Does anyone know the capacity (mAh) of the 82033 battery packs (4 x Sub-C cells) as used in Topcat calculators and 82143/82162 printers and 82161 tape drive ?
Thanks
John
I don't know specifically about the cells HP used, but IIRC, typical NiCd sub-C cells in the mid-1970s were around 1100 mAh.

Yes, that seems to be in line with this battery check procedure in the 82143A service manual.

A modern (rebuild) battery would be around 3 times as much, see e.g.
here (HP82033A).
Thanks guys, much appreciated.
