You’ve been there: a favorite calculator, laser pointer, or digital thermometer suddenly dies. You open the battery compartment and find a small button cell with a confusing code: A76. You go to the store, but all you can find are batteries labeled LR44, 357, or SR44. Are they the same? Will they work? This frustration is common, but it doesn’t have to be. The world of button cell batteries, with its overlapping naming conventions from different manufacturers and standards, is needlessly complex. This guide will eliminate the confusion. We will provide a definitive A76 battery equivalent chart, explain the crucial differences between the types, and help you confidently choose the exact battery you need.
1.0 The Ultimate A76 Battery Equivalent & Cross-Reference Chart
Let's get straight to the point. If you need a replacement for an A76 battery, you have several options.
1.1 Direct Equivalents (The Quick Answer)
The short answer is: the most common, direct equivalent for an A76 is an LR44. They are both 1.5V alkaline button cells of the exact same size.
- Direct Alkaline Equivalent: LR44 (this is the IEC standard name), AG13, G13, L1154.
- Superior Silver-Oxide Replacement: 357 or SR44. These are the same size and will work perfectly, offering better performance (more on that below).
1.2 A76 Cross-Reference Chart by Manufacturer
Different brands use different model numbers, but they all refer to one of two chemistries: Alkaline or Silver-Oxide. All batteries in this chart are the same physical size.
| Chemistry | Common Name | IEC Name | Energizer | Duracell | Varta |
|---|---|---|---|---|---|
| Alkaline | A76, AG13 | LR44 | A76 | PX76A | V13GA |
| Silver-Oxide | 357, 303 | SR44 | 357 | D357/D303 | V357 |
Essentially, if you need an A76, you can confidently buy any battery in this chart. For a list of available options, check out our LR44 / A76 batteries at aichiplink.com.
2.0 What is an A76 Battery? Core Specifications
The A76 is a popular button cell battery defined by its chemistry, voltage, and physical size.
2.1 A76 Battery Voltage and Chemistry
| Specification | Value |
|---|---|
| Chemistry | Alkaline (Manganese Dioxide) |
| Nominal Voltage | 1.5 Volts |
| Typical Capacity | ~110-130 mAh |
| Shelf Life | ~3 years |
2.2 A76 Battery Dimensions and Weight
All the batteries in the cross-reference chart share the same physical dimensions, as defined by the IEC standard.
- Diameter: 11.6 mm
- Height: 5.4 mm
- Weight: ~2 grams
3.0 A76 vs. LR44 vs. 357 vs. SR44: A Detailed Comparison
While all these batteries are physically interchangeable, the most important difference is Alkaline (A76/LR44) vs. Silver-Oxide (357/SR44).
3.1 Alkaline vs. Silver-Oxide: The Key Difference
The primary difference is how they discharge. An alkaline battery's voltage gradually drops throughout its life. A silver-oxide battery maintains a very stable, flat voltage until the very end of its life, at which point it drops off suddenly.
This stable voltage is critical for certain electronics. As an Energizer technical document would show, the flat discharge curve of silver-oxide is a premium feature.
"Think of it like this: Alkaline is a flashlight that slowly gets dimmer over weeks. Silver-Oxide is a flashlight that stays perfectly bright for its entire life and then suddenly goes out."
3.2 When to Use Silver-Oxide (357/SR44) as a Superior Replacement
While an A76/LR44 will work in most devices, you should choose the silver-oxide (357/SR44) version when:
- The device is a precision instrument: Calculators, digital calipers, and some medical devices (like glucose meters) require a stable voltage for accurate readings.
- The device is a watch: The stable voltage is essential for accurate timekeeping in analog quartz movements.
- You want longer life: Silver-oxide batteries typically have a slightly higher capacity and a much longer shelf life (5-10 years) than their alkaline counterparts.
4.0 Common A76 Battery Applications & FAQ
Thanks to their small size and decent capacity, the A76 and its equivalents are found in countless small electronic devices.
4.1 What Uses the A76 Battery?
- Calculators
- Watches
- Laser Pointers
- Digital Thermometers
- Small Toys
- Flashing Novelty Items
- Some Medical Devices (e.g., glucose meters)
Navigating the world of button cell batteries doesn't have to be a headache. The key takeaway is simple: the A76 battery is a 1.5V alkaline cell, and its most common twin is the LR44. For better performance and a longer life, especially in precision electronics, the silver-oxide 357 or SR44 is an excellent and highly recommended upgrade. Armed with this knowledge, you can replace your batteries with confidence and keep your small devices running perfectly.
