Which charger is best to use?


Unfortunately many unapproved and therefore cheap chargers are available on the market. These chargers recharge battaries only partially. A good charger complies with the following properties:

  • Fast charging:
    It is often desirable that NiCd batteries are fully charged within 1 to 2 hours. Given the composition of NiMH batteries, fast charging is not recommended within this amount of time. Chargers made specifically for these NiMH cells need at least 3 to 4 hours to fully recharge these batteries.
  • Automatic charging flow:
    It is important that chargers have a built-in checking system for the desired current of a particular battery type.
  • Protection against overcharging:
    Good chargers have an automatic built-in timer or electronic control system that prevents overcharging batteries when they are fully charged. Overcharged batteries become hot and thus the valve pops from the battery casing. In addition, overcharging batteries damages the internal system.
  • Trickle charging:
    After the charging process, the charger should be able to switch to trickle charge. This ensures batteries stay fully charged when staying put for several days/weeks in the charger. The self-discharge is then offset by the extra energy the charger generates.
