What is the difference between 371 and 370?

The primary distinction between the 371 and 370 batteries lies in their chemical composition and intended applications. The 371 battery is characterized by its silver oxide chemistry and is designated as "high drain." It is well-suited for watches with features demanding higher power consumption, such as those with alarms, backlit screens, or chronographs. Due to its ability to deliver higher current, the 371 battery is optimal for devices with intermittent high power demands. On the other hand, the 370 battery utilizes alkaline chemistry and is not specifically categorized as "high drain." It is generally suitable for devices with lower to moderate power requirements, providing a reliable and consistent power output. Despite both batteries having similar nominal capacities, their chemical makeup determines their effectiveness in different types of electronic devices.

What size is SR920SW?

The SR920SW is a button cell battery with a standardized size of approximately 9.5mm in diameter and 2.0mm in height.

What does SW mean on a battery?

In the context of battery designations, the "SW" suffix typically indicates that the battery is designed for use in low-drain devices. On the other hand, a designation without the "SW" (e.g., "W") may indicate that the battery is intended for high-drain devices. This differentiation is particularly common in the Silver Oxide range of batteries.

Can I use a 395 battery instead of a 371?

While the 395 and 371 batteries share the same diameter (approximately 9.5mm), the key difference lies in their thickness. The 395 battery is thicker than the 371. In some cases, a 395 battery might physically fit into a compartment designed for a 371 battery. It seems that in certain watch models (ETA 955.114 from 1988 onwards), the 395 battery can be used instead of the 371, but the 371 is the recommended and correct choice. However, in the same series of watches from 1983 to 1986 (ETA 555.115) and 1992 onwards (ETA 955 series), both the 371 and 395 batteries will fit, but the thinner 371 may be more prone to coming loose.

Can I replace SR621SW with SR626SW?

While the SR621SW and SR626SW have the same width, the SR626SW is slightly taller than the SR621SW. The height difference can be a potential issue, especially in watches that are secured from the top or have both top and bottom contacts. If the watch is designed to accommodate both SR621SW and SR626SW batteries, and there is sufficient space for the taller SR626SW without causing contact or fitting issues, it may be possible to use the SR626SW as a replacement. However, it's essential to consider the specific design and compatibility of your watch.

Is SR621 the same as SR621SW?

Yes, SR621 and SR621SW typically refer to the same type of battery, specifically a silver oxide button cell battery. The "SW" in SR621SW stands for "Silver Oxide," and it is commonly used in watches, small electronic devices, and other gadgets. The additional labels you mentioned, such as SR60, 164, 364, SG1, and AG1, are also alternative designations for this type of battery. These batteries generally have a nominal voltage of 1.55 volts and a cut-off voltage of 1.2 volts. The different labels may be used interchangeably, and the choice of label often depends on the manufacturer or brand.

Is battery 364 the same as SR621SW?

Yes, the battery size 364 is equivalent to the SR621SW. In this case, the Energizer 364/363 Watch Battery is described as a silver oxide replacement for various common watch battery sizes, including 364, 363, AG1, and SR621SW. This means that you can use the Energizer 364/363 battery as a substitute for SR621SW in watches and other devices that require a battery of this size.

Are 370 and 371 batteries the same

The 370 and 371 batteries share a similar physical size but are designed for distinct applications with varying power demands. The 370 is intended for high-drain devices such as watches with alarms and chronographs, delivering higher energy output in short bursts. On the other hand, the 371 is designed for low-drain applications, ideal for basic timekeeping watches, providing a more consistent and moderate energy output over an extended period. While theoretically interchangeable in watches of the same size, using the wrong type may lead to shorter battery life.

Are SR920W and SR920SW the same

SR920W and SR920SW batteries share the same physical size but are designed for different drain applications. The SR920W is a high-drain battery, while the SR920SW is a low-drain battery.

Regarding the SR920 (370) and 371 batteries, they are generally interchangeable due to their similar physical dimensions. However, it's important to note that the SR920 (370) is designed for high-drain applications, while the SR920SW (371) is intended for low-drain devices. While you can replace an SR920 (370) with an SR920SW (371), it may result in a slightly shorter runtime because the 371 battery is optimized for lower power consumption.
