The battery needs an equalization charge floating operation over three months, and the voltage
of at least two batteries are lower than 2.18V. The method of equalization charge is suggested
as follows: Charge with 2.35V/Cell for 24 hours, limiting 0.1C10A~0.2C10A, when the
average voltage raise to Equalization voltage, charge by Equalization voltage for 24hours.
z Charge
After discharge, the batteries should be charged in time. The method is recommended as

Whether the batteries are fully charged can be decided according to any one of two standards
as follows:
1. See following table, table3-3 is in different discharge, the time need for 0.1C

2. On condition of constant voltage, the value of charge current hasn’t varied for
continuous three hours.

5. Storage
All gel batteries experience self-discharge in open circuit. The result is that the voltage of open
circuit is decreased, and the capacity also decreased. During storage please note:
— The self-discharge rate is related with ambient temperature. The self-discharge degree
is smaller when the ambient temperature is lower, otherwise is larger. The requirement
temperature of Narada EosG batteries’ storage environment is from 0℃ to 35℃. The
storage place must be clean, ventilated and dry.
— An important parameter in storage is open circuit voltage, which is related with
density of electrolyte. In order to avoid permanent damage to the plate caused by
