Exceptional range of temperature T° range (discharge)

• 20°C to +60°C
• 40°C to +85°C

Life duration @ 40°C 1 to 5 years

(according manufacturer)

> 10 years Lower TCO Capacity fading during ageing Linear capacity loss No capacity loss Constant capacity during 10-20 years Safety flammable Non flammable safe Transportation constraints Considered as dangerous good Considered as non dangerous good No transportation constraints Battery management

Many electronics and sensors – loss of reliability

No need to follow up each cell Simple and reliable

The back up lighting device is there to support the technicians during

• perations of maintenance (no more

Power coming from the wind turbine)

Reliability and long life are key !
