Charging guideline
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.
Use the Cadex SMart Two+ charger to charge the battery instead of
charging the battery inside the patient monitor.
The Cadex SMart Two+ charger maintains a lower battery cell
temperature during the charge cycle than the patient monitor. This
reduction in temperature will extend the life of the battery.
The Cadex SMart Two+ charger charges one battery in less than 4
hours and two batteries in less than 8 hours. When two batteries are
used, the charger applies half of the charging current to each battery.
Conditioning guideline
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.
Remove the battery from the patient monitor every six months and
condition it using the Cadex SMart Two+ charger. This condition cycle
recalibrates the electronic fuel gauge.
Storage guidelines
Do not purchase more batteries than you will use in one year. The
battery does not have an indefinite shelf-life. See “How to store the
battery” on page 5-12.
How to identify battery charge capacity
Battery capacity definitions
The following terms are used to define the capacity of the battery:
Design Capacity — The theoretical capacity of the battery cells when
the battery is new.
Full Charge Capacity — The actual amount of charge the battery can
store and deliver to the patient monitor.
Remaining Charge Capacity — The amount of Full Charge Capacity
currently remaining in the battery. This is a percent of Full Charge
Capacity.
Identify battery charge capacity using the patient monitor
that has 100% Design Capacity and is charged to of this capacity
approximately Full Charge Capacity declines, the approximate run time
of a fully charged battery will decrease.
