The battery adopts high-performance positive and negative active materials, improving the charging efficiency of positive and negative electrodes, reducing the float-charge voltage of the battery, under the lower float charge voltage. Nickel-cadmium is equally dependable in controlled city environments or harsh, unpredictable conditions in the world’s most remote and unpopulated areas. It has high tolerance to rough handling and mechanical abuse due to strong components and robust construction. The EverExceed nickel-cadmium block battery’s unique electrochemistry enables it to regularly withstand any depth of discharge. Following a deep discharge, the block battery is designed to recharge very quickly and economically, using standard single or two-level charging equipment.

Nickel-cadmium block batteries are quick and easy to install as original equipment and may be stored for many years in a discharged state under correct conditions. They adopt “valve-regulated vent plug technology”, therefore, the water consumption is low, the electrolyte is rich. Within the service life, the battery top-up time is up to 3~5 years due to EverExceed excellent valve-regulated feature. They offer up to 20+ years of completely faithful service with no replacement cost and no downtime. They also have a wide operating temperature range, generally operating between temperatures of -40°C to +60°C, they can tolerate extremes of -50°C to +70°C for short periods.

  1. Protective cover: To prevent external short-circuits; In line with EN50272-2(safety) with IP2 level;
  2. Plate groups bus: Connects the plate tabs with the terminal post; Plate tabs and terminal post are projection-welded to the plate groups bus;
  3. Plate: Horizontal pockets of double-perforated steel strips;
  4. Cell container: Material: translucent transparent polypropylene;
  5. Flame-arresting vents: Material: polypropylene;
  6. Plate tab: Spot-welded both to the plate side-frames and to the upper edge of the pocket plate;
  7. Separating grids: These separate the plates and insulate the plate frames from each other; The grids allow free circulation of electrolyte between the plates;
  8. Plate frame: Seals the plate pockets and serves as a current collector.
