Notes
- IEC prefix for alkaline is L, thus a "Lady" cell is actually always LR1 as only Alkaline version now
- The 7.5V Round 90AH Zinc Air "fencer" batteries have 5 off Zinc Air based "Flag" type cells. See also Type "O" cell
- Exact capacity depends on load used and end point (1.1, 1.0 or 0.9V). Quoted capacities are for 1V to 1.1V end point approximately. Thus a B Cell capacity is higher for 10mA HT than 50mA series LT.
- Normally cell/battery dimensions include the terminal(s). The ANSI cell heights in some documents appear to be excluding the top connection "pip"/cap/terminal.
