EAFC 6853D 1.5A Fully-Automatic Smart Charger, 12V Portable Automotive Car Battery Charger

Overview

The EAFC 1.5A Fully-Automatic Smart Charger is a portable 12V automotive battery charger, maintainer, trickle charger, and desulfator with temperature compensation. It is designed for all types of 12-volt lead-acid batteries, including Wet, Gel, and AGM. The charger uses a microprocessor-controlled program to monitor the charging process and automatically adjust output.

Key capabilities:

• Fully-automatic 4-stage charging (25% / 50% / 75% / 100% LED indication)
• Battery maintainer / trickle charge mode for long-term storage
• Desulfation function to prevent battery stratification and sulfation
• Temperature compensation for safe charging in varying conditions
• Multi-protection: reverse polarity, over-temperature, overcharge, short circuit, low/high voltage

Compatible applications: automobiles, marine, boats, campers, trolling motors, watercraft, riding lawnmowers, lawn tractors, snowmobiles, and more.

Specifications

Features

4-Stage Automatic Charging

The charger constantly monitors the battery level and automatically adjusts the converter output voltage based on the battery’s charge status. The LED indicator displays the charging status at four levels: 25%, 50%, 75%, and 100%. When the battery is fully charged, the charger stops automatically.

Battery Maintainer / Trickle Charge Mode

After full charge, the unit automatically switches to maintenance mode with a constant pulse current. This keeps the battery at an optimal level and is ideal for long-term storage, preventing battery stratification and sulfation.

Desulfation Function

The charger includes a desulfation feature that helps break down sulfate crystals on battery plates, extending battery life and restoring capacity.

Temperature Compensation

Built-in temperature compensation adjusts the charging voltage based on ambient temperature, ensuring safe and efficient charging in hot or cold conditions.

Multi-Protection Safety

Smart circuits provide multiple layers of protection:

• Reverse polarity protection
• Over-temperature protection
• Overcharge protection
• Short circuit protection
• Low and high voltage protection

Easy Plug-and-Use Operation

No manual settings required. Simply connect the clips to the battery, plug the charger into a standard AC outlet, and the microprocessor automatically manages the entire charging cycle.

Indicators and Controls

Note: The charger has no physical buttons or switches. All operations are fully automatic.

Use Guide

Before You Start

• Ensure the battery is 12V lead-acid type (Wet, Gel, AGM). Do not use with lithium batteries unless specified.
• Place the charger on a stable, dry surface away from moisture and flammable materials.
• Inspect the clip connectors cable for damage before each use.

Step-by-Step Charging

1. Connect the clips to the battery: Attach the red clip to the positive (+) terminal and the black clip to the negative (-) terminal. Ensure a secure connection.
2. Plug in the charger: Connect the charger to a standard 12V AC power outlet. The LED indicators will light up to show the current charge level.
3. Monitor the charging process: The LEDs will progress from 25% → 50% → 75% → 100% as the battery charges. The charger automatically stops when full charge is reached.
4. Maintenance mode: After reaching 100%, the charger enters maintenance mode (pulse current) to keep the battery topped off. You can leave it connected indefinitely.
5. Disconnect: Unplug the charger from the AC outlet first, then remove the clips from the battery terminals (black first, then red).

Using as a Battery Maintainer

For long-term storage (e.g., seasonal vehicles), leave the charger connected to the battery. The unit will automatically maintain the charge and prevent sulfation. Ensure the area is well-ventilated and the charger is not covered.

Desulfation Mode

If the battery is deeply discharged or sulfated, the charger may enter a desulfation phase (indicated by a specific LED pattern). This can take several hours. Do not interrupt the process unless necessary.
