NEO TOOLS 11-890 Automatic Battery Charger 2A/35W for 12V Lead-Acid, AGM, Gel Batteries 4-60Ah

Unlike bulky workshop chargers, the NEO TOOLS 11-890 brings intelligent 7-stage charging to a compact, fanless unit that you can use anywhere. It automatically diagnoses battery condition, adjusts voltage and current, and then switches to float mode once the battery is full — so you can leave it connected overnight without risk of overcharging. Whether you maintain a car, motorcycle, scooter, ATV, or lawn mower, this charger handles 12V lead-acid (wet), AGM, and gel batteries from 4 to 60 Ah with a steady 2 A current and 35 W of power.

Highlights

• Microprocessor-controlled automatic charging: 7 stages from desulfation to float
• Works with 12V wet (lead-acid), AGM, and gel batteries — 4–60 Ah recommended capacity
• LED indicators for power, charging, fully charged, and error status
• Comprehensive protection: overcharge, short-circuit, reverse polarity, overheat, and spark-proof
• Fanless, natural convection cooling — silent operation and no moving parts
• Durable ABS housing with IP20 rating for indoor use
• 1.5 m input and output cables with alligator clamps for secure connection

In daily use

The 11-890 plugs into any standard 220–240 V AC outlet and delivers a controlled DC charge to your battery. Its automatic voltage detection prevents mistakes, and the reverse polarity protection stops current if the clamps are connected incorrectly. The clear LED panel tells you at a glance whether the battery is charging, fully charged, or if there is a fault. Because it is fanless, there is no noise and no dust build-up, making it ideal for home garages or enclosed spaces.
