topcon unirex batteries

[odonoghue]

Just acquired a Topcon Unirex (had a few back in the '70s) and can't remember what bettery (ies) to use. Anyone out there can put me in the picture, so to speak?

Cheers,
Mike

The Unirex took PX675 Mercury batteries that are no longer available because of the potential environmental effects, but you can use Wein Cell MRB 675 Zinc Air batteries.

wrong information

Actually you've given the wrong info. I ordered the item as you suggested but I later found out that the one required was a PX625 equivalent
