Saft's new VH F nickel-metal hydride (Ni-MH) cylindrical cell has been developed specifically for applications requiring high-energy rechargeable batteries for use in frequent cycling conditions.
The VH F, which Saft believes to offer superior performance compared with any equivalent sized Ni-MH cells currently available on the market, was designed originally to fit electric bicycles and hybrid vehicles and is also ideal for gardening equipment, military electronics and professional video cameras.
The VH F cell combines super high capacity and quick and fast charge capability with an extended cycle life and improved storage ability.
It features a foam positive electrode, a nickel metal-hydride negative electrode and an alkaline electrolyte.
The nominal voltage of the VH F is 1.2V and its typical capacity at C/5 is 13500mAh.
It can provide a continuous peak current of 40A at +20C as well as pulse currents up to 100A.
A standard charge for the VH F is 1350mA for 15h, but it will also quick charge in 5-6h at 3000-2500mA, and can be fast charged in 3-4h at 5000-4000mA.
The VH F is available as an individual cell or can be supplied in a range of standard or custom designed battery packs, complete with electronic monitoring systems.
Saft's VH range of Ni-MH cells also includes AAA, AA, Cs and D HP sizes.
