CNFJ Stationary Range

The CNFJ range of Lead Crystal® batteries can be used for applications where power is necessary only on a UPS standby or emergency basis referred to as Reserve Power.

Where the EVFJ range of batteries is designed for quick deep discharge the CNFJ battery is the complete opposite as energy storage batteries for UPS are infrequently discharged and often remain on a continuous float charge so are ‘ready and waiting’ for immediate use if the mains power fails.

A growing practice, particularly within the datacentre sector is to draw down the energy stored in the UPS batteries during times of peak power demand and recharge them at night when demand on the electricity grid is less and therefore cheaper.

The CNFJ is ideal as a UPS battery for these applications, form-fit-function designed to replace the standard VRLA battery or GEL battery where extreme temperatures are present and greater longer lasting performance is demanded.

Traditionally, batteries have a 5 year design life in temperatures between 0°C and 20°C but when situated in higher or colder temperatures then the life of standard storage batteries is greatly reduced, but our CNFJ battery lasts 6 x longer at 40°C which is 7½ years versus 1¼ years for a standard battery.

This technology of battery is commonly used for UPS & critical lighting applications providing emergency backup power and also used in DC systems including telecommunications equipment.

The Lead Crystal® battery stores electrical energy for times of peak power demand.
