Product Details
For large battery wholesalers and overseas parts hubs, keeping a high-volume stockroom active is a major challenge. Batteries that spend weeks in maritime shipping or sit dormant on shelves will naturally self-discharge, leading to irreversible cell sulfation.
The KOMCO automatic battery charger and maintainer serves as the ultimate maintenance station to eliminate this inventory risk. Featuring an advanced isolation transformer and a bridge rectifier, it converts mains power into a stable, pulsing DC output that refreshes high-voltage blocks effortlessly. Stockroom teams can set the multi-voltage knob to charge individual batteries or connected bank systems in series without manual supervision.
The smart processor continuously tracks saturation, automatically halting power when the green indicator turns on and the current falls to zero, ensuring zero-risk warehouse operations.
