Volt Dc Charging; Viewing Battery Charge Status - Black & Decker JU300CB Instruction Manual

Notes: 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.
Recharging battery after each use will prolong battery life; frequent heavy discharges between recharges and/or overcharging
will reduce battery life. The battery can be recharged using either the AC or DC Charging Adapter (see below).

Note: Make sure all other unit functions are turned OFF during recharging, as this can slow the recharging process.
AC Charging Method
1. Plug the AC plug of the AC Jump Starter into any standard AC wall outlet.
2. Plug the barrel connector attached to the AC/DC adapter into the small barrel receptacle on the jump-starter.
3. After initial charge, recharge this device as necessary for at least 14-16 hours or until the green FULL
indicator lights. Recharge at least once a month when not in use.
4. When charging is complete and the FULL indicator lights, remove the AC/DC charger plug and store in a
safe place.
Note: The unit cannot be overcharged using the AC method. The Jump-Starter also comes with a DC/DC charging adapter for
recharging the unit from a vehicle's 12 volt DC accessory outlet.

12 Volt DC Charging

The DC recharging method will NOT recharge the unit as effectively as recharging from AC. The 12 volt DC
recharging procedure is recommended only when it is necessary, since frequent use of the 12 volt DC recharging
procedure may shorten the battery system's life.
1. Insert the gold-tipped DC/DC charging adapter plug into the vehicles 12 volt DC accessory outlet.
2. Insert the silver-tipped end plug into the 12 volt DC accessory outlet on the front panel of the unit.
3. To check the charge status of the battery during DC charging, disconnect the DC adapter from the accessory
outlet and push the Battery Charge Level pushbutton. Observe the battery charge indicator.
4. When charging is complete, remove the power cord and return it to the storage compartment.
CAUTIONS:
• To reduce the risk of property damage, do not leave the unit unattended while charging using this method.
• To reduce the risk of shortening the life of the battery; do not recharge the unit using the DC method for more
than 4 hours.
Notes: Make sure all functions are turned OFF during recharge as this may slow the recharging process.
Some vehicles require that the ignition be switched to the accessory outlet position in order to power the accessory outlet.
