IMPORTANT SAFETY INSTRUCTIONS

This manual contains important safety and operating instructions for the charger. Read
the entire manual before using. Also read all instructions and cautions for the charger,
batteries and equipment in the vicinity of the batteries.

WARNINGS

THIS CHARGER SHOULD BE USED TO CHARGE ONLY LEAD ACID, AGM OR
GEL CELL TYPE BATTERIES. USE ON OTHER BATTERY TYPES MAY EXPLODE
AND CAUSE PERSONAL INJURY.

RISK OF EXPLOSIVE GASES! WORKING IN THE VICINITY OF LEAD ACID
BATTERIES IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE GASES
DURING NORMAL OPERATION. THEREFORE IT IS OF THE UTMOST
IMPORTANCE THAT EACH TIME BEFORE USING YOUR CHARGER YOU
FOLLOW THE INSTRUCTIONS EXACTLY.

AC Connection and Grounding Precautions

DANGER

DO NOT OPERATE THIS CHARGER WITH A TWO BLADED ADAPTER PLUG OR
EXTENSION CORD. DOING SO CAN RESULT IN SERIOUS PERSONAL INJURY.

AFTER SECURING THE BATTERY CONNECTIONS, PLUG THE AC LINE CORD
INTO AN AVAILABLE AC OUTLET THAT IS PROTECTED BY A GROUND FAULT
CIRCUIT INTERRUPTER (GFCI) BREAKER.

CAUTION

TO REDUCE THE RISK OF SHOCK, CONNECT ONLY TO A PROPERLY
GROUNDED OUTLET

NOTE: AC Line Cord color-coding is EU style. Line = Brown, Neutral = Blue, Ground
= Green

INTRODUCING THE CHARGER

The Guest model 16041, 16082, and 16123 are designed to both recharge your
batteries, and extend your battery’s life in applications where it is stored for long
periods of time. They are “3-stage” electronic, completely automatic, lightweight, silent,
battery chargers and each output produces 12 Volts DC at a full 4 Amps (model
specific), while using much less AC current than other charger types. Unlike
automotive “trickle” chargers, the 16041, 16082, and 16123 will not boil off the
electrolytes in properly installed and maintained batteries. When the charger is
attached to your batteries and plugged into a standard 115 Volt / 60 Hz AC outlet, the
red and green LED’s, mounted on the face of the charger let you know the unit is
recharging and maintaining your batteries. This sophisticated device is ideal for
recharging and maintaining the 12VDC batteries in your boat, electric vehicle or cart,
ATV, snowmobile or motorcycle.

Personal Safety Precautions

Adhere to the following personal safety precautions when installing or working with the
chargers:

1.

Someone should be within voice range or close enough to come to your aid when
you work near a lead-acid battery.

2.

Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing, or eyes.

3.

Wear complete eye protection and clothing protection. Avoid touching eyes while
working near a battery.

4.

If battery acid contacts skin or clothing, wash them immediately with soap and
water. If acid enters the eye, flood the eye with cold, running water for at least ten
minutes and get medical attention.

5.

Never smoke or allow an open flame in the vicinity of the battery.

6.

Do not drop a metal tool onto the battery. It may short-circuit the battery, spark and
may cause an explosion.

7.

Remove all personal metal items such as rings, bracelets, necklaces, and watches
when working near a lead-acid battery. A battery can produce short circuit currents
high enough to weld a ring or the like to metal, causing a severe burn.

4

battery manufacturer, if applicable. Do not overfill. Check water levels frequently.

Preparing to Charge Precautions

Before charging a battery with the charger, read the following precautions:

1.

Do NOT operate the charger if the cable or an LED indicator is damaged.

2.

Make sure all accessories on the product you are charging are OFF.

3.

If the battery or batteries must be removed from the product, always remove the
grounded terminal from the battery first.

4.

Be sure the area around the battery is well ventilated while the battery is being
charged. Gas can be forcefully blown away using a piece of cardboard or other
non-metallic material as a “hand fan”.

5.

Clean battery terminals. Be careful to keep corrosion from coming into contact with
eyes.

6.

Add distilled water in each cell until battery acid reaches levels specified by the

For a battery without cell caps, carefully follow the manufacturer’s recharging
instructions.

7.

Never allow the charger battery connection ring terminals to touch each other.

8.

NEVER charge a frozen battery.

9.

Please be sure the DC system to which the charger is connected is not drawing
excessive current from the battery for extended periods of time while the charger is
operating. This is important to ensure the charger correctly transitions through each
charging stage to finish with the float voltage level. If the DC system is drawing
continuous current while charging, reduced life or damage to the battery may occur.

INSTALLING THE CHARGER

Note: The initial installation consists of (a) Choosing a mounting location, (b) mounting

the charger, (c) making the DC connections, (d) making the AC connections to a
receptacle that is protected by a GFCI breaker.

Choosing Charging Location

The charger should have at least eight inches of unobstructed area on all sides of the
unit for effective cooling. The case of this charger will become warm during operation.
Because the charger is convection cooled (airflow over the back heat sink, the optimum
mounting position for the charger is vertical. Mounting on its back on a horizontal
surface may cause the charger to slightly reduce amperage output due to the thermal
protection built in. Do not install the charger on carpeted, upholstered, or varnished
surfaces.

Mounting the Charger

1.

Use corrosion resistant #10 sized bolts, backed by a flat washer, and secured to the
mounting surface with a split-ring lock washer.

2.

Hold the charger to the mounting surface and mark the holes.

3.

Remove the charger and drill the mounting holes.

4.

Align the charger and assemble the mounting hardware. Secure.

Making the DC Connections

Check polarity of the battery posts. The POSITIVE (POS., P, +) battery post usually
has a larger diameter than the NEGATIVE (NEG., N, -) post. Connect Red charger
output wire to POSITIVE post, Black charger wire to NEGATIVE. See below diagrams
for more details.

Making AC Connection

After making DC connections, connect the AC plug into an AC receptacle, which is
protected by a Ground Fault Circuit Interrupter (GFCI) breaker.

Battery Size Recommendations

The recommended maximum battery size per bank is 75AH (Group 24).

Note: Transition from Absorption stage to float stage is affected by the size of the
batteries. Larger batteries may stop the charger from transitioning to float stage due to
excessive self discharge current in the battery.
