![]() What Is The Difference Between LR44, AG13, And A76?Īs we have seen, the three battery types LR44, AG13, and A76, are interchangeable. None of these batteries are rechargeable, and it is dangerous to attempt to recharge them. The more expensive silver oxide versions have more consistent voltages over time and will typically maintain at least 1.2 volts. ![]() A standard alkaline battery’s voltage will reduce to around 1 volt through its working life. The significant factor here is how the voltage will drop during use. Voltage: 1.5 – 1.55 VoltsĪll types of this battery provide 1.5 or 1.55 volts output when new. They are more expensive than alkaline equivalents, so a balance can be found, depending on how the batteries are used. The downside of silver oxide batteries is cost. A silver oxide battery can last as much as three times longer than a similar alkaline version. However, because the AG13 and A76 designations are manufacturers’ part numbers, they can diverge from the standard.įor example, an AG13 type battery made by Energizer uses the silver oxide chemistry. The standard chemistry for these three battery designations is alkaline. The size is critical, as even a tiny difference and the battery will not fit many of the small devices it is designed to operate. To conform with international standards, any battery designed to be used in place of an LR44 should have a diameter of 11.6mm and a thickness of 5.4mm. The most obvious similarity is the physical size. Also, none of these batteries is rechargeable. Similarities between the LR44, AG13, and A76 include battery dimensions, chemistry, voltage. There are several similarities between the LR44, AG13, and A76 that make them interchangeable. Although they are the same size as the LR44, the internal chemistry used can vary, which will affect the battery life. The R44 code defines the standard physical size of this battery type.īoth AG13 and A76 are manufacturer’s part numbers for batteries that can be used in place of LR44 batteries. Batteries designated L will use alkaline chemistry to provide the power in the case of the LR44, it is zinc-manganese dioxide. There is not a simple yes-no answer to this question! The LR44 designation is an international standard, IEC 60086-3, defining the size and battery chemistry used. The battery capacity of alkaline LR44 batteries is approximately 110 mAh, while that of silver-oxide ranges between 165-170 mAh.Check Price Are LR44 The Same As AG13 And A76? Unlike alkaline batteries whose voltage drops over time, silver-oxide batteries have nearly constant voltage during the use. Silver-oxide batteries ordinarily have longer shelf-life than alkaline batteries. Silver-oxide batteries feature a nominal voltage of 1.55V while its counterpart boasts a nominal voltage of 1.5V. Alkaline batteries are more affordable than silver-oxide batteries. There are several significant differences between these two chemistries. These are examples of silver-oxide batteries. It’s a long-lasting zero mercury specialized battery that boasts a nominal voltage of 1.5V. If you wish to power medical devices, calculators and watches, consider using the Energizer 357/303 battery. It works well in both high and low temperatures and is widely used in alarm transmitters, calculators and sugar level detectors. This alkaline button cell battery offers long power life and suitable uninterruptible power sources for your device. Just like LR44 alkaline battery, GPA76 batteries boast high quality and high reliability. However, alkaline L1154 batteries are not easy to find locally, as Energizer and Duracell dominate the battery button market in the US. They’re cheaply available online and you get much more value for the money spent. The letter “R” indicates its cylindrical (round) cell, while 11 and 44 signify the battery’s diameter and height, respectively.Īn L1154 battery is a 1.5-volt alkaline button cell battery of the LR44 specification. 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. Manufacturers often assign proprietary names and numbers to their batteries. Moreover, the batteries work efficiently at temperatures of -10 degrees Celsius to +60 degrees Celsius. ![]() They have a cell size of 11.6 x 5.4mm and a capacity of 130mAh. Later designs include silver oxide batteries and feature a capacity of approximately three times as long a charge at a higher price.ĪG13 batteries feature a termination voltage of 0.9 volts and a standard voltage of 1.5V. They’re well known as 157 batteries and are equivalent in size and voltage to the SR44 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.
