LR44 Battery (A76 Battery)

The LR44 battery is an Alkaline Zinc Manganese button cell battery. The LR44 battery is typically a 1.5 Volt with an operating temperature ranging from 0°C- 60°C, while optimal temperature is 20°C

Here at microbattery.com, we carry a wide variety of different LR44 batteries from many of the top brands in the industry. We carry high end premium batteries as well as more standard batteries at affordable prices. These batteries stand for durability, high capacity, high energy density and reliability. They help to provide reliable performance, high efficiency, and a long service life.

The LR44 battery can be utilized in many devices such as watches, motherboards, and a variety of medical devices like thermometers. LR44 battery equivalents are also referred to as A76, AG13, L1154, LR1154, 157. These sizes are possible LR44 battery replacements. There are other batteries that are similar to the LR44 battery but are different in composition chemistry. The LR44 battery is identical in size, but different in chemistry to silver oxide button cells such as SR44, SR44SW, 303, 357. Although batteries can fit into each other's devices fairly easily, it is important to choose the recommended battery type for your device to avoid over/under discharge.Please be sure to double check the size and voltage of the battery you need, to avoid any issues that can damage your device.

What Are LR44 Batteries? 

 

The LR44 Battery is a small button cell battery of alkaline-manganese composition. The LR44 is a very common battery and is produced by many large brands such as Toshiba, Maxell, Energizer, and more. The LR44 battery is also widely produced by smaller companies and private label battery manufacturers, for example Tianqiu produces the LR44.

Depending on the manufacturer, batteries of the same size and capability of LR44, are referred to in a few different variations. Direct replacements for LR44 would be Duracell 76AEnergizer A76, and AG13 batteries. These batteries are exact equivalents for the LR44 battery, the only difference being the name. These batteries can all be interchanged.

There are also some batteries that are the same size and dimensions as the LR44 battery, but are not exact equivalents or direct replacements as they are constructed of different chemistries offering different performances for varying applications. Examples of these could be the 303, SR44, SR44SW, and 357 silver oxide batteries. Although these batteries are of the exact same dimensions as an LR44 battery, the silver oxide chemistry offers a very low drain performance allowing the battery to work over extended periods of time in low use applications such as in a watch. One of the most common questions about LR44's is "are lr44 batteries the same as 357?". Long story short, the 357 battery is simaler to the LR44 but not exactly the same when it comes to cost or performance.These batteries may not work in all applications that require a LR44 battery. 

 

How To Put LR44 Batteries In Your Device


First identify the positive and negative ends of the battery. On a typical Alkaline LR44 battery, the flat side (possibly with markings) will usually be the positive side. On the opposite side, a small circular protrusion should be visible. The side is typically the negative end. Now that you have determined the positive and negative ends of the battery, you can easily align it with corresponding markings on your device. Please note that some devices have small metallic tabs for battery retention and function. It is very important to leave these tabs unharassed and undamaged as doing so may compromise the performance of your device. If you do slightly move this tab out of place, they can usually be fixed by carefully readjusting them back into the proper orientation.

For the best results, always consult the owner’s manual of your device to determine the exact battery that is required.

Are LR44 batteries the same as 357?

There are also some batteries that are the same size and dimensions as the LR44 battery, but are not exact equivalents or direct replacements as they are constructed of different chemistries offering different performances for varying applications. Examples of these could be the 303, SR44, SR44SW, and 357 silver oxide batteries. Although these batteries are of the exact same dimensions as an LR44 battery, the silver oxide chemistry offers a very low drain performance allowing the battery to work over extended periods of time in low use applications such as in a watch. One of the most common questions about LR44's is "are lr44 batteries the same as 357?". Long story short, the 357 battery is simaler to the LR44 but not exactly the same when it comes to cost or performance. These batteries may not work in all applications that require a LR44 battery.
