Cellyte TRA series (OPzS / Flooded)

Cellyte TRA series (OPzS / Flooded)

The SEC Cellyte TRA series of OPzS flooded tubular single cells is a traditional design that complies with International DIN standards. The range is engineered with die cast tubular grids and optimised pasted negative plates to produce an excellent float life, outstanding cycling capability and a very high operational reliability. Meanwhile, the combination of low antimony alloys and a large electrolyte reserve keeps maintenance to a minimum. The resulting range is perfect for high integrity critical applications including power generation & distribution, telecom and premium renewable energy projects.

The 2V series is available in a wide range of capacities from 100 to 3000 Ah in clear SAN cases.

The TRA range is manufactured in SEC’s ISO approved factories and is backed by a full 5 year warranty as standard.
