I started buying the flexible PCB, but didn't do such a good work on the assembly part!!! This kit avoid any misfortune...

upper screw heads where damaged so i have to order also the Piece for repairing HP41c back cases., anyway it's a good product !

TheCalculatorStore has taken a long time and performed a lot of testing to refine and make these HP41 repair and replacement products. They work as advertised and have helped me bring a few old and tired HP41s back to life. Thank you Jose and the rest of the team.

Very well made part, it fits perfectly and the calculator is running again. I use my HP41 very often and I am very happy about the repair that would not have been possible without this part. Many thanks to TheCalculatorStore.com for this great spare part.

Perfect replacement! I have used it multiple times for repairing different HP-41 types where there wre partially or even fully corroded batterie contacts and I could always restore full functionality with respect to battery contact as well as extension ports.

the product is ok but the wait time (more than a month) not

Not mounted, problem is the CPU

I bought my HP-41c new in 1982 and used it for a few years in school. The calculator stopped working years ago due to a couple of bad contacts. I recently decided I didn't want to throw it away after all these years so I I bought and installed the 'Assembly Kit for HP-41c battery bay and expansion ports' from The Calculator Store. Delivery took 2-3 weeks from Spain but installation was very straightforward and the calculator now works great.

It's fantastic that someone makes this replacement part fully assembled! (More details when I'm ready, since I'm recuperating from an operation. Also
it looks like more is broken on my HP41CV)
Thank you very much for now!

One of the battery contacts in my HP-41C was corroded, unfortunately, and could not be cleaned or restored to make reliable contact. I replaced the old part with the new assembly kit and it is a perfect fit. The device is restored to working order again, the battery and the modules connect properly to their respective contacts.
