Stationary batteries

Advantages

• Refilling of the water only every 3 to 5 years in float charge use, under normal conditions
• Longer battery life: 15 years in float at 20°, even in cyclical use
• Flexible screwed connectors:
  • simple and easy connection
  • less accessories demanded
  • less time for maintenance & control
  • reduction of the tension is smaller in the connections
  • better protection against short-circuits
• Self-discharge less than 3 %
• Very low floating current
   

Main ranges of application

Thanks to the OpzS stationary battery series, we can offer a reliable and environment-friendly energy source for back-up systems for innumerable applications, such as: telecom business, the railways, electricity cabins, uninterruptible power supplies, ups, electricity and nuclear power plants, wind and solar energy etc.
 

How do I order a stationary battery?

• Type and reference of the battery
• Voltage & AH of the battery
• Size of the outerbox of the battery
• Lead-acid / AGM or GEL

When this data aren’t available, we need following information:

Dimensioning of the battery:

Parameters:

1. Which capacity in (K)watt or which constant current
2. Nominal tension of the battery (12V, 24V,...)
3. Autonomy
4. Minimal final tension
5. Ambient temperature (if possible). Use the discharge tables (constant capacity per cell, or constant current) per final tension per autonomy.

E.g.:

12V, 240 watt, 1 hour:

Capacity per cell = 240 / 6 = 40A

When you take 1,75V/cell as final tension for 60 minutes

Choice: DAS12-33: 40,3 watt or DAS 12-44: 53,3 watt.
