Item #M5070A
The OnSite Defibrillator uses a disposable, lithium manganese dioxide long-life battery with a five-year shelf life plus a (typical) four-year installed life.
A spare battery should be stored with the defibrillator. Additional batteries should be purchased for defibrillators used frequently for training and/or demonstrations.
The Long Life Philips AED battery uses the same technology used with confidence in millions of cameras.
