HP 41C, CV, CX Rechargeable Battery Pack Rebuild
Rechargeable battery pack 82120A
You are bidding on a full repair of your beloved Coconut and Halfnut HP-41C, CV and CX calculator rechargeable battery packs.   I have repaired many of them over the last 25 years.
I’m good at the following:
1)
Removing and replacing the original battery cells
2)
The case is NOT split, so the unit fits perfectly back in your calculator
3)
I use 1/3 AAA NiMH cells which are a little smaller than the
originals
but work well.
I’m not good at the following:
1)
Rebuilding the internal IC circuits if corroded
2)
Overcoming extensive battery clip corrosion.  They have to be "springy" to function
Shipping is at your cost and is generally inside the USA and often for international customers.
I will guarantee my repair for 90 days, and if it seems unfair to you how I fixed it,  I will refund your via PayPal, but I need to see pictures and explanations of what went wrong and how it is not operating as you want.  I need to learn too if I made a mistake.  I will re-fix it for you if you want for only shipping costs.
I have other auctions for HP calculators: Different battery packs, Orings and instructions, USB charging cables and Stand-alone charging boxes  if you search on Ebay for waterhosko
Shipping:
Shipping costs are listed below.  For multiple battery pack purchases contact me for actual shipping costs.
I will refund your extra shipping charges and only charge you actual shipping costs.
Also check my other HP calculator battery packs.
Hope to add you to my list of satisfied customers.
Sincerely,
Mark Hoskins
