You will need to use the serial number to select  the correct battery from the chart below this line. You can source the battery from an online vendor or perhaps even at a  CVS drugstore.


HP 12c (All serial numbers below CN11500001)*
1.5-volt button-cell
Duracell PX76A/675A
Panasonic LR44
11c, 15c, 16c, 42s, 32s, 17b
HP 12c (Beginning with serial # CN11500001), HP 12c platinum and prestige series
3-volt CR2032
