ZOLL AED Plus Replacement Duracell 123 Lithium Batteries come in a sleeve containing a set of 10 batteries.  Because the ZOLL defibrillators run on batteries alone, it is recommended that you always have a fully charged set of defibrillator batteries available.  These batteries have a 5-year expiration date when the AED Plus is in standby mode, and they have a 10-year shelf life.    

To be indemnified under the Good Samaritan Law, follow manufacturers guidelines.  Use AEDSafetrack Program Management to document that your AED is compliant with local and state laws.
