Common causes

  • 1Natural chemical degradation of Li-Ion cells over time.
  • 2High electrical resistance due to oxidized battery pins.
  • 3Unstable input voltage from non-certified power adapters.
  • 4Physical displacement of the battery pack causing broken contact.

Solutions

Diagnóstico rápido

The BAT-01 error appears on the screen when the battery level is critically low or the charging handshake fails. Verify that you are using the correct power adapter (voltage match) and that the cable is firmly seated.

Solución paso a paso

  1. Visual check: Remove the battery and inspect the gold contacts for oxidization or dust build-up.
  2. Cleaning: Gently wipe the pins with a dry cloth or 90% isopropyl alcohol.
  3. Full charging cycle: Plug the unit into a wall outlet for 4 hours.
  4. Reset: Reinsert the battery until you hear a secure 'click'.

Prevención y mantenimiento

Never leave the battery fully drained for long periods. Use only OEM chargers to avoid erratic voltage delivery. Store the printer in a cool, dry place to protect the battery chemistry.

Cuándo llamar a un técnico

If the battery gets excessively hot during charging or the unit still reports BAT-01 after a 4-hour charge, the battery cells have likely reached the end of their lifespan and require replacement.
