EEBC500-INT
INTRODUCTION
BATTERY CHARGER PLUS
Thank you for purchasing your new Snap-on Battery
Charger plus.
The EEBC500-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 6 (3 cell), 12 (6 cell) and 24 (12 cell) volt batteries
on the market today; including AGM, GEL, Sealed Lead
Acid, Deep Cycle, Spiral-Cell and Standard Automotive
batteries up to 155 Ah capacity, reducing charge times while
maximizing battery life.
EEBC500-INT-Z
Engine Starting Power
The microprocessor is the heart of the multistage charging
algorithm built into the EEBC500-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.
00-99-000963/1109
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.

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 tractors, 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.
CHARGE RATE/CHARGING TIME IN HOURS
(unless otherwise stated)
4 AMP 15 AMP 60 AMP
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

1.225 75% 25%
1.155 25% 75%
1.120 0% 100%
PERCENT OF
CHARGE
PERCENT OF CHARGE
NEEDED
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.

REPLACING THE CLAMP CABLES
Remove the two screws on the cover plate, and tilt it out 1.
of the slots on the bottom.
2. Remove the screws on the terminals using a 6 mm hex
wrench. These will be torqued down tight, 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.
