CR1632 vs. CR2032

CR1632 and CR2032 batteries are similar in many aspects, including their voltage, lack of mercury, long shelf life, and suitability for a wide range of temperatures. However, they differ in their nominal capacity, size, and specific applications. It's important to note that these batteries are not interchangeable due to their size differences.

CR1632 vs. CR1620

Ultimately, the choice between CR1632 and CR1620 batteries depends on the specific device and its power requirements. If you need a long-lasting battery with higher power output, CR1632 is the better option. If you are on a budget or need a thinner battery, CR1620 may be more suitable.

Is CR1632 Rechargeable?

No, the CR1632 is not a rechargeable battery. Attempting to charge a non-rechargeable battery can lead to leakage, overheating, or even explosion, posing a risk of damage to your device and serious injury. When the battery is depleted, it should be replaced.

Is CR2032 and CR1632 Interchangeable?

No, the CR1632 and CR2016 batteries are not interchangeable because the CR2016 is wider than the CR1632. The CR2016 has a diameter of 20 mm and a thickness of 1.6 mm, while the CR1632 has a diameter of 16 mm and a thickness of 3.2 mm.

What is the Life Expectancy of a CR1632 Battery?

The lifespan of a CR1632 or any other battery depends on several factors, including operating temperature, load dynamics, and self-discharge current. For example, let's consider a CR1632 operating at room temperature with a capacity of 130mAh. If we apply an average load of 15k ohms, the battery will last for 1 hour when drawing 130mA. At 65mA, the battery will last for 2 hours, and at 10mA, it will last for 13 hours.

However, these batteries are typically used in small devices that do not constantly drain the battery. For instance, most electronic toys use around 0.19mA, which would provide a lifespan of approximately 684 hours of continuous use from a 130mAh battery.

To estimate a battery's lifetime, you can divide the battery capacity by the load. This calculation provides an estimate based on constant or regular conditions.

Internal Resistance Characteristics

Another important factor to consider is the internal resistance of a battery, which refers to the resistance the battery provides against power drain during use. While all batteries have internal resistance, it is typically low in new batteries. However, external environmental factors can increase internal resistance over time and with use.

Low internal resistance allows for greater power drain from the battery, whereas high internal resistance results in less current drain from the source.

Safety Precautions While Using the Battery

• Keep out of reach of children.
• Ensure the battery compartment design is child-resistant.
• Please avoid using the batteries in extremely heated environments or throwing them into a fire, as this can cause discharge or explosion.
• Discontinue use if leakage or discoloration is detected.
• Remove batteries from devices not in use for long periods.
• Do not drop or hit the battery, as this can cause leakage or explosion.
• Avoid using batteries beyond their expiry date, as they may leak and damage the electronic device.

Conclusion

The CR1632 is a widely used battery type found in many electronic devices. Due to its compatibility with a wide range of gadgets, finding suitable CR1632 battery equivalents is crucial for maintaining the functionality of various devices.
