Ultimate Guide to LR1130 Battery Equivalents

03 November 2025 153

The LR1130 battery is a small button cell. It is used in many everyday devices like watches, calculators, and toys.

Different brands use different names for the same battery size, finding the right battery LR1130 equivalent can be confusing.

This guide explains what the LR1130 battery is, its specifications, applications, and the best compatible equivalents.

You’ll also learn how to choose the right replacement, where to buy it, and how to handle and dispose of it safely.

What Is an LR1130 Battery?

The LR1130 battery is a 1.5-volt alkaline button cell. It is designed to power small, portable electronic devices. It is part of the LR series of alkaline batteries.

These batteries are known for their compact size and steady performance in low-drain applications.

The name “LR1130” is a standardized code used by the International Electrotechnical Commission (IEC), where:

“L” stands for alkaline electrolyte

“R” means round (cylindrical) shape

“1130” represents the battery’s dimensions — 11.6 mm in diameter and 3.1 mm in height.

This battery is commonly found in watches, calculators, laser pointers, toys, thermometers, and small electronic instruments.

It provides consistent voltage output, making it suitable for devices that require a stable power supply over time.

The LR1130 battery is often compared with the silver oxide battery in the same series. The SR1130 has the same physical size but offers longer life and more stable voltage.

Many manufacturers use their own naming conventions, the LR1130 can also be labeled as AG10, 389, LR54, or V10GA, depending on the brand.

You can safely interchange the 387A battery with LR1130 batteries in most devices. Because they share the same size and voltage.

The different labels reflect the naming conventions of different brands. The 387A performs well in low-drain or intermittent-use devices, such as digital thermometers, wristwatches, or small toys.

However, if your device requires longer life and more stable voltage output, consider using a silver oxide alternative such as SR1130, 389, or 390.

Silver Oxide Equivalents

Silver oxide batteries are a premium equivalent to LR1130 cells. They share the same physical dimensions but offer longer life, higher capacity, and more stable voltage (1.55V).

Therefore, they are more suitable for use in precision devices such as watches and medical instruments.

SR1130

The SR1130 battery is the silver oxide equivalent of the alkaline LR1130. It has the same size and shape, but with a more stable voltage (1.55V) and a longer lifespan.

So it is ideal for precision electronics that require consistent power. The “SR” in its name stands for Silver Oxide. While “1130” refers to its dimensions — 11.6 mm in diameter and 3.1 mm in height.

Size	11.6 mm × 3.1 mm	11.6 mm × 3.1 mm
Shelf Life	3–7 years	2–5 years
Common Use	Watches, cameras, medical devices, calculators	Watches, toys, small electronics

Difference Between 389 and 390

389 (Low-Drain Type): Best suited for devices that consume little power over long periods, such as watches and small measuring instruments.

390 (High-Drain Type): Designed for devices that need more power output, like digital cameras, thermometers, or other high-drain electronics.

Both versions can replace the LR1130 battery without issue. They are the same size and voltage compatible. The main difference lies in the power supply method.

The 389 model is suitable for long-duration, low-power applications, while the 390 model meets the needs of higher performance.

The 389/390 battery is a superior silver oxide alternative to the LR1130. These two batteries offer longer lifespan, more stable voltage, and better overall performance. They are suitable for a wide range of small electronic devices.

How to Choose the Right LR1130 Equivalent?

Choosing the right LR1130 equivalent battery ensures your device performs optimally and lasts longer. Here are the key factors to consider:

Check Your Device’s Requirements

Look at the battery compartment or the device manual for the recommended battery type.

Ensure the replacement matches the voltage (1.5V) and size (11.6 × 3.1 mm) of the original LR1130.

Decide Between Alkaline and Silver Oxide

Alkaline equivalents (AG10, LR54, 189, 387A):

Affordable and widely available

Suitable for low-drain devices like toys, calculators, or remotes

Voltage drops gradually over time

Silver oxide equivalents (SR1130, SR1130W/SW, 389/390):

Longer lifespan and more stable voltage

Ideal for precision devices like watches, medical instruments, or cameras

Slightly more expensive but worth it for critical devices

Consider Device Usage and Power Drain

High-drain or frequently used devices benefit from silver oxide equivalents.

Devices used occasionally or with low energy demands can rely on alkaline equivalents.

Brand Reliability and Shelf Life

Choose reputable brands (Duracell, Energizer, Panasonic, Maxell) for consistent performance.

Check the expiration date to ensure maximum shelf life.

Check Compatibility Names

Remember that LR1130 may also appear as: AG10, LR54, L1131, 189, 387A (alkaline); SR1130, SR1130W/SW, 389, 390 (silver oxide).

Safe Handling and Disposal of LR1130 Batteries

Even small button cells like the LR1130 require careful handling and proper disposal to avoid accidents, environmental damage, or device malfunction.

Safe Handling Tips

Avoid short-circuiting: Do not touch both ends of the battery with metal objects. Because it can cause sparks or leakage.

Keep dry and clean: Store in a dry place, away from moisture, to prevent corrosion or leakage.

Insert correctly: Match the positive (+) and negative (−) terminals with your device. Incorrect installation can damage the device.

Do not puncture or crush: Button cells can leak or even explode if physically damaged.

Keep away from children and pets: Small batteries are a choking hazard and can be extremely dangerous if swallowed.

Storage Tips

Store batteries in their original packaging or a battery case to prevent contact with other metal objects.

Avoid storing near heat sources, open flames, or direct sunlight.

Do not mix old and new batteries or different battery chemistries (alkaline vs silver oxide) in the same device.

Disposal Guidelines

Do not throw batteries in household trash: Button cells contain chemicals like manganese dioxide or silver oxide. They are harmful to the environment.

Use recycling programs: Many local electronics stores, municipal hazardous waste facilities, or battery collection points accept button cells for recycling.

Check local regulations: Some regions have specific rules for battery disposal—always follow them.

Environmental Considerations

Recycling reduces pollution and allows recovery of valuable metals.

Proper disposal prevents soil and water contamination.

The LR1130 battery powers many small devices like watches, toys, and calculators. Knowing its specifications and equivalent options (AG10, 189, SR1130) helps you pick the right replacement.

Buy from trusted retailers or local stores, handle batteries safely, and dispose of them properly to protect yourself and the environment.
