Very well made
from John on 8/14/2022
It is made with excellent quality and craftsmanship. I was very pleased when I received it.
Many thanks!
Could be closer to the original
from Chris Meyers on 7/25/2022
My calculator works now, but not perfectly. There seems to be some foam strip under the contacts that make them convex shaped instead of flat, like the original. The convex contacts make intermittent connection and when I screw the case halves tight, it looses contact with the board.
Great! Works perfectly
from Michael on 7/21/2022
Perfect fit / perfect function / machine working in accordance with manufacturers specifications
excellent
from Ed on 6/10/2022
love fixing old HP calculators, and finding someone who has invested the time and energy to make the parts that are no longer available was great!
Better than expected, works perfectly
from Gerry Maynard on 5/15/2022
This helped me turn a box of parts back into a working HP-41C from 1982. The quality of the part was a pleasant surprise, and it works flawlessly. It was carefully packaged, shipped quickly and is exactly as described. Top-flight seller I'm happy I found, and I will definitely be coming back. Buy with confidence.
Probleme bei dem Einbau
from DimoG on 4/14/2022
Schnell geliefert.
Bei dem Einbau sollte ich die Bohrungen nachbohren,
weil sonst die Schrauben nicht durchgeführt werden konnten.
Naccher hat alles perfekt funktioniert.
Perfekt fit
from Lars Fredriksson on 3/19/2022
not cheap, but excellent!
from Klaus on 3/8/2022
Very good replacement part! Made my 41 CX work again!
Excellent product!
from Rick on 2/27/2022
This was a perfect form and function replacement for my original battery bay / expansion ports module. I'm extremely pleased with the product as well as the speed of shipment (shipped from Spain to the Midwest US in about a week). This is an A+ vendor and a great find for us vintage HP enthusiasts!
Perfect!
from Ari on 12/30/2021
The module is very well made and saved my poor 41C. The installation was largely problem-free, with the only issue being that 40 years of grime had practically glued the old module in place. The instructions saved my sanity - it really was just a matter of patiently getting it unstuck.

I'm really, really pleased. Thanks!
Muy bueno

from Jens on 12/12/2021
Easy to replace, it just fits instead of the original battery holder.
Excellent
from Mark Richards on 10/6/2021
Very easy to install and works perfectly. Restored my precious HP41, which I have owned since early 1980, to full function. THANK YOU Jose for offering this important part.
Excellent
from Leon on 8/25/2021
Very easy repair. I should have done this sooner. I’m glad you guys took the time to tool up and produce these repair parts.
Perfect!
from Thomas on 7/29/2021
Easy installation, my HP41CX is alive again.
Worked perfectly
from Hart on 4/27/2021
Although it took 3 weeks for the package to arrive in Reno, NV from Spain, it was well worth the wait because it worked like a charm. I downloaded the instructions and the replacement part was surprisingly easy to change out. My early 1980's vintage HP41CV started up immediately. Thanks!
Great
from rolpat on 2/27/2021
Based on the description it was quite easy to exchange the part. Take care when loosen and tighten the screws, since they go into plastics which is in my case already 35 years old. Now everything works again.
I was able to restore my HP-41C I couldn't find anyelse to do the repair.
from David E. Hendrick on 2/13/2021
The module was easy to install once I opened the case.
The extra screws I bought helped also. The computer is now functional and I am entering my Astronomy program into the HP-41C "Setting Circles for Dobsonian Telescopes."
Perfecto
from David Garcia on 1/27/2021
Perfecto en calidad, plazo de entrega y factura.
Totalmente recomendable.
Perfect in quality, delivery time and invoice
Exactly what expected
from CELMA on 1/5/2021

from Piero Zaccaria on 12/14/2020

excellent
from Charles on 11/29/2020
perfect fit for the repair of my damaged battery bay and expansion board, also purchased new feet as the old ones were breaking down
Excellent
from Anonymous on 11/27/2020
I found that even properly installed, the adhesive on the flex adhesive-only retrofit would let go causing anomalies in operation. This retained flex design has started nicely stable. Time will tell if it approaches the quality of the HP design. I am optimistic that it will.
Excellent
from Neil on 11/20/2020
The part arrived within a week and worked perfectly. Was an easy and quick fit as all four case screws came out without damage to the plastic posts. I can now use the 41CV's expansion ports again as the original part was damaged by a battery leak. My fault for not checking them for ages.
1st class spare part
from Anonymous on 8/10/2020
Part was foreseen for a HP 41 CX. Calculator is working again by 100%. Excellent !! Will order for further repairs this part only.
Very good
from Olaf on 5/9/2020
Bought my HP41C in 1980 and it worked till 1,5 .years ago. Corrosion distroyed the battery contacts. Replaced it now with the assembly kit. The whole work was dony within some minutes and the device works great again (also with many different modules). Thanks a lot, great job.
As good as the original
from Michael Markowski on 3/18/2020
I ordered this because I wanted to spare myself the agony of assembling the flex PCB to the module, and I'm glad I did. This worked great in my 40 year old HP-41C fullnut calculator and now it will last another 40 years with brand new battery contacts!
Perfect
from Kurt on 3/6/2020
very good spare part. Insert and the calculator works perfectly.

from Greg Bolt on 8/22/2019
Great product, helping us to keep these classics alive.
Perfect fit
from Christof Ullwer on 2/8/2019
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.
top notch
from Lars A Grønningsæter on 1/31/2019
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!
Good experience with the Assembly kit for battery bay and expansion ports
from Clay Fisher on 12/15/2018
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.
Product OK, a bitter long to receive
from Guarisco Fabrizio on 10/31/2018
Not mounted, problem is the CPU
Product OK, a bitter long to receive
from Fabrizio on 10/16/2018
the product is ok but the wait time (more than a month) not
Perfect
from Anonymous on 8/12/2018
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.
Perfect
from Avery on 6/18/2018
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.
Excellent
from Anonymous on 2/13/2018
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.
