Once the green light turns on, the smart circuitry monitors the battery’s self-discharge rate. If the battery voltage drops below a preset threshold, the charger kicks back on automatically to top it off. You can leave this charger connected throughout the winter months without risking boiling or warping the internal battery plates. Troubleshooting Common Issues The LED lights do not turn on at all
: Attach directly to the negative (-) terminal.
The battery is too large for a 1.5 Amp charger, or the battery has a shorted internal cell.

Connect the black (negative) clamp to a heavy, unpainted metal part of the vehicle frame or engine block (away from the battery). If the battery is out of the vehicle, connect directly to the negative (-) post.
: Most models feature an LED that glows solid or flashes to indicate charging status.
Pro tip: If the error light flashes in a repeating pattern (e.g., 2 flashes, pause), consult the manual’s code list — but generally, it means voltage under 3V or over 15V.
: Verify the wall outlet works by plugging in a different appliance. Ensure the quick-disconnect plug between the clamps and the charger body is firmly snapped together. The Red light flashes continuously Cause : Reverse polarity or a bad battery. Once the green light turns on, the smart
The Autocraft 1.5 Amp charger uses simple LED light prompts to communicate the current state of your battery.
Since this is a 1.5 amp charger/maintainer, it is designed for slower, safe charging rather than rapid boosts.
The Autocraft 1.5 Amp battery charger and maintainer is designed to keep lead-acid batteries—like those found in cars, motorcycles, and RVs—at peak performance. It is a fully automatic device that prevents overcharging by switching to a "float" or "maintenance" mode once the battery is full. 🛠️ Operating Instructions
: The battery is charged to roughly 80% capacity and is completing its final top-off stage. Troubleshooting Common Issues The LED lights do not
Advance Auto Parts does not keep PDFs of older AutoCraft manuals online, but you can:
| Light | Status | Meaning | | :--- | :--- | :--- | | | On | The charger is properly connected to the AC power outlet. | | CHARGING (Yellow) | On | The battery is connected correctly and is being charged. | | | Flashing | The charger has entered Desulfation Mode . This process can take 8-10 hours and attempts to restore heavily discharged batteries. If it fails, the charging process will be aborted. | | CHARGED (Green) | On (Solid) | The battery is fully charged, and the charger has automatically switched to Maintain Mode (Float-Mode). It will now keep the battery at full charge with a small current when needed. |
To clean, unplug the unit and use a dry cloth. Inspect cables regularly for damage. 6. Frequently Asked Questions
