Fonctionnement : Chargement et utilisation
To maximize the performance and lifespan of your DGFTB battery, follow these operating guidelines:
- Cycle de charge initial : For the first 3-4 uses, fully discharge the battery to approximately 5% (avoiding 0%) and then charge it completely to 95%. This helps calibrate the battery for optimal performance.
- Chargement régulier : Connect your LG CordZero A9 vacuum with the DGFTB battery installed to its charging station or adapter. The charging indicator on your vacuum will show the charging status.
- Évitez les surcharges : While the battery has built-in overcharge protection, it is generally good practice to disconnect the charger once the battery is fully charged if not in use.
- Utilisation optimale : The battery is designed for consistent power delivery throughout its discharge cycle, providing reliable operation for your vacuuming tasks.

Entretien
Proper maintenance can significantly extend the life of your DGFTB replacement battery:
- Nettoyage régulier : Veillez à ce que les contacts de la batterie restent propres et exempts de poussière ou de débris. Essuyez-les avec un chiffon sec si nécessaire.
- Contrôle de la température : Store and operate the battery in a moderate temperature environment. Avoid extreme cold or heat, as these can degrade battery performance and lifespan.
- Stockage à long terme : If storing the battery for an extended period, charge it to approximately 50-60% capacity. Store it in a cool, dry place. Avoid storing a fully charged or completely depleted battery for long durations.
- Cycle Management: Periodically perform a full discharge (to 5%) and recharge cycle to help maintain battery health, especially if you notice a decrease in run time.
Dépannage
If you encounter issues with your DGFTB replacement battery, consider the following:
- La batterie ne charge pas :
- Ensure the battery is correctly seated in the vacuum and the charging dock/cable is securely connected.
- Vérifiez que la prise de courant est fonctionnelle.
- Vérifiez si la batterie ou le chargeur présentent des dommages visibles.
- Try re-inserting the battery to ensure a proper connection.
- Durée d'exécution courte :
- Perform the initial charge cycle recommendation (discharge to 5%, charge to 95%, repeat 3-4 times) to calibrate the battery.
- Assurez-vous que la batterie est complètement chargée avant utilisation.
- Operating the vacuum on high power settings will naturally reduce run time.
- Battery capacity can degrade over time with extensive use.
- La batterie ne tient pas la charge :
- This could indicate a defective battery or an issue with the vacuum's charging system.
- Ensure proper charging procedures are followed as outlined in the 'Operating' section.
- If the issue persists after following all troubleshooting steps, contact customer support.
