batteries cr 2016 are suitable for low-power devices, while CR2025 batteries are better suited for devices that require more power and longer battery life.


Rechargeability Differences between CR2016 and CR2025 Batteries

When comparing the CR2016 and CR2025 batteries in terms of rechargeability, it's important to note that both of these batteries are primary (non-rechargeable) lithium batteries. Recharging them is not intended for them, and trying to do so can be risky.

Primary lithium batteries are intended for one-time usage, such as the CR2016 and CR2025. They are not equipped with the necessary chemistry or construction to safely handle the charging process. Attempting to recharge these batteries can lead to overheating, leakage, or even rupture, posing a risk of fire or injury.

In summary, neither the CR2016 nor the CR2025 battery is rechargeable. They ought to be disposed of correctly after usage as they are designed for one-time use only.


Comparators for the CR2016 and CR2025 Batteries

CR2016 and CR2025 batteries are not interchangeable due to their different sizes and capacities. However, there are equivalent batteries that can be used as substitutes based on their dimensions and voltage. Here are some common equivalents:

1. CR2032: This battery is thicker than both the CR2016 and CR2025, but it has the same diameter and voltage. It can be used as a substitute if the device can accommodate the slightly larger size.

2. LR44/A76: While not a direct substitute in terms of size, the LR44 or A76 battery shares the same voltage (1.5V) as the CR2016 and CR2025. It can be used in some devices that accept the CR2016 or CR2025, but size and capacity differences may affect performance and fit.

3. CR1616: This battery is thinner than the CR2016 and CR2025, but it has the same diameter. It can be used in devices that require a thinner battery, but its lower capacity may result in shorter battery life.

4. LR41: Similar to the LR44/A76, the LR41 battery has the same voltage (1.5V) but differs in size. It can be used in some devices that accept the CR2016 or CR2025, but fit and performance may vary.

It is crucial to verify the specifications and needs of the device before replacing the batteries in order to guarantee compatibility and best possible performance.


Is it possible to swap out CR2016 and CR2025 batteries?

Because CR2016 and CR2025 batteries differ in size and thickness, they cannot be used interchangeably. Although they both have a 20mm diameter, the CR2016 and CR2025 have different thicknesses of 1.6 and 2.5 mm, respectively. This difference in thickness means that the CR2025 may not fit into devices designed for the CR2016, and vice versa.

To guarantee good fit and operation, it's crucial to utilize the battery size that the device manufacturer specifies. When an unsuitable battery is used, the device may malfunction, sustain damage, or even pose a risk to safety.



In conclusion, CR2016 and CR2025 batteries are similar in many ways, including their diameter and voltage. However, they differ in thickness and capacity, which can affect their interchangeability and suitability for different devices.

- CR2016 batteries work well with devices that need a small, low-power battery since they are thinner and have a lower capacity.

- Devices with higher energy demands or longer runtime requirements can benefit from the thicker and larger capacity of CR2025 batteries.

Although CR2016 and CR2025 batteries can occasionally be used interchangeably, it's important to take your device's unique requirements into account. For the best performance and compatibility, make sure you are using the appropriate battery type by always checking the device's specifications or speaking with the manufacturer.
