Xantrex TRUECharge2 40 Amp marine battery chargers lead the industry with a small footprint and ultra-compact design. In addition to meeting global safety and regulatory standards this battery charger features low electrical interference, and efficient power factor corrected multistage charging. Thanks to their inherent drip-proof design characteristics this charger can be mounted in multiple positions

Designed for recreational and commercial applications worldwide, TRUECharge2 accepts 90 - 265 Vac, 47-63 Hz which makes traveling abroad and handling poor-quality power a breeze. The easy-to-read display of the TRUECharge2 40 A model can be augmented with an optional remote panel. This charger comes with built-in protection against surges and spikes on the AC power line.

This charger features Power Factor Corrected (PFC) Charging, which requires less shorepower for charging batteries. This features frees up more usable AC power for running electrical devices and appliances and reducing the likelihood of tripping shorepower breakers

Three-Stage 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 70-80% of the battery’s state-of-charge at the fastest possible rate.
  • Absorption: Replenishes the remaining 20-30% of charge, bringing the battery to a full charge at a slow, safe rate.
  • Float: Voltage is reduced and held constant in order to prevent damage and maintain batteries at a full charge.

Typical applicatons:


Recreational vehicles

Marine communications sites

Battery back-up systems


  • TRUECharge2 40 A are equipped with PARALLEL STACKING feature. This allows two chargers to work together to combine the output current, achieving up to 80 A for large battery banks. This requires the optional Remote Panel (part #808-8040-01 sold separately).
  • Microprocessor-controlled, multistage charging algorithms
  • Settings for two and three-stage charging
  • Settings for flooded, gel, AGM or lead-calcium batteries
  • Battery-equalization feature
  • Ability to charge batteries drained to extremely low voltage
  • Optional battery temperature sensor (Part #808-0232-01)
  • Protections: Reverse battery polarity protection, Drip-proof design, Over and Under temperature protection, DC over-voltage protection
  • Two Year Warranty


Operating DC Loads: When the battery charger is operating, DC loads such as fans and lights may vary in speed or intensity. This is normal. The Truecharge2 Battery Charger will not harm any load connected to it as long as the load can withstand the maximum voltage of 16.0 V.
