Shelf life procedures
As batteries lose part of their capacity, during storage, due to self discharge.
Fiamm recommends FG range of batteries can be stored for 6 months at an ambient
temperature of 20 and 25 °C (see attached graph on reverse). Longer storage requires
a recharge. This should be carried out in line with Fiamm recommended method; 2.4
V/cell for no longer than 24 hours at 20 °C
