SR712SW 346 Battery Features and Specifications

SR712SW battery is button/coin cell battery, featuring physical dimensions (D x H) of 7.9 x 1.3 mm (~0.3110 x 0.05118 inches).

As said before, the SR712SW battery features silver-oxide chemistry, while alkaline chemistry is not in use - watches, thermometers, and similar devices require as stable as possible output voltage, hence, the alkaline 7.9 x 1.3 mm button/coin cell batteries are practically not in use.

Silver-oxide 7.9 x 1.3 mm battery's most common label is SR712 and SR712SW, but other labels are in use, including 346 battery, V346 (Varta 346 battery), 628 battery (Bulova), 280-66 (Citizen), 9949 (Omega), SB-AH (Seiko), etc.

All these batteries feature a nominal voltage of 1.55 volts, a cutoff voltage of 1.2 volts, and nominal capacity in the 9-10 mAh range.

Note: actual capacity depends on the battery's temperature, drain current, battery age, and similar.

Operating temperature is usually in the -10°C to +60°C range, and the annual self-discharge rate is 2-10% per year at room temperature, allowing these batteries to be stored 2-5 years, depending on the model.

The following comparison chart lists some of the most popular SR712SW silver-oxide batteries:

Of course, there are many other models on the market - when choosing "the best" SR712SW battery, go for the battery that fits your needs and requirements and which is easy to find, either locally or from the online shops.

Can I use a 346 battery as a substitute for an SR712SW?

Yes, you can use a 346 battery as a substitute for an SR712SW.

These are both low-drain, silver-oxide 7.9 x 1.3 mm button/coin-cell batteries - these batteries are equivalent and interchangeable, sharing the same voltage and physical dimensions.

They are commonly used in devices that require a compact, high-voltage battery, such as watches and other small electronic devices.

However, note that these are all "low drain" applications - for example, digital watches with alarms and LED lighting require larger, "high-drain" silver-oxide and even lithium batteries.

Note: Always ensure the replacement battery matches the specifications required by your device for optimal performance.

SR712SW Battery vs. SR716SW Battery

When comparing the SR712SW and SR716SW batteries, it's important to consider their specifications and suitable applications to understand their differences and similarities.

Voltage and Capacity

Both the SR712SW and SR716SW batteries operate at 1.55 volts, which is typical of silver oxide batteries used in precision devices. The primary difference lies in their capacity.

The SR712SW typically has a lower capacity, around 10 mAh, which is suitable for devices with lower energy demands.

On the other hand, the SR716SW offers a slightly higher capacity, generally about 21 mAh, which supports devices that require more power over a longer period.

Physical Dimensions

The physical size of these batteries is very important for compatibility with various devices.

The SR712SW battery measures 7.9 mm in diameter and 1.3 mm in height, making it very slim and suitable for ultra-compact devices.

The SR716SW is slightly different in size, typically measuring 7.9 mm in diameter and 1.65 mm in height, which is just a bit thicker, accommodating its higher capacity.

This difference in height doesn't sound much, but these batteries are intended to fit tightly in their battery compartments, so replacing, for example, an SR712SW with an SR716SW battery can lead to a deformed or permanently damaged battery compartment.

Applications

Due to their compact size and voltage output, both batteries are often used in small electronic devices.

The SR712SW is commonly found in ultra-thin watches, small medical devices, and other miniature electronics where space is at a premium.

The SR716SW, with its higher capacity, is also used in watches but can be more suitable for devices that are either used more frequently or require more power.

Availability and Equivalents

Both batteries have several equivalents and can generally be found under different manufacturer labels or generic numbers.

For instance, the SR716SW is also labeled as 315 battery, and finding a direct replacement is typically straightforward from various manufacturers.

SR712SW Battery Safety Issues

Modern SR712SW and similar button/coin cell batteries don't contain mercury, cadmium, and similar heavy metals which are toxic pollutants.

However, the SR712SW battery is a small and shiny object that can attract pets and small children and is easy to swallow.

Although materials found in the SR712SW battery are generally not toxic, if the battery gets swallowed, fluids in the body can short-circuit the battery, starting electrolysis, whose products can be rather harmful.

If SR712SW or any similar battery gets swallowed, contact the nearest emergency center immediately and act according to their instructions.

Long Story Short: If You are looking for a 7.9 x 1.3 mm button/coin battery, go for a silver-oxide SR712SW (346) battery from a reputable brand - such batteries have very stable voltage, can last for years and very often come in pets/kids-safe packages.

Some of the most popular models are (Amazon links, the links open in the new window):

• Energizer 346 SR712SW Silver Oxide Battery
• Renata 346 SR712SW Watch Battery
• Maxell SR712SW 346 Watch Battery

Although modern silver-oxide batteries generally don't contain dangerous chemicals and heavy elements, dispose of them properly.
