Resolución de problemas
| Problema | Causa posible | Solución |
|---|---|---|
| Charger not turning on / No LEDs active. | No AC power; poor battery connection; severely discharged battery (below 0.5V). | Check AC outlet and power cord. Ensure secure connection to battery terminals. If battery is below 0.5V, it may be unrecoverable. |
| Charger stays in "Save" mode for extended periods. | Battery is deeply sulphated or damaged. | Allow the charger to continue. If it doesn't progress after 24 hours, the battery may be beyond recovery. |
| Battery not reaching full charge. | Incorrect battery type selected (not applicable for Ampmatic); internal battery fault; poor connection. | Ensure connections are secure. Have the battery professionally tested for internal faults. |
| Charger indicates fault (specific LED pattern). | Short circuit; reverse polarity; internal charger fault. | Disconnect immediately. Check for short circuits or reverse polarity. If problem persists, contact Tecmate support. |
