The 1st nickel battery solution for plug and play replacement of lead-acid.

The latest generation of Uptimax nickel battery technology is the perfect fit to replace lead-acid batteries thanks to its 1.39 V/cell single level charge. When a fast recharge is needed, 95% State-Of-Charge (SOC) in 8h can be reached at 1.45 V/cell for minimal downtime and optimal availability. These improvements come in addition to the key existing benefits of the Uptimax Ni-Cd battery range.

Uptimax Ni-Cd battery combines maintenance-free* operation with total reliability for industrial backup power applications, high electrical performance, long operational life of over 20 years and a low TCO (total cost of ownership). 

Vital support to critical systems

Uptimax pocket plate nickel battery is designed to form the heart of Uninterruptible Power Supply and backup power systems that operate in the event of a loss of the main power supply to facilitate the safe shutdown of processes, safeguard computer data and provide bridge to standby power. Typical power backup applications include UPS, substation switchgears, process control systems, emergency lighting, fire alarms and security systems.

Closing the loop on responsible production

Saft operates the only plant in the world that produces nickel-cadmium batteries incorporating metals that have been reclaimed on site from spent batteries, reducing their eco-footprint.  Recycling Ni-Cd batteries is a complex process that involves separating the nickel, cobalt and cadmium from the electrodes, a process perfected by Saft’s plant in Oskarshamn, Sweden – the only one worldwide involved in both the recycling and manufacturing of Ni-Cd batteries and incorporating recycled metals. 

Saft operates a network of over 30 bring back points worldwide that receive spent Ni-Cd batteries produced at Saft factories, as well as those made by its competitors. The bring back point located in northern Europe brings these used batteries back to Oskarshamn, minimizing transportation. Other bring back points work with other fully permitted recycling partners selected by Saft to ensure that the recovery rates mandated imposed by the EU battery directive are met.

Awards 

Saft was awarded a top rating in 2021 by Ecovadis, a Corporate Social Responsibility (CSR) rating organization for sustainable development performance, scoring in the 96th percentile on: environment, labor and human rights, ethics, and sustainable procurement.
