Hearing aid devices use such batteries since they have low voltage however they possess the exceptionally good capacity. Different chemistry for batteriesīatteries with mercury oxide have low voltage with good capacity however they are not used nowadays. They are different sizes and will not work in place or each other. However, there are dozens of brands and model number that are all equivalent to the lr44 or AG13 battery.Īll of these batteries are interchangeableĬlick on the item Link Below to be taken to Amazon pages for each itemĮnergizer LR44 / AG 13 Replacement Batteryĭifferent manufacturers have different part numbers. The most common equivalent battery to the lr44 is the AG13 battery. The height of the cell is 5.2 ± 0.2 mm and diameter ranges from 11.4☐.2mm.Īlternatives to this battery/ lr44 compatible batteries The shape of the cell is round or cylindrical which is defined by R44. It has Zinc as a negative electrode, manganese dioxide is a depolarizer and a positive electrode and it has an alkaline electrolyte. So, the nomenclature for LR 44 battery is “L” indicates the type of electrode used in it. IEC or the international electro technical commission defines the nomenclature of a battery. Hence, select the right cell that has a better life and stability. Same size cells with different chemistry are interchangeable.Īs different cell comes with different chemistry so their voltage stability and service life also differ. ![]() Materials such as cupric oxide, carbon monofluoride, silver oxide, manganese dioxide and oxygen from the air are used as the common cathode. Zinc or lithium is the common materials as the anode. They have long service life however some of them discharged on their own but slowly if they are not used. These are primary cells which are usually disposable and not chargeable. The top cap of the cell is negative terminal which is insulated. The positive terminal and body of the cell are made from metal. It resembles a button hence called a button cell. They are squat cylinder type of cells that have a diameter ranging from 5 to 25 mm and are 1 to 6 mm high. LR44 Battery is made up of several small single cells called a button cell. Here, we will discuss the performances, chemistry and equivalent battery LR44.įind the battery replacements you are looking for Below The voltage capacity of a battery depends upon the manufacturer.īutton batteries are very dangerous to children. These batteries come in zinc-air, silver-oxide, alkaline and mercury oxide chemistry. The chemistry in these batteries exhibits different performances. LR 44 also called an A76 or AG13 has several equivalent names and comes in different chemistries. Some times these are a pain to find like the small button cell batteries The 1 5v LR44 battery is commonly found in the LED flashlights, calculators, calipers, clocks, cameras, digital thermometers, laser pointers, toys and even in a multimeter. We all know it, the electronics we love have batteries and those batteries need to be replaced. ![]() LR44 battery, equivalents, and its installation.
