Introduction

Your Xantrex Truecharge 10 is an advanced battery charger designed specifically for today’s high performance deep-cycle lead-acid batteries. It provides charging performance that simple marine and automotive chargers are unable to provide.

The Truecharge 10 is designed to recharge 12 volt lead-acid batteries with capacities from 25 amp hours to 200 amp hours. If you wish to charge batteries with capacities greater than 200 amp hours, Xantrex’s Truecharge 20 or Truecharge 40 chargers will be better choices.

To get the full benefit of the Truecharge 10’s capabilities, please read and follow the instructions in this manual. This manual covers both the TC10 115 VAC model and the international TC10i 230 VAC model. TC10i input specifications are shown in parentheses. Pay special attention to the Important Safety Instructions in this manual and to the CAUTION and WARNING statements in this manual and on the Truecharge 10.

Truecharge 10 Features

The Truecharge 10 is a true “smart charger” that automatically provides the correct charge cycle for modern sealed (“gel”) or flooded (“wet”) lead-acid batteries.

Microprocessor Controlled Three-Step Charging

Experts and battery manufacturers recommend that lead-acid batteries be charged with a three-step charge cycle to provide a fast, complete charge. The microprocessor in the Truecharge 10 precisely regulates the voltage and current delivered to the battery, accurately charging without risk of overcharging and battery damage.

Proprietary software algorithms compensate for a variety of conditions which “fool” less sophisticated chargers into delivering an improper charge.

Truecharge 10 10-Amp Continuous Rating

The Truecharge 10 will deliver its rated 10 ampere charging current for most of the charging cycle. The charger only reduces the charging current below this continuous rating level when the battery is approaching full charge. Many other chargers only deliver their rated
