OptiMate PRO-1 Duo Professional 12V Charger

A dual-chemistry shop charger for fast, accurate charging and safe maintenance of 12V lead-acid and LiFePO4 batteries. Ideal for workshops, dealerships, and multi-vehicle enthusiasts who need reliable diagnostics and repeatable results.

What it does

• Dual-chemistry: Select lead-acid (flooded, AGM, GEL) or LiFePO4 mode for correct voltage and end-of-charge behavior.
• Automated diagnostics: Assesses battery state (voltage and charge acceptance) before and during charging to help identify weak or failing batteries.
• Charge and maintain: Brings batteries to full charge, then switches to safe maintenance to prevent overcharge during storage.
• Workshop-ready design: Rugged housing with clear status indicators for quick checks at a glance.

Who should choose it

• Shops and dealerships servicing mixed fleets with both lead-acid and LiFePO4 batteries.
• Enthusiasts maintaining multiple motorcycles, ATVs/UTVs, or seasonal equipment.
• Anyone needing a charger suitable for repeated daily use with clear, actionable diagnostics.

When to consider something else

• You only service one chemistry (e.g., lead-acid only) and want a simpler, lower-cost unit.
• You need a charger for 6V or 24V systems (the PRO-1 Duo is 12V only).
• You require a compact travel maintainer for occasional use rather than a workshop unit.

Quick start

1. Identify battery chemistry and condition. For LiFePO4, confirm it is a 12.8V/13.2V pack intended for powersports.
2. Select the correct charging mode (lead-acid or LiFePO4) on the charger.
3. Connect to the battery: positive to positive, negative to negative. Ensure solid, clean connections.
4. Power the charger and confirm status indicators match the selected chemistry and charging stage.
5. Allow the charger to complete its cycle. For storage, leave connected; the maintenance program will manage top-ups automatically.

Charging time estimates

Rule of thumb: charge time (hours) ≈ (battery Ah ÷ charger output A) × 1.2. Example: An 8–12 Ah motorcycle battery typically reaches 80% in a few hours on a professional charger; severely depleted batteries may require overnight charging. Always verify the charger's output rating and the battery manufacturer’s recommended charge current.

Compatibility

• 12V lead-acid: flooded (wet), AGM, GEL.
• 12.8V/13.2V LiFePO4 powersports batteries, including many with built-in BMS.
• Common applications: motorcycles, scooters, ATVs/UTVs, snowmobiles, personal watercraft, lawn/garden equipment, and similar 12V systems.
• Not for 6V or 24V systems. Not for lithium chemistries other than LiFePO4 (e.g., NMC, LCO) unless explicitly supported.

Maintenance and storage use

• Safe to leave connected for long-term maintenance; the charger monitors and tops up as needed.
• For flooded lead-acid, check electrolyte levels periodically during long-term maintenance.
• Store and use the charger in a dry, ventilated area away from ignition sources.

Alternatives to consider

• Single-chemistry lead-acid charger: If you never service LiFePO4, a dedicated lead-acid model may be simpler.
• Compact maintainer: For travel or a single stored vehicle, a lightweight maintainer may be more convenient.
• High-output shop charger: If you routinely charge large-capacity automotive batteries, consider a higher-amp professional charger rated for that use.

Safety notes

• Select the correct chemistry mode before charging; wrong settings can damage the battery.
• Do not charge LiFePO4 below 32°F (0°C) unless the battery/BMS explicitly allows low-temperature charging.
• Inspect batteries for swelling, cracks, or leaks. Do not charge damaged batteries.
• Ensure good ventilation. Avoid sparks and open flames near charging lead-acid batteries.
• Follow the indicator legend on the charger for status and any fault conditions.

Basic specifications

• Input: 100–240V AC, 50/60 Hz (worldwide mains).
• Output system voltage: 12V.
• Chemistries: Lead-acid (flooded, AGM, GEL) and LiFePO4.
• Maintenance/float mode: Supported.
• Housing: Rugged workshop-grade casing with clear status indicators.

FAQ

Can it recover a deeply discharged battery?

The charger performs automated checks and may attempt gentle recovery if the battery is serviceable. Severely sulfated lead-acid or LiFePO4 packs with tripped or damaged BMS may not recover. When in doubt, test the battery after charging and replace if it fails a load test.

Is it safe to leave connected all winter?

Yes. The maintenance program monitors state-of-charge and tops up as needed, which is suitable for seasonal storage.

Does it work with batteries that have a built-in BMS?

Most 12V LiFePO4 powersports batteries with a BMS are compatible. If the BMS has low-temperature or over-discharge protection, follow the battery maker’s instructions for waking or charging.

Can I use it as a power supply for ECU flashing?

No. It is a charger/maintainer, not a stabilized power supply. Use a dedicated power supply if a fixed voltage source is required.

What do the indicator lights mean?

Refer to the front-panel legend. Indicators typically show testing, bulk/absorption charging, and maintenance stages, plus fault conditions such as reverse polarity.
