AIYONFEI 12V 10A Battery Charger – 9-Stage Smart Trickle with LED Display

All-in-One 12V Battery Care for Everyday Rides and Seasonal Storage

The AIYONFEI 12V 10A Battery Charger is designed to be more than a charger. It acts as a complete battery companion, capable of charging, maintaining, desulfating, and rejuvenating 12V packs across a broad range of chemistries. Whether you’re topping up a car battery after a winter layover, keeping a marine or lawn-tractor battery healthy, or managing a growing fleet of motorcycles, this unit aims to simplify care with one tool.

With 10A of charging power and a 9-stage smart program, you can expect faster, safer top-ups while protecting long-term battery health. The charger supports 12V packs from 2Ah up to 150Ah and remembers your last mode after a power outage, so your setup stays familiar when power returns.

Climate-Responsive Charging and Clear Status

Automatic winter and summer modes adjust charging voltage according to ambient temperature, helping maintain safe, efficient charging across seasons. An LED touch display provides real-time reads of voltage, current, and status, making operation straightforward even for casual users.

Desulfation, Maintenance, and Gentle Recovery

In maintenance mode, pulse repair technology can help activate and extend the life of aging batteries that still hold a charge, while avoiding aggressive treatment. Note that this mode is not suitable for completely depleted, damaged, or lithium batteries.

Trickle Charging, Seasonal Care, and Safety

For long-term care of seasonal vehicles, switch to trickle charging or motorcycle mode. The unit includes protection against reverse polarity, overcharging, overvoltage, and short circuits. Trickle flow and TKL modes are not compatible with LiFePO4 batteries.

Notes, Compatibility, and Support

Basic details: this is a 12V charger designed for 12V car or motorcycle batteries (not 24V). It requires a mains power outlet to operate; cord lengths are 150 cm for the input and 90 cm for the output. If the indicator icon shows empty, no battery has been detected. A complete user manual is included, and our team offers prompt 24/7 support for questions or setup guidance.
