  • Notes

  • Developed in June 1939 as the “A” battery for 1.4-Volt Portable radios in conjunction with the PR45 “B” battery.

    The "A" battery, type number PR8, is a 1.4-volt wax top dry battery fitted with screw terminals.

    Approximate service life is as follows: -

    Initial Drain, mA Useful Service Life, hours
    200 300
    250 220
    300 170

    It should be noted particularly that these figures are approximate only. They are based on a minimum useful voltage of one volt, though very good results have been obtained from 1.4 volt valve receivers, using an "A" voltage of only 0.8 volt.

    Redesignated to Type 741.
