Before You Order And Use

Before You Order And Use

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.

    I have an EM365, which I bought three years ago. It’s time to change to a new version. The EM385 is beyond my expectation. It’s perfect. In addition to the increased functions, the quality is also very good. Worth buying!!!

  8. Benjamin Kucsera

    I’ve been using it for a while now and I can genuinely say¡ªit’s a good power inverter. It supports both Lithium Iron Phosphate and Nickel Cobalt Manganese Lithium batteries, which is a huge plus for me. I had trouble with compatibility on older chargers, but this one just works flawlessly.

    What I love most is the adjustable output. Being able to fine-tune the voltage and current gives me so much more control, and the multi-stage smart charging mode ensures my batteries are charged efficiently without overheating or overcharging.

    The Vehicle Display Mode is another great feature¡ªit keeps power running without interruptions and even auto-restarts if power is lost. That¡¯s been incredibly helpful when powering diagnostic tools in the garage.

    The 4.3-inch touchscreen is clear and responsive, and the adjustable brightness is a thoughtful touch¡ªespecially useful in different lighting environments. Also, the build quality is top-notch. The 2-meter pure copper cable feels premium and reliable, and the IP21S protection rating gives me peace of mind when using it in various settings.

    Overall, this is one of the smartest and most well-built chargers I¡¯ve used. Highly recommend it to anyone who values safety, flexibility, and quality in their tools!

    I bought it because it supports lithium batteries! Multi-stage smart charging mode allows you to charge optimally.
    It makes me happy that it can provide me with a stable power supply when I do ECU programming.
    I will continue to see how it works. And come back with feedback on the results
