It is important to clarify upfront that is not a standard technical term found in engineering datasheets or manufacturer documentation.
| 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 | 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. battery eeprom works 327 link full

Typical battery data map (example – Dell/LG/Sanyo): It is important to clarify upfront that is
| Chip family | Capacity (bits) | Decimal representation | |-------------|----------------|------------------------| | 24C32 | 32768 bits | 327 | | 24C64 | 65536 bits | 655 | | 93C86 | 16384 bits? | Some models 16K (no) – actually 93C86 is 16Kbits (not 327) | Common EEPROMs used in batteries: Typical battery data
The more precise match: → 32768 bits → shorthand 327 in some repair communities.
For most consumer electronics, resetting the EEPROM extends battery life by 1–2 years, but after 500 cycles, consider replacing the cells themselves. The “327 link full” is not magic — it’s just the key to unlock your battery’s memory.
