Flex-3 Compatibility Note

Q: Does 45N1110 fit ThinkPad X220, X230, or T430?
No. The 45N1110/45N1108 (11.1V, 24Wh, 3-cell internal) is designed exclusively for the ThinkPad X240–X270 and T440–T450 series that support internal + external dual-battery setups. Earlier models like the X220 (external 29++, 0A36282), X230 (44++, 0A36305), and T430 (70+, 0A36303) use external-only batteries with different connectors and voltage rails. Always verify your exact ThinkPad model number before ordering.
