This manual will explain how t o use t he charger safely and effectively. Please read and follow t hese
instruct ions and precautions carefully.
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS.
Read all instructions, warning, and cautions printed on t he bat tery charger, bat tery and vehicle or
equipment using bat tery.
DO NOT expose charger t o rain or snow.
Use of an at tachment not recommended or sold by t he batt ery charger manufacturer may result in a
risk of fire, electric shock, or injury t o persons.
To reduce risk of damage to electric plug and cord, pull by plug rather than cord when disconnecting
charger.
An extension cord should not be used unless absolut ely necesssary.
Use of an improper ext ension cord could result in a risk of fire and electric shock. If an extention cord
must be used, make sure:
The pins on plug of ext ension cord are the same number, size, and shape as those of plug on charger.
The extension cord is properly wired and in good elect rical condit ion.
The wire size is large enough for t he AC ampere rat ing of t he charger, as specified in t he chart on
the following page.
DO NOT operat e charger with damaged cord or plug—replace the cord or plug immediat ely.
DO NOT operat e charger if it has received a sharp blow, been dropped, or ot herwise damaged in any
way—take it to a qualified serviceman.
DO NOT disassemble the charger. Take it t o a qualified service professional if service or repair is
required. Incorrect assembly may result in fire or elect ric shock.
To reduce risk of elect ric shock, unplug charger from outlet before at tempt ing any maintenance or
cleaning. Turning off controls will not reduce t his risk.
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS. BATTERIES GENERATE EXPLOSIVE
GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE
THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.
To reduce risk of bat tery explosion, follow t hese instructions and t hose published by batt ery
manufact urer and manufact urer of any equipment you int end to use in the vicinit y of t he batt ery.
Review cautionary markings on t hese product s and on engine.
Consider having someone close by to come to your aid when you work near a lead-acid bat tery.
Have plent y of fresh water and soap nearby in case batt ery acid contact s skin, clothing, or eyes.
Wear complete eye protect ion and clot hing prot ection. Avoid touching eyes while working near
batt ery.
If batt ery acid cont acts skin or clothing, wash immediately with soap and wat er. If acid ent ers eye,
immediat ely flood eye with running cold wat er for at least 10 minutes and get medical att ention
immmediately.
NEVER smoke or allow a spark or flame in vicinit y of bat tery or engine.
Remove personal met al items such as rings, bracelets, necklaces, and watches when working with a
lead-acid bat tery. A lead-acid batt ery can produce a short-circuit current high enough to weld a ring
or the like t o met al, causing a severe burn.
Use charger for charging a LEAD-ACID batt ery only. It is not intended to supply power to a low volt age
electrical system ot her than in a st arter-mot or applicat ion. Do not use bat tery charger for charging
dry-cell bat teries that are commonly used wit h home appliances. These batt eries may burst and cause
injury to persons and damage t o property.
NEVER charge a frozen batt ery.

UNDERSTANDING FACTORS THAT AFFECT CHARGING TIME
CHARGING YOUR BATTERY
1. Connect t he charger clamps to t he batt ery (following the steps outlined in “ Connect ing Your
Batt ery” ).
2. Plug t he charger AC plug into an electrical outlet.
NOTE: If a fault or error is det ect ed, the LED will illuminat e (see Charge Status Indicat ors).
3. Press t he butt on to select batt ery t ype.
4. Press the MODE butt on to select a charging program.
NOTE: If no selection is made within 5-seconds, the charger will default to t he last selection in
memory and aut omat ically begin charging.
5. Your bat tery is fully charged when the indicat or turns solid green and t he display reads
“ 100% ” .
6. St op charging at any time by disconnect ing t he charger AC plug from the elect rical outlet .
Examples of Battery Sizes in Common Applications
Small (10–25 Ah) Motorcycle, scooter, ATV, personal wat ercraft, snowmobile.
Medium (30–50 Ah) Compact car, mid-size sedan, compact SUV, riding mower, UTV.
Large (60–100 Ah) Full-size car, large SUV, t ruck, boat, RV, farm t ractor.
Ext ra large (100 Ah+) Large marine, tractor t railer, bus, multiple batteries connected in a bank.
For reference only. Please check t he specificat ions listed on your bat t ery or consult with t he bat tery
manufact urer.
12V
Using Reconditioning Mode
If a lead-acid battery is left sit ting in a low st ate of charge, or is deeply discharged, or is never given
the opportunit y to fully charge, it can suffer capacity loss due to sulphat ion and/ or st ratificat ion. Such
a batt ery can appear to have a normal open circuit volt age and yet it will have a not iceable drop in
performance. Using Recondit ioning mode may help t o reverse t he affect s of sulphat ion and strat ifica-
tion, rest oring lost batt ery capacity.
To maximize batt ery life and performance, Recondition your bat tery once per year or after deep
discharges. For best results, take t he batt ery t hrough a normal full charge cycle before using this
mode. A Reconditioning charge can take up t o 4 hours to complete.
CAUTION: USE THIS MODE WITH CARE. RECONDITIONING USES A HIGH CHARGING VOLTAGE AND MAY
CAUSE WATER LOSS IN THE BATTERY. IT IS BEST SUITED FOR WET (FLOODED) BATTERIES WITH REMOV-
ABLE VENT CAPS WHICH ALLOWS FOR WATER LEVELS TO BE TOPPED UP. RECONDITIONING IS NOT
RECOMMENDED FOR AGM OR GEL BATTERIES. TO MINIMUM RISK OF HIGH VOLTAGE TO SENSITIVE
ELECTRONICS, DISCONNECT THE BATTERY FROM THE VEHICLE (OR ANY OTHER EQUIPMENT) WHEN USING
THIS MODE.
UNDERSTANDING FACTORS THAT AFFECT CHARGING TIME
The time it t akes to fully recharge a bat tery depends on several fact ors including:
1. Battery Depth of Discharge
The greater t he depth of discharge, the longer it will t ake to fully charge a batt ery. For example, a
batt ery discharged t o a level of 50% will t ake about t wice as long t o fully charge t han a bat tery
discharged only 25% .
2. Battery Size
If charged at t he same current , a larger (higher capacit y) bat tery will require more time to fully
charge than a smaller (lower capacit y) bat tery. This difference can be overcome by charging larger
batt eries at a higher current .
3. Battery Age and Condition
As a bat tery ages, its internal resist ance willl increase, impact ing it s abilit y t o accept current. This
effect is particularly noticeable in batt eries that have not been well-maintained over t heir life.
4. Battery Type
Some batt ery chemist ries, such as AGM and gel, have lower internal resistance which means they can
accept charge bet ter without generating damaging heat . Such batt eries can charge up t o 2 t imes
faster t han t raditional wet bat tery t ypes.

MAINTENANCE AND CARE
UNDERSTANDING THE MULTI-STAGE CHARGING PROCESS
5. Charge Rate
The charge rate is measured in amperes (A). A batt ery charged at a lower rat e will take longer t o fully
charge t han a bat tery charged at a higher rate. This does not mean t hat one should always charge a
batt ery at t he highest ampere available as this can cause overheat ing and premat ure batt ery failure.
A batt ery should be charged at a rate appropriate for it s size—a good, safe rule of t humb is about
1/ 10 it ’s Amp-hour capacit y (e.g., 100 Ah batt ery x1/ 10=10 A).
6. Cold Temperature
Cold t emperat ures slow down the chemical react ion that takes place inside a bat tery when it is
charging. Charging a bat tery at a cold temperat ure can great ly increase t he amount of t ime required
to charge the batt ery. Ideal charging temperature is between 10 t o 25º C (50 to 77º F).
* *
* *
STAGE 1 DESULPHATION*
Pulses of voltage and current help recover sulphat ed or deeply discharged bat teries.
STAGE 2 SOFT START*
Gently int roduces current to condit ion deeply discharged batt eries and prevent overheat ing that could
damage t he batt ery.
STAGE 3 BULK
Charging wit h maximum current to bring the batt ery t o about 80% capacit y.
STAGE 4 ABSORPTION
Charging wit h constant voltage while reducing current to safely bring the bat tery t o 100% capacity.
This stage is key t o maximizing bat tery performance and bat tery life.
STAGE 5 ANALYZE
