INTRODUCTION

Description

This battery charger is designed to handle the majority of your charging and starting needs. It features:

• Automatic Multi-Phase Charging mode for easy operation.
• The ability to properly charge multiple battery types, including Flooded, AGM and Spiral Wound batteries.
• Multiple Charge Rates for various battery sizes.
• High-Amperage Engine Starting Assistance to start vehicles when the battery is weak.
• A stable power mode to maintain vehicle system voltage during on-vehicle repairs.
• Large Saw-Tooth Clamps assure good connection to top or side-mount battery terminals.
• Heavy-Duty Construction for long, trouble-free life.

How Batteries Charge

A battery charger does not force current into a battery – it makes a specific amount of current available to the 

battery and the battery draws as much of it as it needs, up to or slightly greater than the rated output current 

capability of the charger.
The closer a battery is to zero capacity (dead battery), the more charging current it will want to draw. When 

charging begins, on a dead battery, the charger will typically supply current at or very near the nominal chosen 

charging rate, and then move to a reduced rate of current as the battery becomes more fully charged. Keep in 

mind, a charger’s display shows the amount of current being drawn from the charger by the battery, not what the 

charger is capable of delivering.

Note: A slow, intermittent bubbling sound may be heard coming from the battery during the charging process. 
This is a normal condition and just another indicator the battery is being charged.

To reduce the risk of battery overcharging, it is important to thoroughly read this entire instruction manual.

How Stable Power Mode Functions

Your unit features 3 separate working modes: automatic battery charging mode, stable power mode, and engine 

start mode.
Stable Power mode is used to hold the voltage of the electrical system on a vehicle at a constant voltage for 

various service/maintenance functions. These include on-vehicle repairs of electronically controlled systems, 

diagnosis of electrical system component function or other applications where it is detrimental for the system 

voltage to drop below a specific threshold.  
In stable power mode, your unit will provide power to the vehicle’s electrical system so that system voltage 

remains at a steady level (as directed by you during stable power mode set-up) despite load changes the system 

experiences up to 60A (12V mode) 20A (24V mode) over an extended period of time.
NOTE: Stable power mode utilizes the vehicle’s battery to improve response times to load changes. As such, it 

is important to ensure the vehicle’s battery is in good condition and fully charged prior to initiating stable power 

mode.

Spark Prevention

Make sure no sparks or flames occur near the battery, especially during charging. It takes very little to ignite the 

explosive gasses produced by a lead-acid battery during the charging process. Read, understand and follow the 

safety information provided in the Safety Summary section of this manual before attempting to work with or near a 

lead-acid battery.
