Most deep-cycle battery chargers will charge the battery, but many will shut off prior to the Trillium battery reaching
100% SOC. Chargers which utilize an automatic desulfation or equalization mode are not recommended. Consult the
appropriate data sheet for limits on charging current, particularly at temperatures below 32°F (0°C).
While the battery is being charged, the display indicator on Group 24 and Group 27 batteries will usually be on,
displaying a pattern and color indicating the state of charge
(SEE “INDICATOR LIGHT” FOR A LIST OF
DISPLAY STATES).
To protect against potential damage, if the battery is shut off due to excessive charge current or high voltage, it will
not turn on when a charger is detected.
(SEE “AUTOMATIC SAFETY SHUTDOWNS”).
For batteries connected in series (24V to 48V systems), each of the batteries can be charged individually for best
results or the batteries can be charged with a multi-bank charging system. Bulk 48V chargers may not charge all
series connected batteries and may require individual battery maintenance charging at periodic intervals to fully
charge the set.
STEPS TO CHARGE YOUR BATTERY TO RECOMMENDED CAPACITY:
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) followed
by a “float” mode (constant voltage) 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 charge has completed, the charger may be shut off and disconnected, or if it remains in a “maintenance
mode” at less than 14.6 VDC, it can remain connected to the battery indefinitely.
