Ultra-compact 20A 12V smart battery charger for RV, marine, work truck, coach, and specialty vehicle applications. Supports flooded, gel, AGM, and lithium-ion batteries with automatic 3-stage charging, universal AC input, and up to three full-current rated outputs.
The Xantrex 804-1220-10 TRUEcharge3 is a 20 amp, 12 volt smart battery charger designed for RV, marine, commercial vehicle, and specialty vehicle battery systems. Its microprocessor-controlled multistage charging helps deliver efficient, reliable charging for compatible lead-acid and lithium-ion battery banks.
The TRUEcharge3 accepts universal AC input from 90–265VAC, 47–63Hz, making it useful for shore power, generator power, and worldwide power environments. It can charge up to three battery banks at the same time, provided the connected batteries are the same chemistry, voltage, and amperage configuration.

The TRUEcharge3 20A charger is well-suited for recreational vehicles, marine systems, heavy-duty trucks, coaches, buses, work trucks, and specialty vehicles that need reliable 12V battery charging from shore power or generator power. This 20A model is best for smaller to moderate 12V battery banks where a compact, multi-chemistry charger is preferred.
• One Xantrex 804-1220-10 TRUEcharge3 20A 12V battery charger • Integrated charger display/interface • Hardwire-style charger connections
The optional Xantrex 808-8040-10 TRUEcharge3 Remote Panel can be used for remote monitoring and control. Xantrex notes that the remote panel is required for TRUEcharge3 parallel stacking, allowing two chargers to combine output current for larger battery banks. Verify accessory compatibility and installation requirements before adding remote monitoring or parallel charging.
When charging multiple battery banks, the connected batteries must be compatible with the selected charge profile. Xantrex notes that batteries should be the same chemistry, voltage, and amperage configuration for safe and effective multi-bank charging. Confirm battery chemistry, bank size, AC wiring, DC wiring, fuse/circuit protection, and charger settings before installation.
