Can You Replace a CR1616 Battery with a CR1620?
You can replace a CR1616 battery with a CR1620 in some cases, but it’s important to understand their differences. Both batteries share the same diameter but differ in thickness, which can impact compatibility with certain devices. This article will explore the specifications, performance, and considerations for using these batteries interchangeably.
What are the key differences between CR1616 and CR1620 batteries?
The primary differences between CR1616 and CR1620 batteries lie in their thickness and capacity:
- CR1616: Measures 16 mm in diameter and 1.6 mm in thickness, typically has a capacity of 50 to 70 mAh.
- CR1620: Also measures 16 mm in diameter but is thicker at 2.0 mm, with a higher capacity ranging from 65 to 80 mAh.
Chart: Comparison of CR1616 and CR1620 Batteries
| Specification | CR1616 | CR1620 |
|---|---|---|
| Diameter | 16 mm | 16 mm |
| Thickness | 1.6 mm | 2.0 mm |
| Capacity | 50 – 70 mAh | 65 – 80 mAh |
| Voltage | 3V | 3V |
How do the dimensions of CR1616 and CR1620 batteries affect compatibility?
While both batteries have the same diameter, the difference in thickness can affect how they fit into devices:
- CR1616 Fit: Devices designed for the thinner CR1616 may not accommodate the thicker CR1620 without issues.
- Battery Compartment: If the battery compartment is tight, using a thicker battery could prevent proper closure or even damage the device.
What are the performance characteristics of CR1616 compared to CR1620?
In terms of performance:
- Capacity Differences: The CR1620 generally provides longer life due to its higher capacity, making it suitable for devices that require more power.
- Pulse Current: The higher capacity of the CR1620 allows it to handle higher pulse currents better than the CR1616, which may be beneficial for devices that demand more energy during operation.
Are there specific devices where replacing CR1616 with CR1620 is advisable?
Replacing a CR1616 with a CR1620 may be advisable if:
- The device can physically accommodate the thicker battery without issues.
- You need longer battery life, as the higher capacity of the CR1620 can provide extended usage time.
However, if the device is designed specifically for the CR1616, it’s best to stick with that specification to avoid potential problems.
What should you consider before replacing a battery in your device?
Before replacing a battery, consider these factors:
- Device Specifications: Always check your device’s manual or specifications to confirm compatible battery types.
- Fitment: Ensure that there is enough space in the battery compartment for the thicker battery.
- Performance Needs: Consider whether your device will benefit from the increased capacity provided by the CR1620.
