BATTERY MANAGER IV FEATURES
• Simple Touch Button Control Panel
Allows quick and easy set-up for each specific
charging routine.
• 4-Stage Charging Process
The charger uses a proprietary 4-Stage charging
process designed to optimally charge and maintain
batteries. The charging process includes a soft start
mode to properly charge deeply discharged batter-
ies and is beneficial for the long-term health of your
batteries. The final stage in the charging routine is a
Maintenance Mode that allows the charger to be con-
nected indefinitely to a battery and maintain a proper
charge level.
• Multiple Battery Compatibility
The charger will properly charge a wide variety of
battery types, including Conventional, Maintenance
Free, AGM, Gel Cell and Deep Cycle batteries.
• Reverse Polarity Protection
Guards against reverse connections. Warning LED will
light on control panel, the unit will emit an audible
alarm and power will not be sent to output cables if a
reverse connection is sensed.
PREPARING TO CHARGE BATTERY
1. If it is necessary to remove battery from vehicle to charge, always remove grounded terminal from battery first.
Make sure all accessories in the vehicle are off, so as not to cause an arc.
2. Be sure area around battery is well ventilated while battery is being charged. Gas can be forcefully blown away by
using a piece of cardboard or other non-metallic material as a fan.
3. Clean battery terminals with a mixture of baking soda and hot water. Be careful to keep corrosion from coming in
contact with eyes.
4. Add distilled water in each cell until battery acid reaches level specified by manufacturer. This helps purge exces-
sive gas from cells. Do not overfill. For batteries without cell caps, follow manufacturer's recharging instructions.
5. Study all battery manufacturer's specific precautions such as removing or not removing cell caps while charging
and recommended rates of charge.
6. Determine voltage of battery by referring to vehicle owner's manual and make sure that output voltage.

• Multiple Output Options
The charger comes complete with both DC output
clips and ring terminals to allow a greater range of use
and improved convenience. Purchase additional ring
terminals for each of your vehicles to speed up charg-
ing set-up time and reduce hassle.
• Smart Clamp Technology
The charger will send power to the output leads only
when a proper battery connection is made.
• Battery Fault Protection
Guards against shorted or otherwise compromised
batteries. Situations that cause the fault condition
include connecting to a battery with a voltage less the
3V, connecting to a battery with a voltage above 15V
in 12V mode (7.5V in 6V mode), connecting to a bat-
tery with a shorted cell or a short-circuited battery or
if the charger diagnoses an incorrect voltage selection.
• Fully Enclosed Design
The charger utilizes a fully enclosed, IP65-compliant
design, preventing dirt, dust and grime from entering
the interior of the charger.
