Battery charger indicator is off, and the battery is gradually discharging between tests.

Safety first: Isolate the AC supply before opening the charger cover.

• Verify AC feed: Check that the charger input breaker or fuse in the Aksa panel is ON and that mains power is present.
• Inspect charger LEDs/meters: If no indicators are lit with AC present, the charger may have failed.
• Check DC output wiring: Ensure correct polarity and tight connections at the battery.
• Replace charger: Fit an Aksa-approved charger with the correct voltage and current rating.
