Xantrex Technologies 804-2420-10 TRUEcharge3 24V 20A 3-Bank Multistage Battery Charger

The Xantrex TRUEcharge3 24V 20A battery charger is a hardwired, 3-bank multistage marine and RV battery charger with a compact, drip-proof design. It uses power factor-corrected, microprocessor-controlled charging and is compatible with lithium-ion batteries as well as flooded, gel, and AGM types.

Key Features:

• Microprocessor-controlled, multistage charging algorithms with settings for two- and three-stage charging
• Battery equalization feature
• Settings for flooded, gel, AGM, or lithium-ion batteries
• Parallel stacking capability (remote panel required)
• Can charge batteries drained to extremely low voltage
• Quiet mode
• Mounts in multiple positions thanks to its drip-proof design
• Easy-to-read display, which can be enhanced with an optional remote panel
• Accepts 90–265 Vac, 47–63 Hz input for use with shore power worldwide

Protection Features:

• Reverse-battery polarity protection
• DC over-voltage protection
• Over-temperature protection
• Circuit breaker protection
• Built-in protection against surges and spikes on the AC power line

Three-Stage Charging:

• Bulk: restores 70–80% of the battery's charge at the fastest possible rate
• Absorption: replenishes the remaining 20–30% at a slower, safer rate to bring the battery to full charge
• Float: reduces and holds voltage constant to maintain a full charge and prevent damage

Power Factor Corrected (PFC) Charging: Less shore power is needed for charging, leaving more usable AC power for appliances and reducing the chance of tripping shore power breakers.
