1.10 Battery Charging
Each
MSI-8000
is shipped with a charged battery. However, before using the
MSI-8000
, it
is advised to charge the battery until the Green light shows it is fully charged. When the
BT annunciator first appears, you have approximately two hours of continued operation
remaining. When the BT annunciator starts to blink the batteries are nearly completely
drained. For maximum battery life, MSI recommends recharging the battery as soon as
possible after the BT annunciator turns on. It is safe to charge the battery at any point in its
discharge curve.
If the blue LED is on, the charger is in fast charge mode when first applied and puts 80%
of the charge into the battery within two hours. So even without the top-off Green LED
indicator, a useful charge is available with only a two hour delay. This is assuming that the
battery was not deep discharged or the charger detects a fault.
The Charge Connector is waterproof when connected and screwed in. To maintain IP65 /
NEMA4 ratings, use the supplied plug cover when the connector is not plugged in.
Note
T
he AC end of the charger is not waterproof.
1.11 Charger LED Modes
Blue light
- indicates that a charge is in progress. Charging time varies from
one hour to six hours depending on the charge level of the battery when the
charger is first applied. If the charger is attached as soon as the BT
annunciator lights, then charge time will average three hours. It is OK to
remove the battery charger while the blue light is on, but a complete charge
will not be applied.
Green light
- indicates the battery is fully charged. The powered charger can
be left connected to the
MSI-8000
continuously. MSI recommends leaving
the
MSI-8000
on the charger when not in use.
Red light
- indicates a fault. Faults include over temperature, under
temperature (the battery must be warmer than 14°F (-10°C)), a severely
depleted cell or charge time-out. When the charge times out a trickle charge is
applied to the battery. To clear a time-out fault, unplug the charger and then
plug it back in. A severely discharged cell may take days on the charger to
recover.
1.12 Battery Longevity
The Lithium Polymer Single Cell Battery used in the
MSI-8000
has a rated number of
charges of
≥
300 before capacity starts to degrade. The charging life can be greatly
increased by charging the battery more often, and not let it reach the battery cutoff voltage
of 3.0V. The battery voltage can be seen by pressing a Function key programmed as
“Test”, the battery must be replaced by an MSI certified technician.
Important
If the MSI-8000 is not in use, it is recommended that the charger is left
attached to keep a charge. The MSI-8000 uses a small current when
powered off which has the potential to deep discharge the batteries.
Never store the MSI-8000 with a depleted battery. This can cause
permanent damage to the battery and require factory replacement.
Shelf life with a fully charged battery is approximately three months.
