· Diagnosis of deep-discharge or light sulphation; automatic recovery phase with precisely controlled parameters to recover many neglected batteries, even from as low as 2 Volts. In really difficult cases the interactive programme gives the battery a "Turbo Recovery" charge.
· Multi-stage automatic charging programme monitors and controls both voltage and current while charging the battery to ensure optimum charge for the battery, without any risk of over-charging. OptiMate 4 is totally safe even for long-term connection.
· Automatic double-check ensures that the battery is fully charged before switching over to maintenance (float charge) mode. If the check indicates that the monitored signals suggesting full charge were premature, the charger reverts to the main charging stage and continues this procedure until the battery is definitely fully charged.
· Hourly checks (in maintenance mode) for any signs that the battery is not able to hold its charge, or that it is being drained by something connected to it. If all is well, the green LED indicates after the first of these hourly checks. With OptiMate 4, five test results can be indicated and are continually updated. This avoids the situation where a one-off power drain (e.g. alarm) causes a red LED indication indefinitely. In this way, OptiMate 4 continues to test & maintain your battery indefinitely, displaying a real-time battery condition test result. Should a power drain or defective battery be detected, the red LED will indicate a "suspect" condition but the charging circuit will continue to support the battery until disconnected.
· Automatic cancellation of charging programme when mains power fails. On restoration of mains power the battery is automatically re-assessed and the charging programme appropriate to the battery status is immediately restarted.
· Now includes IP64 protection against water ingress.
