Are you considering investing in a button cell battery but have no clue which one to buy? Since these batteries come in different sizes and voltages, there are too many choices, and it can get hard to determine which may suit your needs. From the LR44 to LR1154 battery, each battery has certain unique properties and are used in varying products.
In this guide, we will look at each button cell battery in detail to know which one deserves your money.
What Is a Button Cell Battery?
Also known as a coin cell or watch battery, a button cell battery looks like a circular and stainless steel disc that generates power for portable devices such as computers and watches. These batteries are pretty small and are often crucial for computers as they help these machines retain their system setting even if they are off. Besides, they are also found in many toys, watches, and toys that you use on a daily basis.
Most button cell batteries consist of lithium, alkaline, or silver oxide. Moreover, they can last for many years, provided you use them with care.
A button cell battery often has a diameter between five and 25mm. Further, its height varies between one and six mm.
What’s more, a coin cell battery comes with two terminals. There is a positive terminal made of stainless steel and is adjusted at the battery’s bottom. On the other hand, a negative terminal forms the battery’s top cap and is entirely insulated.
One of the most appreciated characteristics of button cell batteries is their longevity. These batteries have a low self-charge feature, meaning they can stay charged for an extended duration. This is why they are pretty popular.
Four Categories of Button Cell Batteries
Interestingly, there are four primary categories of button cell batteries. Below we have explained each type in detail.
These batteries are the same size as other options, but these batteries offer less silver oxide and lithium batteries when it comes to voltage and capacity. Both LR44 and LR1154 are alkaline batteries.
This category of button cell batteries has a stable discharge. You may find them in most precision devices and medical instruments. For instance, SR44 is a silver-oxide button cell battery.
Although it has a stable discharge, this battery isn’t used anymore because of its lethal and toxic nature. Unfortunately, this battery can be a massive reason behind air pollution when disposed of correctly.
Labeled as the “next-generation batteries,” a zinc-air battery has a much higher capacity than other options. Also, it comes with safety mechanisms and a high potential to hold more energy. Moreover, the cost per unit of this battery is pretty low.
What Is the Electrochemical System?
This term defines a cell that uses more than one electrode. It features an IEC 60086-3 standard that helps define these cells through unique alphanumeric codes.
For instance, alphabets C, S, and L are alphabets used for lithium, silver, and alkaline batteries, respectively. These batteries are primarily used in watches and small devices. Alternatively, the alphabet P represents zinc-air batteries used in hearing aids and medical instruments.
Benefits of an Excellent Button Cell Battery
Here are some ways in which a button cell battery is relatively useful.
Most button cell batteries are made of chemically stable materials. This means the chances of leakages and short circuits reduce manifold.
Button cell batteries are pretty durable and therefore don’t require frequent replacement. Besides, they ensure that all the appliances run smoothly, increasing personal safety and reducing the chances of any potential disasters.
Most high-quality button cell batteries have excellent conductivity. Otherwise, they fail to perform well.
Most rechargeable button cell batteries have a long life. Most units have a capacity of more than 80%, and the discharge and charge cycle can be recycled after almost 400 weeks, which is a significantly long time.
Finally, button cell batteries are far more cost-effective and affordable than other batteries. They have a praise-worthy power performance and are usually inexpensive.
Exploring and Comparing the Different Types of Button Cell Batteries
Now that we know the basics let’s explore and compare different types of button cell batteries. Both alkaline and silver-oxide batteries have equivalent batteries. For instance, LR44 is an alkaline battery and has comparable batteries such as A76, AG13, G13, LR1154, L1154, 154, and many more.
Similarly, many silver-oxide batteries have equivalent batteries like SR44, SR44SW, SR44W, SB-B9, 303, and 357. All silver-oxide batteries can easily replace alkaline button cell batteries and are often found in watches.
In this guide, let’s find out how most common button cell batteries are different from each other.
Our first battery is LR44, and it falls under the alkaline category. This means that it is the same size as other alkaline batteries and can be used interchangeably. Moreover, this battery is compatible with most silver-oxide counterparts.
The silver-oxide battery version that you can use to replace an LR44 battery is labeled with a name that starts with the alphabets SR.
This battery is often designed for general use and has a nominal voltage of 1.5V. Further, it has a diameter of 11.6mm and a height of 5.4 mm.
There are many batteries that are equivalent to an LR44. If you want to replace an LR44 directly, you can do so with a Duracell 76A, Energizer A76, and AG13 batteries. All these batteries are precisely similar to an LR44 battery; the only difference is their names.
Fortunately, you can use an LR44 for many devices. For instance, it can be found in calculators, digital thermometers, wristwatches, flashlights, and even laser pens.
AG13 and LR44 are precisely the same alkaline button cell batteries. Therefore, they are entirely interchangeable with the exact dimensions. What’s more, like an LR44 battery, AG13 also has many names and can be replaced by many silver-oxide and alkaline batteries.
For instance, Energizer 303 or 357 is a direct replacement for an AG13 battery. Moreover, it also has other names such as A76 and 157. This battery features 1.5 Volts power and is often used in watches, toys, and clocks.
Another alkaline battery on the list, LR1154, is a compact and long-lasting unit. It has a nominal voltage of 1.5V and is commonly found in watches. With a height of 5.4mm and a diameter of 11.6mm, this battery provides incredible continuous power and has an extended life.
In addition to this, it works effectively under both high and low temperatures. There are many other batteries that are compatible with an LR1154 battery. They include LR44 and AG13, to count a few.
While SG13 is the same size as an LR44 battery, it performs better and has a long life. An SG13 is a silver-oxide button cell battery and features 1.55V.
There are many excellent benefits of using this battery. It generates a steady output for starters, making it compatible with most devices. Besides, you don’t need to charge this battery often, saving you lots of hassle and time.
The dimensions of this battery are 11.6 mm x 5.4 mm or 0.457 x 0.213 inches, and it weighs around 2.3 grams. Furthermore, it has a capacity of 165mAh.
An SG13 battery is often used in popular devices such as calculators, insulin pumps, digital voltmeters, swatch watches, and most children’s talking books.
