Charging Century Lithium Pro Batteries

Century Lithium Pro batteries are transported to retail stores and kept at a  State of Charge of between 40 - 60% of the battery's nominal capacity - and must be fully charged prior to use.

They can be recharged up to 10x faster than traditional lead acid batteries resulting in less down time and quicker deep discharge recovery.

They are designed to accept a higher rate of charge (50A) compared to 30A for most AGM Deep Cycle batteries.
 

Lithium Pro Charging Information

• The battery must be fully charged before first use.
• Century Lithium Pro batteries should only be recharged using a charger or charging system configured for lithium batteries.
• Before attempting to charge a battery with an external battery charger, it is important to be aware of the safety precautions when charging batteries and follow the instructions outlined by the charger manufacturer. 
• Ensure charging voltage does not exceed 14.6V. 14.4V is recommended.
• Ensure the charging current does not exceed the maximum charging current as indicated in the specification sheet. Any inrush current may activate the short circuit protection function and charging may stop.
• Ensure charging is carried out at an ambient temperature within the recommended range of 0°C~45°C.
• Below 0°C or above 45°C may cause irreversible damage (i.e., permanent loss of capacity) to the battery or even a safety risk.
• DO NOT charge the battery for more than 24 hours. Disconnect the LFP battery from the charger when the charger is no longer in use.
• DO NOT use a lead-acid battery charger if it has ‘Equalisation’ and ‘De-sulphation’ mode or function.
• DO NOT leave a lead-acid battery ‘smart’ charger connected to float charge the LFP battery. This type of charger will NOT maintain a proper voltage algorithm and can cause damage to LFP battery.
• Batteries connected in series do not need to be disassembled for individual recharging. However, each individual battery should be fully charged before being connected in series or parallel. Even after the charger is disconnected, the battery may not be ready until the cells are balanced. After charger has been disconnected allow 30 minutes rest time for the battery cells to balance.
• If charging batteries in series, ensure the charging voltage is less than 14.6V times the series number. For example, to charge 2 LFP batteries in series, the charging voltage should be less than 29.2V and the charging current should be as recommended in the specification sheet.
• DO NOT connect more than 2 LFP batteries in parallel. The voltage difference between the 2 LFP batteries must be below 100mV after being fully recharged and before the batteries are connected. The maximum charging current should be the same as single battery connection.
• Some constant voltage chargers that require the detection of battery terminal voltage to start charging may fail to activate the LFP battery from its state of under-voltage protection (Sleep Mode). The low impedance of LFP cells may result in an inrush of current interrupting the charge. If the charger trips out, reset the charger until charging continues normally.
