DESCRIPTION

This battery charger is designed to handle the majority of

your charging and starting needs.

MULTIPLE CHARGE RATES for various battery sizes.

High-AMPERAGE ENGINE START to help start vehi-

cles when the battery is too weak to do the job alone.

An AMMETER to monitor charging progress

A TIMER switch to set the desired charge time.

LARGE SAW-TOOTH CLAMPS assure good connec-

tion to top or side-mount battery terminals.

WHEEL AND HANDLE KIT for easy moving around

your shop.

HEAVY-DUTY CONSTRUCTION for long, trouble-free

life.

HOW BATTERIES CHARGE

A charger DOES NOT FORCE current into a battery - it

makes a limited amount of current available 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 charge (dead battery), the

more charging current it will want to draw. When charging

begins, on a dead battery, the chargers ammeter will regis-

ter toward the high end of the ammeter scale and move

toward zero as the battery becomes more fully charged.

KEEP IN MIND, the ammeter registers the amount of

amperage being drawn from the charger by the battery, not

what the charger is capable of delivering.

One would expect a battery to draw zero amps when it

reaches 100% charge. But at 100% charge, the battery will

continue to draw a low level of current and convert it into

heat within the battery. If left connected and charging after

reaching 100% charge, the battery acid will begin to boil,

resulting in overcharging and possible battery damage.

INTRODUCTION

NOTE: A slow 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 instruction manual.

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. Read,

understand, and follow the safety information provided in the

SAFETY SUMMARY section of this manual before attempt-

ing to work with or near a lead-acid battery.

For more information about batteries and battery charging,

contact Battery Council International at (312) 644-6610, and

request their BATTERY SERVICE MANUAL, which is avail-

able for a nominal charge.

DEEPLY-DISCHARGED LEAD-CALCIUM

BATTERIES

Many newer automotive batteries are of a lead-calcium plate

design. When deeply discharged, they may require an acti-

vation period before accepting a measurable charge. This

activation period may take as long as 4 to 8 hours.

If, at the beginning of the charging process, you notice that

the ammeter (if so equipped) is at or near zero, but you

have determined that the battery is very discharged (less

than 25% of charge), this is a good indication that an activa-

tion period is required (see PRE-CHARGE BATTERY ACTI-

VATION).
