Q: Is the green blinking normal on the Tecmate Optimate 3 and when can it be unplugged?

Yes, the green blinking is normal. The Tecmate Optimate 3 produces this blinking during the TEST & MAINTAIN phase (phase 3). This blinking green LED indicates that the charger is testing the battery's ability to hold its charge after full charging. This phase lasts 12 hours . Complete cycle progression: Before reaching this green phase, the battery first goes through a main charge (LED #4 lit) that lasts approximately as long as the battery's capacity in Ah (for example, 10 hours for a 10 Ah battery). Once full charge is reached, the 12-hour test automatically begins during which the current is interrupted to assess whether the battery maintains its voltage. When to unplug: You can unplug after the test phase (once the green blinking is finished). The battery will then be properly charged and tested. If you prefer to leave the charger plugged in, no problem: after the test, the Optimate 3 switches to automatic maintenance mode where LED #5 becomes steady (blinking finished). The charger then alternates between 30-minute floating charge periods and 30-minute rest periods to maintain the battery indefinitely without the risk of overcharging. Unlimited maintenance mode: Unlike the green blinking that lasts 12 hours, the maintenance mode with a steady LED can operate as long as you wish. You can therefore leave your battery connected to the Tecmate Optimate 3 for weeks or months safely. The charger will automatically compensate for the battery's natural self-discharge. Safe disconnection advice: Before unplugging the DC cables from the battery, always disconnect the mains power from the charger first. This avoids any electrical issues when handling the connectors.
