How To Use

To change and select mode:
There is a 3 to 5 seconds interval to change the mode after you connect the battery clamps to the battery only when the battery is fully charged. Due to safety features, we designed to lock the mode button once the battery is fully charged to keep the battery in maintenance mode. Please press the “Mode” button for under 5 seconds when it is connected to the battery. You can always change the mode during the charging process for a battery that is partially charged.

LED power indicator light:
The Charger will continuously monitor the battery voltage to determine if a maintenance charge should be initiated. If the terminal voltage falls below 6.4V (6V) and 12.8V (12V), the charger will start the maintenance cycle until the voltage reaches 7.2V (6V) and 14.4V (12V) and then it discontinues the charge cycle. The cycle between trickle and maintenance is repeated indefinitely to keep the battery at full charge, without overcharging. The battery charger can be left connected indefinitely. All 4 LEDs lights (25%, 50%, 75%, 100%) will be illuminated constantly to maintain the battery for all seasons.

Standby:
In Standby mode, the charger is not charging or providing any power to the battery. Once the battery clamps is removed from the battery, standby mode will be activated to avoid electrical shock. Energy Save is activated during this mode, drawing microscopic power from the electrical outlet. When in Standby, the green Standby LED will illuminate.

Error :
light will illuminate when an error condition or reverse polarity is present .

Connecting to the Battery with Battery Clamps

Do not connect the AC power plug until all other connections are made. Identify the correct polarity of the battery terminals on the battery. The positive battery terminal is typically marked by these letters or symbols (POS, P,+). The negative battery terminal is typically marked by these letters or symbols (NEG, N,-). Do not make any connections to the carburetor, fuel lines, or thin, sheet metal parts. The below instructions are for a negative ground system (most common). If your vehicle is a positive ground system (very uncommon), follow the below instructions in reverse order.

1. Connect the positive (red) battery clamp or eyelet terminal connector to the positive (POS, P,+) battery terminal.
2. Connect the negative (black) battery clamp or eyelet terminal connector to the negative (NEG, N,-) battery terminal or vehicle chassis.
3. Connect the battery charger to a suitable electrical outlet. Do not face the battery when making this connection.
4. When disconnecting the battery charger, disconnect in the reverse sequence, removing the negative first (or positive first for positive ground systems).

Quick-Connect O-Ring Terminal

The O-ring connectors are permanently attached to the battery, providing easy access to quickly connect the charger to your battery. This application is appropriate for motorcycles, lawn tractors, ATVs, and snowmobiles.

1. To permanently attach to a battery, loosen and remove each nut from the bolt at the battery terminal.
2. Connect the red (+) POSITIVE connector ring to the (+) POSITIVE battery terminal.
3. Connect the black (-) NEGATIVE connector ring to the (-) NEGATIVE battery terminal.
4. Replace and tighten the nuts to secure them.
5. Connect the cable to the end of the charger output cord. Take care to keep the wires and plug away from metal and moving parts.
6. Plug the charger power cord into a grounded electrical wall outlet.

8-Stage Charging Steps

• Step 1: Diagnostics
  Checks the battery voltage to make sure battery connections are good and the battery is in a stable condition before beginning the charging process.

• Step 2: Recovery
  Initializes the Recovery process, if needed, the charger will perform deeply discharged or sulfated (desolations) batteries by pulsing small amounts of current.

• Step 3: Soft Start
  Begins bulk charging process with a gentle (soft) charge.

• Step 4-5: Bulk
  The bulk charging process continues using both a High Rate or Medium Rate charge so that the battery will return 80% capacity, and it will indicate 25%, 50%, and 75% charging levels.

• Step 6: Absorption
  It brings the charging level to 90%, the battery charger will deliver small amounts of current to provide a safe, efficient charge and limit battery gassing.

• Step 7: Trickle
  The battery is fully charged and ready to use, as indicated by the 100% Charge LED illuminate solid Green. In this step, the battery charger will only deliver enough current to keep the battery in full charge. If the battery sends a signal to the charger that requires more current, then the battery charger will switch to the maintenance stage.

• Step 8: Maintenance
  The Charger will continuously monitor the battery voltage to determine if a maintenance charge should be initiated. If the terminal voltage falls below 6.4V (6V) and 12.8V (12V), the charger will start the maintenance cycle until the voltage reaches 7.2V (6V) and 14.4V (12V) and then it discontinues the charge cycle. The cycle between trickle and maintenance is repeated indefinitely to keep the battery at full charge, without overcharging. The battery charger can be left connected indefinitely.

FAQ

How to know if the battery charger is working?
After the battery clamps / O-ring is hooked up to the battery, the LED power indicator light will start blinking or solid, and it depends on the juice of the battery.

what are some scenarios that might cause it to malfunction?
Your car battery may be too old and the acid in the battery that is never fully recharged can also suffer from acid stratification.

Can you hook up the battery clamps directly to the battery terminal without removing the battery?
Yes, you may simply hook up the battery clamps or O-ring directly to the battery. Friendly reminder: some newer vehicles have a start/stop engine feature, and they have two batteries, (main battery and auxiliary battery), we suggest removing the battery terminals before placing the battery charger on the battery.

Is it safe to leave the battery charger maintainer 24/7?
Yes. Please refer to Step 7 Trickle charge and Step 8 Maintenance.

Can this battery charger use to charge the generator battery?
Yes, Battery Compatibilities Works with all types of 6-volt and 12-volt lead- acid batteries.

Can you charge a dead battery or the voltage is too low?
No, if your battery is low in voltage, and your car wouldn’t start at all, you may need to jump-start the battery first then use this battery charger to recharge the battery. You would need a 400 amp jump start to jump the battery first in order to recharge the battery. The 3.6-amp battery charger is not enough amp to charge up the battery.

The battery charger keeps changing from error light, standby, and 25% charging light. Do I have a bad battery?
Yes, your battery voltage is too low to detect by the charger, please use jumper cables or a portable jump starter to jump-start the battery, then you can use this battery charger to keep the battery charged.

Here are some bad battery symptoms:

• During an engine crank, you won’t hear the engine turning over
• You don’t see the instrument panel or dashboard lights turn on
• It’s hard to start your car on a cold morning
• Flickering or non-functioning headlights
• The dome light won’t turn on
• Your car displays the battery symbol hinting at your battery troubles
