From your kids’ laser pointers to those digital thermometers you find in restaurants, the calculators and digital cameras, and wristwatches you’re still clinging to, they all rely on the LR44 for power. But what if the battery of your most important device is now making you scramble because it has just died, and you can’t immediately access an LR44 battery equivalent, replacement, or substitute?
You’re standing in the store aisle, staring at an array of similarly sized button cells that have names so confusing that they all seem to blend, like AG13, SR44, or 357. As the title suggests, this guide serves as your map through the confusion. I am going to deeply explain what the suitable LR44 battery equivalent is, explore the best options for your device, and help you gain confidence when selecting the ideal replacement.

Understanding LR44 Battery Specifications
As you seek the perfect LR44 battery equivalent, it’s a good idea to understand what this small power source actually is. The LR44 is a small and economical Alkaline battery with a nominal voltage of 1.5V.
Here are some of the core LR44 battery specifications:
- Dimensions: 11.6mm diameter × 5.4mm height
- Nominal Voltage: 1.5 volts
- Typical Capacity: 100-150 mAh
- Chemistry: Alkaline zinc manganese dioxide
- Operating Temperature: -10°C to 60°C (optimal at 20°C)
- Weight: Approximately 2 grams
- Shelf Life: 3-5 years when stored properly
Actually, the voltage of an LR44 battery doesn’t change a whole lot as it discharges, but there is some loss in voltage that goes down as it drains. This makes LR44 ideal for low-drain devices wearable devices such as watches, calculators, and small toys.
Why You Might Need an LR44 Battery Equivalent
If LR44 batteries are so common, why would you want an equivalent? There are certain scenarios in which a replacement would not just be an option, but a better decision:
- Availability: Occasionally, your neighborhood store may not have LR44 batteries in stock, but they may have an LR44 equivalent, such as the Energizer A76 or the 76A Duracell.
- Performance Requirements: For fine instruments such as high-grade digital calipers or watches, a silver oxide equivalent (such as SR44) type battery is suitable for providing a stable voltage output. This is to help ensure your device remains accurate throughout its battery lifespan.
- Durability: Silver oxide batteries have a longer life and lower self-discharge rate than alkaline batteries, so these are LR44 battery equivalents that work well for devices you use on a daily basis.
- Temperature Extremes: In cold environments, a lithium-based alternative such as the 1/3N can provide superior performance to an alkaline battery that might struggle.
Knowing what a battery equivalent to an LR44 will allow you the freedom of choosing which power supply is right for what you are using it with.

This LR44 battery equivalent chart is your starting point. Now, let’s look at these options more closely.
Silver Oxide vs. Alkaline: What’s the Right Choice?
When selecting an LR44 equivalent, the most significant decision may be between alkaline and silver-oxide chemistry.
- Alkaline (LR44, AG13, A76): These are the workhorses of button-cells. They’re inexpensive and suitable for general-purpose, low-drain devices where precise voltage stability isn’t crucial. Consider them the standard option for kids’ toys, small flashlights, and basic calculators. The downside is that their voltage slows as they drain, which can interfere with the performance of delicate electronics.
- Silver Oxide (SR44, 357, 303): These are the premium choices. A silver oxide battery holds a nearly constant voltage until the very end of its life. This makes the SR44 battery the best LR44 battery equivalent for devices that need consistent power, like a watch battery LR44 equivalent, digital thermometers, or professional instruments. They also have a longer lifespan and a lower risk of leaking, which protects your valuable electronics. Though they cost more, the reliability is often worth the investment.
Quick Decision Between LR44 Battery Equivalents
- Need a longer life for a watch or medical device? Choose a silver oxide SR44 or 357 battery.
- Powering a toy or a simple calculator? An alkaline LR44 or AG13 battery works just fine.
Top Brand-Specific LR44 Battery Equivalents
Many leading battery manufacturers produce their own LR44 equivalent, often under a different name. Here’s a handy list of some common ones:
- Duracell: Look for the 76A or 357/303. The Duracell LR44 battery equivalent is widely available.
- Energizer: The A76 is the direct LR44 battery Energizer equivalent. You may also find the Energizer 357.
- Maxell: Maxell often labels their batteries as LR44, but also offers the SR44 as a silver oxide option.
- Rayovac: The Rayovac LR44 battery equivalent is typically the 357.
- Renata: Known for premium Swiss-made watch batteries, their 357 (SR44W) is a top-tier silver oxide equivalent.
So, if you’re searching for an “LR44 battery equivalent Energizer,” you’d grab an A76. If you need the “LR44 battery equivalent Duracell,” you’re looking for a 76A.
What About Other Numbers?
You may see other numbers, such as CR2032 or 675, and ask, ‘Are they an LR44 battery equivalent?’
- CR2032: The 3V lithium coin cell (20mm diameter) is not an LR44 battery swap.
- 675: This is a zinc-air (like the A10 above) cell generally used in hearing aids. Its size would be a good replacement for the popular LR44 chemistry battery.
Always adhere to the direct equivalents as specified in the MAHLE part number for fit, form, and function.
A Note on Handling and Safety
All button cell batteries, including every LR44 battery equivalent, require careful handling.
- Storage: Keep them in their original packaging in a cool, dry place.
- Leakage: Although this is rare, it can occur if the battery leaks. Silver oxide batteries are generally less prone to leaking than alkaline batteries.
- Disposal: Never put batteries in household trash. Nearly all electronics and local recycling centers house designated bins for battery disposal.
- Child Safety: These small batteries are a serious swallowing hazard. Keep them out of reach of children at all times.
How to Choose the Right Equivalent
Still feeling overwhelmed? You’ll find the correct LR44 battery equivalent for your requirements quickly and easily with this guide.
- Examine Your Device’s Manual: This is where you should always start. Many Battery types are compatible with multiple battery types.
- Consider the Device Type:
- For toys, laser pointers, or basic calculators: An alkaline LR44 or AG13 is just about perfect and cheap.
- For watches, digital calipers, or for medical devices: These SR44, 357/303, and L1154 are 1.55V and ideal for applications with a continuous, low power consumption, such as watches or medical devices.
- For a device using two LR44s in cold weather: try a 1/3N lithium.
- Check Voltage and Dimension: Make sure the replacement is 1.5V (or 1.55V for silver oxide) with a dimension of 11.6mm x 5.4mm. If you measure it, make out these two figures -Se game on! There are alternatives, such as the LR41 or LR43, but their size is not right and they won’t fit.
So next time your device goes off, you’ll know exactly which LR44 battery equivalent to reach for.
FAQs
The most popular equivalents for the LR44 battery are AG13, A76, L1154, SR44, 303, and 357 models. AG13 and A76 are a straight alkaline battery replacement; however, SR44, 303, and 357 are silver oxide improvements to the alkaline in performance and lifespan.
Yes, the AG13 is essentially a direct equivalent of the LR44 in most aspects. They are the same size as other alkaline batteries, and can be used to replace those in most devices.
Absolutely. A 357 battery, on the other hand, is a silver oxide LR44 equivalent. It provides a more reliable voltage and a longer lasting time of use, which is great for your tool and even higher for usage in flashlights, cameras, watches, toys, and other electrical devices etc.
The most popular equivalent of the LR44 Energizer battery is the A76. You might also find the Energizer 357, which is the silver oxide variation.
Not typically, but they can perform differently. Unbranded batteries tend to have a shorter lifespan and are more prone to leaking, which can ruin electronics. Going with reliable brands like Duracell, Energizer, or Maxell should give you peace of mind.
Buy only from trusted retailers to avoid counterfeits. Look for professional packaging with easy-to-find branding and production information. Really cheap prices or flimsy packaging can also be an indicator.
