Recommended battery pack for HP-19C?
A tedious Google search revealed that 4-AA NiCad battery packs for the Sting Series calculators (HP-10 and HP-19C) are available online from multiple sources, but they all seem to be $50 or more, which seems excessive, and I don't know which sources are reliable. Yes, I know that I can rebuild the ones that I already have, but I'd like to also buy some more as spares.

If you have purchased a Sting battery pack online, please share your impressions of it, and your source, and the price you paid. Thanks in advance!

I've replaced all my Classic battery packs with AAA adapters from Mark Hoskins <waterhosko@aol.com>. I can now use AAA alkalines or Eneloops and I'll never need to rebuild a Classic battery pack again.
I'd ask Mark if he can make a 4-cell version for the Sting series, or make one yourself from a plastic 4-cell AAA battery holder.

Thanks, Dave. I did write to Mark, and he replied promptly that he does not have any Sting Series battery packs, but graciously offered to rebuild any which are sent to him. So I'm hunting for either new ones or a 4-AA holder that can be converted into a Sting Series pack.

Meanwhile, I stopped at Batteries Plus today and bought 4 NiCad AA flat-end cells, 1100 mAH for only $1.29 each. Sweet.

Stumbled on this a few days ago...

RE: Recommended battery pack for HP-19C?
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~

When original battery case is still around you can easily open it and insert following cells

http://www.ebay.de/itm/Akku-Pack-im-Poly...Swn-tZEihc

with a little bit DIY work. Higher capacity, LSD feature and still can be charged with geniue wallplug charger.

Sorry, I do not know a source on other side of atlantic ocean.

Nevertheless mentioned professional seller can be highly recommended, too.
