Operating Instructions
The OptiMATE 2 operates automatically once connected. It features a 4-step charging and maintenance program.
- Automatic Charging: Upon connection, the OptiMATE 2 will automatically assess the battery's condition and begin charging at a constant current of 0.8A.
- Maintenance Mode: Once the battery is fully charged, the OptiMATE 2 transitions into its unique OptiMate maintenance mode. This mode alternates between 30 minutes of charging and 30 minutes of rest, ensuring the battery remains at 100% readiness without overcharging. This cycle also provides power to vehicle electronics like onboard computers or alarms.
- Long-Term Connection: The OptiMATE 2 is designed to remain connected to the battery for extended periods, even months, without risk of overcharging or damage. The battery will remain cool and protected.

Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on / No indicator lights | No AC power; Faulty wall outlet; Damaged power cord. | Check AC power connection. Try a different outlet. Inspect power cord for damage. |
| Battery not charging | Incorrect battery connection (reversed polarity); Poor connection to battery terminals; Battery is severely discharged or faulty. | Ensure correct polarity (+ to +, - to -). Clean battery terminals and ensure secure connection. If battery is severely discharged, it may take longer to initiate charging or may require professional assessment. |
| Charger remains in charge mode for extended periods | Battery capacity is larger than recommended (up to 50Ah recommended, but can charge larger); Battery is deeply discharged or sulfated. | This is normal for larger or deeply discharged batteries. Allow more time. If charging does not progress after a very long time, the battery may be faulty. |
