LR44 Battery Equivalents, Specifications, and Sourcing Guide

The LR44 is one of the most widely used 1.5V button-cell batteries. This guide explains what an LR44 battery is, its equivalent model codes, the difference between alkaline and silver-oxide versions, and how distributors and manufacturers can choose the right model.

1. What Is an LR44 Battery?

The LR44 is a 1.5V alkaline button-cell battery measuring approximately 11.6mm in diameter and 5.4mm in height. Thanks to its compact size and stable output, it is used in many consumer and industrial devices, including:

Toys

Calculators

Laser pointers

Medical devices

Digital thermometers

Small LED lights

Because of its popularity and standardized dimensions, the LR44 remains a preferred choice for product designers and manufacturers worldwide.

2. Common LR44 Equivalent Model Codes

Manufacturers across different regions label LR44 batteries under various codes. These model names refer to the same size and voltage:

AG13

A76

L1154

PX76A

V13GA

Understanding these equivalent codes is essential for global sourcing and cross-brand compatibility.

3. Alkaline vs. Silver-Oxide Versions (LR44 vs. SR44/357)

LR44 refers specifically to the alkaline version. The silver-oxide alternative is labeled SR44 or 357. Key differences include:

Type	Details
Alkaline (LR44 / AG13 / A76)	- Lower cost - Suitable for low-drain devices - Widely used in daily consumer electronics
Silver-Oxide (SR44 / 357)	- More stable 1.55V output - Longer lifespan - Preferred for watches, instruments, and precision devices

Choosing the correct chemistry ensures optimal performance and stability.

4. Choosing the Right Equivalent for Your Application

Low-drain or cost-sensitive devices

Use alkaline LR44/AG13/A76. They offer good performance at a lower price.

High-drain or precision devices

Use SR44/357 silver-oxide cells for stable voltage and longer runtime.

For manufacturing and bulk sourcing

Always verify product authenticity, packaging, and batch numbers. At VIGOR Components, our team helps ensure safe, reliable, and counterfeit-free sourcing.

5. Sourcing Considerations for Distributors and Manufacturers

When sourcing LR44 batteries or equivalents, keep the following in mind:

Verify exact model codes (AG13, A76, L1154, etc.)

Check authenticity: labels, date codes, and batch numbers

Match the chemistry type to the device's power profile

Offer both alkaline and silver-oxide variants to customers

Follow proper disposal and recycling guidelines

These steps help maintain product reliability, reduce returns, and ensure compliance with safety standards.

6. Frequently Asked Questions

Q: Are LR44 and AG13 the same?
A: Yes. Both refer to the same 1.5V alkaline button cell.

Q: Can SR44 (357) replace LR44?
A: Yes, but SR44 has a more stable voltage and longer life.

Q: Can LR41 or LR43 be used instead?
A: No. They are different sizes and are not compatible.

Q: How long does an LR44 battery last?
A: Typically 6–12 months in low-drain devices. Precision devices usually benefit from SR44.
