10 MSI-4260 Port-A-Weigh Operator’s Manual
1.9 Battery Pack
The
MSI-4260
is powered by a 12 volt Sealed Lead Acid rechargeable battery.
The battery will operate for up to 100 hours (depending on LED brightness setting)
before requiring recharging.
In order to conserve battery life, the scale includes an Automatic Power Off Mode
which senses operational status for no activity after 15, 30, 45, or 60 minutes, and
turns the scale off.
An additional battery saving feature is the Automatic Sleep Mode. This feature
preserves battery life by dimming the display after 5, 15, or 30 minutes of no scale
activity.
Charging time for a completely discharged battery is up to 8 hours. A spare battery
pack is recommended to keep the
MSI-4260
in continuous operation.
Note
To obtain maximum service life from your batteries they should be stored
between -4°F and 122°F (-20°C and +50°C). Stored batteries should be
recharged every three months. Battery is fully charged when the status
indicator is flashing.
1.9.1 Battery Life
The
MSI-4260
battery life depends on a number of factors:
• Brightness of the LED Display and number of segments lit.
• Amount of RF activity, and the age.
• Condition of the SLA (sealed lead acid) battery.
The
MSI-4260
will automatically turn the scale off when the SLA battery drops to
approximately 10.5V. You must recharge the battery when this happens.
Note
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
recharging. 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-4260
electronics,
do not store the MSI-4260 with the battery inside
. Remove the battery
if it will not be used for more than 2 weeks.
1.9.2 Battery Use Guidelines
• Recharge whenever convenient. Do not wait for the scale to shut itself off if your
work situation permits.
• 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.
• SLA Batteries that have not been deep discharged should withstand 500 to 1500
charging cycles.
• The low battery warning will indicate about 2-4 hours of additional use before
the
MSI-4260
turns itself off.
• If the
MSI-4260
is not going to used again soon, remove the SLA battery to
prevent deep discharge while the unit is in storage.
• Recycle the battery to an authorized recycling center when average life drops to
20 hours or less.
