For your safety, please do not open the batteries;...

  • Page 16: Operation Parameters

    Factors Influencing Capacity Battery capacity consists both of nominal capacity and actual capacity, for nominal capacities of the FT series battery please refer to Table 1-1. Actual capacity is the real quantity of electricity battery discharge under certain condition, it equals to discharge current multiplied by discharge time, the unit is Ah.

    Figure 3-2 service life and temperature curve --- SSP series Figure 3-3 Service life and temperature curve --- SP series Charge Floating charge Charge method: 2.27V/cell with limited current of 0.3 C (A). Charge voltage must be adjusted according to ambient temperature, temperature compensation coefficient is -3mV/cell/℃.

    Cycle application Charge method: 2.45V/cell with limited current of 0.25 C (A). Charge voltage must be adjusted according to ambient temperature, temperature compensation coefficient is -4mV/cell/℃. When charged capacity is about 105-110% of discharged capacity or in constant voltage case, the charge current must be kept unchanged for 3 hours in the final stage of charge., charge is ended.

    Operating Warning The batteries are already charged when delivered, and are fitted with a protective cap on  each terminal. They should be unpacked with care. Avoid short-circuiting terminals of opposite polarity, because these units are capable of  discharging at a very high current especially if the lid or the container is damaged. Unpacking the battery Each shipment is accompanied by a packing list ...

  • Page 22: Storage

    In parallel: The same battery may be connected in parallel to give higher current capability. This connection in parallel will be preferably carried out through an equipotential wiring for an equal current distribution in each string. There is no technical reason for limiting the number of strings, but for practical installation reasons, it is recommended not to exceed 4 strings in parallel especially if the battery is used in high discharge rates (standby time lower than 1 hour).
