Lenovo and IBM Battery Part Number Identification

Lenovo and IBM replacement batteries may list several useful identifiers, including battery model codes, FRU numbers and ASM numbers. These codes are excellent search terms because ThinkPad and IdeaPad model names can cover multiple battery options.

Quick steps

1. Power off the laptop and remove the charger.
2. Remove the battery if it is removable, or inspect the internal battery label safely.
3. Look for FRU, ASM, P/N, Model or barcode text.
4. Copy the complete code, including any leading zero, dash or space.
5. Search by FRU, ASM or battery model number, then compare voltage, shape and compatible model list.

Compatibility tip: For ThinkPad batteries, FRU numbers are especially useful. If several compatible FRU numbers are listed on a product page, any of them may identify the same replacement family.
