Saft's VH super high energy and VHT very long life Ni-MH cells are designed for applications that demand fast charge and discharge capability over a prolonged lifetime. 

VH Cs, VH D and VH F cells are designed specifically for high energy density applications requiring fast charge and high discharge rates (50 A) and specially target cordless power tools, e-bikes and personal electric vehicles, radio control and professional electronics equipment.

The VHT series has been engineered for very long life (1000 - 2000 cycles) in extreme range of temperature conditions and targets back-up, medical and small off-grid photovoltaic applications.

Main applications

  • personal mobility (electric and assisted bikes, scooters, golf caddies, electric wheelchairs, assisted systems for disabled persons, …)
  • professional tooling (construction tools, agricultural tools, vacuum cleaners, …)
  • medical equipment (homecare ventilators, respirators, cardiac defibrillators, medical carts, electric wheelchairs, …)
  • personal care (shavers, …)
  • emergency lighting units (exit signs, emergency lighting fixtures, conversion kits)
  • UPS and back-up systems
  • professional lighting (torches & lamps, flashlights,…)
  • radio communication and tracking equipment (portable radio communication, private mobile radio)
  • military equipment
  • professional electronic devices (handheld terminals, video, …)
  • photovoltaic applications
