Highly efficient power supply and backup power supply solutions to telecommunications, information and industrial technologies.


Batteries FIAMM Endurlite OPzS Bloc

 Technical Features

Tubular positive plates with special low < 2% antimony lead alloy reduces loss of water (3-year topping-up intervals on float condition)
Active material contained in polyester fiber gauntlet ensures extended long life
Electrolyte: high purity sulphuric acid solution with 1.24 specific gravity at 20°C
Pasted negative grid plates designed to have service lives consistent with the positive plates
Separators with extremely high porosity and low internal resistance
Container in impact and acid resistant SAN, designed for unsurpassed mechanical strength.
Translucent container for easy maintenance.
Lid in opaque SAN, sealed to the container.
Threaded female M10 terminal posts guarantee highest conductivity, maximum torque retention and easy installation
High integrity post seal design to prevent electrolyte leakage and terminal corrosion
Ceramic plugs filter electrolyte from escaping gasses
Flame arrestors prevent errant sparks or flames from entering the battery (flashback) Storage: < 3% self-discharge per month at 20°C allows 6 months shelf life Installation in vertical position
Flexible, fully insulated cable connectors with insulated screw with probe hole on the top for electrical measurement
