Battery Maintenance

11-9

A fully charged M3516A battery, operating at room temperature, provides 
greater than 2.7 hours of monitoring or more than 50, 200-joule charge-shock 
cycles. 

Life-expectancy of a battery depends on the frequency and duration of use. 
When properly maintained and stored, the life-expectancy of a battery is 
about 2 years. For more aggressive use models, life-expectancy may be less.

Batteries should be used regularly and rotated to distribute the use evenly. 
When storing batteries, make sure that the battery terminals do not come in 
contact with metallic objects.    

Batteries should not be stored without charging for more than one month, if 
installed in the defibrillator, or more than three months, if not installed in the 

defibrillator. Storage at temperatures between 15

o

C (59

o

F) and 30

o

C (86

o

F) is 

recommended to maximize life-expectancy. 

Storing at temperatures above 35

o

C (95

o

F) for extended periods of time will 

significantly reduce a battery’s life-expectancy. 

Batteries should be discarded two years after the first Test Date (as written on 
the battery’s back label), or sooner, if there are visual signs of damage or if 
they fail the Battery Capacity Test. Batteries should be discarded in an envi-
ronmentally safe manner. Properly dispose of batteries according to local reg-
ulations.
