6) Remove the battery by pulling straight back.
7) Install a fully charged battery by plugging it in to the exposed battery jacks. The crane scale will turn on
briefly then turn itself off.
8) Reattach the battery retaining strap.
9) Reseat the access panel.
10) Put pressure on the plate to partly compress the gasket. While applying pressure, turn the cam-latch knobs
clockwise until the plate is reseated. Make sure the plate is firmly in place.
BATTERY LIFE
The MSI-9300 battery life depends on a number of factors: Brightness of the LED and number of segments lit,
the amount of RF activity, and the age and condition of the SLA (sealed lead acid) battery. The MSI-9300 will
automatically turn the scale off when the SLA battery drops to approximately 10.5V. You must recharge the
battery when this happens. Leaving a discharged battery in the scale, which has a maintenance battery drain,
can result in a deep discharged battery which will shorten its service life.
SLA batteries do not suffer from memory effects and actually benefit from frequent rechargings. Recharge
the battery whenever it is convenient even when it still has available life. Due to the maintenance discharge
imposed on the battery by the MSI-9300 electronics, do not store the MSI-9300 more than 7 days with the
battery inside. Remove the battery.
Battery Use Guidelines
1) Recharge whenever convenient. Do not wait for the scale to shut itself off if your work situation permits.
2) If you need the scale continuously, keep a fully charged spare battery. Replace the drained battery as close
as possible to the low battery warning, or earlier.
3) SLA Batteries that have not been deep discharged should withstand 500 to 1500 charging cycles.
4) The low battery warning will indicate about 2-4 hours of additional use before the MSI-9300 turns itself
off.
5) If the MSI-9300 is not going to used again soon, remove the SLA battery to prevent deep discharge while
the unit is in storage.
BATTERY CHARGER
Each MSI-9300 Series crane scale is shipped with a battery charger (MSI P/N 502221-0001) designed to
charge and maintain the battery. Exact charging time will depend on the degree of discharge of the battery. A
battery removed when the low battery warning first appears should take about 4-6 hours to fully charge. A deep
discharged battery might take 24 hours to recover.
Using the Charger
1) Remove the Battery from the 9300. See previous page for removal instructions.
2) Connect the charger assembly to the AC supply (86-260VAC). The Power Status light should be green. If
the power status light fails to illuminate, check your AC power connection and make sure the VAC jack is
fully seated.
3) Plug in the polarized connector to the jacks on the battery.
4) The Charge Status light should turn ORANGE indicating fast charge.
If the status light remains Green when the battery is first plugged in, the battery may be defective.
5) Charge until the status light turns GREEN.
Deep discharged batteries may require a couple days to recover full charge.
When the charge cycle is complete you can (and should) leave the battery on the charger until it is needed. The
charger keeps a maintenance float charge on the battery to ensure the best possible operation times. For scales
that are in high usage, MSI recommends obtaining a spare battery so one can always be on the charger.
