【4-Bank Independent Charging】 Charge and maintain up to four batteries simultaneously with 8A total output and 2A per bank. Each bank features its own MODE and START/STOP controls, allowing you to set and operate every connected battery separately.

【Independent 6V/12V Battery Modes】 Each charging bank can be individually set to 6V AGM, 6V STD, 12V AGM, or 12V STD. Designed for compatible rechargeable lead-acid batteries used in cars, motorcycles, ATVs, RVs, lawn equipment, seasonal vehicles, and backup battery systems.

【9-Stage Intelligent Automatic Charging】 The smart charging system analyzes battery condition and automatically manages the charging process. It detects, charges, activates Recondition Mode when needed, and enters Maintenance Mode after the battery reaches full charge.

【Automatic Recondition & Smart Maintenance】 Recondition Mode automatically activates or exits according to the battery condition. After full charge, Maintenance Mode continuously monitors battery voltage and resumes charging when voltage drops to 6.3V for a 6V battery or 12.6V for a 12V battery.

【Battery Activation for Weak Batteries】 For weak lead-acid batteries above 0.5V that cannot begin normal charging, press and hold the corresponding START/STOP button for 5 seconds to enter Battery Activation Mode. Always verify polarity, battery type, and nominal voltage before activation.

【Clear Status & Fault Diagnostics】 Dedicated Charge, Bad, Fault, and Reverse indicators provide clear feedback for every charging bank. Charging automatically stops when the charger detects reverse polarity, a short circuit or poor connection, an incorrect voltage setting, or a defective battery.

【Easy-to-Read LED Display】 The individual LED indicators show charging mode, battery type, charging status, and fault information for each bank. After 10 minutes of inactivity, the display automatically reduces the number of illuminated LEDs to conserve energy and wakes with one button press.

【Garage-Ready Installation & Connection Options】 Built-in wall-mounting holes help keep garage and workshop charging areas organized. Four battery clamp leads provide quick temporary connections, while four O-ring terminal leads support convenient long-term battery maintenance.
