Questions about this item

Does the L21M4PE1 battery package include any tools or cables for installation?

The listing describes the battery unit only; no tools, cables or extra hardware are mentioned, so plan to reuse the screws and connector from the original battery when swapping it in your Legion or Yoga laptop.

My original battery is marked L21C4PE1 — is the L21M4PE1 the correct replacement?

Yes, the L21M4PE1 replaces part numbers L21C4PE1, L21B4PE1, SB11F29419, 5B11F29413 and several others listed for the Legion S7 16IAH7, Legion S7 16ARHA7 and Yoga 7 16IAH7 series.

What runtime can I expect from the 99.99 Wh rating on a Legion S7 16IAH7?

The 99.99 Wh capacity matches the factory specification for these models; actual run time depends on screen brightness, workload and power settings, but the battery is designed to deliver the same watt-hour capacity as the original pack.
