Issues with the CR1620 Battery Equivalent

While finding a suitable CR1620 battery equivalent can be convenient, there are several potential issues to be aware of:

• Compatibility Concerns:

  1. Voltage and Capacity Differences: Although many equivalents share the same voltage (3V), there may be slight variations in capacity (mAh). Ensure the replacement matches the original battery's capacity to avoid shortened device runtime.

  2. Physical Dimensions: Some equivalents might have minor differences in size, which can affect fitment in devices with very tight battery compartments.

• Brand Reliability:

  1. Quality Variations: Not all brands maintain the same quality standards. Low-cost or lesser-known brands might offer batteries that do not last as long or perform as reliably as those from reputable manufacturers.

  2. Leakage Risks: Inferior batteries may have a higher risk of leakage, which can damage the device they power.

• Shelf Life:

  1. Storage Stability: Some equivalents might not offer the same shelf life as the original CR1620. High-quality lithium coin cells typically have a shelf life of up to 10 years, but cheaper alternatives may degrade faster.

• Performance in Extreme Conditions:

  1. Temperature Sensitivity: Certain equivalents, especially those not specifically designed for extreme temperatures, may not perform well in very cold or hot environments. For example, BR1620 batteries are often better suited for high-temperature conditions due to their chemical composition.

• Availability and Authenticity:

  1. Counterfeit Products: The market for small batteries is rife with counterfeits. Ensure you purchase from reputable sellers to avoid counterfeit batteries, which can pose safety risks and offer poor performance.

  2. Supply Issues: Some equivalents might be harder to find depending on your location, leading to delays or higher costs.

• Application-Specific Requirements:

  1. Device Sensitivity: Some devices may be more sensitive to variations in battery specifications. High-precision devices like medical instruments may require specific brands or types to function correctly and safely.

​Can I replace CR1616 with CR1620

Yes, you can often replace a CR1616 battery with a CR1620, as both share the same diameter (16.0 mm). 
However, the CR1620 is thicker (2.0 mm vs. 1.6 mm), so ensure it fits securely in the device without causing damage. 
The CR1620 typically has a higher capacity, potentially leading to longer battery life, but this advantage depends on whether the device is designed to utilize the extra capacity. Additionally, CR1620 batteries may support higher maximum drain/pulse currents, so verify that your device’s specifications align with the CR1620's capabilities before making the switch.

Is a CR1620 battery the same as CR2016

No, a CR1620 battery is not the same as a CR2016 battery. While they may appear similar and have similar names, they have different specifications, including their size and capacity.

• CR1620 Battery:

  1. Size: 16mm diameter, 2.0mm thickness

  2. Capacity: Typically around 70-75 mAh

  3. Voltage: 3 volts

• CR2016 Battery:

  1. Size: 20mm diameter, 1.6mm thickness

  2. Capacity: Typically around 90-100 mAh

  3. Voltage: 3 volts

As you can see, while both batteries have a 3-volt voltage rating, they differ in size and capacity. 

Therefore, they are not interchangeable, and using one in place of the other could result in improper fitment or insufficient power for the device. 

Always use the correct battery type recommended by the device manufacturer.

Final Verdict

When seeking CR1620 battery equivalents, it's essential to consider various factors such as compatibility, reliability, and availability. 

While several alternatives exist, including DL1620, ECR1620, BR1620, 5009LC, L08, and KCR1620, each offers slightly different specifications and features. 

Ensuring the chosen equivalent matches the voltage, capacity, and physical dimensions of the original CR1620 battery is crucial for proper device function. 

Whether purchasing from local retailers, online platforms like Amazon and eBay, or specialized battery stores such as Batteries Plus Bulbs, always prioritize reputable sellers and verify compatibility with your device. 

By doing so, you can confidently select the right CR1620 battery equivalent for your needs, ensuring reliable power for your electronic devices.
