The Xantrex TRUEcharge3 24V 20A 3-Bank Battery Charger delivers professional-grade marine and RV battery charging in an ultra-compact, drip-proof design. This microprocessor-controlled charger features intelligent multistage charging algorithms optimized for flooded, gel, AGM, and lithium-ion batteries, making it ideal for modern recreational and commercial applications.
Advanced Charging Technology:
The TRUEcharge3 utilizes power factor corrected (PFC) charging technology that requires less shore power, freeing up more AC capacity for onboard appliances and reducing the risk of tripping breakers. The intelligent three-stage charging process includes bulk charging (restoring 70-80% capacity at maximum safe rate), absorption (replenishing the final 20-30% at a controlled rate), and float mode (maintaining full charge without overcharging). An equalization feature helps extend battery life by preventing stratification in flooded batteries.
