TESTING A BATTERY
Determining if the battery is good or bad can be done using the Load Tester. When a battery has been left for a long period
without a charge, it can appear to not be able to be recharged. This may not be the case if these steps are followed, it may be
able to be brought back to life.
1. Use the included testing probes to see if there is any life left in the battery. A battery that read 10 volts or more is likely
to be able to be recharged and rejuvenated. If the battery is below 10 volts the likely hood diminishes as the voltage
goes down. A battery reading 0 volts will probably not recharge... but it is worth trying anyhow.
2. If the battery needs to be charged attach the

to the vehicle using one of
the three methods listed above.
3. Plug in the

to an AC outlet to do its work. The longer the better... this
can take as little as a few hours to as much as a week depending on the size and state of the battery. Monitor the LCD
which should read over 13.4 volts when the battery is near full charge.
4. Once the Status LED comes on solid, unplug the

from the AC power
cable and turn on the Load Switch and Low Voltage Alarm. A weak battery will go down in voltage very quickly....
a good battery will last days before the alarm sounds. Repeat these steps until the length of time between alarms
increases to a long period of time. This indicates that the battery capacity has increased enough to be used again.
5. With the AC power disconnected a good battery will read approximately 12.6 volts and be able to hold this voltage.
Smaller batteries hold their voltage less than large batteries. The bigger the battery, the longer the voltage will stay up.
MAINTENANCE AND CARE
A minimal amount of care can keep your

working properly for years.
1. Clean the clamps each time you are finished charging. Wipe off any battery fluid that may have come in contact with the
clamps to prevent corrosion.
2. Coil the input and output cords neatly when storing the

. This will help prevent
accidental damage to the cords and charger.
HELPFUL REMINDERS:
• Never charge a frozen battery. If battery fluid (electrolyte) becomes frozen, bring battery into a warm area to allow the
battery to thaw before you begin charging.
• Never place the

battery will corrode and damage the

• Position the

• Do not operate the

PERSONAL SAFETY PRECAUTIONS
• Read all instructions and cautions printed on the

/M
aIntaIner

ester
, battery and vehicle or
equipment before using battery.
• Wear complete eye and clothing protection when working with lead-acid batteries.
• Make sure that someone is within range of your voice to come to your aid if needed while you work with or are near a
lead-acid battery.
• Have plenty of fresh water and soap nearby for use in case battery acid contacts your eyes, skin, or clothing. If this happens,
wash immediately with soap and water. Then get medical attention.
• Avoid touching your eyes while working with a battery. Wear safety glasses. Acid particles (corrosion) may get into your eyes.
If this occurs, flush eyes immediately with running cold water for at least 15 minutes. Then immediately get medical attention.
