5.3.1 Storage guidelines for the Li-Ion
battery
Never store Li-Ion -version MultiPro
instruments at temperatures above 30
degrees Celsius (86 degrees Fahrenheit). Li-
Ion batteries may suffer deterioration
resulting in damage to the internal
components when stored at high
temperatures. The battery may be
irretrievably damaged resulting in reduced
battery capacity and voltage.
Biosystems recommends leaving MultiPro
instruments with Li-Ion rechargeable
batteries on the charger when not in use.
5.3.2 Charging guidelines for Li-Ion
battery
The Li-Ion battery in the MultiPro should
never be charged at temperatures lower than
5 degrees Celsius (40 degrees Fahrenheit)
or higher than 30 degrees Celsius (86
degrees Fahrenheit. Charging at
temperature extremes can permanently
damage the MultiPro Li-Ion battery.
The MultiPro must be
located in a non-hazardous location
during the charging cycle. Charging the
MultiPro in a hazardous location may
impair intrinsic safety.
5.3.3 Charging procedure for Li-Ion
battery
Do not charge the
MultiPro with any charger other than the
appropriate Biosystems MultiPro charger.
Standard versions of the MultiPro must be
charged with the UL/CSA-approved
charger, which is Biosystems part
number 54-49-103-1. European versions
of the MultiPro must be charged with the
ATEX-approved charger, which is
Biosystems part number 54-49-103-5.
1. Verify that the instrument is turned off. (If
it is not, press the MODE button for three
seconds until the message "Release
Button" appears.)
2. Plug the power supply in. The red LED is
labeled “Power” and will be lit whenever
the charger is plugged into a power
source.
3. Insert the MultiPro into the charging
cradle bottom side down with the display
facing forward. The green LED on the
charger is labeled “Charge” and will be lit
while the battery is charging.
4. When the battery is fully charged, the
“Charge” LED will go out.
See section 5.3.4 for battery
troubleshooting guidelines.
5.3.4 Charging with the pump attached.
To charge the MultiPro battery
with the pump installed on the
instrument, a spacer is used in
the charger base to make up the
difference between the size of the
MultiPro and the size of the
pump, which is slightly smaller.
The spacer should be oriented
with the gap towards the front of
the charger, and with the guide
pins facing down towards the
charger as shown in the
illustration at right.
Once the spacer has been inserted, the
MultiPro with pump may be charged
according to the instruction given in section
5.3.3 above.
5.3.5 Battery
troubleshooting
If the green “Charge” LED on the charger
fails to light when the MultiPro with Li-Ion
battery pack is placed in the charger, remove
the instrument from the charger and press
the MODE button to attempt to start the
instrument.
If the battery has been inserted into the
charger without the instrument, return it to
the instrument prior to attempting the restart.
1. If the MultiPro starts and the battery icon
shows all three bars, then the battery is
fully charged and may be used. In this
case, the charger has recognized that the
battery is charged and will not charge it
any further.
2. If the MultiPro fails to turn on, then the
battery may be severely discharged and
should be returned to the charger. The
charger will then begin a very slow
recharge in order to protect the battery.
The green “Charge” LED may not be lit
during the first four hours of the slow
recharge. If the “Charge” LED has still
not been lit after four hours, the battery
pack or charger is probably damaged.
3. If the MultiPro starts and any battery level
other than full is indicated, then either the
battery is damaged or the charger is
damaged. Call Biosystems for further
instructions.
