LR932 Vs. LR44

Though most consumers are familiar with AA, AAA, C and D batteries, LR932 and LR44 batteries are a bit more obscure. Nonetheless, these batteries lend themselves to many household electronic devices. Though LR932 and LR44 batteries are small, button-like cell batteries, they sport slightly differing specifications. Ultimately, neither one is better than the other; each battery's usefulness depends on each consumer's battery needs.

LR932 Specs

Tiny LR932 batteries, which measure only about .4 inch by .1 inch, are used in the construction of A23 batteries, each of which contains eight individual LR932 cells. These cell batteries feature flat base positive contacts, positive contacts on their casing and negative contacts on their raised tops. LR932 batteries feature alkaline chemical composition and have a nominal voltage of 1.5 volts and a capacity of 40 mAh.

LR44 Specs

LR44 batteries, like LR932 batteries, feature a button-like cell shape with a diameter of about .45 inchs and a height of about .2 inch. Also like LR932 batteries, LR44s are 1.5-volt alkaline batteries. However, these batteries have a capacity of 60 mAh. Unlike LR932s, LR44s are standalone batteries that are not typically used as part of any other sort of battery.


When used in 12-volt A23 batteries, LR932 batteries typically lend themselves to handheld RF devices, such as garage door openers and automotive keyless entry systems. More versatile standalone LR44 batteries are usually found in wristwatches, though they also lend themselves to clocks, calculators, cameras, digital cameras, PDAs, remote controls, blood and cholesterol testing meters, children's toys and other small electronic devices.


Though online and brick-and-mortar electronics retailers generally carry A23 batteries, LR932 batteries are not commonly available to purchase individually. As such, those on the hunt for LR932s will have to turn to do-it-yourself methods to extract the batteries from A23s, which retail for about $1 to $3 each at the time of publication. Like A23s, electronics retailers usually offer LR44 cell batteries. At the time of publication, these batteries typically sell for about $1 each.
