OptiMate 2 DUO Charging Process

Step 1: Low Voltage Recovery (4V - 13V)

LED Indicator: LED #3 blinks (on-off-on-off) to confirm deep discharge

Lead-acid/AGM Batteries: Pulsed charging prepares the battery to accept a normal charge.

Lithium (LiFePO4) Batteries: Current stays limited to 0.3A for gentle recovery to 8.8V, then increases to 1A with continuous monitoring.

Duration: 15 minutes minimum, 4 hours maximum

Critical Warning for Small Batteries: Motorcycles, lawn tractors, jet-skis, and snowmobiles with batteries left deep-discharged for extended periods may have permanent cell damage. These batteries can overheat during charging. Monitor temperature hourly and watch for bubbling, leaking electrolyte, uneven cell activity, or hissing sounds. DISCONNECT CHARGER IMMEDIATELY if the battery becomes uncomfortably hot or shows any unusual signs.

Step 2: Health Test

The charger assesses battery health to determine if charging can continue. Healthy batteries proceed to Step 3. Faulty batteries cause charging to suspend and LED #2 to blink, indicating the battery needs replacement.

Step 3: Bulk Charge

LED Indicator: LED #3 (yellow)

The charger delivers a constant current of 2A maximum to the battery up to a voltage of 14.2-14.4V.

Step 4: Charge Verification

The charger verifies battery charge level and equalizes all cells using variable current pulses. A safety feature limits total charge time to 48 hours maximum before automatically progressing to Step 5.

Step 5: Battery Test (30-minute cycles)

LED Indicator: LED #4 (green) indicates 24/7 maintenance mode

No charge current flows during voltage monitoring. The initial test after Step 4 determines if the battery can hold its charge—healthy batteries progress to Step 6, while faulty batteries trigger LED #2 blinking. Ongoing tests determine maintenance needs based on battery type, health, and vehicle electrical draw. Charging occurs if voltage drops below 13.3V. Lithium batteries receive occasional charging while AGM/lead-acid batteries typically require hourly maintenance.

Step 6: Extended Battery Maintenance

The OptiMate maintains batteries in good condition for months. Its pulse conditioning technique prevents sulfation, ensures maximum battery performance, and extends usable battery life. Float charging operates at a safe 13.6V voltage limit with up to 2A current available. The system automatically reverts to Step 3 if it detects sudden high charge loss (such as engine starting while the charger remains connected).

Note: Steps 5 and 6 alternate every 30 minutes until you disconnect the battery.
