The AUTOOL EM385 is a high-performance 3-in-1 power inverter supply for ECU programming, fast battery charging, jump-starting, battery repair, showroom power support, and workshop electrical service. It provides adjustable programming power from 9-16V to keep voltage stable during ECU programming and decoding, supports both lead-acid and selected lithium batteries, and uses multi-stage smart charging with automatic stop protection. With 400A emergency start support for engines below 3.0L, a 4.3-inch touch screen, IP21S protection level, nine safety protections, pure copper output cables, and 3-year warranty support, EM385 is built for efficient and safe workshop use on vehicles such as BMW, Audi, Mercedes-Benz, and more.
EFB charging and repair mode are important safety points. Keep these warnings visible before using EM385 charging or battery restoration functions.
EFB Battery Usage Instructions
EFB batteries contain liquid electrolyte that is prone to boiling, and overheating during charging may cause fire or explosion. For safety reasons, In-car Charging mode does not include an EFB option. If your battery is an EFB type, remove it from the vehicle and select External Charging mode.
Repair Mode Warning
Repair mode can be used for batteries deeply discharged for an extended period, such as batteries affected by sulfuric acid buildup. However, repair mode may damage vehicle electronics. Always remove the battery from the vehicle before using repair mode. Repair success depends on battery vulcanization level and may cause fluid loss or internal drying.

Before You Order And Use
Before You Order And Use
EM385 supports common workshop battery service needs and adds lithium battery compatibility compared with EM355 and EM365. Always confirm the battery type before selecting charging or repair mode.
Lead-Acid / GEL / AGM / EFB
Supports traditional lead-acid batteries, GEL batteries, EFB batteries, and AGM flat plate batteries for common 12V vehicle service.
LiFePO₄
Supports lithium iron phosphate battery charging and maintenance, making EM385 suitable for broader modern battery service.
NCM Lithium
Supports nickel cobalt manganese lithium battery service, a capability not available on EM355 and EM365.
EFB Caution
EFB batteries must be removed from the vehicle and charged in External Charging mode to reduce overheating, boiling, fire, or explosion risk.
