  1. All your devices that carry 6V/12V typical lead-acid or lithium batteries, including motorcycles, passenger cars, SUVs, trucks, ATVs, PWCs, boats, etc.

  2. Sigma battery chargers will automatically remember the last selected mode after a power outage and return to this mode in next use. This memory function covers 6V, 6V AGM, 12V, 12V AGM, and 12V lithium modes, 12V repair and 12V loading modes are not included.

  3. With HULKMAN Charging Technology, Sigma battery chargers will optimize the battery performance to some extent, which depends on aging and damage degree of batteries.

  4. Sigma battery chargers know batteries status by dynamic battery tracking and then output appropriate voltage and current the batteries need.

  5. “360°” is a figurative description of multi-dimension diagnosis based on voltage and current.
