Battery maintenance
How to charge the battery
The battery can be charged by one of two methods:
 Outside of a patient monitor by using the Cadex SMart Two+ 
charger.
 Inside a patient monitor that is connected to an AC power source.
NOTE
To extend the life of the battery, GE recommends that you charge the 
battery using the external Cadex SMart Two+ charger.
NOTE
The Cadex SMart Two+ charger is no longer available for purchase. 
However, if your site has a Cadex SMart Two+ charger, you should 
continue to use it to charge and condition the battery.
Charging the battery with a Cadex SMart Two+ charger
1. Insert the battery into the battery charger. The RUN LED lights.
2. Leave the battery in the battery charger until the READY LED 
lights.
NOTE
If the FAIL LED lights, remove the battery from the battery 
charger and reinsert it. This should correct any battery charger 
time out errors. However, if this does not correct the battery 
charger time out errors, then the battery is defective and should 
be replaced.
Charging the battery inside a patient monitor
NOTE
Non-recommended (incompatible) batteries will not charge in the 
Dash patient monitor.
The battery is charged whenever the patient monitor is connected to an 
AC power source.
When you store the battery inside of a patient monitor that is connected 
to an AC power source (a state known as “floating”), the battery will self-
discharge to less than 90% of its Full Charge Capacity after 
approximately two weeks (depending upon the temperature of the 
battery). At this time, the patient monitor will automatically recharge 
the battery to 100% of its Full Charge Capacity.
