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.
