When it comes to small button cell batteries, the LR44 is one of the most commonly used options. These batteries are widely found in devices like calculators, watches, toys, hearing aids, and small electronics. However, due to the variety of battery brands and designs available, you may find yourself needing a suitable replacement for your LR44 battery. In this article, we’ll delve into the top picks for LR44 battery equivalents, provide a comprehensive comparison, and help you make an informed decision when choosing the right battery for your needs.
What Is an LR44 Battery?
Before we get into the equivalents, let’s first understand what an LR44 battery is. The LR44 is a 1.5V alkaline button cell battery with a diameter of 11.6mm and a height of 5.4mm. It is often used in low-drain devices and offers a reliable power source for gadgets that don't require high power consumption. Some devices may need a specific type of battery due to size, voltage, or other technical reasons, and in such cases, finding the right equivalent is crucial.
Common LR44 Battery Equivalents
Several brands and types of batteries can serve as replacements for the LR44. These equivalents typically share the same size, voltage, and power specifications, but their chemical composition or brand may vary. Let’s look at the most common LR44 equivalents and how they compare.
1. AG13

2. 357
- Voltage: 1.55V
- Chemistry: Silver Oxide
- Uses: Common in watches and high-precision instruments.
- Details: While the LR44 is an alkaline battery, the 357 is a silver oxide variant, which offers a slightly higher voltage and longer-lasting power, making it suitable for devices that require more consistent voltage output.
3. SR44
- Voltage: 1.55V
- Chemistry: Silver Oxide
- Uses: Watches, cameras, and medical devices.
- Details: The SR44 is another silver oxide battery that is often used as a direct replacement for the LR44. The silver oxide chemistry provides a more stable voltage output over time, but it usually costs more than the LR44.
4. LR1154
- Voltage: 1.5V
- Chemistry: Alkaline
- Uses: Similar to LR44, used in small electronics, medical devices, and toys.
- Details: The LR1154 is often marketed as an LR44 equivalent. Its size and power capacity match the LR44, making it an ideal replacement.
5. A76
- Voltage: 1.5V
- Chemistry: Alkaline
- Uses: Toys, calculators, medical devices, and small gadgets.
- Details: The A76 is very similar to the LR44, with both being 1.5V alkaline batteries. It’s often sold as an equivalent to LR44, and their performance is virtually identical in many applications.
6. V13GA
- Voltage: 1.5V
- Chemistry: Alkaline
- Uses: Used in a variety of devices including remote controls, toys, and small electronics.
- Details: The V13GA is an alkaline battery that can be used as an LR44 equivalent. It offers good performance in low-power devices and is often available at a lower price point than other silver oxide alternatives.

How to Choose the Right LR44 Equivalent
When choosing an LR44 equivalent, several factors should be taken into consideration. Here's a breakdown of what to keep in mind:
1. Voltage Compatibility
The LR44 has a nominal voltage of 1.5V, and most of its equivalents have the same voltage. However, some, such as the 357 or SR44, provide a slightly higher voltage (1.55V). Although this difference is minimal, it can affect devices that are particularly sensitive to voltage variations, like precision instruments. If your device specifies a 1.5V battery, sticking with an LR44 or its direct equivalent may be the best choice.
2. Chemistry and Longevity
The primary difference between LR44 and many of its equivalents (such as the SR44 or 357) lies in the chemistry. Alkaline batteries like the LR44 tend to have a shorter lifespan compared to silver oxide batteries, like the SR44, which are known for providing a more stable voltage over a longer period.
If your device requires consistent performance over time (for example, in watches or cameras), opting for a silver oxide battery like the SR44 may be beneficial, even though it comes at a higher price. For low-drain devices where frequent battery changes aren’t an issue, alkaline equivalents such as the AG13 or A76 are suitable and more affordable.
3. Price Considerations
Alkaline batteries are generally cheaper than silver oxide alternatives. If you're on a budget and need batteries for low-power devices, the LR44, AG13, or A76 are perfect choices. On the other hand, if you're using the batteries in high-performance devices or need longer-lasting power, investing in a silver oxide equivalent such as the SR44 or 357 might be worth the extra cost.
4. Device Type
The device you're powering will largely determine which battery is the best option. If you're replacing a battery in a high-precision tool or a device that requires long, consistent battery life, you’ll want to go with a silver oxide battery. For more casual uses like toys or remote controls, an alkaline equivalent such as the A76 or LR1154 should suffice.
Conclusion
When choosing an LR44 equivalent, it’s important to consider your device’s requirements in terms of voltage, longevity, and price. While alkaline batteries like the LR44, AG13, and A76 are affordable and widely available, silver oxide equivalents such as the 357 and SR44 offer longer-lasting power and more stable voltage, making them ideal for high-performance devices.
The comparison table and breakdown of each option should help you make an informed choice about which LR44 equivalent is best for your needs. Whether you’re powering a simple toy or a precision instrument, there’s a suitable LR44 replacement that can keep your devices running smoothly.
