|HP35 battery pack|
Message #1 Posted by Martin Mendelson on 8 Sept 2007, 2:38 p.m.
I have an HP35 the works fine with the AC adapter, but whose battery pack expired years ago. I still have the pack, and I wonder if anyone has a procedure to rebuild it with new cells that would recharge with the original AC adapter.
Thanks for any suggestions.

slice it open.
carefully rip out the old tabs.
nicad battery packs of the same configuration, made for cordless phones, can found at radio shack.
solder the tabs onto the new battery pack.
glue or tape the pack back together.
