SAVE THESE INSTRUCTIONS
INTRODUCTION
Congratulations on purchasing your new Stanley®Fatmax®350 Amp Jump
Starter with Compressor. Read this Instruction Manual and follow the
instructions carefully before using this unit.
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 be recharged at least every 30 days.
IMPORTANT: If you know the unit is discharged, but the battery status LEDs
illuminate 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 24-36 hours using
the supplied AC charger before use.
Notes: This unit is delivered in a partially charged state – you must fully charge it upon purchase and 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 the
supplied 120 Volt AC Charger.
Make sure all other unit functions are turned off during recharging, as this can slow the recharging
process.
CAUTION – RISK OF PROPERTY DAMAGE: Failure to keep the battery
charged will cause permanent damage and result in poor jump starting
performance.
WARNING: Never attempt to use the AC and DC charging methods at
the same time.
Charging/recharging using the 120 volt AC charging adapter
• Make sure all of the unit’s functions are turned off.
• Insert the barrel connector of the AC charging adapter into the 12 volt DC
charging port on the back of the unit. Insert the plug end into a (powered)
standard North American 120 volt 60Hz outlet.
• Once the green LED lights or flashes, continue to charge for approximately 1-2
hours. Charge until two red and one green LED Battery Status Indicators light
solid.
• Disconnect the AC charging adapter and depress the battery status button. If all 3
status lights illuminate, the unit is fully charged.
