1.INTRODUCING THE CHARGER
The Guest model 2608A-B-01 is designed to both recharge your batteries, and extend
your battery’s life in applications where it is stored for long periods of time. The 2608A-
B-01 is a “2-stage” electronic, completely automatic, lightweight, silent, battery charger
and produces 12 Volts DC at a full 6 Amps, while using much less AC current than
other charger types. Unlike automotive “trickle” chargers, the 2608A-B-01 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 let you know the unit is recharging and maintaining your batteries.
This sophisticated device is ideal for recharging and maintaining the 12VDC battery.
2. IMPORTANT SAFETY INSTRUCTIONS
1. This manual contains important safety and operating instructions for the charger.
Read the entire manual before using. Also read all instructions and cautions for
and on the charger, batteries and equipment in the vicinity of the batteries.
2. Use of an attachment not recommended or sold by Guest may result in a risk of
fire, electric shock, or injury to persons.
3. To reduce the risk of damage to electric plug and cord, pull by plug rather than
cord when disconnecting charger.
4. An extension cord should not be used unless absolutely necessary. Use of
improper extension cord could result in a risk of fire and electric shock. If an
extension cord must be used, ensure:
a. the pins on the plug are the same number, size and shape as those on
the charger
b. The extension cord is properly wired and in good electrical condition
c. The extension cord wire size is 18AWG (up to 100ft) or 16AWG (up to
150ft), and
d. The extension cord length is as short as possible
5. Do not operate the charger with a damaged cord or plug.
6. To reduce the risk of injury unplug charger from outlet before attempting any
maintenance or cleaning. Turning off controls alone will not reduce this risk.
7. Do not operate the charger if it has received a sharp blow, been dropped, or
otherwise damaged in any way; take it to a qualified serviceman

WARNINGS
THIS CHARGER SHOULD BE USED TO CHARGE ONLY 12 VOLT DC LEAD ACID
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.
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 spark, short circuit the battery 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.
8. Use charger for charging a LEAD-ACID or GEL Battery only. It is not intended to supply power
to a low voltage electrical system other than in a starter motor application. Do not use battery
charger for charging dry cell batteries that are commonly used with home appliances. These
batteries may burst and cause injury to persons or damage to property.
9. NEVER charge a frozen battery.

Preparing to Charge Precautions
Before charging a battery with the charger, read the following precautions:
1. Do NOT operate the charger if the cables or an LED is damaged.
2. If the battery or batteries must be removed from the product, always remove the
grounded terminal from the battery first. Make sure all accessories on the product
you are charging are OFF.
3. 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”.
4. Clean battery terminals. Be careful to keep corrosion from coming in contact with
eyes.
5. Add distilled water in each cell until battery acid reaches levels specified by the
battery manufacturer. Do not overfill. For a battery without cell caps, carefully
follow the manufacturer’s recharging instructions.
6. Study all battery manufacturer’s specific precautions while charging and
recommended rates of charge.
7. Never allow the 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.
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.
Never alter the AC cord or plug provided – If it will not fit outlet, have proper
outlet installed by a qualified electrician. Improper connection can result in a
risk of an electric shock.
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

3.INSTALLING THE CHARGER
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.
Do not install the charger on carpeted, upholstered, varnished surfaces, directly above
or below the battery. Keep the AC power cord connection as short as possible
especially when using an extension cord. Locate the charger as far away from the
battery as the DC cables permit.
Mounting the Charger
1. Use corrosion resistant ¼” dia. 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 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 / White
charger output wire to POSITIVE post, Black charger wire to NEGATIVE. See below
diagrams for more details.
Battery Size Recommendations
The recommended maximum battery size is up to 150Ahrs.
Making AC Power Connections
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. Keep the AC
power cord connection as short as possible especially when using an extension cord.

4.OPERATING THE CHARGER – 6 amp output
The LED Function Chart describes the charging process for any individual 6 Amp output.
Display Operating condition
When the red LED is on, it indicates that your battery is discharged and is
recharging at the "BULK" rate. This charging rate is approximately 5 to 6
Amps.
While the red LED is on, the voltage measured (with the charger on) will be
11.0 to 13.6 Volts.
If the red LED stays on for more than 24 hours, refer to Problem 1 in the
troubleshooting section in this manual.
When both the green and the red LED’s are on, the 2608A-B-01 is charging at
a "Midrange" rate and the current is between 2 to 5.5amp. This mode of
charging gradually “tops off “ your battery, and reduces harmful sulfating.
While both LED’s are on, the voltage measures (with the charger on) should
be approximately 13.0 to13.6VDC.
If both lights stay on longer than 24 hours, refer to Problem 2 in the
troubleshooting section in this manual.
When the green LED in on, the 2608A-B-01 is charging at a “FLOAT” or
“MAINTENANCE” rate of less than 2amps and a battery voltage of
approximately 13.3VDC. Your battery is now 90% charged and ready for use.
This “FLOAT” charging current will gradually decrease to as low as 0.1 Amps
as the battery reaches 100% charged.
If the green LED stays on when your battery is known to be low, refer to
Problem 3 in the troubleshooting section in this manual.
