Introduction

The OptiMate 1 Duo is one of the most user-friendly and versatile battery maintainers in the OptiMate range. Designed for both lead-acid and lithium (LiFePO₄) batteries, it’s compact, weatherproof, and perfect for motorcycles, scooters, ATVs, small watercraft, and seasonal vehicles. Its dual-chemistry intelligence automatically selects the right charging program, making it effortless for any user while ensuring maximum battery life.

Why Choose the OptiMate 1 Duo?

Unlike traditional trickle chargers, the OptiMate 1 Duo doesn’t just feed your battery a constant current. It diagnoses its condition, delivers the optimal charge, and maintains it at full capacity for as long as it’s connected. This protects against overcharging and sulfation, ensuring your battery is ready whenever you need it.

Dual-Chemistry Advantage

One standout feature is the ability to handle both lead-acid and lithium batteries automatically. This means you can use a single charger for multiple vehicles in your garage, even if they use different battery types.

• Lead-Acid Support: AGM, GEL, and flooded batteries are all covered.
• Lithium Support: LiFePO₄ batteries benefit from precise voltage control and cell balancing.

Automatic Operation

The OptiMate 1 Duo requires no complicated settings. Simply connect it to your battery, plug it into the wall, and let the smart microprocessor do the rest. The charger detects chemistry, assesses charge level, and begins the appropriate program.

Charging Stages

1. Diagnosis: Checks battery voltage and chemistry.
2. Charge: Delivers a safe, regulated current until optimal voltage is reached.
3. Optimization: Fine-tunes voltage and current to balance cells.
4. Maintenance: Keeps battery topped off without overcharging.

Perfect for Storage

If you store your motorcycle, ATV, or boat during the winter, the OptiMate 1 Duo is your best friend. You can leave it connected for months without fear of damaging the battery. The charger will only supply current when the battery voltage drops slightly, keeping it at peak readiness.

Durability and Design

The unit is fully weatherproof, making it safe for use in garages, sheds, or even outdoor setups. Its lightweight and compact body makes it easy to mount on a wall or keep on a workbench.

How to Use the OptiMate 1 Duo for Lithium Batteries

When charging LiFePO₄ batteries, simply connect the supplied lead to the battery terminals, plug in the charger, and let the automatic detection and charging system take over. No settings need to be changed—the charger switches to the correct lithium profile automatically.
