INTRODUCTION
BATTERY CHARGER PLUS
Thank you for purchasing your new Snap-on Battery
Charger Plus.
The EEBC500B-INT is an advanced, full featured battery
charger with additional functions that make it a battery
service system.
The charger utilizes a microprocessor, controlling both
the voltage and current going to the battery, providing
maximum power and the precise control needed to
charge the various types of 6V (3 cell) and 12V (6 cell)
batteries on the market today, including LiFePO
4
, AGM,
Sealed Lead-Acid, Deep-Cycle, Spiral-Cell and Standard
Automotive batteries, reducing charge times while
maximizing battery life.
The EEBC500B-INT also has the ability to boost the
voltage on 24V (12 cell) batteries. (The EEBC500B-INT
does not fully charge 24V batteries).
The microprocessor is the heart of the multistage
charging algorithm built into the EEBC500B-INT.
Microprocessor-based charging technology achieves
an extremely versatile charging algorithm, and provides
a user-friendly set of controls and an easy-to-read
digital display (voltage, % of charge, alternator % of
performance). The versatility allows many different
battery types to be charged.
Flash Reprogramming Power Supply
Provides a consistent power at the OEM specied
voltage (user entered) to allow for uninterrupted ash
reprogramming of vehicle’s computers or to retain vehicle
system settings.
When reprogramming, the power supplied to the vehicle
module must not drop below OEM specied voltage.
Some reprogramming operations with the key-on will turn
on cooling fans, fuel pumps, and other components that
will cause the battery to drain faster than normal. Instead
of pulling fuses to prevent the battery drain, it is easier
and more practical to have the vehicle connected to a
constant voltage power supply. During reprogramming,
there is a risk of having the operation fail if the voltage
falls below the proper operating voltage. Sometimes a
failed operation can be recovered, but there is a chance
that failed reprogramming could ruin the control module.

within a few seconds the battery is bad or heavily
sulfated. Do not perform an “Engine Start”
operation on this battery.
c. The bad battery could allow the charger to sup-
ply a high enough voltage in Engine Start mode to
damage the vehicle electrical system (similar to the
“no battery” warning stated above in item #1).
2. Set the Battery VOLTAGE to 6V, 12V or 24V.
3. Set the OUTPUT RATE to ENGINE START.

minutes before cranking the engine.
6. Wait three minutes before attempting to start again.
The digital display will indicate the time remaining
before cranking again and the ENGINE START LED
will blink.
NOTE: During this cool down period, the charger is
supplying the battery with a charge of up to 10A.
7. When the digital display times down to 0 and reads
, the Engine Start LED has stopped blinking and
the Charging LED is on, you are ready to crank
the vehicle again. You have three minutes to perform
an engine start (Pressing the Start/Stop button is
NOT REQUIRED.)
8. If the engine still does not start, allow the charger
to charge the battery for ve more minutes before
cranking it again.
9. After the engine starts, unplug the charger power
cord from the wall outlet, before disconnecting from
the battery.
If the engine does turn over, but never starts, there is
not a problem with the starting system; there is a problem
somewhere else with the vehicle. STOP cranking the
engine until the other problem has been diagnosed and
corrected.
FLASH REPROGRAMMING
Not for use with LiFePO
4
batteries.
NOTE: Do not attempt to Flash Reprogram a vehicle
that has a discharged or defective battery. Make sure
that the vehicle battery is in good condition and FULLY
CHARGED before proceeding.
The EEBC500B-INT is designed to supply up to 100 amps
in “Flash Reprogram” mode.
Some newer vehicles may require more than 100 amps
while ash reprogramming the ECU. Consult the vehicle
manufacturer’s specications to determine the required
amperage. The EEBC500B-INT “Flash Reprogram” mode
cannot be used on vehicles that require more than 100 amps,
or damage to the ECU and/or vehicle’s electrical system
may occur. Failure to follow these instructions may also
damage the service center’s ash reprogram equipment.
1. Set BATTERY VOLTAGE to FLASH REPROGRAMMING.
2. Use “UP” and “DOWN” buttons to adjust the voltage
needed for the vehicle being programmed (refer to
OEM specications). Voltage selected is shown on
the digital display. The unit has a voltage range of
13.0 to 14.8, with a default of 14.2.
NOTE: When the VOLTS LED stops blinking, the
display shows the selected voltage.
3. Press START/STOP to activate the output.
NOTE: During this time, the other buttons will not
work until you turn off the output. When the display
shows no buttons will work for ve seconds, then
it automatically goes back to the default state.

13. CALCULATING CHARGE TIMES
The Chart Method
Use the following table to more accurately determine the
time it will take to bring a battery to full charge.
First, identify where your battery ts into the chart.
• Small batteries – motorcycle, garden tractor, etc. –
are usually rated in Ampere hours (Ah).
For example: 6, 12, 32 Ah, etc.
• Batteries in cars and smaller trucks are usually rated
in Reserve Capacity (RC), Cold-Cranking Amps
(CCA), or both.
• Marine or deep-cycle batteries are usually rated in
Reserve Capacity (RC).
• NR means that the charger setting is NOT
RECOMMENDED.
Find your battery rating on the chart below and note
the charge time given for each charger setting. The
times given are for batteries with a 50-percent charge
prior to recharging. Add more time for severely discharged
batteries.

The Hydrometer or Electronic Method
To nd the time needed to fully charge your battery,
determine the battery’s charge level with a hydrometer or
electronic Percent-of-Charge Tester. The following table
will help you convert hydrometer readings to percent of
charge values.
SPECIFIC
GRAVITY
PERCENT OF
CHARGE
PERCENT OF CHARGE
NEEDED
1.265 100% 0%
1.225 75% 25%
1.155 25% 75%
1.120 0% 100%
When you know the percent of charge and the
Amp hour (Ah) rating of your battery, you can calculate
the approximate time needed to bring your battery to a full
charge.
To convert Reserve Capacity to Amp hours, divide
Reserve Capacity by 2, and add 16:
Example:
Amp hour Rating = Reserve Capacity + 16
2
NOTE: The reserve Capacity can be obtained from the
battery specication sheet or the owner’s manual.
To calculate time needed for a charge:
• Find the percent charge needed. (A battery at 50%
charge that will be charged to 100% needs another
50% [.50]).
• Multiply the Amp Hour rating by the charge needed
(.50) and divide by the charger setting (4, 15, or
60 amps).
• Multiply the results by 1.25 and you will have the total
time needed, in hours, to bring the battery to
full charge.
• Add one additional hour for a deep-cycle battery.
Example:
Amp hour Rating x % of charge needed x 1.25 = hours of charge
Charger Setting
100 (Ah Rating) x .50 (charge needed) x 1.25 = 3.125 hours
20 (Charger Setting)
100 x .50 x1.25 = 3.125
20
You would need to charge your 100-Ampere hour Battery
for a little more than three hours at the 20-Amp charge
rate using the above example.

18. REPLACING THE CLAMP CABLES
1. Remove the two screws on the cover plate, and tilt it
out of the slots on the bottom.
2. Remove the screws on the terminals using a 6 mm
hex wrench. These will be tight (torque 45-50 in-lbs.),
so you will probably need to use the long end. Take
care when removing the screws to prevent stripping
the hole. To prevent damage, it is recommended you
use an open ended wrench to keep the terminal
from spinning.
3. The strain reliefs are held in by three spring tabs.
While pulling on the cable (opposite side of strain
relief), push on the bottom tab to get it out rst, then
squeeze the two side tabs together to remove the
strain relief from the hole.
4. Follow these steps in reverse to assemble the
new cable.

EEBC500B-INT-Z
INTRODUCCIÓN
CARGADOR DE BATERÍAS PLUS
Gracias por comprar su nuevo Cargador de baterías Plus
de Snap-on.
El EEBC500B-INT es un cargador de baterías avanzado
con nuevas características y funciones adicionales.
El cargador utiliza un microprocesador, que controla el
voltaje y la corriente que pasa a la batería, proporcionando la
máxima potencia y el control preciso necesarios para cargar
los diversos tipos de baterías de 6 V (3 células) y 12 V (6
celdas) voltios en el mercado actual, entre otras: LiFePO
4
,
AGM, de ácido de plomo sellado, ciclo profundo, de placas
en espiral y estándar de automóvil. El cargador reduce los
tiempos de carga y maximiza la vida útil de las baterías.
EEBC500B-INT también tiene capacidad para potenciar el
voltaje en baterías de 24 (12 celdas). (EEBC500B-INT no
carga completamente las baterías de 24 V).
El microprocesador es el núcleo del algoritmo de carga
de etapas múltiples incorporado al EEBC500B-INT. La
tecnología de carga en base a un microprocesador ofrece
un algoritmo de carga sumamente versátil y brinda una
serie de mandos de manejo sencillo y una pantalla digital
de fácil lectura (voltaje, % de carga, % de rendimiento del
alternador) Su versatilidad permite la carga de una amplia
gama de baterías de distintos tipos.
Suministro de energía para reprogramación
del punto de ignición
Provee energía constante al voltaje especicado por el
fabricante del equipo original (a ingresar por el usuario)
permitiendo la reprogramación del punto de ignición de
computadoras de vehículos de manera interrumpida o el
mantenimiento de la conguración del sistema de un vehículo.
Durante la reprogramación, la energía suministrada al módulo
del vehículo no debe caer por debajo del voltaje especicado
por el fabricante del equipo original (OEM, por sus siglas en
inglés). Algunas operaciones de reprogramación realizadas
con la llave en encendido encenderán los ventiladores de
refrigeración, bombas de combustible y otros componentes
que harán que la batería se agote más rápidamente de lo
normal. En lugar de quitar fusibles para evitar el agotamiento
de la batería, resulta más sencillo y práctico conectar el
vehículo al suministro de energía de voltaje constante.
Durante la reprogramación, existe el riesgo de que la
operación falle si el voltaje cae por debajo del voltaje operativo
adecuado. En algunas ocasiones, una operación fallida
puede ser recuperada, pero existe la posibilidad de que la
reprogramación fallida arruine el módulo de mando.
Características
• Ruedas de 10 pulgadas de Diámetro, Rellenas de
unicel – que permite el movimiento fácil en el taller
o el suelo.
• Pantalla digital: % de carga, voltaje, rendimiento
del alternador – muestra datos precisos.
• Compartimiento portaherramientas con tapa: espacio
útil para guardar herramientas utilizadas en el
mantenimiento de baterías.
