Charging Overview

The Truecharge™ 2 Battery Charger will perform a battery
qualification on each application of AC, to determine if
battery banks are present and healthy.
To force a battery detection sequence,
1. Turn off AC.
2. Wait approximately 20 seconds or until all lights on the
3. Turn on AC.
The Truecharge™ 2 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.
Measuring Battery Voltage at Charger Terminals
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. Battery voltage should be measured when the
battery is resting, i.e., on the second stage of charging.
2–6
charger or remote have gone out.
The charger will then perform a battery detection when
AC is reapplied
