5. PREVENTIVE MAINTENANCE
5.1 INSPECTION
î Examine the outside appearance of the battery. The tops of the batteries and terminal 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 4.5, Torque Values.
5.2 CLEANING
Check the battery for cleanliness at regular intervals and keep terminals and connectors free of corrosion.
Terminal corrosion may adversely affect the performance of the battery and present a safety hazard.
î Disconnect the battery from the charging source and the load.
î Clean the top of the battery, terminals, and connections with a damp cloth or non-metallic brush.
If the battery is extremely soiled, a household cleaner may be used.
î Dry with a clean cloth.
î Keep the area around batteries clean and dry.
6. CHARGING
6.1. BACKGROUND
Trillium batteries are frequently used in applications where lead-acid batteries have previously been utilized. Most
deep-cycle battery chargers will charge the batteries, but many will shut off prior to the battery reaching 100% SOC.
In order to facilitate ease of use and ensure safe operation, the batteries are designed to protect themselves from
overcharging by interrupting the charging current when certain conditions are met. Although this allows a wide variety
of lead-acid charging profiles to be used with varying degrees of success, many charge algorithms will result in
repetitive charge interruption and cycling. This charge cycling is not harmful to the batteries, but users may prefer to
identify a more compatible profile to eliminate or minimize this cycling behavior.
6.2. INITIAL CHARGING
Depending on shipping times and the time since manufacture, your batteries may be received at a partial
state-of-charge. Batteries should be given a full charge prior to first use.
6.3. BALANCING
One function of the electronic Battery Management System (BMS) in Trillium batteries is to maintain balance between
each group of cells within the battery. This allows the battery to deliver full capacity without any cells experiencing an
over- or under-voltage condition.
