LR48. Battery Details Page.

Do not confuse with these other batteries listed as "393":
LR41.

Do not confuse with the No8, the C size domestic battery or the F size 1.2 volt rechargeable.

There is no voltage compatable equivalent that I can find for the banned Mercury type except the Orange Hearing aid battery, which is unsutable for some applications due to little or no air reaching the battery once fitted (check your application). The Alkaline or Silver Oxide types should be fine for most applications.
