LR44 Battery Equivalent The LR44 battery is a common button cell used in devices like calculators, watches, and toys. Here are some compatible equivalents and their characteristics:

SR44 (Silver Oxide Battery): Provides 1.55V with a capacity of about 150mAh. It offers longer life and is suitable for high-drain devices. Common equivalents include 303, 357, AG13, and G13-S. AG13 (Alkaline Battery): Delivers 1.5V with a capacity of approximately 110mAh. It is more affordable but has a shorter lifespan, ideal for low-drain devices. Also known as LR44 or A76. LR1154 (Alkaline Battery): Similar to AG13 with 1.5V and 110mAh capacity. Often labeled as LR44 or AG13. 357/303 (Silver Oxide Battery): These are alternate names for SR44, providing 1.55V and 150mAh with excellent performance. CR44 (Lithium Battery): Produces 3.0V, making it unsuitable for direct replacement due to higher voltage.

Summary For cost-effectiveness, choose alkaline batteries like AG13 or LR1154. For better performance and longer life, opt for silver oxide batteries like SR44 or 357. Always check compatibility with your device, especially the voltage and chemical composition. ​

​ LR44 vs 357: Which One is better? When comparing the LR44 and 357 batteries, the primary differences lie in their chemistry, performance, and typical usage. Here’s a breakdown to help you decide which one is better for your needs:

Chemistry: LR44 is an alkaline battery, while 357 is a silver oxide battery. Silver oxide chemistry is generally more stable and provides consistent voltage output over its lifespan, whereas alkaline batteries experience a gradual voltage drop as they deplete.

Voltage: Both batteries provide similar nominal voltages: 1.5V for LR44 and 1.55V for 357. While the difference is small, the 357’s consistent output makes it preferable for precision devices like watches or medical instruments.

Capacity and Lifespan: The 357 battery has a higher capacity (around 150mAh) compared to the LR44 (typically 110mAh), giving it a longer runtime. Silver oxide batteries like the 357 also retain their charge longer when stored, making them better for long-term use.

Cost: LR44 batteries are usually cheaper due to their alkaline chemistry. 357 batteries are more expensive but deliver better performance and reliability.

Usage: LR44 is sufficient for low-drain devices like toys, basic calculators, and remote controls. 357 is better suited for high-drain or precision devices, including watches, cameras, and hearing aids.

Conclusion If cost is your primary concern or your device doesn’t require consistent voltage, the LR44 is a good choice. However, for devices that demand precision or long-lasting performance, the 357 is the better option due to its superior stability and higher capacity.

LR44 vs LR41: Which One is better? When comparing the LR44 and LR41 batteries, it's essential to consider their specifications, applications, and overall performance to determine which one may be better suited for your needs:

Size and Capacity The LR44 battery is larger than the LR41, with a diameter of 11.6 mm and a height of 5.4 mm, compared to the LR41's dimensions of 7.9 mm in diameter and 3.6 mm in height. This size difference also translates into a significant difference in capacity; the LR44 typically has a capacity ranging from 110 to 160 mAh, while the LR41 has a much lower capacity of about 25 to 32 mAh. This means that the LR44 can provide power for a longer duration, making it more suitable for high-drain devices.

Applications The LR44 is commonly used in various applications that require reliable and sustained power, such as medical devices (like glucose meters and hearing aids), remote controls, toys, LED lights, and digital thermometers. Its higher capacity makes it ideal for devices that demand more energy. In contrast, the LR41 is often found in smaller electronic devices where space is limited, such as wristwatches, small calculators, laser pointers, and certain medical instruments. While it is dependable for low-drain applications, it may not be suitable for devices that require more power.

Performance In terms of performance, the LR44 generally outperforms the LR41 due to its larger size and capacity. For devices that can accommodate both batteries, using an LR44 instead of an LR41 may result in longer usage times because of the former’s superior energy output. However, it is crucial to ensure that the device can physically accommodate the larger size of the LR44.

Conclusion Ultimately, whether the LR44 or LR41 is "better" depends on your specific needs: Choose the LR44 if you need a battery for high-drain devices or applications requiring longer battery life. Opt for the LR41 if you are working with compact devices that require less power and have limited space. Using the correct battery type as specified by the manufacturer is always recommended to ensure optimal performance and safety.

357 Battery Equivalent The 357 battery is a silver oxide button cell commonly used in watches, cameras, and other precision devices. If you’re looking for equivalents, here are some options:

SR44: This is the direct equivalent of the 357 battery, also using silver oxide chemistry with the same 1.55V output and high capacity. It is reliable for devices requiring stable voltage.

AG13 (Alkaline): While not a perfect substitute, AG13 can replace the 357 in many cases. However, it uses alkaline chemistry, provides a slightly lower capacity, and experiences a quicker voltage drop.

LR44 (Alkaline): Similar to the AG13, this is a common replacement for the 357 but with shorter lifespan and less consistent performance due to its alkaline chemistry.

303: Another silver oxide battery, often marketed interchangeably with the 357. It shares the same voltage and chemistry.

A76: This alkaline battery is compatible with the 357 in terms of size and voltage but performs better in low-drain devices.

Summary For the best performance, use silver oxide options like SR44 or 303 as direct equivalents to the 357. Alkaline options like AG13 or LR44 are more affordable but less durable, making them suitable for low-drain devices or temporary replacements. Always check device requirements before substituting.

Are LR44 and L1154 Battery Equivalent? LR44 and L1154 batteries are indeed equivalent. Both types are alkaline button cell batteries with identical specifications, including: Nominal Voltage: 1.5 volts Dimensions: 11.6 mm in diameter and 5.4 mm in height Chemistry: Alkaline

These batteries can be used interchangeably in most applications due to their similar physical dimensions and electrical characteristics. The L1154 designation is often used as an alternative name for the LR44, along with other equivalents like AG13 and A76. While both battery types perform similarly, it's important to note that slight variations in thickness or manufacturing quality may exist, which could affect compatibility in certain devices. However, for general use, they can be considered interchangeable.
