WHAT DOES RESERVE CAPACITY MEAN?

RC IN MIN - TECHNICAL TERMS EXPLAINED SIMPLY

Back to overview

The reserve capacity is the capacity reserve that the battery can supply within minutes in the event that the alternator fails, there may be just enough power for you to get to the nearest garage. However, it depends on the electrical consumers in the car.

IEC (International Electrotechnical Commission) schedules the following test:

Discharge with 25A up to a final voltage of 10.5V at a temperature of 27 °C. (5.25V with a 6V battery)

 

Time measured in minutes = Reserve capacity

 

25A is the typical electrical load for a car under normal operating conditions. In this way, the reserve capacity provides information on how long a vehicle can continue driving with a normal electrical load and a defective alternator or broken V-belt.

 

Banner tip

The more electrical consumers you switch off, the further you’ll be able to drive the car, of course.

Banner Lexicon: Carbon Loaded

What does it mean if the phrase “Carbon Loaded” is added?

“Carbon loaded” technology enables better charging of the battery thanks to the integration of carbon additives in the negative active material. Using this material, with its comparatively low weight, makes it possible to achieve significantly better charging and higher cycle stability.

Banner Lexicon: cycle capacity

What does cycle capacity mean?

A battery (accumulator) always works between charging and discharging (= cycle). The more often these so-called cycles are possible, the more cycle-stable the battery is.
