Stable Programming Power, Battery Charging and Adjustable DC Output in One Unit
The AUTOOL EM385 supports 12 V vehicle ECU programming with a set support voltage, charges lead-acid and lithium batteries, restores long-idle lead-acid batteries and powers showroom vehicles, all selected from a 4.3-inch touchscreen. It supplies power only; the ECU work itself needs separate programming equipment.
- 9–16 V or Fixed 14 V
- Up to 150 A for ~3 Min
- LFP / NCM Charging
- 400 A Momentary Start
- 4.3-Zoll-Touchscreen
Hauptmerkmale
-
Programming Power With Live Readings
Choose Adjustable Mode for 9–16 V or Fixed Mode for 14 V and follow output voltage and current on screen throughout the procedure.
-
Lead-Acid Charging by Battery Type
Select in-car or external charging and the battery type: standard lead-acid, AGM flat plate, AGM spiral or GEL; EFB uses external charging. The display shows voltage, current, progress and completion.
-
Lithium Charging
A dedicated option for LFP (LiFePO4) and NCM batteries, with the battery removed from the vehicle.
-
Separate Adjustable Power Supply
Set both voltage and current for compatible electrical equipment, independent of programming mode.
-
Vehicle Display Mode
Maintains a float charge and raises output when battery discharge is detected, for showroom and display work.
-
Forced Start and Battery Restoration
Momentary starting support with on-screen prompts, plus a restoration treatment for discharged or long-idle lead-acid batteries; results depend on battery condition and sulfation.
-
Touch or Button Control
Use the touchscreen or the physical arrow and OK keys; brightness and interface language are adjustable.

Good to Know
Caution
- EFB charging, lithium charging and Battery Restoration all require the battery to be removed from the vehicle.
- Order the 110 V or 220 V version that matches your local power.
- Confirm that the selected mode, voltage and available output cover the full programming event before starting.
Care
- Use the unit in a dry, ventilated location with the vents clear.
- Connect clamps on clean, secure terminals with correct polarity; stop output or charging before removing them.
FAQ
Does EM385 program the ECU itself?
No. It supplies battery power support during programming; the ECU work is done with separate programming or diagnostic equipment.
How long is the maximum 150 A output available?
About 3 minutes in programming mode. At an internal temperature of 70 °C the maximum current drops to 50 A and returns once the unit cools to 50 °C.
Is the Adjustable Power Supply the same as programming mode?
No. It is a separate option under Fast Charging. Output above 1200 W for 3 minutes, or an internal temperature of 70 °C, limits current to 50 A until the unit cools below 50 °C.
