Not wanting to labour the point, but just to be sure as I don't recognise that part number, in the 80s GE did make cylindrical sealed lead acid cells under the brand name "Cyclon" and these looked very similar to Ni-Cads. If the cells themselves aren't clearly marked one obvious check is the charging circuit, basically constant voltage for lead acid and constant currrent for Ni-Cad.

Charles, The NiCd pack (of five 'units', side by side, with each 'unit' being two 1/2 D cells stacked on top of each other) is 12 V 2.2 AH, GE Cat. No. JF 479147 8249. I suspect the '8249' is a date code and they look original. The Cal date was also Feb 82. I found 1.2 V 2.5 AH 1/2 D cells for $5.50 ea. On the internet. I would like to find a cheaper source since I need 20 of them, enough for two packs, one pack on each side of the Battery PCB. I'll also need some 'thin' heat shrink tubing to go around the 2 cell 'units'. I could also use some 'spare' 1/2 D cells for the battery packs in my 5061A's and B's. I wonder what would be better, SLA or NiCd's? The NiCd's had 'spewed' and corroded the PCB a bit but I have that cleaned up. I have seen SLA's (in UPS's) 'shrivel' and get very hot as they die. I'll have to take a look at the 732A manual to see what it's battery construction looks like.

If so, do they look original? The 732A uses SLA batteries (originally 4x 6v, but most folks replace them with 2x 12v). If it has SLAs or gel cells (or originally did), you should replace them with the same so the charger works properly.
