What battery is equivalent to a CR1620

The ML1620 battery is indeed an equivalent rechargeable alternative to the non-rechargeable CR1620 battery. Here's a comparison between the two:


Type:


CR1620: Non-rechargeable lithium manganese-dioxide battery

ML1620: Rechargeable lithium manganese-dioxide battery

Nominal Voltage:


Both CR1620 and ML1620 have a nominal voltage of 3.0 volts.


Capacity:


CR1620: Typically around 65-80 mAh (nominal capacity)

ML1620: Capacities may vary, but generally similar to or slightly higher than CR1620


Rechargeability:


CR1620: Non-rechargeable; meant for single-use applications

ML1620: Rechargeable; can be recharged multiple times using appropriate charging equipment


While the ML1620 can replace the CR1620 in many applications, it's important to note that the ML1620's physical dimensions may not be identical to the CR1620. Therefore, compatibility with the device's battery compartment size should be verified before substitution. Additionally, the ML1620's rechargeable nature may require specific charging equipment and considerations regarding charging cycles and voltage management.

Is a CR1620 battery the same as CR2016

No, a CR1620 battery is not the same as a CR2016 battery. While both are coin cell batteries and share similarities in their naming conventions, they differ in size and thickness:


Size:

CR1620: 16.0 mm in diameter

CR2016: 20.0 mm in diameter


Thickness:

CR1620: 2.0 mm thick

CR2016: 1.6 mm thick


CR1620 is smaller in diameter but thicker compared to the CR2016. Therefore, they are not interchangeable in devices due to differences in physical dimensions. It's essential to use the correct battery size and type as specified by the device manufacturer to ensure proper operation and fit within the battery compartment.




Are 2032 and 1620 batteries the same

No, a CR1620 battery is not the same as a CR2032 battery. While both are coin cell batteries and share similarities in their naming conventions, they differ in size and thickness:


Size:


CR1620: 16.0 mm in diameter, 2.0 mm thick

CR2032: 20.0 mm in diameter, 3.2 mm thick

Capacity:


CR1620: Typically around 65-80 mAh (nominal capacity)

CR2032: Typically around 200-240 mAh (nominal capacity)


CR2032 is larger in both diameter and thickness compared to the CR1620. Therefore, they are not interchangeable in devices due to differences in physical dimensions. It's essential to use the correct battery size and type as specified by the device manufacturer to ensure proper operation and fit within the battery compartment.


Can I use a CR1632 instead of CR1620

While the CR1632 battery shares similarities with the CR1620 in terms of voltage and appearance, there are important differences in their physical dimensions and capacity:


Size:


CR1620: 16.0 mm in diameter, 2.0 mm thick

CR1632: 16.0 mm in diameter, 3.2 mm thick


Capacity:


CR1620: Typically around 65-80 mAh (nominal capacity)

CR1632: Typically around 120-140 mAh (nominal capacity)


While both batteries have the same diameter, the CR1632 is thicker than the CR1620. Therefore, using a CR1632 instead of a CR1620 may result in fitting issues in devices with tight battery compartments. Additionally, while the CR1632 has a higher capacity compared to the CR1620, it may not provide optimal performance in devices designed specifically for CR1620 batteries.


In some cases, if the device allows for slight variations in battery size and has sufficient space to accommodate the thicker CR1632, it might work as a temporary replacement. However, it's always recommended to use the correct battery size and type as specified by the device manufacturer to ensure proper operation and avoid potential damage or malfunction.




Are CR2016 and CR2032 interchangeable

CR2016 and CR2032 batteries are not interchangeable due to several reasons:


Physical Size Differences: CR2016 batteries are thinner (1.6 mm) than CR2032 batteries (3.2 mm), despite having the same diameter (20 mm). This difference in thickness may prevent proper fitting or cause damage to the device if the wrong size is used.


Voltage Differences: CR2016 batteries typically have a nominal voltage of 3 volts, just like CR2032 batteries. However, if you stack up two CR2016 batteries to replace a CR2032, you would indeed have a total voltage of 6 volts, which is double the voltage required for the device. This can lead to damage or malfunction of the device's electronics.


Designated Usage: Manufacturers designate specific battery models for different devices based on their voltage, capacity, and size requirements. Using a different battery model than what is specified by the manufacturer can compromise the device's performance, lifespan, and safety.


Therefore, it's essential to use the correct battery size and type as specified by the device manufacturer to ensure proper operation and avoid potential damage or safety hazards.



Can I use CR2032 instead of CR2016 in key fob

While it's true that CR2032 batteries have a higher capacity than CR2016 batteries and may fit into some devices despite being thicker, it's important to exercise caution when substituting one battery type for another. 


Physical Fit: Although CR2032 batteries are thicker than CR2016 batteries, some devices may still accommodate the larger size. However, it's essential to ensure that the thicker battery fits securely within the battery compartment without causing any damage to the device.


Voltage Compatibility: Both CR2016 and CR2032 batteries typically have a nominal voltage of 3 volts. However, as previously mentioned, stacking two CR2016 batteries to replace a CR2032 would result in a total voltage of 6 volts, which could damage the device. Therefore, if a CR2032 fits and is used as a replacement for a CR2016, it should provide the correct voltage without any issues.


Longevity: Due to its higher capacity, a CR2032 battery may indeed last longer than a CR2016 battery when used in the same device. This can be advantageous in applications where battery life is critical, such as key fobs.

Can I replace CR1616 with CR1620

Yes, you can physically replace a CR1616 battery with a CR1620 battery in many cases, as they share the same diameter (16.0 mm). However, it's important to consider the following factors before doing so:


Thickness: CR1620 batteries are thicker (2.0 mm) than CR1616 batteries (1.6 mm). While many devices can accommodate the slightly thicker battery, it's essential to ensure that the CR1620 fits securely within the battery compartment without causing any damage to the device.


Capacity: CR1620 batteries typically have a higher capacity than CR1616 batteries. Replacing a CR1616 with a CR1620 may result in longer battery life in some cases. However, it's important to note that using a battery with a higher capacity does not necessarily guarantee better performance if the device's electronics are not designed to take advantage of the extra capacity.


Maximum Drain/Pulse Currents: CR1620 batteries may have slightly higher maximum drain/pulse currents compared to CR1616 batteries. While this may not be a significant issue for many devices, it's essential to consider whether the device's specifications and requirements align with the capabilities of the CR1620 battery.


What is the minimum voltage for CR1620

The cutoff voltage for a CR1620 battery is typically 2.0 volts. This cutoff voltage is considered the minimum allowable voltage, below which the battery is considered depleted or empty.


While the nominal voltage of a CR1620 battery is 3.0 volts, its voltage decreases gradually as it discharges. When the battery's voltage reaches or drops below the cutoff voltage of 2.0 volts, it is no longer able to provide sufficient power for most devices and is considered to have reached the end of its usable life.

What's the difference between a CR1616 and an CR1620

Size:

Both CR1616 and CR1620 batteries have the same diameter of 16mm, denoted by the first two digits of their names.

The difference lies in their thickness: CR1616 batteries are 1.6mm thick, while CR1620 batteries are 2.0mm thick. The last two digits represent the thickness in tenths of millimeters.


Compatibility:

While CR1616 and CR1620 batteries have the same diameter, their difference in thickness can impact compatibility.

CR1620 batteries may not fit properly in devices designed for CR1616 batteries. Attempting to use a thicker battery may result in the battery compartment lid not closing securely or the battery contacts being distorted, which could affect the device's functionality.


Capacity:

Generally, CR1620 batteries have a higher capacity compared to CR1616 batteries due to their larger size. This means CR1620 batteries may last longer in devices with similar power requirements.

What is the lifespan of a CR2016 battery

About ten years.
