Check a compatible 12V lead-acid battery through an accessory socket using the CTEK 56-870 Comfort Indicator Cig Plug. Its LEDs show battery charge status. The socket must remain powered when the ignition is off.

Compatibility & Specifications

Manufacturer Part Number 56-870
Battery System 12V lead-acid
Connection Requirements Compatible 12mm or 21mm 12V socket that remains live with the ignition off
Function CTEK CONNECT interface for a compatible CTEK charger up to 7A; confirm the vehicle permits charging through its socket

Compatibility follows the battery system, connection and equipment requirements. Vehicle year, make and model alone do not establish fit.

Can it work through a switched-off accessory socket?

No. The socket must stay connected to battery power with the ignition off. Check socket and vehicle charging restrictions before use.

Installation & Use

Follow the manufacturer's instructions for the exact part number. Check polarity, secure the connections and protect leads from heat, abrasion and moving parts. A charge-status reading does not measure remaining battery capacity or replace a suitable load or conductance test.

Battery testers, voltage indicators and battery monitors help you check a vehicle battery before the next drive. Explore CTEK Comfort Indicator leads and the Antigravity Bluetooth Battery Tracker at Black Ops Auto Works. Choose a quick LED charge-status check, a permanent monitoring connection or app-based voltage history for a compatible 12V lead-acid battery. Start with what you need to learn. Checking whether a stored battery needs charging is different from measuring cranking performance or diagnosing a starting problem. The products in this collection focus on battery status and monitoring. They do not all perform the same tests, and an LED indicator is not a replacement for a dedicated battery load tester. 12V Battery Status Indicators for Cars & Stored Vehicles A battery status indicator provides a convenient check between drives, especially when the battery is hidden or difficult to reach. CTEK Comfort Indicator accessories use LEDs to show when a compatible battery may...
