CR2016 vs CR1620: Does a CR2016 Replace a CR1620 Battery? Compatibility Explained

The CR2016 battery cannot replace a CR1620 battery. The CR1620 is thicker but has a smaller diameter than the CR2016. These differences in battery dimensions make them incompatible with the same devices. Always verify the specifications for compatibility before replacing batteries.

A CR2016 can replace a CR1620 in devices that have sufficient space to accommodate the extra thickness. However, using a CR2016 in a device designed specifically for a CR1620 may lead to fitting issues, potential damage, or malfunction. It is essential to check your device’s specifications before substituting one for the other.

Both batteries share the same diameter of 20 mm and offer the same voltage of 3 volts. Therefore, in terms of electrical performance, they are compatible as long as the physical dimensions are taken into account.

When considering replacements for your device, the size and fit of the battery must be your primary concern. Understanding these specifications helps ensure optimal functionality. Moving forward, we will explore alternative batteries and their compatibility with your devices, providing a broader perspective on battery selection.

Are CR2016 and CR1620 Batteries the Same?

The CR2016 and CR1620 batteries are not the same. They differ in thickness, affecting their compatibility in devices. The CR2016 battery is 2.0 mm thick, while the CR1620 battery is 1.6 mm thick. Therefore, a CR2016 cannot replace a CR1620 in all situations due to this difference in size.

Both batteries share the same diameter of 20 mm and have a nominal voltage of 3 volts. They also have similar chemistry, typically lithium. However, the thickness difference means that a CR2016 is slightly heavier and has a longer life expectancy due to its increased capacity. Consequently, devices designed for CR1620 batteries may not accommodate the thicker CR2016 battery.

One advantage of using CR2016 batteries is their longer battery life. Devices that can accommodate both batteries might benefit from this extended duration of power, allowing for prolonged use without frequent replacements. A CR2016 battery can deliver about 90 mAh of energy, while a CR1620 generally provides around 75 mAh. This translates to less frequent battery changes, which can be more convenient for the user.

On the downside, using a CR2016 battery in a device designed for a CR1620 can lead to fit issues. Incompatibility may cause physical damage to the device or prevent it from functioning correctly. Some manufacturers recommend using only the specified battery type to ensure optimal performance. For this reason, always check the manufacturer’s guidelines before substituting one battery for another.

In summary, if you are considering a battery replacement, verify your device’s specifications first. If it requires a CR1620, do not use a CR2016 despite its longer life. If your device can accommodate both, prefer the CR2016 for longer usage. Always adhere to manufacturer recommendations for safe and effective operation.
