Three-stage battery charging：
STAGE 1 – Bulk Charge: Delivers maximum charging amperage to "wake
up" any serviceable 12V battery and allows for quick engine starting. When
battery reaches a maximum safe predetermined voltage, the charger will
automatically move into Stage 2 of the charging process.
STAGE 2 – Absorption Charge: Maintains the maximum possible charge at
a constant, safe, predetermined voltage. During this phase, the charging
voltage remains constant, while the actual charging current is reduced to
allow for the maximum proper internal chemical energy transfer. At the end
of Stage 2, the charger will automatically move to Stage 3.
STAGE 3 – Float Charge: Voltage is automatically maintained and reduced
to a predetermined level while current is adjusted for a safe, effective battery
charge.
The Automatic Float Charge feature is ideal for maintaining a battery. It
automatically tops off battery as needed, to keep battery fully charged all the
time.

5. OPERATING INSTRUCTIONS
Using this battery charger is extremely simple. The built-in microprocessor
was designed to seamlessly work with all types of 12 V lead-acid batteries
so you don’t need to select whether your battery is conventional, low
maintenance, maintenance-free, deep cycle, gel cell or AGM.
First, prepare your battery and make output cable and AC power
connections following the precautions and instructions described in
“PREPARING TO CHARGE.” Once the AC cord is plugged in, the charger
will begin charging. The charger will then do everything else automatically.
The following section called “CHARGER FEATURES” will provide greater
detail about how your charger operates and some of its features.
6. CHARGER FEATURES
CONNECTION METHODS
This charger comes with 2 run connect charging leads for extra versatility –
standard clamps and ring terminals. The battery may be charged using any
of the two connection options.
WARNING: you can only select one charging method for charging at one
time.
2A CHARGE RATE
This charger is recommended for charging small batteries such as those
used in motorcycles, ATVs, snowmobiles, personal watercraft, lawn tractors
and golf cars. It is also suitable to maintain larger batteries such as those
used in automobile, marine and farm tractors.
OPTIONAL CONNECTION METHODS
This charger comes with 3 quick connect charging leads for extra versatility
– standard clamps, ring terminals and 12 V accessory plug. The battery
may be charged using any of these three connection options.
CHARGING INDICATOR
A yellow LED indicates that the battery is being charged.

10

AUTOMATIC SHUT OFF
The battery charger is designed to automatically shut off once battery
charging is complete to prevent overcharging. When charging is complete,
the CHARGED/MAINTAINING LED will illuminate and the charger has
switched to Maintenance mode.
MAINTENANCE MODE
Once charging is complete, the charger will automatically go into
Maintenance mode (also known as float mode monitoring). In this mode, the
charger keeps the battery fully charged by delivering a small amount of
current, when necessary, to keep the battery at peak charge.
REVERSE POLARITY PROTECTION
If the cables are incorrectly connected to the battery, the Reverse Polarity
indicator will illuminate. Note, the charger will not begin charging if the
Reverse Polarity indicator is lit.
OVERHEAT PROTECTION
The charger is designed to shut itself off if overheating is detected. Once
the charger cools down, it will resume charging automatically.
7. BATTERY CHARGING TIMES
The built-in intelligent microprocessor will continuously monitor and adjust
the charger to provide a fast, safe and efficient charge. Note that battery
charge times will vary depending on several factors including:
1. Battery State – If a battery has been only slightly discharged, it can be
charged in less than a few hours. This same battery could take up to 10
hours if very discharged.
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
ampere-hours (Ah), reserve capacity (RC) and cold-cranking amps
(CCA).
3. Charge Rate – The charge rate is measured in amps. A battery
charged at a lower rate will take longer than a battery charged at a
higher rate. However, smaller batteries can be easily damaged by
charging at a rate which is too high for the capacity of the battery.

11

4. Temperature – Cold temperature will affect a batteries ability to accept
a charge. Charging in cold temperatures will increase the amount of
time required to charge a battery.
8. MAINTENANCE AND CARE
Clean cords and clamps each time you are finished using the charger.
Wipe off any battery fluid or debris that might have come in contact with
the clamps to prevent corrosion.
Store the power and output cable neatly to prevent damage.
Occasional cleaning of the battery charger case with a soft cloth will
help protect the finish.
Always unplug the charger when not in use.
Keep the charger stored in a cool, dry place.
