The LR44 alkaline battery is a powerful, long-lasting button cell. Apart from its compact shape, this alkaline battery has economic value and a nominal voltage of 1.5V. It works efficiently in both high and cold temperatures and is powered by the reaction between manganese dioxide and zinc, which in turn powers your devices. LR44 batteries are more affordable than silver oxide batteries, while still providing high capacity and long service life. Such cells are used in products like calculators, electronics toys, small radios, cameras and portable electronics. The following are some of the most suitable equivalents of LR44 batteries.
Ever wondered which type of battery powers your hand watches? The AG13 is an alkaline zinc/manganese button battery that's commonly used watches. They're well known as 157 batteries and are equivalent in size and voltage to the SR44 batteries. Later designs include silver oxide batteries and feature a capacity of approximately three times as long a charge at a higher price.
AG13 batteries feature a termination voltage of 0.9 volts and a standard voltage of 1.5V. They have a cell size of 11.6 x 5.4mm and a capacity of 130mAh. Moreover, the batteries work efficiently at temperatures of -10 degrees Celsius to +60 degrees Celsius.
Manufacturers often assign proprietary names and numbers to their batteries. For instance, the proprietary name for LR44 in some companies is the International Electrotechnical Commission (IEC) LR1144 battery. The letter "L" symbolizes the electrochemical system used, an alkaline electrolyte. The letter "R" indicates its cylindrical (round) cell, while 11 and 44 signify the battery's diameter and height, respectively.
An L1154 battery is a 1.5-volt alkaline button cell battery of the LR44 specification. They're cheaply available online and you get much more value for the money spent. However, alkaline L1154 batteries are not easy to find locally, as Energizer and Duracell dominate the battery button market in the US.
Just like LR44 alkaline battery, GPA76 batteries boast high quality and high reliability. This alkaline button cell battery offers long power life and suitable uninterruptible power sources for your device. It works well in both high and low temperatures and is widely used in alarm transmitters, calculators and sugar level detectors.
The Energizer 357/303 Battery
If you wish to power medical devices, calculators and watches, consider using the Energizer 357/303 battery. It's a long-lasting zero mercury specialized battery that boasts a nominal voltage of 1.5V. These are examples of silver-oxide batteries.
Alkaline Vs Silver-Oxide Batteries
There are several significant differences between these two chemistries. Alkaline batteries are more affordable than silver-oxide batteries. Silver-oxide batteries feature a nominal voltage of 1.55V while its counterpart boasts a nominal voltage of 1.5V. Silver-oxide batteries ordinarily have longer shelf-life than alkaline batteries.
Unlike alkaline batteries whose voltage drops over time, silver-oxide batteries have nearly constant voltage during the use. The battery capacity of alkaline LR44 batteries is approximately 110 mAh, while that of silver-oxide ranges between 165-170 mAh.
