Are button batteries AG33 and LR44 the same battery?
The AG33 battery, also known as the LR44 battery, is an alkaline zinc-manganese button battery. The button battery is marked differently in different countries, so the name is different but the battery parameters are the same. Other names of AG33 are LR44, 357, SR44, A76, LR1154.
There are several types of common button batteries according to their chemical composition: carbon, alkaline, zinc-silver oxide, zinc-air, lithium-manganese dioxide, nickel-cadmium rechargeable button batteries, nickel-metal hydride rechargeable button batteries, etc. According to the shape, there is a distinction between monomer and stack.
application
Button batteries are widely used in various miniature electronic products due to their small size, with diameters ranging from 4.8mm to 30mm and thicknesses ranging from 1.0mm to 7.7mm; they are generally used as backup power for various electronic products, such as Computer motherboards, electronic watches, electronic dictionaries, electronic scales, remote controls, electric toys, pacemakers, electronic hearing aids, counters, cameras, etc. Button batteries are also divided into two categories: chemical batteries and physical batteries, and chemical batteries are the most commonly used.
