offer professional rebuilds for power tool and laptop packs.

| Function | Description | |----------|-------------| | | Applies a low current (<100mA) to raise cell voltage above BMS minimum threshold (often 2.0V–2.5V). | | PF (Permanent Failure) reset | Clears safety flags like "Cell imbalance," "Over-discharge," or "Short circuit" stored in BMS EEPROM. | | Capacity re-learning | Forces a full charge-discharge cycle to update the battery's "Full Charge Capacity" (FCC) register. | | Cell balancing | Drains high-voltage cells until all cells are within 10–30mV. | | Firmware unlocking | Some batteries (e.g., Dell) require a special handshake to exit "sealed mode." The UBRT2300 injects this handshake. | ubrt2300 universal battery repair tools
