What are LR44 Batteries? Usage, structure, Equivalence and Differences with other batteries
The LR44 battery is in everything from medical devices to children’s toys. Batteries are what makes our lives possible every day. They are in everything from electronic devices to vehicles. They power everything, which makes them indispensable for all uses. For instance, if one had to use their cellphone during an emergency or accident, they want to be sure that their phone will power on and let them call someone for help. It is just one example of how indispensable and vital batteries are in our everyday lives.
What are LR44 Batteries?
The LR44 battery is a 1.5V non-rechargeable alkaline button battery. Powerful, and long-lasting because of the frequency in which they are used. These batteries frequently discharge. Approximately 1.5 volts is the nominal voltage of this alkaline single-cell battery. It has a shelf life of between 2-5 years, a average capacity of 110mAh, and a shelf life of 2-5 years. The batteries are still reliable even though they have a short lifespan or deteriorate with frequent use. This battery’s advantages are that it is more affordable, highly compatible with most devices, functions efficiently in varying weather conditions, and is readily available in most places.
Why do we use LR44 batteries?
A long-lasting alkaline button cell battery, the LR44 battery is used primarily in portable devices. Due to its compact design and reasonable price, it is a popular choice. It is easily accessible in stores due to its popularity for personal use. High-end premium batteries and standard batteries are grouped. Battery manufacturers are known for their durability, high capacity, high energy density, and reliability due to their desirable features, including their price.
Devices that use an LR44 battery, include:
- electronic keys
- computer motherboards
- gun sights
- medical equipment
- electronic toys
- laser pointers
- dog collars
- small radios
- hand watches
- and a lot of other portable electronics.
The structure of LR44 batteries:
Battery dimensions are 11.6mm diameter, 2.5 grams weight, and 5.4mm height. Be sure to compare details such as the battery type, dimension, capacity, maximum voltage or current, and its chemistry when you need to replace your portable device’s battery. Some devices cannot be operated correctly if powered with a voltage less than the threshold voltage; Silver Oxide batteries can replace LR44 batteries. The alkaline label LR or AG on the package list signifies alkaline batteries. A designation of SR indicates silver oxide.
- Chemistry: Alkaline
- Diameter: 11.6mm
- Height: 5.4mm
- Voltage: 1.5V
- Capacity: 120mAh
- Weight: 1.75g
- Operating Temperature: -18℃ to 55 ℃
What is an LR44 battery equivalent to?
First lets start with alkaline equivalents and then other chemical compositions. Technically all batteries below will replace the LR44 but depending on your intended application, some may not be suitable or economical.
LR44 Alkaline Battery Equivalents
Silver Oxide Equivalents
- CR44, CA18, CA19
- 1131SO, 1131SOP, 1107SO,1166A,
- 280-62, 280-08, 154E
- 303, GP303, 303X, 303A, E303, D303, P303, D357, D357H
Silver oxide battery voltage is slightly higher (approximately 1.55 volts) than standard alkaline batteries, while capacity ranges from 160 to 200 mAh, and shelf life is about 5 years and longer. This battery has the advantage of providing a more stable voltage output, meaning that despite frequent usage, it will not drain as fast as an alkaline battery. Watches and calculators are among the main electronic devices that they are used in. Silver oxide batteries’ downside is their high cost in comparison to alkaline batteries.
Mercury oxide batteries:
It is not safe to use MR44 or MR1154 batteries (magnesium in these batteries is hazardous). These batteries are no longer sold to consumers and must be disposed of properly. DO NOT USE MERCURY OXIDE BATTERIES. We are just including this here as a reference as technically they are compatible with LR44 batteries.
There are three blue tabs: PR44, 675, ZA675. Batteries with this voltage have a higher capacity range of 600-700mAh in comparison to alkaline batteries. When the electrolyte dries up without being depleted, they become dead because they use oxygen. Because of this feature, they are mainly used in hearing aids and not in highly reliable devices.
How are lithium batteries and LR44 batteries different?
Most power sources use lithium or LR44 batteries. However, even though these batteries are typically used in small portable devices, the chemical composition and voltage ranges vary widely. One major difference between the two types of batteries is that the LR44 battery has a shorter lifespan than the lithium battery. Here are the differences between the two types of batteries;
In contrast, lithium batteries use lithium metal as their anode, while LR44 batteries use zinc and manganese oxide to generate power.
The charge level of lithium batteries is higher than the charge level of alkaline batteries (voltage of 1.75 or more than 1.5V in LR44). They have a longer shelf life than LR44 batteries, giving them a competitive edge.
Lithium batteries are more expensive than LR44 batteries, so they are not very cost-effective.
Batteries made from lithium are extremely powerful. Therefore they are more toxic to the environment and human health, making them more hazardous to dispose of. By contrast, the LR44 battery does not contain heavy metals, which could cause soil pollution or ground fill explosions. Due to their non-toxic nature, they can be disposed of with other household waste. Despite this, batteries of whatever type are still best disposed of according to the proper guidelines.
The LR44 battery has higher weight or more weight than lithium batteries.
Despite their lower voltage, LR44 batteries can hold their charge very well when in use. While lithium batteries provide more power, their self-discharge is high.
The information about LR44 batteries, their uses, their equivalents, and their differences with lithium batteries should now be clear to you. After reading the above article, I believe you will never have any trouble distinguishing LR44 batteries from other types. To determine whether a different battery can replace the LR44 battery, check and compare details on a battery or battery pack.
