High temperature accumulators

NI – Cd Nickel Cadmium. Rechargeable

High temperature accumulators

This technology is specially designed for applications that work in high temperature and permanent load where it is necessary to guarantee a life of 4 years at a temperature of 40º C.

Series VT, VST and VNT

Over time, the VT series has evolved to the VNT series, providing greater energy density thanks to the incorporation of plasticized nickel electrodes, improving its behavior at high temperatures, up to 55ºC in the case of the VNT U series.

Main applications
