Optimate Lithium TM-390 Battery Charger

OptiMate Lithium 4s 6A, the PRO battery charger of the LITHIUM series for 12.8V/13.2V LiFePO4 / LFP batteries in motorcycles, vehicles, and high-performance / competition equipment

General features of the Optimate tm 390 lithium charger - maintainer:

• High-performance charger with diagnostic and tester for LiFePO4/LFP batteries.
• Perfect for charging and maintaining LiFePO4/LFP batteries of 12.8 V-13.2 V between 3 and 72 Ah seasonally.
• Charging amperage: 6A (Ampmatic current)
• Charging volts: Nominal: 12.8V – 13.2V range: 0.5V – 14.4V
• Operation: Completely automatic
• Features: Starts from 0.5V with continuous monitoring/testing of charge acceptance or defective cell/short condition. Prevents unnecessary (and unsafe) charging of a defective battery.
• Usage: Indoors or outdoors (minimum temperature: -40°F / -40°C).
• Power supply: Global power supply (100–240V & 50–60Hz), high performance (CEC rating), fully sealed.
• IP54 protection against splashes. Suitable for use down to -40°C / -40°F.
• Included: Splash-proof battery cable and standard battery clamp set
• Recovery: Low voltage start from 0.5V and low voltage recovery and testing in 3 phases.
• Safety: No risk of overcharging. Totally safe for the vehicle's electronic system. Spark suppression. Safe for long-term battery maintenance. Automatic disconnection when the battery is short-circuited or disconnected.

Special functions:

• Automatic current adjustment to fit the size and state of the battery.
• Recovery from voltage levels as low as 0.5V.
• 24/7 maintainer: Keeps the battery fully charged and in good condition.
• Checks the state of the batteries (S.O.H.)
• Alerts when damage to the battery is detected
• SAVE mode (recovery) for the battery: operates from 0.5 V with continuous monitoring of charge acceptance or cell status (depleted or inadequate). Thus, it prevents unnecessary (and unsafe) charging of a battery in poor condition. It is safe to leave it connected. Total electronic protection.
• safeT°: automatic adjustment of the charging current in the charger based on ambient temperature. Reduced charging at sub-zero temperatures and no charging if the temperature is below -20 °C / -4 °F (may damage lithium batteries).
• Ampmatic: the microprocessor adapts the current to the ideal charging curve of LiFePO4 according to the size and state of the battery to ensure that the charging is as complete and fast as possible.
