I've got an older Philishave model 980 electric razor. The rechargeable batteries have finally decided they don't want to play any more but they have no external markings on their cases. The cct board says use only 4822 138 10334 replacement. After googling this I found a bunch of sites in languages I don't know. I think I am being shown the batteries are 1.2V 600mAh nickel cadmium (2 batteries so total voltage would be 2.4V). Am I reading these other sites correctly for the values and if so I should be able to use any nickel cadmium with specs like these shouldn't I? If I threw in a couple of 1.2V
1200mAh I would still be good for a longer held charge? TIA.Cheers, Lawrence
