Owners of supported ThinkPad models

Users with a listed ThinkPad needing a direct 57 Wh replacement will find the correct voltage, capacity and physical fit. Buyers whose laptop requires a different watt-hour rating, a higher cell count or a form factor not covered by the 40Y6795 and 92P1137 part-number groups should look elsewhere. The battery is not suitable for models outside the specified R, T, W, Z and SL series or for machines with screen sizes other than 14.1 in, 15.0 in or 15.4 in.

57 Wh capacity decision

The single specification that determines fit is the 57 Wh energy rating combined with the 10.8 V nominal voltage and the six-cell Samsung lithium-ion construction. Match this capacity and voltage to the original battery label or the listed FRU numbers such as 42T4504, 42T4511 or 92P1137 to confirm compatibility before purchase.
