1. INTRODUCING THE CHARGER
The Guest model 2614A, 2621A, and 2622A are designed to 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, lightweight, silent, completely automatic battery chargers.
Each output produces 12 Volts DC at a full 5 Amps or 10 Amps (model specific), while
using much less AC current than other charger types. Unlike automotive “trickle”
chargers, the 2614A, 2621A, and 2622A will not boil off the electrolytes in properly
installed and maintained batteries. The red and green LED’s, mounted on the charger
face 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.
SAVE THESE INSTRUCTIONS
WARNINGS
THIS CHARGER SHOULD BE USED TO CHARGE ONLY LEAD ACID, AGM, OR
GEL CELL TYPE BATTERIES. USE ON OTHER BATTERY TYPES MAY CAUSE
AN EXPLOSION OR 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.
Perso al Safety Precautio s
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.

3
7. emove 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.
Prepari g to Charge Precautio s
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. 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 in contact with
eyes.
6. Add distilled water in each cell until battery acid reaches levels specified by the
battery manufacturer, if applicable. Do not overfill. For all batteries, carefully follow
the manufacturer’s recharging instructions.
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.

Circuit Breaker Operatio for chargers equipped with circuit breakers:
For chargers equipped with circuit breakers, the circuit breaker will trip, or open, during
an overcurrent situation. This can be caused by connecting the charger in reverse
polarity across the battery. To reset the breaker, first disconnect the charger from the
battery, then push the circuit breaker button. Then reconnect the charger to the battery
using correct polarity.
Output Cable Fusi g: Guest Recomme ds that all chargers be i stalled with a
i -li e fuse o each DC positive output per ABYC sta dards
If the Guest Cruising Series charger does not come equipped with circuit breakers, an
inline fuse must be installed in series with each DC positive output cable to the battery.
This is to prevent catastrophic destruction of the charger in the event of reverse
polarity connection.

Choosi g Chargi g Locatio :
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 of the charger), 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.
Mou ti g 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. emove the charger and drill the mounting holes.
4. Align the charger and assemble the mounting hardware. Secure.
Battery Size Recomme datio s
The recommended maximum battery size per 5 amp bank is 60AH.
The recommended maximum battery size per 10 amp bank is 120AH.

4. OPERATING THE CHARGER – 10 (or 5/5) amp output
The LED Fu ctio Chart describes the chargi g process for a y 10 (or 5/5) Amp output.
Display Operati g co ditio
When the red LED is on, it indicates that your batteries are discharged and is
recharging them at the "Charging" rate (stage 1). This charging rate is 10 (or
5/5) Amps.
While the red LED is on, the voltage measured (with the charger on) will be
approximately 11.5 to 13 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, it is charging at the
"Finishing" rate. (stage 2). During this second charging stage, the charger
holds the battery voltage at approximately 14.3 VDC, and then gradually
reduces the amount of current (Amps) it delivers to the battery. By doing this,
the battery is able to “absorb” the last 10% of charge as quickly as possible
without becoming overheated.
If both lights stay on longer than 24 hours, refer to Problem 2 in the
troubleshooting section in this manual.
When the battery approaches full charge, the charger switches into its third
charging stage, gradually reducing the current fed to the batteries to as low as
0.1 Amps. At the same time, it reduces its output voltage to a “Float” or
“ eady” charging rate of approximately 13.3 VDC, indicated by the green LED
light. This low “Float” or “Maintenance” voltage gently “tops off” your
batteries, keeping them fully charged and ready until needed. The green LED
indicates that your batteries are now fully charged and ready for use.
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.

When the red LED is on, it indicates that your batteries are discharged and is
recharging them at the "Charging" rate (stage 1). This charging rate is 5
Amps.
While the red LED is on, the voltage measured (with the charger on) will be
approximately 11.5 to 13 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, it is charging at the
"Finishing" rate. (stage 2). During this second charging stage, the charger
holds the battery voltage at approximately 14.8 VDC, and then gradually
reduces the amount of current (Amps) it delivers to the battery. By doing this,
the battery is able to “absorb” the last 10% of charge as quickly as possible
without becoming overheated.
