I'm using 1.5V 357 watch cells in my 15c and they work just fine. The manual (for the 15c) calls for A76, LR44, or 357 cells.
I'm sure all the voyagers use the same batteries.
Best regards, Hal

Hi;
newer HP12C and all HP12C Platinum use a single 3V or 3.3V button type cell. You can see which is yours by removing the battery cover.
My newer HP12C and 12C Platinum use a Panasonic CR2032.
About suppliers, I guess that you can find them easily, wherever you are. Any electronic components supplier should have these for sale.
Cheers.

I am using A76 (energizer) and LR44 (Maxell). Walgreens or a good camera store, or google it and there are jillions of sites.
Good luck
