Thanks.
Watched the 34970A slowly die and set it aside until I could afford a replacement.
As I recall, factory wanted $850 for replacement and a tech rental shop was offering $750 w/ 34902A earlier this year.
Somehow the other day ended up here.
Battery voltage read 0.15V.
Under $10 for new battery from Mouser.
Un-soldering w/Pace station.
Tip touched round hole next to pin and spark blew all the solder out around terminal.
Ohmmeter readings show that that hole is connected to the terminal?

Like the + terminal is connected to its close hole.
Judiciously replaced the battery and back in operation.
