- Notes
-
Contains 8 x F cells in parallel in one row. About 68,000 to 80,000 mAH depending on load, or over 250 hours on a 300mA 5 tube Battery Radio, perhaps close to 300 hours on a 250mA 4 tube set, certainly over 240 hours on a 250mA set. Life depends on prior storage quality of cells, operating temperature and load (internal resistance means duration isn't linear with load).
Connector on one of the small sides is common type 1.5V. (small and fat pins at smaller spacing).
The first USA "All Dry" Radios used Sylvania octal tubes in 1938.
