Battery Qualification
The Truecharge2 Battery Charger will perform a battery qualification on each application of AC (or DC > 9 V [for
To force a battery detection sequence,
1.Turn off AC and DC.
2.Wait approximately 20 seconds or until all lights on the charger or remote have gone out.
3.Turn on DC.
4.Turn on AC.
The charger will then perform a battery detection.
The Truecharge2 Battery Charger charges all banks at the same time but the bank in most need of charging is the one that receives the most charge. For example, if Bank 1 and Bank 2 are both charged, but Bank 1 has a load and Bank 2 does not, then the charger may rarely charge Bank 2.
Temperature Considerations
Xantrex strongly recommends that you purchase and install the optional Battery Temperature Sensor (BTS) to protect your battery and improve charging accuracy. Attach the BTS to the warmest battery.
If no BTS is connected, the charger defaults to the Battery Temp. selection on the onboard display as well as on the optional remote panel.
