Radio Battery AD14

LT battery for the Ever Ready Model N and N3.

It would have lasted about 120 hours in N and more than 240 hours in N3 as it was probably 6 x D cells in parallel, Almost exactly three times size of 2 x cell AD35. However 6 x D Cells is approximately the capacity of an AD4 which uses 4 x F Cells. The Pack would need to be a minimum of about 196 x 34 x 92 mm to accommodate F-Cells, one price list has it as 3¹/8" (about 80mm), if it was 3⁵/8" (1 typeset instead of 5) it would be F cell based. The N & N3 will accomodate a taller pack with F cells (180 to 220 hours for N or 360 to 440 hours for N3).

Earlier versions are called "ALLDRY Radio Low Tension Battery"
