This Petzl Zoom Round Cell Adaptor E13 is designed for use with the Petzl Zoom Head Lamp. Ordinarily, the Petzl Zoom requires flat 4.5-volt batteries to function. This Round Cell Adapter offers an alternative of using three standard AA batteries instead. This is advantageous when batteries need replacing as the majority of battery-operated household appliances ask for AA batteries so you’re much more likely to have them lying around the house rather than having to seek out a flat 4.5-volt battery.

The Round Cell Adapter is simple to fit, slotting snugly into the usual battery compartment of the Zoom head lamp.
