CHARGING TIMES

The size of the battery (Ah) and its depth of discharge (DOD) greatly affect its charging time. The estimated charging time shown below is based on an average discharge depth of 50% to a fully charged battery and is only for reference purposes. Actual data may differ due to battery conditions and temperature. The charger has “24H Overtime Charging Protection”.

Battery Size Ah(Amp Hour)| Approximate Time To Charge In Hours 12V 3A               12V 15A          12V 25A

OPERATING INSTRUCTIONS

Automatic Charging

1. Connect the battery clips to the battery terminals. Red clip to the positive terminal (+), and black clip to the negative terminal (-).
2. Plug the battery charger into the 120V AC outlet. Without any manual selections, the smart charger will take about 30 seconds to automatically identify and charge your battery with the optimal settings (3A & Charge to 14.1V full).

NOTE: The battery charger has prior-setting memory function. If you have already charged a battery before and have not reset new modes for a new charging, it will automatically adopt your initial settings for the new charging.

1. Connect the battery clips to the battery terminals. Red clip to the positive terminal (+), and black clip to the negative terminal (-). Plug the battery charger into the 120V AC outlet.

2. Select your desired charging rate, compatible battery and press “START” button to start charging. All the data will be shown on the LCD screen.
   Two Selectable Charging Types For Lithium Batteries
   **Lithium Battery – Option One

   Lithium Battery – Option Two**
   
   NOTE:

3. Select the Prompt Interface.

4. Wait For 3 Seconds To The Main Interface.

5. Press the “START” button to begin charging.

6. During the charging, you can press “Recondition” button to check the smart 8 charging stages. It will automatically switch back to the main interface in 5 seconds.

7. If you would like to reset the charger during the charging, first press “START” button to pause charging, reset your desired modes, and then press “START” button again to continue charging.

8. The battery power percentage on LCD display will be 100% once your battery is fully charged. Then the charger will auto-stop charging in this case.

9. Regarding a long-term connection and charging, the smart charger will auto-restart to pulse maintain battery to 100% full again when it detects voltage dropping. Auto-stop charging when it is 100% full again.

Smart 8-Stage Charging Program

1. Battery Desulfation – Adopt 15.8V pulse voltage for electrolytic removal of sulfated crystals. Automatically skip when not needed.
2. Soft Start – A slow and steady buildup of the charging process that limits the power input to protect your battery.
3. Bulk Charging – The main part of the whole charging process where the battery power will reach about 80% full.
4. Absorption – Fully charge the battery by slowly reducing the charging rate to allow your battery to absorb more power.
5. Battery Analysis – Auto-test the battery state after charging. Abnormal – enter the repair stage; Normal – turn to the next stage.
6. Battery Recondition – Restore over-discharged batteries. After repair, return to the “Bulk” stage. If it fails, an error will be reported.
7. Float Charging – Keep battery at 100% without overcharging or damages; Leave smart charger 24/7 plugged without worry.
8. Pulse Maintenance – Auto-wake up and pulse compensate to 100% full again when the voltage drops, with battery more durable.

IMPORTANT: “Desulfation”, “Recondition”, and “Engine Start/Jump Start” functions are not applicable due to the lithium/calcium battery’s characteristics, for all these three functions adopt up to 15.8V high voltage during use, which can damage lithium/calcium batteries and even cause the batteries to explode.

Winter Mode Charging

TowerTop smart battery charger, adding 0.2v more on the basis of the initial charging voltage, better boosts your battery activity and charges more thoroughly in low-temperature situations.

After connecting the battery charger to both your battery and the AC outlet, press “AMPS” button to select your desired charging rate, press “Battery Type” button to choose the compatible battery, then press “Snowflake Symbol” to select winter mode charging, and press “START” button to start charging. All the data will be shown on the LCD screen.

Battery Recondition (Not Applicable To Lithium/Calcium Batteries)

The “Recondition” function is for recovering idled or unused batteries that are deeply discharged, thus helping the battery last longer. Battery repair time up to 4 hours and “Battery Failure” will be reported if it fails to repair in 4 hours.

With the repair completed, you can directly press “START” button to start charging. Or you just wait for about 30 seconds, the battery charger will automatically switch to the charging status.

Battery Desulfation (Not Applicable To Lithium/Calcium Batteries)

The smart battery charger will identify and restore severely-sulfated battery terminals to rehabilitate the lost performance. Battery desulfation time up to 24 hours and “Battery Failure” will be reported if it fails after 24 hours. This mode will automatically skip and switch to the next stage if your battery does not need to be desulfated.

With the desulfation completed, you can directly press “START” button to start charging. Or you just wait for about 30 seconds, the battery charger will automatically switch to the charging status.

Engine Start Aid (Not Applicable To Lithium/Calcium Batteries)

Engine start aid helps in activating your car battery with insufficient power to emergently start your vehicle in 100 seconds. You need to grasp the prompt in the picture below and start your car synchronously. If you miss this interface, you may not be able to start normally.

Operation Details:

1. Select your battery type, press “Engine Start” button, the LCD screen will show and then press “START” button. LCD screen shows as follows. It switches to the 100s-count-down interface. You need to wait.

2. In the 60-second interface, it will immediately show the prompt picture below. Now you need to simultaneously start your car.
   

3. If you fail to start your car for the first time, you need to wait for the 30S interface for a second attempt. Now you also need to seize the moment and simultaneously start your car.
   

4. If you fail to start your car for the second time, you need to wait until the count-down is over and show the prompt picture again for a third attempt.

If you fail to start your car in the three attempts above, the LCD display will show as follows. This is the whole working cycle for the “Engine Start” function. In this case, if you still want to have a try again, press “Engine Start” and “START” buttons again, then repeat previous steps.
