The EEPROM stores data in blocks or pages (24C32 has 128 pages × 32 bytes = 4096 bytes).
Typical battery data map (example – Dell/LG/Sanyo):
| Address (hex) | Description | Example value | |---------------|---------------------------|----------------------| | 0x00-0x07 | Battery manufacturer ID | 0x4C 0x47 (LG) | | 0x20-0x21 | Cycle count | 0x01 0x2C (300) | | 0x40-0x43 | Full charge capacity (mAh)| 0x00 0xFA (2500 mAh) | | 0x7F0-0x7FF | Checksum / signature | 0xA5 0x5A | battery eeprom works 327 link full
If you found a working “full link” with software and instructions, here is the generic procedure.
| Device type | Example model | EEPROM chip | |------------------|---------------------------|----------------| | Laptop | Dell XPS 15 9560 battery | 24C32 (327) | | Power tool | Makita 18V LXT 5Ah | 24C32 (327) | | Medical battery | Philips HeartStart | BR24G32 | | E-bike battery | Bosch PowerTube 500 | 24C32 | The EEPROM stores data in blocks or pages
While this tool is valuable for repair, it carries significant risks:
Since 32768 bits = 4096 bytes, the address range is 0x000 to 0xFFF (12-bit addressing). The last page (0xFF0 to 0xFFF) often contains authentication data. The “link full” in your search likely points
Many battery replacements fail because the EEPROM checksum is tied to the cycle count. Change the cycle count without updating the checksum → battery reports “invalid.”
Several tools exist:
The “link full” in your search likely points to a mirror of these tools plus a collection of known-good EEPROM dumps for specific battery models (e.g., ASUS A31N1519, Lenovo 45N1113, Milwaukee M18).
