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.
• 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
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 24 hours or until the Battery Status
Icon shows 4 solid bars.
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.
CAUTION –
Risk of property damage: Failure to keep the battery charged will cause
permanent damage and result in poor jump starting performance.
IMPORTANT NOTES:
• Recharging the battery after each use will prolong battery life; frequent heavy
discharges between recharges and/or overcharging will reduce battery life.
• Make sure all other unit functions are turned off during recharging, as this can slow the
recharging process.
• 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 high impedance. The manufacturer suggests leaving the unit
charging for a period of 40 hours using the built-in AC charger before use.
Charging/Recharging Using the Built-In 120
Volt AC Charger and AC Extension Cord (not
included)
1. Lift the protective cover of the built-in 120 Volt AC Charger (refer to the “Features
section to locate). Connect an extension cord to the unit. Plug the other end of the
cord into a standard 120-volt AC wall outlet. When the unit is properly connected
to an AC power source, the LCD screen will display the following:
The bars on the Battery Status Icon represent the charge level of the unit’s internal
battery. The bars on the Battery Status Icon will change from empty to solid
(bottom to top) repeatedly to indicate the unit is charging. The backlight will turn on
for 10 seconds (only).
2. Charge for approximately 24 hours or until the Battery Status Icon shows 4 solid bars.
3. When charging is complete, unplug the AC extension cord from the AC outlet and
then disconnect it from the unit.
