Datasheet

Engineered for cycling applications
Saft's VRE 1/2 D cell ideally suits
for a wide range of applications.
In addition, the VRE 1/2 D
is well-adapted for applications
requiring a permanent charge
(C/20) at temperatures of up to
+ 35°C.
To meet customers’ requirements,
Saft provides custom-designed
and standardized battery packs.
