INTRODUCTION

BATTERY CHARGER PLUS

Thank you for purchasing your new Snap-on Battery

Charger Plus.

The EEBC500B 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 also has the ability to boost the voltage

on 24V (12 cell) batteries. (The EEBC500B does not fully

charge 24V batteries).

The microprocessor is the heart of the multistage

charging algorithm built into the EEBC500B.

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 specied

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 specied 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.

Features

• 10-in. Diameter Foam-Filled Wheels –

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 specication 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.

15. ERROR CODES

If you get an error code, check the connections and settings and/or replace the battery.

CODE DESCRIPTION REASON/SOLUTION

01

The battery voltage is still under 10V (for a

12V battery) or 5V (for a 6V battery) after 2 hours

of charging.

The battery could be bad. Have it checked or replaced.

02

The charger cannot desulfate the battery. The battery could not be desulfated; have it checked or replaced.

03

The battery was unable to reach the “full charge”

voltage.

May be caused by trying to charge a large battery or bank of batteries

on too low of a current setting. Try again with a higher current setting or

have the battery checked or replaced.

04

The connections to the battery are reversed. The battery is connected backwards. Unplug the charger and reverse

the connections to the battery.

05

The charger was unable to keep the battery fully

charged in maintain mode.

The battery won’t hold a charge. May be caused by a drain on the

battery or the battery could be bad. Make sure there are no loads

on the battery. If there are remove them. If there are none, have the

battery checked or replaced.

06

The charger detected that the battery may be

getting too hot (thermal runaway).

The charger automatically shuts the current off if it detects the battery

may be getting too hot. Have the battery checked or replaced.

16. TROUBLESHOOTING

Performance problems often result from little things that you can x yourself. Please read through this table for a possible solution

if a problem occurs.

PROBLEM POSSIBLE CAUSE SOLUTION

No reading or 0.0V shown

on the display.

Clamps are not making a good

connection.

AC cord and/or extension cord is loose.

No power at receptacle.

Clamp polarity reversed.

Check for poor connection at battery and frame. Make sure

connecting points are clean.

Check power cord and extension cord for loose tting plug.

Check for open fuse or circuit breaker supplying AC outlet.

Verify and reverse the battery clamps.

The

Boost/Charging

LED is ashing.

The charger has stopped in Boost or one

of the charge modes.

The battery is bad.

The charger cannot complete the boost or charge. Have the

battery checked and replace, if necessary.

Disconnect charger from the AC outlet and then remove the

clamps. Do not continue to try to charge the battery. Have

the battery checked and replace, if necessary.

The

Boost/Charging

LED does not turn off.

The charger is still in Boost mode.

The charger is still in one of the charge

modes.

This is normal. In Boost mode, the

LED will not turn off

until the battery is disconnected from the charger.

This is normal. In one of the charge modes, the

TROUBLESHOOTING, continued

PROBLEM POSSIBLE CAUSE SOLUTION

Short or no start cycle

when cranking engine.

Failure to wait 3 minutes (180 seconds)

between cranks.

Clamps are not making a good

connection.

AC cord and/or extension cord is loose.

No power at receptacle.

The charger may be overheated.

Battery may be severely discharged.

Wait three minutes or until the display reads  and the

LED is on.

Check for poor connection at battery and frame. Make sure

connecting points are clean.

Check power cord and extension cord for loose tting plug.

Check for open fuse or circuit breaker supplying AC outlet.

The internal thermal protector may have tripped and needs

a little longer to close. Wait until it automatically resets and

try again.

On a severely discharged battery, wait for 10 to 15 minutes

in Engine Start mode, to help assist in cranking.

Charger makes a loud buzz. Transformer laminations vibrate. No problem; this is a normal condition.

Battery % stays low during

charging.

Battery is severely discharged.

Wrong battery voltage selected.

Continue charging battery for two more hours. If problem

continues; call your Snap-on representative.

Make sure BATTERY VOLTAGE switch is properly set for

6V, 12V or 24V selection.

The “Maintain” and “Fast

Charge” rates do not work

on the 24V setting.

Complete charge of a 24 Volt battery is

not a function of this unit.

This charger does not fully charge 24V batteries. It boosts

the voltage to 27.2V and holds the voltage at this level.

Clicking noise from

charger.

Circuit breaker is cycling.

Battery is defective.

Shorted battery clamps.

Severely discharged battery, but

otherwise a good battery.

Reversed connections at battery.

Under certain conditions, this unit has a high capacity and

the circuit breaker protects the unit under these conditions.

If the circuit breaker is cycling often, stop the operation by

pressing the START/STOP button and wait until the unit has

cooled, to return to operation.

Have the battery checked.

Circuit breaker cycles when current draw is too high.

Check for shorted cables and replace if necessary.

Allow charging to continue until battery has a chance to

recover sufciently to take a charge. If more than 20 minutes,

stop charging and have the battery checked.

Correct the lead connections.

Display shows “SUL” The battery is sulfated. A sulfated battery may eventually take a normal charge if left

connected. The charger will continue to charge with a low

current for up to 10 hours to recover the battery. If the battery

will not take a charge after 10 hours, have it checked.

Engine start does not work. Vehicle drawing more than 300 amps

(6V/12V) and 250 amps (24V).

Failure to wait 3 minutes (180 seconds)

between cranks.

The charger may be overheated.

Battery may be severely discharged.

Crank time varies with the amount of current drawn. If crank-

ing draws more than 300 amps, crank time may be reduced.

When the Engine Start LED blinks, wait 3 minutes of rest

time before the next crank.

The thermal protector may have tripped and needs a

little longer to reset. Make sure the charger vents are not

blocked. Wait and try again.

On a severely discharged battery, use the Boost rate for 10

to 15 minutes, to help assist in cranking.

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.
