OptiMate 2 DUO Battery Charger for AGM, GEL, EFB, Lead-Acid, and Lithium LiFePO4 12V Batteries

The OptiMate 2 DUO battery charger is designed for 12V AGM, GEL, EFB, lead-acid, and LiFePO4 lithium batteries. It automatically charges, diagnoses, and maintains the battery’s charge to preserve its performance, whether the vehicle is used regularly or remains stationary for long periods.
Thanks to its DUO technology, the battery charger automatically detects the type of battery connected and applies the most appropriate charging program without requiring manual selection. Its fully automatic five-stage charging cycle optimizes charging, monitors the battery’s condition, and then switches to trickle charging once the battery is fully charged.
With a 2 A charging current, the OptiMate 2 DUO is suitable for motorcycles, scooters, ATVs, SSVs, jet skis, and other vehicles equipped with batteries ranging from 6 to 96 Ah. It can also recharge deeply discharged batteries starting at 4 V, while alerting the user when a battery is beyond repair or defective.
Designed for unattended use, this charger effectively protects the battery and the vehicle’s electronics thanks to its built-in safeguards against reverse polarity, short circuits, and overcharging. Its weather-resistant housing allows for use in both garages and workshops.
Supplied with a permanent wiring harness featuring eyelet terminals and a set of battery pliers, the OptiMate 2 DUO can be quickly installed on most compatible vehicles. Once connected, it automatically provides trickle charging to ensure the battery is always ready to start the engine, while helping to extend its service life.
