INTRODUCTION
This MotoMaster Nautilus Battery Charger features advanced technology that makes battery charging
faster, easier, and safer while helping to maximize the performance and life of your batteries.
This battery charger is designed for use on all types of 12-volt lead-acid batteries including Wet
(flooded), Maintenance-free (MF), Calcium (Ca), Enhanced Flooded (EFB), Absorbed Glass Mat (AGM),
and Gel. It is suitable for charging batteries rated from 10 to 300 Amp-hours and maintaining
batteries from 10 to 500 Amp-hours.
This manual will explain how to use the charger safely and effectively. Please read and follow these
instructions and precautions carefully.
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS.
Read all instructions, warning, and cautions printed on the battery charger, battery and vehicle or
equipment using battery.
DO NOT expose charger to rain or snow.
Use of an attachment not recommended or sold by the battery charger manufacturer may result in a
risk of fire, electric shock, or injury to 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 absolutely necesssary.
Use of an improper extension 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 extension cord are the same number, size, and shape as those of plug on charger.
The extension cord is properly wired and in good electrical condition.
The wire size is large enough for the AC ampere rating of the charger, as specified in the chart on
the following page.
DO NOT operate charger with damaged cord or plug—replace the cord or plug immediately.
DO NOT operate charger if it has received a sharp blow, been dropped, or otherwise damaged in any
way—take it to a qualified serviceman.
DO NOT disassemble the charger. Take it to a qualified service professional if service or repair is
required. Incorrect assembly may result in fire or electric shock.
To reduce risk of electric shock, unplug charger from outlet before attempting any maintenance or
cleaning. Turning off controls will not reduce this 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 battery explosion, follow these instructions and those published by battery
manufacturer and manufacturer of any equipment you intend to use in the vicinity of the battery.
Review cautionary markings on these products and on engine.
Consider having someone close by to come to your aid when you work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
Wear complete eye protection and clothing protection. Avoid touching eyes while working near
battery.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid enters eye,
immediately flood eye with running cold water for at least 10 minutes and get medical attention
immmediately.
NEVER smoke or allow a spark or flame in vicinity of battery or engine.
Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring
or the like to metal, causing a severe burn.
Use charger for charging a LEAD-ACID battery only. It is not intended to supply power to a low voltage
electrical system other than in a starter-motor application. Do not use battery charger for charging
dry-cell batteries that are commonly used with home appliances. These batteries may burst and cause
injury to persons and damage to property.
NEVER charge a frozen battery.

A. Digital Display
During charging, the digital display will alternate between Volts (V), Amperage (A) and Battery State of
Charge (%). It can also display Fault Codes if a charging error is detected.
Volts—Actual charging voltage will be displayed. Charging voltage can reach up to 14.4 V—this is normal
and required to effectively charge a 12-volt battery.
Amps—Actual charging amperage will be displayed. While you may select 2 A, 8 A, or 15 A charge
modes, these are maximum currents and the battery charger will reduce actual current delivered to the
battery based on feedback from the battery and other factors.
Stage of Charge—The approximate battery state of charge is displayed. A reading of “LO” indicates
that the battery is below 50% state of charge. Above 50%, the percentage will display in 10%
increments between 60 to 90% capacity. Once the battery is fullly charged, the display will read
“100%”.
NOTE: About 30 minutes after reaching full charge, the battery charger will enter a power-saving mode
and the digital display will turn off.
Fault Codes—The charger will continuously monitor charge progress and collect feedback from the
battery during charging. In the event an abnormal condition is detected, charging will stop and a fault
code (e.g., ”F01”) may be displayed. (See ”Troubleshooting/Fault Codes” for possible causes and
solutions.)
NOTE: A fault condition will also be indicated by the LED illuminating.

UNDERSTANDING FACTORS THAT AFFECT CHARGING TIME
CHARGING YOUR BATTERY
1. Connect the charger clamps to the battery (following the steps outlined in “Connecting Your
Battery”).
2. Plug the charger AC plug into an electrical outlet.
NOTE: If a fault or error is detected, the LED will illuminate (see Charge Status Indicators).
3. Press the button to select battery type.
4. Press the MODE button to select a charging program.
NOTE: If no selection is made within 5-seconds, the charger will default to the last selection in

Using Reconditioning Mode
If a lead-acid battery is left sitting in a low state of charge, or is deeply discharged, or is never given
the opportunity to fully charge, it can suffer capacity loss due to sulphation and/or stratification. Such
a battery can appear to have a normal open circuit voltage and yet it will have a noticeable drop in
performance. Using Reconditioning mode may help to reverse the affects of sulphation and stratifica-
tion, restoring lost battery capacity.
To maximize battery life and performance, Recondition your battery once per year or after deep
discharges. For best results, take the battery through a normal full charge cycle before using this
mode. A Reconditioning charge can take up to 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 takes to fully recharge a battery depends on several factors including:
1. Battery Depth of Discharge
The greater the depth of discharge, the longer it will take to fully charge a battery. For example, a
battery discharged to a level of 50% will take about twice as long to fully charge than a battery
discharged only 25%.
2. Battery Size
If charged at the same current, a larger (higher capacity) battery will require more time to fully
charge than a smaller (lower capacity) battery. This difference can be overcome by charging larger
batteries at a higher current.
3. Battery Age and Condition
As a battery ages, its internal resistance willl increase, impacting its ability to accept current. This
effect is particularly noticeable in batteries that have not been well-maintained over their life.
4. Battery Type
Some battery chemistries, such as AGM and gel, have lower internal resistance which means they can
accept charge better without generating damaging heat. Such batteries can charge up to 2 times
faster than traditional wet battery types.

MAINTENANCE AND CARE
UNDERSTANDING THE MULTI-STAGE CHARGING PROCESS
5. Charge Rate
The charge rate is measured in amperes (A). A battery charged at a lower rate will take longer to fully
charge than a battery charged at a higher rate. This does not mean that one should always charge a
battery at the highest ampere available as this can cause overheating and premature battery failure.
A battery should be charged at a rate appropriate for its size—a good, safe rule of thumb is about
1/10 it’s Amp-hour capacity (e.g., 100 Ah battery x1/10=10 A).
6. Cold Temperature
Cold temperatures slow down the chemical reaction that takes place inside a battery when it is
charging. Charging a battery at a cold temperature can greatly increase the amount of time required
to charge the battery. Ideal charging temperature is between 10 to 25ºC (50 to 77ºF).

STAGE 1 DESULPHATION*
Pulses of voltage and current help recover sulphated or deeply discharged batteries.
STAGE 2 SOFT START*
Gently introduces current to condition deeply discharged batteries and prevent overheating that could
damage the battery.
STAGE 3 BULK
Charging with maximum current to bring the battery to about 80% capacity.
STAGE 4 ABSORPTION
Charging with constant voltage while reducing current to safely bring the battery to 100% capacity.
This stage is key to maximizing battery performance and battery life.
STAGE 5 ANALYZE
Tests if battery is holding charge.
STAGE 6 MAINTENANCE
