OptiMate 2 DUO : BRONZE series 12V 2A lead-acid & lithium battery charger & maintainer

The OptiMate 2 DUO (model TM550) fully sealed automatic battery charger delivers 2 Amps of charge to the battery of your modern motorcycle, ATV, car, boat or bakkie. Its fully automatic plug-and-play design and smart DUO technology means all you must do is connect it to your vehicle’s battery and the OptiMate2 DUO automatically adapts to the battery type and size, brings it to full charge and then OptiMate’s proven 24-7 ‘connect & forget’ safe care makes sure your vehicle’s battery remains ready.

DUO : smart battery sensing technology that automatically adapts to any type of 12V lead-acid (Pb) battery, as well as to the 12.8V/13.2V lithium (LFP/LiFePO4) battery in your motorcycle or sports-car. 

EASY : no buttons, no guesswork – just connect and the smart 5-step program does the rest automatically!

SAFE: Smart electronics protects against accidental reverse polarity connection. No sparks if clamps touch as the output stays off until it is connected to a battery with voltage of 4V or higher.

LOW VOLT START: Will charge a battery from as low as 4V. Pulse recovery that is safe for vehicle electronics.

SMART CHARGE: With 2 amps of constant current and ability to automatically reduce to 1 Amp if it senses a smaller battery, this intelligent charger recovers, charges, and maintains your battery 24/7 — ensuring longer battery life, maximum performance, and trouble-free starts.

GREEN TECHNOLOGY: Efficient variable frequency fly-back power conversion reduces power usage and if left connected to AC power, standby power is less than 0.5W. OptiMate saves you money in electricity cost!

More features:

• Charge current - 2 Amps constant current, automatic adjustment down to 1 Amp if small battery is sensed.
• Universal 12V lead-acid Battery Compatibility – Works with STD / flooded / wet-cell with removable filler caps (for adding distilled water) and sealed/maintenance free EFB (Enhanced Flooded Battery) & AGM (Absorbent Glass Mat).
• Lithium LFP/LiFePO4 12.8V/13.2V** Battery Compatibility – Automatically adapts DUO charging algorithm if Lithium LFP battery is sensed, including low voltage recovery and Lithium friendly 24-7 maintenance. Lithium batteries don't need continuous maintenance charging, OptiMate 2 DUO monitors the battery hourly and if it needs charge (below 70%) it brings it back up to 90% for extended life. (Lithium battery capacity and life reduces if kept at 100% when not used). ** nominal voltage is 12.8V (4 x 3.2V), but some battery brands claim 13.2V (4 x 3.3V).
• Safe for Sensitive Electronics – No overcharging, spark-suppressed and short-circuit protected.
• Global input (100–240 V, 50 -60Hz) - connect with Type-C European 2-pin plug
• Eco-Friendly & Weatherproof – For indoor or outdoor use, even in extreme cold (–40°C) or heat (40°C).
• Plug & Play – Includes a set of battery clamps for quick connect and a fused battery lead with M6-8 dual size ringlets that can be permanently fitted to the battery.
• Connect & Forget - Fully automatic time limited charging followed by 24-7 smart adaptable OptiMate DUO (Pb / LFP) maintenance.
