Xantrex TRUEcharge3 20A 3-Bank Battery Charger for 12V Lithium, AGM, Gel, and Flooded Batteries

TRUEcharge3 20A 3 Bank Battery Charger - 12V

TRUEcharge3 battery chargers lead the industry with a small footprint and ultra-compact design. In addition to meeting global safety and regulatory standards, they feature low electrical interference and efficient power factor-corrected multistage charging. The TRUEcharge3 Chargers can be mounted in multiple positions thanks to their inherent drip-proof design characteristics. Unlike its predecessors, TRUEcharge3 is lithium-ion battery compatible.

Designed for recreational and commercial applications worldwide, TRUEcharge3 accepts 90265 Vac, and 4763 Hz, which makes traveling abroad and handling poor-quality power a breeze. The easy-to-read display of the TRUEcharge3 12 V models can be enhanced with an optional remote panel. Each model has built-in protection against surges and spikes on the AC power line.

Features:

• Microprocessor-controlled, multistage charging algorithms
• Settings for two and three-stage charging
• Battery-equalization feature
• Settings for flooded, gel, AGM, or lithium-ion batteries
• Equipped with parallel stacking (remote panel required)
• Ability to charge batteries drained to extremely low voltage
• Added quiet mode

Protection Features:

• Reverse-battery polarity protection
• Drip-proof design
• DC over-voltage protection
• Over-temperature protection
• Circuit breaker protection

Three-Stage Charging

Multistage charging ensures batteries receive optimum charging, but with minimal wear and tear, regulating the voltage and current delivered to the batteries in three automatic stages:

• Bulk: Replaces 7080% of the batterys state-of-charge at the fastest possible rate
• Absorption: Replenishes the remaining 2030% of charge, bringing the battery to a full charge at a slow, safe rate
• Float: Voltage is reduced and held constant to prevent damage and maintain batteries at a full charge for the remaining 2030% of charge, bringing the battery to a full charge at a slow, safe rate

Power Factor Corrected (PFC) Charging

Less shore power is required for charging batteries, freeing up more usable AC power for running electrical devices and appliances and reducing the likelihood of tripping shore power breakers.
