Three-Stage Charging for Optimal Battery Maintenance

The TRUEcharge™3 employs a meticulous three-stage charging process to ensure your marine batteries are maintained efficiently and safely:

1. Bulk: Delivers 70–80% of the battery’s state-of-charge at the fastest possible rate.
2. Absorption: Replenishes the remaining 20–30% of charge, completing the battery charge at a controlled, safe rate.
3. Float: Maintains the battery at full charge by holding a reduced and constant voltage, preventing overcharging and damage.

Power Factor Corrected (PFC) Charging

TRUEcharge™3's PFC technology ensures efficient use of shore power, leaving more AC power available for your boat’s electrical devices and appliances. This reduces the risk of tripping shore power breakers, making it an ideal choice for marine settings where power management is crucial.
