following during storage period:
5.1
The self-discharge rate is related to the ambient temperature. The degree of
self-discharge is smaller when the ambient temperature is lower, otherwise it will
be larger. The required temperature for Narada batteries’ storage is 5ºC to 30ºC.
The storage place must be clean, ventilated and dry.
5.2
An important parameter in storage is open circuit voltage, which is related to the
density of the electrolyte. In order to avoid permanent damage to the plate caused
by self-discharge, the batteries should be recharged as storage period shown in
following table. The equalization charge method should be adopted.

5.3
During storage, if the open circuit voltage is lower than 12.6V/block, the batteries
should be recharged before usage. The equalization charge method should be
adopted.
5.4
All batteries should be fully charged before storage. It is recommended to record
the storage time in the periodic maintenance record and to note down the time
when the next necessary recharge should be carried out.
