6. Care & Maintenance
6.1 Maintenance Inspection
• Examine the external condition of the battery. The top of battery and terminal connections should be
clean, dry, and free of corrosion.
• Check battery cables and connections are firmly secure.
• Check the battery state of charge (SOC) regularly. When not in use the Century Lithium Pro battery will
partially self-discharge.
• Depending on the charging profile used, overtime the series and parallel configured batteries may not
be equally charged. To fully balance batteries in either of these configurations, maintenance charge each
battery individually at periodic intervals.
6.2 Cleaning
• Before cleaning, disconnect the battery from the charging source and the load.
• The surface of LFP battery can be cleaned with a soft, dry cloth made of non-electroconductive material.
• Keep the area around batteries clean, dry, and away from any flammable materials.
7. Storage
• Disconnect the battery from all electrical loads and from the charger to eliminate potential parasitic loads
that may discharge the battery.
• Cover the LFP battery terminals with suitable non-electroconductive material (e.g. insulating tape or
plastic caps).
• Observe the minimum and maximum storage temperatures.
• Store in a cool, dry place. There is no specific ventilation requirements for Century Lithium Pro batteries,
however sufficient airflow should be ensured to prevent excessive heat build-up.
• Keep area free from flammable materials.
• Keep out of reach of children and animals.
• Do not store in direct sunlight.
• The battery should be stored at a state of charge of between 40% ~60% of its nominal capacity.
Storing a deep discharged battery can result in permanent damage and reduced run time.
• Allowing the battery to self-discharge to a severely low state of charge may result in the battery not
being able to be recovered.
• Check battery every 4 to 6 months, or more frequently in ambient temperatures exceeding 35°C, to
determine if charging is required.
