Performance for UPS, telecommunications and emergency power

The M12V155FT delivers stable performance for critical infrastructure such as UPS systems, telecom nodes, power distribution networks as well as security and emergency power systems. The high power density and low internal resistance ensure reliable supply even under peak loads and extended bridging times.

Efficient in operation with minimal maintenance

Absorbent glass mat separators enable short charging times, high energy density and uniform power output. The internal gas recombination of 99 percent means the battery is very low-maintenance. Central degassing increases operational safety in closed rack environments.

AGM front terminal technology for maximum longevity

The lead-calcium grid plates provide high corrosion resistance and a very long service life. The large temperature range from minus 40 to plus 55 degrees Celsius allows flexible deployment locations. Front terminals simplify service work, reduce downtime and minimise installation effort in module cabinets.
