CR1632 and CR1620 batteries are both button cell batteries. They are both used in watches, calculators, and other small electronic devices. CR1632 batteries are 3 volts and have a capacity of 220 mAh, while CR1620 batteries are 2 volts and have a capacity of 150 mAh. 

CR1632 batteries will last longer than CR1620 batteries in these devices. The CR1620 battery is also a coin cell battery, but it is 20mm in diameter and 2mm thick. Both batteries have a capacity of 85mAh. The CR1632 battery has a higher discharge current of 0.

Well, it really depends on what you need it for. If you need a battery for something that requires a lot of power, like a remote control, then the CR1632 is the way to go. Both of these batteries have their own benefits and drawbacks that should be considered before making a purchase.

CR1632 Battery: What is It?

Silver oxide batteries, also known as CR1632 coins, are lithium-ion 3V coin cells. It has a diameter of 16mm and a height of 3.2mm, making it a small round battery. Additionally, it weighs only two grams.

Many applications use CR1632 batteries, such as clocks, calculators, hearing aids, and toys. Other vehicles requiring a backup power source for critical electronic devices may also use them in emergency lighting systems, such as aircraft, spacecraft, submarines, and trucks.

Standard and high-capacity Cr1632 batteries are available in two physical sizes. High-capacity cr1632 batteries have twice the capacity of standard-size cr1632 batteries. They have a capacity of 160mAh, which is twice the capacity of standard-size cr1632 batteries.

CR1620 Battery: What is It?

There’s another coin battery, but it’s not quite as popular as the cr1632. As well as being known as a silver oxide battery, it is a lithium 3V coin cell battery. Approximately 16mm in diameter and 2.0mm in height, it is a small round battery. 

There is also only 1 gram of weight to it. Among the many uses of Cr1620 batteries are toys, small electronic devices, calculators, and hearing aids. There is one difference between the cr1632 and 1632, namely that the cr1632 is 0.2mm higher than 1632. 

You must make sure that your 1632 battery has 0.2mm more height than the original one if you want to fit it into an electronic device that requires a 1632 battery, otherwise, it will not fit.

CR1632 vs CR1620 Batteries: Which is Better?

CR1632 vs CR1620 Batteries

CR1632 and CR1620 batteries are both coin cell batteries. They are both 3 volts and have a diameter of 16 mm. The CR1632 battery is a little thicker than the CR1620 battery. So, which is better?

The CR1632 battery has a capacity of 225 mAh, while the CR1620 battery only has 150 mAh. This means that the CR1632 battery will last longer than the CR1620 battery. The CR1632 battery also has a higher discharge rate, so it can power devices that require more power.

The CR1620 battery is cheaper than the CR1632 battery. So, if you are on a budget, the CR1620 may be a better option for you. However, if you need a long-lasting and powerful battery, the CR1632 is the better choice.

Which Battery Lasts Longer: CR1632 or CR1620?

CR1632 and CR1620 batteries are both coin-shaped button batteries that are commonly used in small electronics. These batteries are very similar in size and voltage, but there are some key differences that can affect their lifespan.

CR1632 batteries have a higher capacity than CR1620 batteries, meaning they can last up to twice as long. However, CR1620 batteries have a higher discharge rate, so they may be better suited for devices that require frequent or high power usage.

Ultimately, the battery that will last longer will depend on the specific device and how it is used. A CR1632 battery may last longer in a device with low power requirements, while a CR1620 battery may be better suited for a device with high power needs.


In conclusion, CR1632 and CR1620 batteries are both viable options for use in a number of devices. CR1632 batteries tend to have a longer lifespan and can be used in a wider range of temperatures, while CR1620 batteries may be a better option in terms of cost. As always, it is important to consult your device’s manual to determine which type of battery it requires.
