3. Allow the jump starter to charge until the CHARGE COMPLETE light comes on
(you can monitor the progress by checking the red POWER LEVEL lights – after
all three POWER LEVEL lights are lit the CHARGE COMPLETE light should
come on).
4. Once the CHARGE COMPLETE light comes on, charge another three to six
hours (three hours is acceptable, but to ensure maximum output capability, six
hours is preferred).
Note: The CHARGE COMPLETE LED indicates that the charging process is
complete. It may illuminate for a short period after the charger is unplugged
from the unit due to the surface charge, but this will only occur for a short time,
which is normal. To assess the unit's readiness, monitor the Power Level LED's.
5. If you are not planning to use your jump starter right away, you may leave it
connected to the wall charger. We recommend that the wall charger remain
connected to the jump starter when not in use.

all of the red lights come on, charge the jump starter another 1 to 2 hours to
ensure a complete recharge.

the jump starter. You must frequently monitor the charging process to ensure
the unit is not overcharged.
WARNING: Overcharging the jump starter when using this charging
method can create explosive gasses which could result in property
damage and personal injury. DO NOT OVERCHARGE!
