4.9 ON/OFF PUSHBUTTON INDICATOR LED LIGHT
The Trojan
®
OnePack Lithium-Ion battery features a ON/OFF Power Switch with a green ring LED indicator. Below are the
following steps to understand your battery's ON/OFF Power Switch functions:
LED BLINK PATTERN STATUS DEFINITION LED BLINK PERIODICITY
1 short green LED blink Battery Active Indicates the battery is 'active' Repeats once every 4 sec
1 long green LED blink Battery Fault Indicates the battery has a 'fault' Repeats once every 3 sec
2 short green LED blinks CAN Communication Indicates the CAN communication is active Repeats once every 1 sec
NO LED blinks Battery Asleep Indicates the battery is in storage mode NA
4.10 CAN BUS
The battery includes a Controller Area Network (CAN) bus communications interface. The two circular M8
DIN connectors are on the side of the battery to enable communication with the battery and support battery
accessories such as the Dashboard SOC Gauge Kit (10001373). For normal battery operation, the CAN bus
feature is not required. The battery operates and protects autonomously; it does not require any CAN bus
communication or external devices such as external controllers. Keep the two black caps installed on the two
M8 connectors to protect them from the environment when not used. Trojan’s field service can retrieve the
battery usage history and view status over the CAN bus interface to help resolve issues or questions. A certified
field service technician can update the battery firmware over the CAN bus as needed. The CAN bus interface is
galvanically isolated from the internal battery voltages. Therefore, an external power source is required to turn on
and power the field side of the isolated CAN bus. Contact Trojan’s technical support engineers if you have any
questions about the CAN bus interface and its use.
See Section 8: “Maximizing the Performance of Your Battery” for technical support information.

connections should be clean, dry and free of corrosion.
î Check battery cables and connections. Replace any damaged cables and tighten any loose
connections.
Refer to Section 4.2: “Terminals and Torque Values.”
î Verify mounting brackets are still securely mounted to both the battery and the vehicle.
