Finding the right SR920SW battery equivalent can be overwhelming. Button cell batteries, particularly watch batteries, come with different names and brands. If you’re looking for a replacement, this article will show you the battery equivalents and alternatives of SR920SW to help you meet the right battery for your device.
What is a SR920SW battery?
SR920SW is a silver oxide battery with a metal button shape. It is typically used for small devices like analog wrist watches, basic calculators, and hearing aids. Silver oxide batteries can be categorized as high-drain or low-drain batteries.
SR920SW is an example of a low-drain battery. Low-drain cell batteries are used for devices that don’t require too much power such as analog wrist watches. On the other hand, high-drain cell batteries are used for power-hungry devices such as digital watches.
What Are SR920SW Battery Equivalents?
The battery equivalents are another names created by brands and organizations for SR920SW. SR920 battery equivalents have 1.55 volts, a size of 9.5 x 2.1 mm, and a silver oxide (SR) chemistry. However, some equivalents have a different chemistry such as alkaline (LR).
The “SR” prefix in SR920SW refers to silver oxide. The digits typically represent the size of the cell battery. For instance, the 920 in SR920SW means its size is around 9.5 mm in diameter and 2.1 mm in height. The “SW” suffix means it is a low-drain battery and “W” if it is a high-drain battery.
List of SR920SW Battery Equivalents
Below are the other names of SR920SW based on the SR920SW battery equivalent chart. These equivalents can be high-draining or low-draining batteries with silver oxide or alkaline chemistry.
371
371 is a low-drain cell battery with 1.55 volts and a size of 9.5 x 2.01 mm. It is the most common alternative name used by different watch brands for SR920SW battery. For instance, 371 is the Maxell SR920SW battery equivalent while D371 is the SR920SW battery Duracell equivalent.
370
370 is a silver oxide battery used for power-hungry devices such as watches with backlight and alarm. Like 371, it can power up to 1.55 volts at a size of 9.5 x 2.01 mm. Although SR920SW is a low-drain battery, 370 as a high-drain battery is a qualified replacement for SR920SW.
SR920W
SR920W is the high-power requirement version of SR920SW. It provide less discharging stability to devices than SR920SW. This battery code is also the Sony SR920SW battery equivalent and Maxell SR920SW battery equivalent – the two popular brands that use SR920W.
AG6
AG6 is a button cell battery with alkaline chemistry. Alkaline batteries have the same voltage and size as silver oxide batteries, making AG6 a qualified SR920SW battery equivalent. AG6 is a power-hungry battery and is less consistent in discharging power to devices.
LR920
LR920 is another alkaline name for SR920SW battery. Like AG6, it is a qualified SR920SW battery equivalent among alkaline batteries. Alkaline batteries like LR920 has shorter life span than silver oxide equivalents of SR920SW.
SB-AN
SB-AN is the Seiko SR920SW battery equivalent. Seiko is the only brand who use SB-AN as equivalent of SR920SW. SB-AN battery has 1.5 volts and size of 9.5 x 2.1 mm. It is a low-drain battery with silver oxide chemistry.
605
605 is the SR920SW battery equivalent by Bulova brand – a trusted maker of watch batteries from Europe. Like SR920SW, this battery name is for devices with stable power requirement. 605 is a silver oxide battery with the same volts and size as SR920SW.
280-31
280-31 is a SR920SW battery equivalent that is unique only for Citizen batteries – a trusted battery brand from Asia. It is a low-drain cell battery with silver oxide chemistry. 280-31 has the same size and voltage as SR920SW, making it a qualified replacement.
SR69
SR69 is the SR920SW battery equivalent set by the International Electro Technical Commission (IEC) for button shape batteries with silver oxide chemistry. SR69 has 1.5 volts, a 9.5 mm diameter, and 2.1 mm height. Brands like Varta use this code as equivalent for SR920SW.
Conclusion
SR920SW battery equivalents have many names, depending on the brand. However, they all share the same size and voltage. The low-drain silver oxide batteries are 371, SB-AN, 605, and 280-31. The high-drain silver oxide batteries are 370 and SR920W. For alkaline batteries, AG6 and LR920 are the equivalents for SR920SW.

Frequently Asked Questions
Are SR920SW and SR920W the same?
No, they’re not the same. SR920SW is a low-drain cell battery used for devices with low power demand such as an analog wristwatch. SR920W is a high-drain cell battery used for devices with high power demand such as a digital watch with backlight and alarm. However, they’re both silver oxide batteries with the same voltage and size.
Are 371 and 370 the same?
371 battery is a low-drain battery, used for providing stable support to devices for long-term use. On the other hand, 370 battery is a high-drain battery, used for power-hungry devices. However, both of them can replace SR920SW battery as they have the same voltage and size.
Are silver oxide and alkaline the same?
No. Silver oxide have low-drain and high-drain batteries. The low-drain SR batteries releases a stable amount of power, enabling devices to last longer. Alkaline (LR/AG) batteries are all high-drain batteries, meaning, they are less stable and would drain the devices faster.
