CTEK Comfort Connect Indicator Eyelet — 12V Battery Status Eyelet for Seasonal Vehicles, Permanent Mount

CTEK Comfort Connect Indicator Eyelet (56-382) is a compact battery status eyelet that shows a battery's charge condition and enables easy, permanent connection for maintenance chargers on motorcycles, lawn mowers, jet skis and other hard-to-reach batteries.

The Comfort Indicator Eyelet is a small, durable accessory designed to simplify battery care by providing a visible, at-a-glance indication of a battery’s state and a reliable connection point for compatible CTEK chargers. Built for vehicles and equipment stored for seasonal use, this eyelet makes ongoing maintenance straightforward without repeatedly removing battery covers or terminals. It fits a range of CTEK chargers — including US 800, MULTI US 3300, MULTI US 7002, US 0.8, and MUS 4.3 — and is intended for permanent installation where access is limited.

How does the Comfort Indicator show battery condition?

The indicator displays the battery’s status through a visible signaling element that reflects charge and early-stage sulfation. It gives an immediate visual cue so you can decide whether the battery needs charging or continued maintenance. This helps you act before the battery degrades further.

• Visible indicator built into the eyelet for quick checks
• Signals early signs of harmful sulfation so you can address issues sooner
• Works as a constant monitor when connected to a compatible charger

Can I leave it installed on seasonal vehicles like mowers and jet skis?

Yes — the Comfort Indicator is designed for permanent installation, making it ideal for machines that are stored between seasons. Once fitted to the battery terminal, it allows you to leave a charger connected without having to remove the battery or expose terminals repeatedly. This reduces corrosion from repeated handling and keeps the battery ready for use.

• Permanently mounts to the battery for hassle-free long-term use
• Simplifies seasonal maintenance for motorcycles, lawn mowers, and watercraft
• Reduces wear from frequent terminal removal and reconnection

Which chargers and battery types is the eyelet compatible with?

The Comfort Connect Indicator is made to interface with multiple CTEK chargers and works with standard vehicle lead-acid batteries commonly used in small engines and powersports. It pairs directly with specific CTEK models for reliable charging, monitoring, and maintenance without extra adapters. Confirm compatibility with your charger model before purchase.
