NEO TOOLS 11-891-1 Cargador de batería automático 4A/70W para baterías de plomo-ácido, AGM y GEL de 6V/12V (3-120Ah)

Most chargers force you to choose between battery types—this one doesn’t. The NEO TOOLS 11-891-1 automatically detects 6V or 12V systems and adjusts its charge curve for wet, AGM, or GEL batteries, delivering a precise 4A/70W charge without manual switches. Its IP65-rated housing shrugs off dust and splashes, making it safe for workshop floors or outdoor use.

Highlights

• Automatic voltage detection: 6V or 12V DC output, no switches to set
• Supports lead-acid (wet), AGM, and GEL batteries from 3Ah to 120Ah
• Multi-stage charging (7 stages) for optimal battery health and longevity
• Built-in protection: overcharge, short circuit, reverse polarity, overheat, and spark proof
• IP65 dustproof and splash-proof ABS housing for rugged environments
• Fanless passive cooling – silent operation, no moving parts to fail
• LED indicators for clear charging status at a glance
• 1.5m input and output cables with crocodile clips for easy connection

In daily use

Connect the clamps to your battery, plug it in, and the charger takes over. The automatic detection means you won’t accidentally overcharge a small motorcycle battery or undercharge a large car battery. The LED indicators show progress, and once the battery is full, the charger switches to maintenance mode. Because it’s fanless, you can leave it running overnight without noise. The long cables let you position the unit safely away from the battery, and the spark-proof design adds an extra layer of safety when connecting in confined engine bays.
