Hi, Cell capacities have gone up. I'd buy four six cell (7.2V) 2500mAH model RC battery packs and break up as required. Smaller cells much cheaper and tags already welded.

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.
