2.3.5 Battery Charging
To check the level of charge of the battery, press the button on the battery’s keypad.
The battery gauge/indicator(s) illuminate to indicate the level of battery charge (25-100%).
To charge the FreeStyle 5’s internal battery:
§ Connect its AC power supply or DC (auto) power supply into the
unit’s power receptacle located on the right side of the FreeStyle
5 unit, and the other end to its proper AC or DC power outlet.
(See Figure 3.1).
§ The FreeStyle 5 internal battery will completely charge from a fully
depleted state in approximately 3 hours and 15 minutes.
§ While charging a fully discharged battery, initially the 25% LED
will start blinking rapidly for a few minutes, then start to blink at a
slower rate (½ second).
§ The LED will continue to blink until a 25% capacity is reached. The
LED will then turn solid.
§ Each of the four LEDs, 25-100%, will blink as stated above, then
turn solid when they reach their capacity.
§ Once all LEDs illuminate solid, the battery is fully charged and the
LEDs will remain on solid for approximately 1 ½ hours, then all
four LEDs will turn off.
§ If the AC or DC power supply is not connected, the LEDs will turn off within five
seconds.
Depending upon the temperature of the FreeStyle 5 battery, it can take several minutes for the
charging cycle to start after connecting to power. This is a normal condition and is intended for safe
charging.
The lithium ion rechargeable battery that is used in the FreeStyle 5 unit does not need
to be fully depleted before recharging. It is recommended to charge the battery regardless of the
battery’s capacity level after use.
The battery will charge when the unit is off as well as while the unit is running off the AC or DC
power supply.
Lithium batteries may permanently lose capacity when exposed to extremely hot temperatures with
the batteries fully charged or completely depleted. For extended storage, it is recommended that
batteries be charged 25 to 50% and remain within a temperature range of 73
°F (23°C).
