Disqualified Batteries

The XC Series can identify when a battery will not accept a charge (battery is

damaged) or when it is fully charged (healthy) and does not require further charge.

Batteries that will not accept a charge will be removed (disqualified) from the

charging sequence until all banks are checked again (every 15 minutes). A damaged

battery will continue to be disqualified each cycle and the charger will not waste

energy trying to charge it. Under some conditions it is also possible that a healthy

battery that is fully charged but unable to accept current (for example, at the

moment it transitions from Absorption to Float or Rest) will be deemed unable to be

charged and temprarily removed from the charging sequence. The charger will enter

an adaptive float/no float behaviour where it will alternate between float charging

(

) and resting the battery ( ) and the 25% Charge Current indicator light on

the onboard status panel will flash. The battery will be evaluated every 15 minutes

and added back to the charging sequence when it is later able to accept charge.

If disqualification occurs during Bulk or Absorption, the battery is damaged or

there is another charging source present other than the charger itself. The remote

display will show and the 25% Charge Current indicator light on the onboard

status panel will flash.

Measuring Battery Voltage

Use a voltmeter that has a stated accuracy of 0.5% or better on DC voltage. Place

the probes of the meter directly on the studs or plates of the charger terminals. Do

not probe on the wire lugs or other places in the battery wiring system as this will

introduce error into the measurement: the charger monitors battery voltage as

measured at the charger terminals.

Temperature Considerations

Xantrex strongly recommends that you install a Battery Temperature Sensor (BTS)

to protect your battery and improve charging accuracy. It is best to use a separate

BTS with each individual battery bank, to provide optimal charging and protection

of each bank. If no BTS is connected, the charger defaults to the charging

conditions for 40 °C (104 °F). At this temperature the charging voltage is lower to

keep batteries from overcharging; charging will be slower and the batteries will be

slightly undercharged.
