What does 200 mean?

The battery charger is configured with a technology setting that is incompatible with the connected battery's TagID. This prevents proper recognition and safe charging based on the specific battery chemistry and characteristics identified by the TagID.

Common Causes

  • An incorrect battery technology (e.g., lead-acid, Li-ion, NiMH) is selected in the charger's settings.
  • The TagID data from the battery specifies a technology type that is not supported by the charger or its current configuration.
  • Corruption of the technology identification data within the TagID module.
