Varta Electronics Battery – CR2320 Li

The Varta CR2320 Lithium Coin Cell is a compact, high‑performance power source designed for small electronic devices that demand reliable, long‑lasting energy. With its 3‑volt output and 135 mAh capacity, this single‑use battery delivers consistent performance in a lightweight, 2‑gram package.

Key Specifications

• Model: CR2320 (also listed as 06320 or 6320101401)
• Voltage: 3 V
• Capacity: 135 mAh
• Dimensions: Ø23 mm × 2.0 mm (standard CR2320 size)
• Weight: 2.9 g
• Technology: Lithium (non‑mercury, environmentally friendly)
• Type: Single‑use, non‑rechargeable coin cell
• Color: Silver (typical metallic finish for lithium cells)
• Package: Blister pack containing one unit

Why Choose the Varta CR2320?

The Varta CR2320 stands out for its combination of high energy density and stable voltage output. Its lithium chemistry ensures a flat discharge curve, meaning devices receive consistent power until the battery is fully depleted. This makes it ideal for:

• Key fobs and remote controls – where a small, long‑lasting battery can replace multiple standard 1.5 V cells.
• Portable medical devices – such as blood pressure monitors or glucose meters that require precise voltage levels.
• Wearable technology – including smartwatches and fitness trackers where space is at a premium.
• Industrial sensors – for monitoring temperature, humidity, or vibration in remote locations.

Performance Highlights

The 135 mAh capacity of the CR2320 translates to:

• A typical lifespan of 12–18 months when used in low‑drain devices (e.g., key fobs, small sensors).
• Up to 6–8 months in moderate‑drain applications such as digital thermometers or wireless keyboards.
• Consistent voltage output of 3 V throughout most of its life, with only a gradual drop near end‑of‑life.

Safety and Environmental Considerations

The Varta CR2320 is mercury‑free, aligning with modern environmental regulations. Its lithium chemistry provides high energy density while maintaining a low self‑discharge rate, reducing the risk of leakage or hazardous waste.

Installation and Compatibility

Installing the CR2320 is straightforward:

1. Locate the battery compartment on your device (usually a small slot with a removable cover).
2. Insert the CR2320 with the positive (+) side facing up, matching the polarity markings inside the compartment.
3. Secure the cover and test the device to ensure proper operation.

Because it matches the standard CR2320 size, it is interchangeable with other lithium coin cells of the same dimensions. However, always verify voltage compatibility before substitution.

Applications Across Industries

• Consumer Electronics: Key fobs, remote controls, small gaming devices, and portable audio accessories.
• Medical Devices: Blood pressure monitors, pulse oximeters, and other handheld diagnostic tools.
• Industrial & Commercial: Sensors for HVAC systems, smart meters, and RFID tags.
• Automotive: Small electronic modules in vehicles such as immobilizers or door locks.

Quality Assurance and Reliability

Varta’s reputation for rigorous testing ensures that each CR2320 battery meets stringent performance criteria. The company employs advanced manufacturing processes to guarantee:

• Consistent voltage output across the entire batch.
• Low internal resistance, which translates to higher efficiency in devices.
• Durability against temperature extremes and mechanical shock.

Conclusion

The Varta Electronics CR2320 Lithium Coin Cell offers a reliable, high‑capacity power solution for a wide range of small electronic devices. Its 3 V output, 135 mAh capacity, and compact size make it an excellent choice for manufacturers and consumers alike who demand long‑lasting performance in a lightweight package.

Frequently Asked Questions

• Can I use the CR2320 in devices that originally used 1.5 V batteries? Yes, many devices can accommodate a single 3 V cell instead of two 1.5 V cells, but always check the device’s voltage tolerance.
• Is the CR2320 rechargeable? No, it is a single‑use, non‑rechargeable lithium coin cell.
• What happens if I leave the battery in a device for an extended period? The low self‑discharge rate of lithium cells means minimal power loss over time; however, it’s best to replace batteries after 12–18 months of storage.
