Abstract
The power source in a portable defibrillator includes a replaceable first power pack and a rechargeable second power pack. The first power pack charges the second power pack. The second power pack supplies most of the energy needed to administer a defibrillation shock. The first power pack may include one or more lithium thionyl chloride batteries. The second power pack may include one or more lithium ion batteries and/or ultracapacitors.
