The CTEK US 0.8 (Part No. 56-865) is the smallest and most efficient 12V charger in CTEK’s range, purpose-built for maintaining and charging smaller batteries used in motorcycles, jet skis, ATVs, snowmobiles, and lawnmowers. Combining advanced microprocessor-controlled technology with CTEK’s trusted reliability, the US 0.8 ensures your batteries stay in peak condition for longer.
This compact, fully automatic 6-step charger delivers up to 0.8A of precise, controlled power to safely charge 12V lead-acid batteries from 1.2Ah to 32Ah, and can maintain larger batteries up to 100Ah.

It’s completely safe for vehicle electronics, non-sparking, short-circuit proof, and reverse-polarity protected, giving you worry-free operation in any environment.
Its IP65-rated splash- and dustproof housing makes it ideal for outdoor use—even in rain or snow—while CTEK’s patented desulphation and maintenance modes help recover and preserve battery performance over time.
Delivered with both alligator clamps and eyelet connectors, the US 0.8 offers convenience, durability, and versatility in one small but powerful package. Backed by a 5-year warranty, it’s the ultimate choice for maintaining smaller batteries safely and efficiently.
