The LR44 Button Battery

Button batteries are small, cylindrical cells that can power a wide range of devices. They are also called coin cell batteries.

They are commonly used in watches, calculators, laser pointers and LED flashlights. They are made by many manufacturers and are available in several chemistries. The LR44 is one of the most common and is an alkaline battery.

LR44 Battery Size

The LR44 Button Battery is a common type of primary non-rechargeable button cell used in a variety of devices. It is a commonly used battery for watches, calculators, laser pointers, and many other small electronic devices.

The battery size is 11.6 x 5.4 mm and has a nominal voltage of 1.5V. It is also a popular replacement for AA batteries.

LR44 batteries are alkaline and have a slightly lower capacity than lithium-ion batteries. They are typically slightly cheaper than silver oxide-based 357 batteries, but they have a 30%-100% shorter lifespan and less stable voltage.

However, LR44 batteries are very useful for many devices, as they offer high storage capacity and excellent performance. They are available from a wide range of retailers, and are often considered the best value for money battery option in this category.

These batteries are commonly called ‘button/coin cells’ because they have a similar appearance to coins, and often have the polarity stamped on them (the positive side has markings that show its polarity, while the negative side is flat and protrudes). These batteries should never be swallowed as the body liquids close the circuit between the anode and cathode, which can cause serious harm or even death.

Some LR44 batteries have two-digit codes on their labels that indicate their chemistry, such as ‘L’ for alkaline and ‘SR’ for silver oxide. Sometimes they have both ‘L’ and ‘SR’ to emphasize that they are replacements for AG13/LR44/LR1154 batteries.

SR batteries are similar to LR batteries in their chemistry, but they have a slightly higher nominal voltage of 1.55 V and a slightly higher capacity. They are commonly used in watches, as their chemistry allows them to produce more power than alkaline batteries and have an extended life span.

The LR44 battery is the most common type of button cell, and can be found in many types of devices. They are commonly sold in packs of 10 or 25 and are usually priced under $4 per pack.

LR44 batteries are commonly used in watches, calculators, laser pointers, flashlights, and other small devices. They are not rechargeable, but they can be replaced when they reach the end of their life cycle.

LR44 Battery Voltage

LR44 batteries are an excellent choice for a variety of devices, including calculators, thermometers, watches, toys, remote controls, and clocks. They are also commonly used in handheld devices such as cameras and small radios.

Despite their low voltage, they can still deliver a high level of power. This makes them ideal for applications that require a compact and reliable battery, as they have the capacity to power your device for years after a single charge.

In addition to their high capacity and long life, LR44 batteries are safe to LR44 Button Battery use and can be recycled or disposed of in the same manner as regular waste. Unlike lithium batteries, they do not contain heavy metals that could poison the soil or cause a ground fill explosion.

However, they can be dangerous to children and should not be left in a children’s room or around them. Since they are a relatively small-sized battery, they can be swallowed by small children and may pose a health risk. They can also leak out and explode when short-circuited, force discharged, overcharged, overheated, or disposed of in the fire.

There are several chemistries of LR44 batteries available, with each chemistry offering different performance characteristics. They are constructed from a combination of manganese dioxide and silver oxide to produce the electrical energy they need to run your device.

A common alkaline LR44 battery has a flat side and a little round protrusion on the other end (usually with markings). The flat side is the positive side and the round protrusion is the negative side. You can easily align the positive and negative ends of your LR44 battery by following the markings on the device to which it belongs.

Silver-oxide SR44 batteries are similar in size and shape to alkaline LR44 batteries, but they have slightly higher nominal voltage (1.5V vs. 1.5V for LR44) and larger capacity (200-300 mAh vs. 110-150 mAh for alkaline). Moreover, they have a lower self-discharge rate than alkaline LR44 batteries and a longer lifespan. These batteries are more expensive than LR44 batteries, but they offer many of the same benefits and are often interchangeable.

LR44 Battery Life

The battery life of an LR44 button battery depends on the type of device and chemistry used, but generally it lasts around 135,000 to 420,000 cycles. They are commonly found in digital watches, key fobs, hearing aids, small flashlights and test instruments, and as coin cells in a wide range of electronic gadgets.

Unlike older batteries, today’s coins and button batteries are produced from non-toxic materials and do not contain mercury or other heavy metals that may be hazardous to the environment. They are also recyclable and reusable, making them a popular choice in many applications.

A common LR44 battery is flat and sometimes has markings, which can help you determine its positive and negative ends. The side with the markings is usually the positive end. A little round protrusion on the other side should indicate the negative end.

Once you’ve determined the positive and negative ends, align the battery with its corresponding markings on your device. This is especially useful for devices that have metallic tabs to hold the battery in place.

Most LR44 batteries are alkaline, which means they have no metal parts and are non-toxic. They can be disposed of in the same way as normal waste, although it’s important to follow correct disposal procedures.

The LR44 battery is available in various chemistries, each with distinct properties that are critical for their applications. When different chemistries are combined, they can react and cause overheating or explosions. It is therefore best to avoid mixing them.

Some LR44 batteries claim a higher capacity than others, but this is not always true. It’s best to read the specifications of a specific battery and compare them with other similar batteries before purchasing one.

Another advantage of LR44 batteries is that they are more durable than lithium batteries. However, they are heavier and require a higher voltage to power certain electronic devices.

Some LR44 batteries claim to have a higher capacity than silver oxide equivalents, but this is not always true. It is better to choose a battery based on the device you plan to use it with. If you’re buying a replacement battery for a device that requires a certain voltage, a silver oxide equivalent will give you the most voltage for longer periods of time.

LR44 Battery Safety

If you use LR44 button batteries with devices, be sure to store them safely. Some communities have battery drop-off bins where you can dispose of used batteries. This is a great way to prevent your kids from coming into contact with batteries and it also reduces the risk of them getting into trouble.

LR44 batteries are made of alkaline chemistry and are a popular choice for many devices. They offer a very low drain performance and are able to last for long periods of time, making them suitable for a range of applications.
