OVERVIEW
Using this battery charger is very simple. First, connect the battery and AC power following the precautions listed under "OPERATING INSTRUCTIONS". Then select the appropriate CHARGE TYPE and CHARGE RATE for your battery. The char- ger will then do everything automatically. This section explains a few details.
CHARGING: If the charger does not detect a properly connected battery, the CHECK (red) LED wilt light continuously until such a battery is detected. Charging will not begin while the CHECK LED is on. When charging begins, the CHARGING LED will be lit.
AUTOMATIC SHUT OFF: When the 2A, 15A or 40A charge rate is selected, the charger is set to perform an automatic charge. When an automatic charge is performed, the charger stops charging automatically after the battery is charged.
ABORTED CHARGE: If charging can't be completed normally, charging will be aborted. When charging is aborted, the charger's output is shut off and the red CHECK LED and digital display blink on and off (at opposite times). In that state, the charger ignores all buttons. To reset from after an aborted charge, either disconnect the battery or unplug the charger.
DESULFATION MODE: If a battery is left discharged for an extended period, it could become sulfated and not accept a normal charge. If the charger detects a sulfated battery, the charger will switch to
a special mode of operation designed for such batteries. Activation of the special desulfation mode is indicated by blinking the CHARGING LED. If successful, nor-
mal charging will resume after the battery is desulfated. The CHARGING LED will
then stop blinking and light continuously. Desulfation could take up to 10 hours. If desulfation fails, charging will be aborted and the CHECK (red) LED will blink.
COMPLETION OF CHARGING: Charge completion is indicated by the CHARGED (green) LED; when tit, the charger has stopped charging and switched to the Maintain Mode of operation, if the DEEP CYCLE charge type was selected. For other charge types, the CHARGED LED comes on when the battery is charged enough for normal use.
MAINTAIN MODE: When the CHARGED (green) LED is tit, the charger has started Maintain Mode. This mode of operation is also known as
GENERAL CHARGING NOTES: The charger is designed to control its cooling fan for efficient operation. Consequently, it is normal for the fan to start and stop when maintaining a fully charged battery. The fan does not run in Tester Mode.

DISPLAY MODE SWITCH
Use this switch button to set the function of the digital display to one of the following.
???BATTERY %: The digital display shows an estimate of the percent of charge of the battery connected to the charger battery clamps.
???VOLTAGE: The digital disptayshows the voltage at the charger battery clamps in DC volts.
ALTERNATOR %: The digital display shows an estimated percentage of the output of the vehicle charging system connected to the charger battery clamps as compared to a properly functioning system.
CHARGE TYPE SWITCH
Use this switch button to set the type of battery to be charged to one of the fol- lowing.
???REGULAR: This is the type of battery usually used in cars, trucks, and motor- cycles. These batteries have vent caps and are often marked "tow maintenance" or
???DEEP CYCLE: Deep cycle batteries are usually marked as "deep cycle" or "marine". Deep cycle batteries are usu- ally larger than the other types.
???AGM/GEL: AGM and get cell batteries have sealed cases without vent caps. Such batteries are often smaller than the other types.
TOP OFF: Use the Top Off charge if your battery is not fully charged, but close enough to cause the charger to quickly change to the Maintain mode after one of the other charge types is started. Se- lecting Top Off will cause the charger to advance to the later stages of its charging process then change to regular maintain mode after charging is complete.
With the exception of AGM and get cell batteries, all other battery types may or may not have vent caps. Vent caps are located on top of the battery and provide a means to add distilled water when needed.
Batteries should be marked with their type. If charging a battery that is not marked, check the manual of the item that uses the battery. If the battery type is unknown, use the REGULAR setting. Make sure the battery complies with the safety instruc- tions on page 3.
CHARGE RATE SWITCH
Use this switch button to set the charge rate to one of the following.
2ASLOWCHARGE RATE: Intended for charging small batteries such as those commonly used in garden tractors, snow mobiles and motorcycles. The 2A rate is not intended to be used as a trickle charger for larger batteries.
???15A FAST or 40A RAPID CHARGE RATE: Use for charging automotive batteries, marine batteries, and deep cycle batteries. Not intended for industrial applications.
???125A START: Provides 125 amps for cranking an engine with a weak or run down battery. Always use in combination with a battery.
NOTE: To turn OFF the charger, unplug from the power cord from the wall outlet.
71226 CONTROL PANEL GUIDE
OVERVIEW
This battery charger has a
TESTING SEQUENCE
There are four basic steps required to use the 71226 as a battery tester.
1.Connect the charger battery clamps to the battery. Be sure to follow all of the precautions listed under "OPERATING
INSTRUCTIONS".
2.Connect the charger power cord to a 120V AC
3.If necessary, press the BATTERY
TYPE button until the correct type is indicated.
4.Read the voltage on the digital display or press the display mode button to set the tester to BATTERY % and read the battery percent.
TESTER AND CHARGER
When first turned on, the 71226 oper- ates only as a tester, not as a charger. To continue to use it as only a tester, avoid pressing the CHARGE RATE switch but- ton. Selecting a charge rate activates the battery charger and deactivates the tester. Pressing the CHARGE RATE button when the 125A Start LED is lit (except during the 180 second cool down) will shut off the charger and activate the tester.
POWER=UP IDLE TIME LIMIT
If no switch button is pressed within 15 minutes after the charger is first powered up, the charger will automatically switch from tester to charger, if a battery is connected. In that case, the charger will be set for the 2A charge rate and 12V REGULAR charge type.
TESTER WITHOUT TIME LIMIT
If either the DISPLAY MODE or CHARGE TYPE button is pressed within the first ten minutes after the charger is
11
powered up, the charger wilt remain a tester (not a charger) indefinitely, unless a charge rate is selected,
TESTING AFTER CHARGING
After the charger has been changed from tester to charger (by selecting a charge rate), it remains a charger. To change
the charger back to a tester, press the CHARGE RATE switch until all CHARGE
RATE LEDs are OFF.
TESTER STATUS LEDs
When the 71226 is operating as a bat- tery tester, the status LEDs light under the following conditions:
???The CHARGED (green) LED will light if a charged battery is tested.
???The CHARGING (yellow) LED does not light in the battery test mode.
???The CHECK (red) LED lights unless a properly connected battery is detected.
???When the tester display mode is set to VOLTAGE, the CHARGED and CHARG- ING LEDs won't light.
INITIAL PERCENT CALCULATION
When a battery % is calculated for the first time after connecting a battery, the digital display will show three dashes
NOTES FOR TESTING BATTERY %
A recently charged battery could have a temporarily high voltage due to what is known as "surface charge". The volt- age of such a battery will gradually drop during the period immediately after
the charging system is disengaged. Consequently, the tester could display inconsistent values for such a battery. For a more accurate reading, the surface charge should be removed by temporar- ily creating a load on the battery, such as by turning on lights or other accessories.
The battery % ranges from 0 to 100.
The battery tester is only designed to test batteries. Testing a device with a rapidly changing voltage could yield unexpected or inaccurate results.

TESTING SEQUENCE
There are three basic steps required to use the 71226 as an alternator tester.
1.Connect the charger battery clamps to the battery or charging system. Be sure to follow all d the precautions listed under "OPERATING INSTRUCTIONS".
2.Connect the charger power cord to a 120VAC
3.Start the vehicle and turn on the vehicle's headlights. Read the voltage on the digital display or press the DISPLAY MODE button to set the tester to ALTERNATOR % and read the alternator percent.
TESTER STATUS LEDs
When the 71226 is operating as an alter- nator tester, the status LEDs light under the following conditions.
???The CHARGED (green) LED will light if the output of the charging system is at the normally desired level.
???The CHARGING (yellow) LED does not light in the alternator test mode.
???The CHECK (red) LED lights if the VOLTAGE is much higher or lower than normally desired.
???When the tester display mode is set to VOLTAGE, the CHARGED and CHARGING LEDs won't light (it could be testing a battery or an alternator).
ALTERNATOR TESTING NOTES
???The alternator percent display can range from 0 to 199.
???The DISPLAY MODE cannot be set to ALTERNATOR % during charging.

This charger adjusts the charging time in order to charge the battery completely, efficiently and safely. The microproces- sor automatically makes the necessary decisions. However, this section includes guidelines that can be used to estimate charging times.
The duration of the charging process depends on three factors:
1.Battery State - If a battery has only been slightly discharged, it can be charged in less than a few hours. The same battery could take up to 10 hours if very weak. The battery state can be estimated by using the
2.Battery rating - A higher rated battery will take longer to charge than a lower rated battery under the same conditions. A battery is rated in
3.Charge rate
There are some important facts to keep in mind when charging a battery.
???When the display indicates 77% charged, the battery has been charged enough to start most vehicles and has already been charged as much as by many other battery chargers.
???When the display indicates 85% charged, the battery has already been charged at least as much as by most other battery chargers.
???The battery % shown in tester mode is an estimate based on the bat- tery voltage and the Battery Council International scale. The battery % shown in charger mode is an estimate of the relative charge in the battery
compared to the charge it should have if the charging process is allowed to complete.
???The battery % shown in tester mode can be used to estimate the relative
charge time. The lower the % shown, the longer the charge time for a given battery.
???The battery % shown in charger mode is an indication of the relative progress of the charging process. The higher the battery % displayed, the less charge time remains.
???The more a battery is discharged, the faster it absorbs charge from a
charger. That means that the battery % increases faster at the beginning of the charging process than at the end. In other words, it takes longer for the battery to absorb the last few percent of charge than the first several percent.

Read this entire manual before using your charger. The tips below serve only as a guide for specific situations.
If your vehicle won't start: You don't need to fully charge a battery to start your vehicle. If the charger won't start your vehicle using the 125A START rate,
try charging the battery using the 40A rate for 10 or 15 minutes. That should
charge the battery enough to allow the 125A START rate to start the vehicle. If the vehicle will then be operated continu- ously for an extended period (such as
a tong drive), the vehicle could charge the battery back to normal during that period. If the vehicle will only be oper- ated for a short period (short drive), the battery might need to be charged again before it could start the vehicle again.
Reviving your battery: If you only wish to charge your battery enough to oper- ate your vehicle, you don'tneed to wait for the entire charging process to be completed. When the charger displays a battery % of 77 or more (see page 13), the battery has usually been charged enough for the vehicle to start and oper- ate normally.
Completing an interrupted charge: If the charging process has been inter- rupted and restarted after the charger displays a battery % of 85 or more, the charger could go straight to Maintain Mode (see page 8). However, if the original charge was started using 40A, the charge can often be completed using the 2A rate.
A minimal amount of care can keep your battery charger working properly for years.
1.Clean the clamps each time you are finished charging. Wipe off any battery fluid that may have come in contact with the clamps to prevent corrosion.
2.Coil the input and output cords neatly when storing the charger. This will help pre- vent accidental damage to the cords and charger.
3.Occasional cleaning of the case of the charger with a soft cloth wilt keep the finish shiny.

Reset the charger by unplugging it or briefly disconnecting it or briefly disconnecting the nega-
tive battery clip. Select the desired CHARGE
RATE and CHARGE TYPE again, if neces- sary.
Charge the battery at the 40A rate for 10 to 15
minutes then crank the engine.
If the battery is in a ve-
hicle, turn the headlights on for a few minutes
to reduce the battery voltage and try charging again.
