Battery Eeprom Works 327 Link Full [upd] -

Common EEPROMs used in batteries:

| 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): Common EEPROMs used in batteries: | Address (hex)

It is important to clarify upfront that is not a standard technical term found in engineering datasheets or manufacturer documentation. The more precise match: → 32768 bits →

The more precise match: → 32768 bits → shorthand 327 in some repair communities.

| 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) |
