Thermal data
Storage conditions
• Avoid atmosphere with corrosive gas
• Disconnect batteries before store or delivery
• Avoid storage of discharged batteries
• Store batteries within the specified temperature range in low
humidity conditions. Optimal storage conditions are:
– relative humidity: < 60 %
– temperature: -20… +25 °C for up to 12 months after printed date of manufacture
• A long term storage in open circuit leads to battery self discharge and deactivation of chemical components. It could be required to charge and discharge
the batteries a few times to recover the initial performance.
Installation & commissioning
Activating NiMH batteries
When using rechargeable NiMH 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
If NiMH batteries or individual cells within a battery pack, are driven into deep discharge state they will not recover after charge / discharge cycles. Therefore it is very important that NiMH 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 12 month without recharging the battery packs.
• Shipment, storage of assembled emergency luminaires with battery pack connected to the emergency driver.
• Long periods of mains-interruptions of more than two weeks, once, the emergency system is installed and the battery pack is connected to the emergency driver.
