Recommended battery pack for HP-19C?

[jjohnson873]

Joe...I was looking for the same thing, an HP-19c battery pack. I decided to bite the bullet and purchase the eBay pack at vintagecalculatorsinc for $49. It's a very high quality, 3D printed case with 4 Tenergy 1000mAH NiCd batteries. The pack fit perfectly in a recently acquired HP-19c. I have access to a 3D printer, so I may be looking for the SLA files and print the battery case myself. But then I'll need to find a source for the springs. ~ Jim~
