Key Features

• Microprocessor-controlled, multistage charging algorithms for precise battery management
• Supports two and three-stage charging settings to extend battery life
• Battery-equalization feature to maintain balanced charge across all batteries
• Compatible with flooded, gel, AGM, and lithium-ion batteries, including LiFePO4
• Parallel stacking capability (remote panel required) for expanding charging capacity
• Ability to charge deeply drained batteries, bringing them back to full capacity
• Added quiet mode for minimal operational noise onboard

Enhanced Protection Features

• Reverse-battery polarity protection to prevent damage from incorrect connections
• Drip-proof design ensures reliable performance in harsh marine conditions
• DC over-voltage protection safeguards your batteries from excess voltage
• Over-temperature protection maintains optimal operating temperatures
• Circuit breaker protection adds an extra layer of safety against electrical faults

Three-Stage Charging for Optimal Battery Health

Experience the benefits of multistage charging, which delivers the right amount of voltage and current to your batteries through three automatic stages, minimizing wear and tear while maximizing battery lifespan:

1. Bulk: Quickly restores 70–80% of the battery’s state of charge at the fastest possible rate.
2. Absorption: Replenishes the remaining 20–30% of charge, bringing the battery to full charge safely and efficiently.
3. Float: Reduces and maintains the voltage to prevent overcharging, ensuring batteries remain fully charged without damage.

Power Factor Corrected (PFC) Charging

The TRUEcharge™3’s Power Factor Corrected (PFC) technology optimizes the use of shore power, allowing more AC power to be available for running your boat’s electrical devices and appliances. This reduces the likelihood of tripping shore power breakers and enhances overall power management onboard.
