Activating LiFePO4 batteries

When using rechargeable LiFePO4 batteries for emergency lighting following point are essential in order to achieve the specified design life time of the batteries:

In order to activate new batteries, 2-3 full charging-discharging are needed to make sure batteries achieve their rated capacity. This activating process is defined by running 2-3 full charging (24 hrs) and discharging (1/2/3 hrs) cycles of the batteries. If the first duration test fails, please repeat the test once again after a 24 hour charging period.

Avoidance of excessive cycling

During building installations, in many cases, mains supply is not available on a permanent 24-hour basis which then leads to unwanted, uncontrolled excessive battery cycles. This has a very strong effect on the design life time of the battery. Make sure that in such situations, the battery remains disconnected in the luminaire till the mains power supply is stable on a 24-hour basis.

It is strongly recommended to refer to the datasheets of Tridonic emergency control gears to avoid excessive cycling. At the same time, make sure that this information is handed over to the installation staff / electrician in order to ensure a proper way of installation and commissioning.

Avoidance of deep-discharge conditions

It is very important that LiFePO4 batteries are not left connected for long periods in a discharged state. Following options may lead to a deep discharge situation and must be avoided:

• Storage periods of rechargeable batteries of over 6/15 month without recharging the battery.
• Shipment, storage of assembled emergency luminaires with battery connected to the emergency driver.
• Long periods of mains-interruptions of more than two weeks, once, the emergency system is installed and the battery is connected to the emergency driver.

Avoidance of deep-discharge conditions

It is very important that LiFePO4 batteries are not left connected for long periods in a discharged state. Following options may lead to a deep discharge situation and must be avoided:
