6 DDU-120 AED Accessories
This chapter describes the components and accessories that can be used with the Defibtech 
DDU-120 AED. Information on obtaining replacement components and accessories is included 
in the “Contacts” section.
6.1 Defibrillation/Monitoring Pads
The DDU-120 AED is used with Defibtech self-adhesive 
defibrillation/monitoring pads for adults or with attenuated 
pediatric pads for infants and children. These pads (also 
known as “electrodes”) serve two functions:
• Allow the unit to read the patient’s electrocardiograph
(ECG) rhythm.
• Deliver defibrillation energy to the patient when
needed.
The Defibtech self-adhesive defibrillation/monitoring pad 
assembly comes in a “leads-out” sealed package that allows 
the device to be stored with pads connected. When the 
DDU-120 AED is used, the operator needs only to remove 
the pad packaging, tear open the package and turn the device 
on to administer care. The AED has a storage area in the 
back of the unit that allows for storage of a single sealed pad 
package.
6.2 Battery Packs
The Defibtech AED uses a lithium battery pack. The battery 
pack contains the main lithium battery cells, an LED status 
indicator, and a 9V lithium battery. Different capacity battery 
packs are available. Refer to the “Battery Packs” section for 
detailed information on the available packs. The battery pack is 
inserted into the battery pack opening on the side of the AED 
and latches into place.
