General Features
Higher Reliability and Quality
Throughout the whole manufacturing process, PPM and ISO 9001 are carried out to make sure that the product reliability and defect ratio meet with the PPM standard.
Higher Power Density
A special assembly technology is used to enhance power density to a considerable level.
Reliable Construction
The extra strong construction ABS container reduces case bulging and plate warping, ensuring long life and high performance.
Valve regulating
Perfect venting system, which operates under low pressure, is designed to release excess gas and keep the internal pressure within the optimum range of safe and efficient performance.
Excellent Recovery from Deep Discharge
Unique technical processes are used into the grid alloy and electrolyte additives, so that the battery can be recharged easily to a normal level even after being over-discharged.
Living Up to Prevailing Standards
The batteries live up to standards JIS, DIN, BS and IEC.
Construction
These reactions can take place only by using :
Plates composed of special alloy with several components which provide the plate grids with high
mechanical strength and a high level of hydrogen over voltage.
An appropriate ratio between positive and negative
active materials.
Fiberglass separators manufactured from borosilicate, giving them excellent resistance to high temperatures
and to sulphuric acid. The high level of porosity of these separators is used to retain the quantity of electrolyte necessary for cell operation, but without any free electrolyte.
A pressure relief valve which allows gas to be released
if necessary in the case of an accidental overcharge.
Charge Characteristics
The cells in the VISION FM product range must be charged at a constant voltage at an ambient temperature of 20oC, the batteries should be charged at 2.27-2.30 volts per cell. It is not necessary to limit the current, as this will be governed by the maximum output available from the charger until the voltage limit is reached. The charging voltage of 2.27-2.30 volts should also be used for float charging. To achieve nominal performance characteristics, it is recommended to adjust this value to suit the ambient temperature, as indicated in the following table: Under these conditions a full recharge will be completed in approximately 48 hours.
Fast recharge:
Increasing the charge voltage to 2.40 Volts per cell can reduce recharge time and it is possible, depending on the depth of discharge, to halve the recharge time. Under these conditions, however, the charge must be monitored and must be terminated when the charge current remains reasonably steady for 3 hours
after the voltage limit has been reached. At the beginning of charge the current must be limited to 0.3C10 (A).
Ripple current:
The ripple content of the charging current affects the life of the battery. It is recommended to limit the continuous ripple current to 0.05 C10 (in amperes) as recommended value (never exceed 0.10C10). Transient and other ripple type voltage excursions can be accommodated provided that, with the battery disconnected, the system peak to peak voltage including regulation limits falls within 2.5% of the recommended float voltage of the battery.
