Deutronic DBL800 battery charger

The Deutronic DBL800 is an 800‑W intelligent battery charger designed for automotive starter batteries (lead acid, AGM, gel, VRLA, and lithium‑ion) with full on‑board safety and airbag compatibility. Common failure points in this class include damaged input power circuitry, firmware corruption or misconfiguration, and degradation of internal protection relays (short‑circuit, reverse polarity, over‑temperature). First‑check diagnostics: verify mains voltage and connector integrity; confirm the unit’s firmware version matches the model specification and reset to factory defaults if needed; inspect for blown fuses or tripped protection relays and review any error codes displayed on the LCD.[oss-gpt-20b]
