If the clamp connections
to the battery's positive
and negative terminals are
reversed (refer to the "Jump
Starter" section) ...
When the unit is charging
or recharging using
the built-in 120 Volt AC
Charger or
the 12 Volt DC Adapter
(refer to the "Charging/
Recharging" section) ...
NOTE: The unit will automatically power off once ALL the functions
and the charging process are turned off.
Viewing Battery Status
The Battery Status Icon and Battery Voltage Indicator indicate the
battery charge level as follows:
• If the battery charge level is at full capacity, four solid bars will display.
• If the battery is partially charged, two or three solid bars will display.
... the backlit LCD screen will
display the Battery Status Icon,
Battery Voltage Indicator, and the
Clamp Icons. The Alarm Icon, the
"+" and "–" signs and the Reverse
Polarity Icons will flash and the unit
will sound a warning continuously
until the clamps are disconnected
from the battery.
... a beep will sound and the
backlight will turn on for 10
seconds (only). The LCD screen
will continue to display the Battery
Status Icon and Battery Voltage
Indicator. The bars on the Battery
Status Icon will change from empty
to solid (bottom to top) repeatedly.
• If the battery is nearly empty, one solid bar will display. The unit should
be charged at this time.
• If the battery is completely empty, four blank bars will display. The
unit MUST be charged at this time or the unit's built-in low voltage
protection will activate. The empty Battery Status Icon will flash for
a short period of time before automatic shut down. The unit will not
operate until the battery is recharged.
Charging/Recharging
Lead-acid batteries require routine maintenance to ensure a full charge
and long battery life. All batteries lose energy from self-discharge over
time and more rapidly at higher temperatures. Therefore, batteries need
periodic charging to replace energy lost through self-discharge. When
the unit is not in frequent use, manufacturer recommends the battery
should be recharged at least every 30 days and after each use.
Important Charging Notes
1. This unit is delivered in a partially charged state – you must fully
charge it before using it for the first time. Initial AC charge should
be for 40 hours or until the Battery Status Icon shows 4 solid bars.
2. Recharging the battery after each use will prolong battery life;
frequent heavy discharges between recharges and/or overcharging
will reduce battery life.
3. The battery can be recharged using the built-in 120 Volt AC Charger
or the 12 Volt DC Adapter.
4. Make sure all other unit functions are turned off during recharging,
as they can slow the recharging process.
CAUTION – To reduce the risk of property damage: Failure to keep
the battery charged will cause permanent damage and result in poor
jump starting performance.
IMPORTANT: If you know the unit is discharged, but the battery icon
displays four solid bars as if the unit is fully charged when connected to
a charging power source, this may be due to the internal battery having
