6.5. PREFERRED CHARGING PROFILES
The recommended charging approach is to use an appropriate I-E charging profile with a voltage setting of 14.4 to
14.8 VDC per battery (28.8 to 29.6 V for the U1). Many AGM or GEL charging algorithms that use an I-E profile will
charge a well-balanced bank of Trillium batteries acceptably. Due to the self-protection features of the Trillium line,
other charge profiles may be used with varying degrees of success.
6.6. CHARGING AT COLD TEMPERATURES
Trillium charging currents must be reduced at colder temperatures. Consult the table below for the maximum
allowable charging current at various temperatures.
6.7. CHARGING PROCEDURE
î Verify that the battery is correctly hooked up to the charger with the positive wire on the
red (+)
terminal and the
negative wire on the
black (-)
terminal.
î If the charger has multiple settings, set it to a “bulk charge” mode (constant voltage / constant current) such as
“AGM”.
î If the charger will not run until it detects battery voltage, be sure that Group 24 or Group 27 batteries are turned
on. If the charger provides charge without detecting battery voltage, and the battery is shut off, the battery will
turn on automatically as soon as the charger starts.
î Start charging, following the charger manufacturer’s instructions.
î After the charge has completed, the charger may be shut off and be disconnected, or if it remains in a
“maintenance mode” at less than 14.0 VDC, it can remain connected to the battery indefinitely.
Chargers which charge at lower voltages will not
harm the battery, but will not provide a full charge to
maximum capacity and may affect range and usable
lifespan of the battery. Chargers which charge at higher voltages will not harm
the battery, but may not provide a full charge because the
battery will shut off as soon as the voltage gets too high
and the charger may not continue to charge the battery
once it turns back on.
