4.3.2 Storage of the battery
In case of extended storage, when the delivery includes maintenance free batteries, keep in mind
that they are subject to auto-discharging process
To avoid permanent damages to the battery, you must observe the following instructions:
• The storage time without charging the battery depends on the temperature of the storage
ambient.
• The optimal ambient temperature for the batteries is 20°C (68°F).
For storage temperature higher than 20°C (68°F), the storage time will decrease.
• Each additional 10°C (18°F) over the nominal temperature of 20°C (68°F) will decrease the
storage time, without freshening charge, by half.
In case of a maintenance free battery, the storage time without charging the battery is
approximately:
6 months with storage temperature 20°C (68°F)
3 months with storage temperature 30°C (86°F)
2 months with storage temperature 35°C (95°F)
