Full Product Description

7-Stage Automatic Charging for Battery Maintenance

This charger utilizes a microprocessor-controlled 7-stage charging process. Once the battery is fully charged, the intelligent system automatically enters a maintenance/float stage, adjusting the charging state as needed. This makes it highly suitable for maintaining batteries in vehicles parked for extended periods, such as weekend cars or winterized motorcycles, ensuring they are always ready to start.

Wide Compatibility with 12V and 24V Systems

This device supports both 12V and 24V systems across various chemistries, including standard Lead-Acid, AGM/Gel, Lithium, and LiFePO4. Please note the capacity limits: it supports 12V batteries from 6Ah to 120Ah, and 24V batteries from 6Ah to 60Ah. For standard cars and motorcycles, it offers seamless charging, but for large 24V commercial vehicles, capacity verification is required before use.

Technician Tip

If your battery voltage is low (but above the 8V minimum start voltage) or showing signs of sulfation, you can try the Repair mode. This mode assists in revitalizing aging or idle batteries over a 16 to 24-hour cycle. However, please note that repair effectiveness depends entirely on the actual condition of the battery. It cannot restore severely damaged or completely dead batteries. If you are unsure about your battery's health, visit our physical store at Sun Cheong Computer Co. Ltd. in Sham Shui Po for professional advice.

FAQ Section

Can I leave this charger connected to my car over the winter?

Yes. The 7-stage intelligent charging system enters a maintenance/float stage upon completion, automatically adjusting the charging state. This makes it suitable for long-term battery maintenance, especially for weekend cars or motorcycles parked for extended periods.

Can this be used to charge 24V truck batteries?

This product supports 24V battery systems with a rated output of 3A. However, you must ensure your battery capacity falls within the product's specifications (6-60Ah for 24V). For large 24V commercial truck battery banks, please consult us before purchasing to confirm compatibility.

How should I use the Repair mode for low voltage or sulfated batteries?

You can try using the Repair mode on the front panel. This mode assists in repairing aging, long-idle, or sulfated car and motorcycle batteries, running for approximately 16 to 24 hours. However, the repair effectiveness depends on the actual condition of the battery, and not all batteries can be fixed. If the battery is severely damaged or completely dead, replacement is recommended.

What happens if I accidentally reverse the red and black clamps?

This charger features reverse polarity protection. If the positive and negative terminals are reversed, the charger will stop normal output and prompt a wiring error. You should turn off the power, confirm the correct polarity, and then reconnect the clamps.

Is the plug suitable for Hong Kong sockets?

Yes. This product supports 100-240V AC, 50-60Hz input and comes equipped with a standard UK plug. It is perfectly suitable for standard 3-pin sockets in Hong Kong without the need for an additional voltage converter.
