Functions

Multiple Charging Modes
In order to meet the needs of charging various 12V devices, T120A supports multiple charging modes: SUPPLY, Lead-Acid, LiFePO4, and Custom. The explanations are given below:

output current is up to the load to be charged (but won’t exceed the maximum current set by the user). The maximum output power is 1700W.

This mode is suitable for two scenarios: & . (The battery clamp voltage is greater than 3V or close to 0V.)During charging, the charging voltage and current can be modified.
Press on T120A. Then press or to choose or . After that, press . Then press or to modify the voltage. After that, press . Then press or to modify the current. After that, press . (Charging will be based on the new voltage and current.)
LeadAcid| NORM| 14.2V| This mode follows a stepwise charging algorithmthat delivers constant voltage or current atdifferent steps. It can be used to charge 12Vlead-acid batteries, including WET, GEL, MF,CAL, EFB, and AGM.
| AGM| 14.4V|
After setting up the battery capacity, you can
choose to charge the battery at the rate of
0.1C or 0.2C.
0.1C or 0.2C means the charging current is 10%
or 20% of the battery capacity. For example, if a
100Ah battery is charged at the rate of 0.1C, the
charging current will be 10A; if it is charged at
the rate of 0.2C, the charging current will be 20A.
Charging a battery at the rate of 0.1C is slow. It
can extend battery life and reduce the risk of
battery damage, but it takes longer to fully
charge the battery. Charging it at the rate of 0.2C
is faster and can still protect it from overheating
or even damage.
LiFePO4| 14.6V| This mode follows a stepwise charging algorithm that delivers constant voltage or current at different steps. It can be used to charge 12V LiFePO4 batteries.

After setting up the battery capacity, you can choose to charge the battery at the rate of 0.1C or 0.2C.
Custom| Defined by the user| The user can choose from SUPPLY, Lead Acid, and LiFePO4, and then define the charging voltage and current.

After setting, this mode will be auto-saved for quick use later. For example, suppose you choose Lead Acid and set the voltage and current to be 14.5V and 30A respectively. After the setting, T120A will charge the Lead Acid battery by following a stepwise charging algorithm. When the battery is fully charged, the voltage will be 14.5V.

Smart Charging Algorithm

The explanations are given below:

1. DIAGNOSIS: It checks the battery’s initial condition including voltage, state-of-charge, and health, to determine if the battery is stable before charging.
2. DESULPHATION: It uses voltage or high-frequency pulses to break down the sulfates that have built up over time in the aging battery to optimize life and performance. (only for the Lead-Acid mode)
3. PRE-CHARGE: It starts the charging process with a low stable current that gradually increases until the battery capacity returns 25%. This reduces the stress put on batteries by sudden surges.
4. SOFT START: It provides a medium stable current until the battery capacity returns 50%.
5. BULK CHARGE: It begins the bulk charging process based on the condition of the battery until the battery capacity returns 80%.
6. ABSORPTION: It brings the charge level to 100% by delivering small amounts of current to provide a safe, efficient charge. This limits battery gas emission and prolongs life.
7. ANALYSIS: It monitors whether the battery voltage falls below its target threshold. If yes, the charger will enter the Recondition mode.
8. RECONDITION: It checks the battery status, and then recovers small currents to improve the capacity. (only for the Lead-Acid mode)
9. MAINTENANCE: It checks the battery status and brings the charge level back to 100%. Then the ANALYSIS, RECONDITION, and MAINTENANCE will form into a charge cycle to keep the battery at full charge. The battery charger can be safely left connected indefinitely without the risk of overcharging. (only for the Lead-Acid mode)

Multiple Protection Mechanisms
T120A is designed with multiple protection mechanisms to ensure safety for both the device and batteries, including over-voltage protection, low-voltage protection, over-load protection, over-temperature protection, short-circuit protection, reverse polarity protection, and bad-battery protection.

Charging

Note: Before charging a battery, please refer to the manual by its manufacturer to determine its technical specifications.

1. Take the clamp cable. Connect one end to the Output Port on the back of T120A, and connect the other end (the two clamps) to the battery terminals. The positive clamp (red) goes with the positive terminal, and the negative clamp (black) goes with the negative terminal.

2. On the homepage, press  or to choose the “Work Mode” option, and then press to go to the charging mode page. Press  or to choose the charging mode that you need and then press . Then set up the charging parameters.
   Please refer to the technical specifications of the battery to be charged.
   For more information, please see 4.2.1 Multiple Charging Modes.

3. Press to start charging.
   When the battery is fully charged, T120A will stop charging automatically.
   During charging, if you press , it will stop charging. If you press it again, it will resume charging.
   During charging, if you press and hold for 3 seconds, it will stop charging and go back to the homepage.

Using the Data Port
T120A comes with a built-in button battery which saves the dates and charging reports.

After charging, you can use the USB-A to USB-B cable to connect T120A to a PC (Windows). Then you can export charging reports or upgrade the firmware via a PC-based software.

To get the PC-based software and the firmware upgrade package, please go to the link (https://[www.topdon.com](http://www.topdon.com)/pages/pro- down?fuzzy=TORNADO120000) for download or contact support@topdon.com.

Power-off
After charging, you can press the Power Button on the back of T120A to shut it down. (T120A will shut down in 5~10 seconds.)

TECHNICAL SPECIFICATIONS

Note: The manufacturer may update the product, and thus its specifications may change. We recommend that you read the user manual carefully or consult the manufacturer to understand its actual parameters and performance before you buy it.

FAQ

Q: How do I choose the charging current?

A: The optimal charging current is up to the battery capacity. We recommend that the current be no greater than 20% of the battery capacity. For example, for a 100Ah battery, the charging current should not be greater than 20A.

Q: Will T120A automatically stop charging a battery after it is fully

charged?

A: Yes. T120A follows a smart stepwise charging algorithm. When the battery is fully charged, T120A will automatically stop charging it. There is no risk of overcharging. If you still keep the battery connected after it is fully charged, the charger will continuously monitor its status and will automatically resume charging when the battery voltage falls below the threshold.

Q: How come some batteries cannot get charged properly?

A: In general, a 12V battery with a voltage below 8.5V may have been damaged and thus cannot get charged properly. You can try the SUPPLY mode for charging the battery
