°C (−22°F to +140°F)
• Compliance: Mercury-free; RoHS compliant

When to Choose CR2325

• Use if your device specifies CR2325 or 23×2.5 mm.
• Prefer over CR2320 when you want longer runtime in the same 23 mm diameter.
• Works well in low-to-moderate drain devices with intermittent pulses: keyless entry remotes, medical or fitness sensors, small security devices, watches, calculators, and memory/RTC backup.

Avoid or Consider Alternatives

• Do not substitute on thickness: CR2320 (2.0 mm) may lose contact; CR2330 (3.0 mm) may not fit or can damage the holder.
• Not suitable for sustained high current draw. For continuous loads above ~10–20 mA, use a cell type the device manufacturer recommends (e.g., rechargeable Li-ion or primary cylindrical lithium).
• Never stack coin cells to change voltage or thickness.

Compatibility & Cross-Reference

Common equivalents include CR2325 (IEC), DL2325 (Duracell), and ECR2325 (Energizer). Always match size (23×2.5 mm) and voltage (3V) and confirm fit in your device manual.

Expected Runtime (Quick Estimate)

Use this simple approximation for planning:

Estimated runtime (hours) ≈ capacity (mAh) ÷ average load (mA)

• Very low drain (0.05 mA): ~3,200–3,800 hours (≈4.5–5.5 months)
• Moderate load (1 mA): ~160–190 hours (≈7–8 days)

Actual results vary with pulse currents, temperature, and device cutoff voltage. Devices that transmit in bursts (e.g., remotes) may show voltage dips near end of life.

Installation Tips

• Verify the original part number or device specification calls for CR2325.
• Observe polarity: the marked (+) face is typically the top.
• If contacts are dull or oxidized, gently clean before installing; avoid bending contact springs.
• Do not mix old and new cells or different brands/chemistries in the same device.
• If operation is intermittent, re-seat the cell and verify contact pressure and correct orientation.

Storage & Shelf Life

• Store in original packaging at 10–25°C (50–77°F) with low humidity.
• Avoid heat, direct sunlight, and freezing. Do not store loose with metal objects.
• Fresh cells have very low self-discharge; check date code. Replace if open-circuit voltage is below ~2.9V.

Safety & Disposal

• Keep coin cells away from children and pets. Ingestion can be life-threatening—seek immediate medical attention if swallowed.
• Do not recharge, short, crush, or incinerate.
• Tape terminals of used cells and recycle or dispose per local regulations to prevent short circuits.

FAQ

Can I use a CR2320 or CR2330 instead of a CR2325?

Not recommended. CR2320 is thinner (2.0 mm) and may lose contact; CR2330 is thicker (3.0 mm) and may not fit or could damage the holder. Use the size specified by your device.

What capacity should I expect?

Most reputable brands rate CR2325 around 160–190 mAh. Usable capacity depends on load profile, temperature, and device cutoff voltage.

Is the Renata CR2325 rechargeable?

No. CR2325 is a primary (non-rechargeable) lithium cell. Do not attempt to recharge it.

How does CR2325 compare to CR2032?

CR2325 is larger in diameter (23 mm vs 20 mm) and thicker than CR2032, and it typically offers more capacity. Only use the size your device is designed to accept.

How can I tell if the battery is near end of life?

Measure voltage under load or observe device behavior. Rapid voltage sag during pulses or repeated low-battery warnings indicate it’s time to replace.
