LR44 VS 357 battery:How to Choose

Batteries are essential for powering all kinds of electronic devices, from watches to calculators. When it comes to coin-cell batteries, LR44 and 357 are two of the most popular options. This article takes a close look at the differences between LR44 and 357 batteries, focusing on their features, uses, lifespan, and chemical reactions.

 

The R44 battery is great for all sorts of things, like Christmas decorations, small flashlights, night lights, mini LED lights, laser pointers, fingerling toys, children's electric toys, and even infants' books.

 

LR44 VS 357 battery: Overview

 

 I'm looking for advice on the best battery to use with my LR44 vs. 357. LR44 and 357 batteries are both small button-cell batteries that you'll find in lots of different electronic devices. They're pretty similar in terms of size, voltage, and what they're used for. They're often interchangeable in many devices, but it's always a good idea to check the specific requirements of your device to make sure you're using the right battery.

 

The Energizer 357 battery is a small, round, button-cell battery that falls into the category of alkaline batteries. It's 11.6 mm in diameter and 5.4 mm thick. You might also see this battery referred to as an SR44, AG13, or LR44, which are the equivalent model numbers for the same type of battery from other manufacturers.

 

The Energizer 357 battery is a popular choice for powering small electronic devices like calculators, watches, digital cameras, and some medical equipment. It has a voltage of 1.5 volts and a capacity of about 150 mAh. You can also find the battery in most stores that sell batteries. You can buy it in individual packages or in larger multi-packs.

LR44 is a type of alkaline button cell battery that goes by a few different names, including AG13, A76, and 357. It's a small, round, flat battery that's commonly used in small electronic devices like calculators, watches, digital thermometers, remote controls, and toys. While you can't recharge LR44 batteries, you can replace them when they die. In most cases, you can expect an LR44 battery to last between 50 and 200 hours.

 

LR44 batteries are about 11.6 mm in diameter and 5.4 mm thick, and they usually have a voltage of around 1.5 volts. They're often sold in multi-packs and are pretty affordable. LR44 batteries have a long shelf life and are designed to provide a stable voltage output over a long period of use.

 

Just a heads-up: LR44 batteries aren't rechargeable, so they shouldn't go in the regular trash. They contain harmful chemicals. Instead, they should be recycled properly, in line with local regulations.

LR44 vs. 357 battery:  The 357 battery has a lot going for it, which is why it's a popular choice for so many small electronic devices. Some of the benefits of the Energizer 357 battery include:

 

It lasts a long time. The Energizer 357 battery has a high energy density, which means it can deliver more power for a longer time. It has a capacity of about 150 mAh, which means it can power devices for a long time before needing to be replaced.

 

You can count on it to be reliable. The Energizer 357 battery is made to high standards and is designed to be reliable and dependable. It has a stable output voltage, which means the devices it powers work consistently.

 

It works with a lot of different devices. The Energizer 357 battery is a standard size used in many small electronic devices, and it comes in different model numbers, so it's compatible with a wide range of devices.

 

It's a convenient size. The Energizer 357 battery is small and compact, which makes it easy to carry and store. It's also lightweight, which makes it a great choice for portable devices.

 

Alkaline chemistry: The Energizer 357 battery uses alkaline chemistry, which gives it a longer shelf life and better performance in high-drain devices than other types of batteries.

 

Just to give you a heads-up, the LR44 battery is:

 

As a general rule of thumb, you can expect an LR44 battery to last between 50 and 200 hours.

 

Since the LR44 is a flat battery, it can be tricky to find the positive and negative terminals. The side with markings is the positive terminal, and the other side has a small circular protrusion that is the negative terminal.

 

You can also get button batteries in silver oxide chemistry. However, the most popular option is the alkaline variant. This battery is very reasonably priced and offers great value for money.

 

Another plus is that LR44 is free of toxic materials like mercury or cadmium. So they're eco-friendly and can be thrown away easily. They're lightweight, so they're often the go-to for projects where weight is a big issue.

LR44 vs. 357 battery: lifespan

Both the LR44 and 357 batteries have a pretty long shelf life, making them great for storage. As a rule of thumb, they can keep their charge for up to five years if you store them properly in a cool, dry place. However, how long they last in a device depends on things like how it's used and what it needs in terms of power.

 

Let's compare the LR44 and 357 batteries. Chemical Reaction

 

Here's the chemical reaction formula for a 357 battery:

 

Silver oxide (Ag2O) + zinc (Zn) = silver (Ag) + zinc oxide (ZnO)

 

In the battery, the silver oxide acts as the positive electrode (cathode) and the zinc as the negative electrode (anode). As the battery operates, the silver oxide reacts with the zinc, creating silver and zinc oxide and generating an electric current.

Here's the chemical reaction formula for an LR44 battery:

 

Manganese dioxide (MnO₂) + zinc (Zn) = manganese (Mn) + zinc oxide (ZnO)

In the battery, the manganese dioxide acts as the positive electrode (cathode) and the zinc as the negative electrode (anode). As it operates, the manganese dioxide reacts with the zinc to create manganese and zinc oxide, which generates an electric current.

 

Here's a quick comparison of the IR44 vs. 357 dimensions.

Is 357 the equivalent of an LR44 battery?

 

The 357 and LR44 batteries use different materials and chemical processes to produce power. The silver oxide 357 battery works better than the alkaline LR44 battery. The 357 battery keeps a steady voltage of about 1.55 volts until it's almost out of chemical energy, at which point the voltage drops quickly. The voltage of the LR44 alkaline battery drops gradually as it discharges.

 

While devices need a constant voltage, you can use the 357 and LR44 batteries interchangeably for most applications. The 357 is great for devices that need a constant voltage, like precision calipers and some timepieces. If you're working with devices that need more energy, the 357 is a great choice because it has a higher usable capacity.

 

What are the equivalents of an LR44 battery?

 

 

The LR44 battery, also known as AG13, A76, or 76A, has a few different equivalent battery types because different standards organizations use different naming conventions. Here are some of the most common equivalents:

 

AG13: You'll often see AG13 used in the United States. It's another alkaline option that's similar in size and voltage to the LR44. It has a slightly lower capacity than the LR44, but it can still be used in some devices that require LR44 batteries.

 

A76 is another common name in the United States. You'll also see the A76 name a lot in the United States.  The A76 is also an alkaline battery, just a little bit larger than the LR44. It's got the same capacity and voltage as the LR44. On the other hand, the A76 can last longer in certain devices than the LR44.

 

The LR1154 is commonly used in Europe. It's the same size as the LR44. The only real difference between them is who makes them and the specific chemistry used.

 

SR44: You'll often find SR44 batteries in photography equipment.  It's the same size and shape as the LR44, but it has a slightly higher voltage (1.55 vs. 1.5 volts) and a longer lifespan.

 

The 303 (which is commonly used in Canada) is another silver oxide battery. It has the same voltage as the LR44 (1.5 volts), but it can hold more charge, so it lasts longer.

 

These batteries are all pretty much the same in terms of size, voltage (1.5 volts), and capacity. They're often interchangeable in devices that require an LR44 battery. That said, it's always a good idea to check the specific requirements of your device to ensure compatibility.
